This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||||
|
||||
## Development Commands
|
||||
|
||||
This project uses pnpm as the package manager and Turbo for build orchestration:
|
||||
|
||||
- `pnpm install` - Install all dependencies
|
||||
- `pnpm build` - Build all packages using Turbo
|
||||
- `pnpm dev` - Start development mode for all packages
|
||||
- `pnpm test` - Run all unit tests
|
||||
- `pnpm e2e` - Run end-to-end tests
|
||||
- `pnpm lint` - Run ESLint across all packages
|
||||
- `pnpm type-check` - Run TypeScript type checking across workspace
|
||||
- `pnpm format` - Check code formatting with Prettier
|
||||
- `pnpm format:write` - Auto-fix formatting issues
|
||||
- `pnpm circular-check` - Check for circular dependencies using madge
|
||||
|
||||
For individual package development:
|
||||
|
||||
- `turbo run build --filter="@llamaindex/core"` - Build specific package
|
||||
- `turbo run test --filter="@llamaindex/core"` - Test specific package
|
||||
- Navigate to specific package directory and run `pnpm test` for focused testing
|
||||
- `pnpm clean` - Remove all build artifacts and node_modules across workspace
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
LlamaIndex.TS is a TypeScript data framework for LLM applications organized as a pnpm monorepo with multiple runtime environment support (Node.js, Deno, Bun, Vercel Edge, Cloudflare Workers).
|
||||
|
||||
### Package Structure
|
||||
|
||||
**Core Packages:**
|
||||
|
||||
- `packages/core/` - Abstract base classes and interfaces for all runtime environments
|
||||
- `packages/llamaindex/` - Main package that aggregates core functionality
|
||||
- `packages/env/` - Environment-specific compatibility layers for different JS runtimes
|
||||
|
||||
**Provider Packages (`packages/providers/`):**
|
||||
|
||||
- LLM providers: `openai/`, `anthropic/`, `ollama/`, `google/`, `groq/`, etc.
|
||||
- Vector stores: `storage/pinecone/`, `storage/chroma/`, `storage/qdrant/`, etc.
|
||||
- Embeddings: Various embedding providers integrated within LLM packages
|
||||
- Readers: `assemblyai/`, `discord/`, `notion/` for data ingestion
|
||||
|
||||
**Specialized Packages:**
|
||||
|
||||
- `packages/cloud/` - LlamaCloud integration for managed services
|
||||
- `packages/tools/` - Function calling tools and utilities
|
||||
- `packages/workflow/` - Agent workflow orchestration
|
||||
- `packages/readers/` - File format readers (PDF, DOCX, etc.)
|
||||
|
||||
### Key Architectural Patterns
|
||||
|
||||
**Runtime Abstraction:** Core functionality is runtime-agnostic, with environment-specific implementations in separate entry points (`index.ts`, `index.edge.ts`, `index.workerd.ts`).
|
||||
|
||||
**Provider Pattern:** LLMs, embeddings, and vector stores implement common interfaces from `@llamaindex/core`, allowing easy swapping between providers.
|
||||
|
||||
**Modular Design:** Each provider is a separate package to minimize bundle size - users install only what they need.
|
||||
|
||||
**Data Flow:** Document → NodeParser → Embedding → VectorStore → Retriever → QueryEngine → Response
|
||||
|
||||
### Core Components
|
||||
|
||||
- **Agents and Workflows:** Abstractions for building agentic workflows and agents in `packages/workflow`
|
||||
- **Chat Engines:** Conversational interfaces in `core/chat-engine/`
|
||||
- **Query Engines:** Document querying with retrieval in `core/query-engine/`
|
||||
- **Indices:** VectorStoreIndex, SummaryIndex, KeywordTable in `llamaindex/indices/`
|
||||
- **Node Parsers:** Text splitting and chunking in `core/node-parser/`
|
||||
- **Ingestion Pipeline:** Document processing workflows in `llamaindex/ingestion/`
|
||||
- **Storage:** Chat stores, document stores, index stores, and KV stores in `core/storage/`
|
||||
|
||||
### Deprecated Components
|
||||
|
||||
- **Agents:** ReAct and function calling agents in `core/agent/` and `llamaindex/agent/`
|
||||
|
||||
### Testing Structure
|
||||
|
||||
- Unit tests in each package's `tests/` directory
|
||||
- E2E tests in `e2e/` directory with runtime-specific examples
|
||||
- Tests depend on build artifacts, so always run `pnpm build` before testing
|
||||
|
||||
### Multi-Runtime Support
|
||||
|
||||
The codebase supports multiple JavaScript runtimes through conditional exports and separate entry points. When making changes, consider compatibility across Node.js, Deno, Bun, and edge runtimes.
|
||||
|
||||
### Development Notes
|
||||
|
||||
- The project uses Husky for git hooks with lint-staged for pre-commit formatting and linting
|
||||
- All packages use bunchee for building with dual CJS/ESM support
|
||||
- Core package exports are organized as sub-modules (e.g., `@llamaindex/core/llms`, `@llamaindex/core/embeddings`)
|
||||
- Always run `pnpm build` before running tests, as tests depend on build artifacts

### Start Developing
|
||||
|
||||
You can launch the package in dev-mode by running:
|
||||
|
||||
```shell
|
||||
pnpm dev
|
||||
```
|
||||
|
||||
This will use turbo to run all packages in watch-mode. This means you can make changes and have them automatically built.
|
||||
|
||||
If you want to customize what packages are built/watched, you can run turbo directly and adjust the filter:
|
||||
|
||||
```shell
|
||||
pnpm turbo run dev --filter="./packages/core" --concurrency=100
|
||||
```
|
||||
|
||||
In another terminal, you can write and run any script needed to quickly test your changes. For example:
|
||||
|
||||
```typescript
|
||||
import { createMemory, staticBlock } from "@llamaindex/core/memory";
|
||||
|
||||
// Create memory with predefined context
|
||||
const memory = createMemory({
|
||||
memoryBlocks: [
|
||||
staticBlock({
|
||||
content:
|
||||
"The user is a software engineer who loves TypeScript and LlamaIndex.",
|
||||
messageRole: "system",
|
||||
}),
|
||||
],
|
||||
});
|
||||
|
||||
async function main() {
|
||||
const result = await memory.getLLM();
|
||||
console.log(result);
|
||||
}
|
||||
|
||||
void main().catch(console.error);
|
||||
```
|
||||
|
||||
And run it with:
|
||||
|
||||
```shell
|
||||
pnpm exec tsx my_script.ts
|
||||
```
|
||||
|
||||
This flow allows you to easily test your changes without having to build the entire project.
|
||||
|
||||
Once you are happy with your changes, be sure to add tests (and confirm existing tests are passing!).

|
||||
## Core concepts for getting started:
|
||||
|
||||
See our documentation: https://ts.llamaindex.ai/docs/llamaindex/getting_started/concepts
|
||||
- [Document](/packages/llamaindex/src/Node.ts): A document represents a text file, PDF file or other contiguous piece of data.
|
||||
|
||||
- [Node](/packages/llamaindex/src/Node.ts): The basic data building block. Most commonly, these are parts of the document split into manageable pieces that are small enough to be fed into an embedding model and LLM.
|
||||
|
||||
- [Embedding](/packages/llamaindex/src/embeddings/OpenAIEmbedding.ts): Embeddings are sets of floating point numbers which represent the data in a Node. By comparing the similarity of embeddings, we can derive an understanding of the similarity of two pieces of data. One use case is to compare the embedding of a question with the embeddings of our Nodes to see which Nodes may contain the data needed to answer that question. Because the default service context is OpenAI, the default embedding is `OpenAIEmbedding`. If using different models, say through Ollama, use this [Embedding](/packages/llamaindex/src/embeddings/OllamaEmbedding.ts) (see all [here](/packages/llamaindex/src/embeddings)).
|
||||
|
||||
- [Indices](/packages/llamaindex/src/indices/): Indices store the Nodes and the embeddings of those nodes. QueryEngines retrieve Nodes from these Indices using embedding similarity.
|
||||
|
||||
- [QueryEngine](/packages/llamaindex/src/engines/query/RetrieverQueryEngine.ts): Query engines are what generate the query you put in and give you back the result. Query engines generally combine a pre-built prompt with selected Nodes from your Index to give the LLM the context it needs to answer your query. To build a query engine from your Index (recommended), use the [`asQueryEngine`](/packages/llamaindex/src/indices/BaseIndex.ts) method on your Index. See all query engines [here](/packages/llamaindex/src/engines/query).
|
||||
|
||||
- [ChatEngine](/packages/llamaindex/src/engines/chat/SimpleChatEngine.ts): A ChatEngine helps you build a chatbot that will interact with your Indices. See all chat engines [here](/packages/llamaindex/src/engines/chat).
|
||||
|
||||
- [SimplePrompt](/packages/llamaindex/src/Prompt.ts): A simple standardized function call definition that takes in inputs and formats them in a template literal. SimplePrompts can be specialized using currying and combined using other SimplePrompt functions.

# CLAUDE.md
|
||||
|
||||
This file provides guidance to Claude Code (claude.ai/code) when working with the LlamaIndex.TS documentation site.
|
||||
|
||||
## Application Overview
|
||||
|
||||
This is a Next.js documentation site (`@llamaindex/doc`) that serves as the official documentation for LlamaIndex.TS. It's built using Fumadocs, a modern documentation framework, and includes interactive features, API documentation generation, and AI-powered chat functionality.
|
||||
|
||||
## Development Commands
|
||||
|
||||
From this directory (`apps/next/`):
|
||||
|
||||
- `pnpm dev` - Start development server with Turbo
|
||||
- `pnpm build` - Build the documentation site (includes `prebuild` step)
|
||||
- `pnpm start` - Start production server
|
||||
- `pnpm build:docs` - Generate API documentation from TypeScript source
|
||||
- `pnpm validate-links` - Validate all internal and external links
|
||||
|
||||
Key build process:
|
||||
|
||||
1. `prebuild` runs `build:docs` to generate API documentation using TypeDoc
|
||||
2. `build` runs Next.js build process
|
||||
3. `postbuild` runs post-processing scripts and link validation
|
||||
|
||||
## Architecture
|
||||
|
||||
### Framework Stack
|
||||
|
||||
- **Next.js 15.3** - React framework with App Router
|
||||
- **Fumadocs** - Documentation framework with MDX support
|
||||
- **React Server Components** - AI chat functionality with server actions
|
||||
- **Tailwind CSS** - Styling with custom design system
|
||||
- **TypeScript** - Full type safety
|
||||
|
||||
### Key Dependencies
|
||||
|
||||
- **Fumadocs ecosystem**: `fumadocs-ui`, `fumadocs-mdx`, `fumadocs-core`, `fumadocs-openapi`
|
||||
- **AI features**: `ai` package for React Server Components chat
|
||||
- **Code features**: Monaco Editor, Shiki syntax highlighting, Twoslash TypeScript integration
|
||||
- **UI components**: Radix UI primitives, Framer Motion animations
|
||||
- **Content processing**: MDX, remark/rehype plugins, TypeDoc for API generation
|
||||
|
||||
### Directory Structure
|
||||
|
||||
**Content Management:**
|
||||
|
||||
- `src/content/docs/` - MDX documentation files organized by topic
|
||||
- `src/content/docs/api/` - Auto-generated API documentation from TypeScript
|
||||

||||
- `src/app/` - Next.js App Router pages and API routes
|
||||
- `src/components/` - Reusable React components including UI library
|
||||
- `src/lib/` - Utilities, constants, and configuration
|
||||
|
||||
**Configuration:**
|
||||
|
||||
- `source.config.ts` - Fumadocs MDX configuration with plugins
|
||||
- `next.config.mjs` - Next.js configuration with MDX integration
|
||||
- `tailwind.config.mjs` - Tailwind CSS customization
|
||||
|
||||
### Key Features

|
||||
- Custom scripts transform and validate generated content
|
||||
- Link checking ensures all internal/external links work
|
||||
- Static site generation with 10-minute timeout for large documentation set
|
||||
|
||||
### Configuration Files

|
||||
|
||||
### Content Organization
|
||||
|
||||
**Documentation Structure:**
|
||||
|
||||
- `/docs/llamaindex/` - Core LlamaIndex.TS documentation
|
||||

|
||||
- External docs from `@llamaindex/workflow-docs` package
|
||||
- Generated API docs from TypeScript source
|
||||
|
||||
### Development Notes
|
||||
|
||||
- Documentation content is sourced from multiple locations including external packages
|
||||
- API documentation is regenerated on each build from TypeScript source
|
||||
- The site uses advanced MDX features including custom transformers and plugins
|
||||
- Build process includes comprehensive link validation
|
||||
- Large memory allocation needed for TypeDoc generation (`--max-old-space-size=8192`)
|
||||
- Chat functionality uses React Server Components with streaming responses
|
||||
|
||||
### AI Chat Integration
|
||||
|
||||
The documentation includes an AI chat feature that:
|
||||
|
||||
- Uses React Server Components for server-side AI processing
|
||||
- Integrates with LlamaIndex.TS packages for demonstrations
|
||||
- Provides interactive examples and code generation
|
||||
- Streams responses for better user experience
|
||||
|
||||
### Content Authoring
|
||||
|
||||
When adding new documentation:
|
||||
|
||||
- Create MDX files in appropriate `src/content/docs/` subdirectories
|
||||
- Follow existing content structure and frontmatter conventions
|
||||
- Use Fumadocs MDX features like code blocks, callouts, and tabs
|
||||
- API documentation is auto-generated - edit TypeScript source comments instead
|
||||
- Run `pnpm validate-links` to check all links before publishing

title: High-Level Concepts
|
||||
---
|
||||
|
||||
This is a quick guide to the high-level concepts you'll encounter frequently when building LLM applications.
|
||||
|
||||
## Large Language Models (LLMs)
|
||||
|
||||
LLMs are the fundamental innovation that launched LlamaIndex. They are an artificial intelligence (AI) computer system that can understand, generate, and manipulate natural language, including answering questions based on their training data or data provided to them at query time.
|
||||
|
||||
## Agentic Applications
|
||||
|
||||
When an LLM is used within an application, it is often used to make decisions, take actions, and/or interact with the world. This is the core definition of an **agentic application**.
|
||||
|
||||
While the definition of an agentic application is broad, there are several key characteristics that define an agentic application:
|
||||
|
||||
- **LLM Augmentation**: The LLM is augmented with tools (i.e. arbitrary callable functions in code), memory, and/or dynamic prompts.
|
||||
- **Prompt Chaining**: Several LLM calls are used that build on each other, with the output of one LLM call being used as the input to the next.
|
||||
- **Routing**: The LLM is used to route the application to the next appropriate step or state in the application.
|
||||
- **Parallelism**: The application can perform multiple steps or actions in parallel.
|
||||
- **Orchestration**: A hierarchical structure of LLMs is used to orchestrate lower-level actions and LLMs.
|
||||
- **Reflection**: The LLM is used to reflect and validate outputs of previous steps or LLM calls, which can be used to guide the application to the next appropriate step or state.
|
||||
|
||||
In LlamaIndex, you can build agentic applications by using the workflows to orchestrate a sequence of steps and LLMs. You can [learn more about workflows](/docs/llamaindex/tutorials/workflows).
|
||||
|
||||
## Agents
|
||||
|
||||
We define an agent as a specific instance of an "agentic application". An agent is a piece of software that semi-autonomously performs tasks by combining LLMs with other tools and memory, orchestrated in a reasoning loop that decides which tool to use next (if any).
|
||||
|
||||
What this means in practice, is something like:
|
||||
- An agent receives a user message
|
||||
- The agent uses an LLM to determine the next appropriate action to take using the previous chat history, tools, and the latest user message
|
||||
- The agent may invoke one or more tools to assist in the users request
|
||||
- If tools are used, the agent will then interpret the tool outputs and use them to inform the next action
|
||||
- Once the agent stops taking actions, it returns the final output to the user
|
||||
|
||||
You can [learn more about agents](/docs/llamaindex/tutorials/basic_agent).
|
||||
|
||||
## Retrieval Augmented Generation (RAG)
|
||||
|
||||
Retrieval-Augmented Generation (RAG) is a core technique for building data-backed LLM applications with LlamaIndex. It allows LLMs to answer questions about your private data by providing it to the LLM at query time, rather than training the LLM on your data. To avoid sending **all** of your data to the LLM every time, RAG indexes your data and selectively sends only the relevant parts along with your query. You can [learn more about RAG](/docs/llamaindex/tutorials/rag).
|
||||
|
||||
## Use cases
|
||||
|
||||
There are endless use cases for data-backed LLM applications but they can be roughly grouped into four categories:
|
||||
|
||||
[**Agents**](/docs/llamaindex/tutorials/basic_agent):
|
||||
An agent is an automated decision-maker powered by an LLM that interacts with the world via a set of [tools](/docs/llamaindex/modules/agents/tool). Agents can take an arbitrary number of steps to complete a given task, dynamically deciding on the best course of action rather than following pre-determined steps. This gives it additional flexibility to tackle more complex tasks.
|
||||
|
||||
[**Workflows**](/docs/llamaindex/tutorials/workflows):
|
||||
A Workflow in LlamaIndex is a specific event-driven abstraction that allows you to orchestrate a sequence of steps and LLMs calls. Workflows can be used to implement any agentic application, and are a core component of LlamaIndex.
|
||||
|
||||
[**Structured Data Extraction**](/docs/llamaindex/tutorials/structured_data_extraction):
|
||||
Pydantic extractors allow you to specify a precise data structure to extract from your data and use LLMs to fill in the missing pieces in a type-safe way. This is useful for extracting structured data from unstructured sources like PDFs, websites, and more, and is key to automating workflows.
|
||||
|
||||
[**Query Engines**](/docs/llamaindex/modules/rag/query_engines):
|
||||
A query engine is an end-to-end flow that allows you to ask questions over your data. It takes in a natural language query, and returns a response, along with reference context retrieved and passed to the LLM.
|
||||
|
||||
[**Chat Engines**](/docs/llamaindex/modules/rag/chat_engine):
|
||||
A chat engine is an end-to-end flow for having a conversation with your data (multiple back-and-forth instead of a single question-and-answer).

title: Define workflows using natural language
|
||||
---
|
||||
|
||||
When working with Workflows, you have to write code to handle an event in the workflow.
|
||||
Often, the logic of the handler is not too complex so that it can be expressed using natural language and executed by an LLM.
|
||||
Besides the instructions, we just need the expected result event of the step, possible tool calls and optionally other events that can be emitted.
|
||||
|
||||
## Usage
|
||||
|
||||
Let's take an example of a workflow that generates a joke, gets a critique for it, and then improves it.
|
||||
|
||||
### Define the events
|
||||
|
||||
First, we define the events for our workflow. We need one for writing the joke, one for critiquing it, and one for the final result:
|
||||
|
||||
```typescript
|
||||
import { z } from "zod";
|
||||
import { zodEvent } from "@llamaindex/workflow";
|
||||
|
||||
const writeJokeSchema = z.object({
|
||||
description: z
|
||||
.string()
|
||||
.describe("The topic to write a joke or describe the joke to improve."),
|
||||
writtenJoke: z.optional(z.string()).describe("The written joke."),
|
||||
retriedTimes: z
|
||||
.number()
|
||||
.default(0)
|
||||
.describe(
|
||||
"The retried times for writing the joke. Always increase this from the input retriedTimes.",
|
||||
),
|
||||
});
|
||||
|
||||
const critiqueSchema = z.object({
|
||||
joke: z.string().describe("The joke to critique"),
|
||||
retriedTimes: z.number().describe("The retried times for writing the joke."),
|
||||
});
|
||||
|
||||
const finalResultSchema = z.object({
|
||||
joke: z.string().describe("The joke to critique"),
|
||||
critique: z.string().describe("The critique of the joke"),
|
||||
});
|
||||
|
||||
const writeJokeEvent = zodEvent(writeJokeSchema, {
|
||||
debugLabel: "writeJokeEvent",
|
||||
});
|
||||
const critiqueEvent = zodEvent(critiqueSchema, {
|
||||
debugLabel: "critiqueEvent",
|
||||
});
|
||||
const finalResultEvent = zodEvent(finalResultSchema, {
|
||||
debugLabel: "finalResultEvent",
|
||||
});
|
||||
```
|
||||
|
||||
Note that your natural language workflows the events need to be created by the `zodEvent` function passing the zod schema as an argument. The agent needs the schema of the event data to correctly generate events.
|
||||
Also, we need a `debugLabel` so the LLM can identify the event to emit in the workflow.
|
||||
|
||||
### Define the workflow
|
||||
|
||||
As usual you first create the workflow:
|
||||
|
||||
```typescript
|
||||
import { agentHandler, createWorkflow } from "@llamaindex/workflow";
|
||||
|
||||
const jokeFlow = createWorkflow();
|
||||
```
|
||||
|
||||
Then you need to handle the events. For the handlers, instead of code, you're now going to use natural language by calling the `agentHandler` function.
|
||||
|
||||
It only requires two parameters:
|
||||
- `instructions`: A prompt to guide the agent how to handle the steps.
|
||||
- `results`: The output events that the agent should return after handling the step.
|
||||
|
||||
Then you will have a simple code to handle the step:
|
||||
|
||||
```typescript
|
||||
jokeFlow.handle(
|
||||
[writeJokeEvent],
|
||||
agentHandler({
|
||||
instructions: `You are a joke writer. You are given a topic and you need to write a joke about it.`,
|
||||
results: [critiqueEvent],
|
||||
}),
|
||||
);
|
||||
|
||||
jokeFlow.handle(
|
||||
[critiqueEvent],
|
||||
agentHandler({
|
||||
instructions: `
|
||||
You are given a joke and you need to critique it. Follow the following guidelines:
|
||||
1. You have maximum 3 times to improve the joke.
|
||||
2. If the joke is not good, increase the retriedTimes, describe how to improve the joke and send a writeJokeEvent.
|
||||
3. If the joke is good, trigger the finalResultEvent event.
|
||||
`,
|
||||
results: [writeJokeEvent, finalResultEvent],
|
||||
}),
|
||||
);
|
||||
```
|
||||
|
||||
For advanced usage, you can add more functionality to `agentHandler` by using these parameters:
|
||||
- `events`: A list of additional events that the agent can emit to the workflow. E.g., your agent can emit a `uiEvent` to update the UI during the execution.
|
||||
- `tools`: A list of tools that the agent can use to handle the step. E.g., your agent can use a `search` tool to search the web.

||||

||||

A `Workflow` in LlamaIndex is a lightweight, event-driven abstraction used to chain together several events. Workflows are made up of `handlers`, with each one responsible for processing specific event types and emitting new events.
|
||||
A `Workflow` in LlamaIndexTS is an event-driven abstraction used to chain together several events. Workflows are made up of `steps`, with each step responsible for handling certain event types and emitting new events.
|
||||
|
||||
Workflows are designed to be flexible and can be used to build agents, RAG flows, extraction flows, or anything else you want to implement.
|
||||
Workflows in LlamaIndexTS work by defining step functions that handle specific event types and emit new events.
|
||||
|
||||
To use workflows install this package:
|
||||
When a step function is added to a workflow, you need to specify the input and optionally the output event types (used for validation). The specification of the input events ensures each step only runs when an accepted event is ready.
|
||||
|
||||
```package-install
|
||||
npm i @llamaindex/workflow-core
|
||||
```
|
||||
You can create a `Workflow` to do anything! Build an agent, a RAG flow, an extraction flow, or anything else you want.
|
||||
|
||||
This contains the core functionality for the workflow system. You can read more about the core concepts in the [workflow-core](/docs/workflows) section.
|
||||
|
||||
In contrast, the `@llamaindex/workflow` package contains more utiltities, such as prebuilt agents.
|
||||
|
||||
```package-install
|
||||
npm i @llamaindex/workflow
|
||||
```
|
||||
|
||||
## Getting Started
|
||||
|
||||
As an illustrative example, let's consider a naive workflow where a joke is generated and then critiqued.
|
||||
|
||||
<include cwd>../../examples/workflow/joke.ts</include>
|
||||
|
||||
There's a few moving pieces here, so let's go through this piece by piece.
|
||||
|
||||
### Defining Workflow Events
|
||||
|
||||
```typescript
|
||||
export class JokeEvent extends WorkflowEvent<{ joke: string }> {}
|
||||
```
|
||||
|
||||
Events are user-defined classes that extend `WorkflowEvent` and contain arbitrary data provided as template argument. In this case, our workflow relies on a single user-defined event, the `JokeEvent` with a `joke` attribute of type `string`.
|
||||
|
||||
### Setting up the Workflow Class
|
||||
|
||||
```typescript
|
||||
const llm = new OpenAI();
|
||||
...
|
||||
const jokeFlow = new Workflow<unknown, string, string>();
|
||||
```
|
||||
|
||||
Our workflow is implemented by initiating the `Workflow` class with three generic types: the context type (unknown), input type (string), and output type (string). The context type is `unknown`, as we're not using a shared context in this example.
|
||||
|
||||
For simplicity, we created an `OpenAI` llm instance that we're using for inference in our workflow.
|
||||
|
||||
### Workflow Entry Points
|
||||
|
||||
```typescript
|
||||
const generateJoke = async (_: unknown, ev: StartEvent<string>) => {
|
||||
const prompt = `Write your best joke about ${ev.data}.`;
|
||||
const response = await llm.complete({ prompt });
|
||||
return new JokeEvent({ joke: response.text });
|
||||
};
|
||||
```
|
||||
|
||||
Here, we come to the entry-point of our workflow. While events are user-defined, there are two special-case events, the `StartEvent` and the `StopEvent`. These events are predefined, but we can specify the payload type using generic types. We're using `StartEvent<string>` to indicate that we're going to send an input of type string.
|
||||
|
||||
To add this step to the workflow, we use the `addStep` method with an object specifying the input and output event types:
|
||||
|
||||
```typescript
|
||||
jokeFlow.addStep(
|
||||
{
|
||||
inputs: [StartEvent<string>],
|
||||
outputs: [JokeEvent],
|
||||
},
|
||||
generateJoke
|
||||
);
|
||||
```
|
||||
|
||||
### Workflow Exit Points
|
||||
|
||||
```typescript
|
||||
const critiqueJoke = async (_: unknown, ev: JokeEvent) => {
|
||||
const prompt = `Give a thorough critique of the following joke: ${ev.data.joke}`;
|
||||
const response = await llm.complete({ prompt });
|
||||
return new StopEvent(response.text);
|
||||
};
|
||||
```
|
||||
|
||||
Here, we have our second and last step in the workflow. We know it's the last step because the special `StopEvent` is returned. When the workflow encounters a returned `StopEvent`, it immediately stops the workflow and returns the result. Note that we're using the generic type `StopEvent<string>` to indicate that we're returning a string.
|
||||
|
||||
Add this step to the workflow:
|
||||
|
||||
```typescript
|
||||
jokeFlow.addStep(
|
||||
{
|
||||
inputs: [JokeEvent],
|
||||
outputs: [StopEvent<string>],
|
||||
},
|
||||
critiqueJoke
|
||||
);
|
||||
```
|
||||
|
||||
### Running the Workflow
|
||||
|
||||
```typescript
|
||||
const result = await jokeFlow.run("pirates");
|
||||
console.log(result.data.result);
|
||||
```
|
||||
|
||||
Lastly, we run the workflow. The `.run()` method is async, so we use await here to wait for the result.
|
||||
|
||||
## Working with Shared Context/State
|
||||
|
||||
Optionally, you can choose to use a shared context between steps by specifying a context type when creating the workflow. Here's an example where multiple steps access a shared state:
|
||||
|
||||
```typescript
|
||||
import { HandlerContext } from "llamaindex";
|
||||
|
||||
type MyContextData = {
|
||||
query: string;
|
||||
intermediateResults: any[];
|
||||
}
|
||||
|
||||
const query = async (context: HandlerContext<MyContextData>, ev: MyEvent) => {
|
||||
// get the query from the context
|
||||
const query = context.data.query;
|
||||
// do something with context and event
|
||||
const val = ...
|
||||
// store in context
|
||||
context.data.intermediateResults.push(val);
|
||||
|
||||
return new StopEvent({ result });
|
||||
};
|
||||
```
|
||||
|
||||
## Waiting for Multiple Events
|
||||
|
||||
The context does more than just hold data, it also provides utilities to buffer and wait for multiple events.
|
||||
|
||||
For example, you might have a step that waits for a query and retrieved nodes before synthesizing a response:
|
||||
|
||||
```typescript
|
||||
const synthesize = async (context: Context, ev1: QueryEvent, ev2: RetrieveEvent) => {
|
||||
const subPrompts = [`Answer this query using the context provided: ${ev1.data.query}`, `Context: ${ev2.data.context}`];
|
||||
const prompt = subPrompts.join("\n");
|
||||
const response = await llm.complete({ prompt });
|
||||
return new StopEvent({ result: response.text });
|
||||
};
|
||||
```
|
||||
|
||||
Passing multiple events, we can buffer and wait for ALL expected events to arrive. The receiving step function will only be called once all events have arrived.
|
||||
|
||||
## Manually Triggering Events
|
||||
|
||||
Normally, events are triggered by returning another event during a step. However, events can also be manually dispatched using the `ctx.sendEvent(event)` method within a workflow.
|
||||
|
||||

title: Memory
|
||||
description: Manage conversation history and context with agents
|
||||
---
|
||||
|
||||
## Concept
|
||||
|
||||
Memory is a core component of agentic systems. It allows you to store and retrieve information from the past.
|
||||
|
||||
In LlamaIndexTS, you can create memory by using the `createMemory` function. This function will return a `Memory` object, which you can then use to store and retrieve information.
|
||||
|
||||
As the agent runs, it will make calls to `add()` to store information, and `get()` to retrieve information.
|
||||
|
||||
## Usage
|
||||
|
||||
A `Memory` object has both short-term memory (i.e. a FIFO queue of messages) and optionally long-term memory (i.e. extracting information over time).
|
||||
|
||||
`get()` always returns all messages stored in the memory. The longer the agent runs, this will exceed the context window of the agent. To avoid this, the agent is using the `getLLM` method to get the last X messages that fit into the context window.
|
||||
|
||||
### Configuring Memory for an Agent
|
||||
|
||||
Here we're creating a memory with a static block (read more about [memory blocks](#long-term-memory)) that contains some information about the user.
|
||||
|
||||
```ts twoslash
|
||||
import { openai } from "@llamaindex/openai";
|
||||
import { agent } from "@llamaindex/workflow";
|
||||
import { createMemory, staticBlock } from "llamaindex";
|
||||
|
||||
const llm = openai({ model: "gpt-4.1-mini" });
|
||||
|
||||
// Create memory with predefined context
|
||||
const memory = createMemory({
|
||||
memoryBlocks: [
|
||||
staticBlock({
|
||||
content:
|
||||
"The user is a software engineer who loves TypeScript and LlamaIndex.",
|
||||
}),
|
||||
],
|
||||
});
|
||||
|
||||
// Create an agent with the memory
|
||||
const workflow = agent({
|
||||
name: "assistant",
|
||||
llm,
|
||||
memory,
|
||||
});
|
||||
|
||||
const result = await workflow.run("What is my name?");
|
||||
console.log("Response:", result.data.result);
|
||||
```
|
||||
|
||||
### Using Vercel format
|
||||
|
||||
You can also put messages in Vercel format directly to the memory:
|
||||
|
||||
```ts
|
||||
await memory.add({
|
||||
id: "1",
|
||||
createdAt: new Date(),
|
||||
role: "user",
|
||||
content: "Hello!",
|
||||
options: {
|
||||
parts: [
|
||||
{
|
||||
type: "file",
|
||||
data: "base64...",
|
||||
mimeType: "image/png",
|
||||
},
|
||||
],
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
If you call `get`, messages are usually retrieved in the LlamaIndexTS format (type `ChatMessage`). If you specify the `type` parameter using `get`, you can return the messages in different formats. E.g.: using `type: "vercel"`, you can return the messages in Vercel format:
|
||||
|
||||
```ts
|
||||
const messages = await memory.get({ type: "vercel" });
|
||||
console.log(messages);
|
||||
```
|
||||
|
||||
## Customizing Memory
|
||||
|
||||
### Short-Term Memory
|
||||
|
||||
The `Memory` object will store all the messages that are added to the `Memory` object. Unless you call `clear()`, no messages are removed from the memory. This is the short-term memory (usually you will store the memory of one user session there) which is augmented by the long-term memory.
|
||||
|
||||
Calling `getLLM` will retrieve messages from long-term memory and ensure that the given `tokenLimit` is not reached. These are the messages that you will sent to the LLM.
|
||||
|
||||
For initialization, you call `createMemory` with the following options:
|
||||
|
||||
- `tokenLimit`: Maximum tokens for memory retrieval using `getLLM` (default: 30000).
|
||||
- `shortTermTokenLimitRatio`: Ratio of tokens for short-term vs long-term memory (default: 0.7)
|
||||
- `customAdapters`: Custom message adapters for different message formats. LlamaIndex (`ChatMessageAdapter`) and Vercel (`VercelMessageAdapter`) are built-in adapters.
|
||||
- `memoryBlocks`: Memory blocks for long-term storage, see [Long-Term Memory](#long-term-memory)
|
||||
|
||||
Example:
|
||||
|
||||
```ts
|
||||
const memory = createMemory({
|
||||
tokenLimit=40000,
|
||||
shortTermTokenLimitRatio=0.5,
|
||||
});
|
||||
```
|
||||
|
||||
### Long-Term Memory
|
||||
|
||||
Long-term memory is represented as `Memory Block` objects. These objects contain information that are from previous user sessions or from the beginning of the current conversation. When memory is retrieved (by calling `getLLM`), the short-term and long-term memories are merged together within the given `tokenLimit`.
|
||||
|
||||
Currently, there are two predefined memory blocks:
|
||||
|
||||
- `staticBlock`: A memory block that stores a static piece of information.
|
||||
- `factExtractionBlock`: A memory block that extracts facts from the chat history.
|
||||
|
||||
This sounds a bit complicated, but it's actually quite simple. Let's look at an example:
|
||||
|
||||
```ts
|
||||
import { createMemory, factExtractionBlock, staticBlock } from "llamaindex";
|
||||
|
||||
const memoryBlocks= [
|
||||
staticBlock({
|
||||
id: "core_info",
|
||||
content: "My name is Logan, and I live in Saskatoon. I work at LlamaIndex.",
|
||||
}),
|
||||
factExtractionBlock({
|
||||
id: "user-extracted_info",
|
||||
priority: 1,
|
||||
llm: llm,
|
||||
maxFacts: 50,
|
||||
}),
|
||||
];
|
||||
```
|
||||
|
||||
Here, we've setup two memory blocks:
|
||||
|
||||
- `core_info`: A static memory block that stores some core information about the user. This information will always be inserted into the memory. The type used is `MessageContent` to support multi-modal content.
|
||||
- `extracted_info`: An extracted memory block that will extract information from the chat history. Here we've passed in the `llm` to use to extract facts from the chat history, and set the `maxFacts` to 50. If the number of extracted facts exceeds this limit, the `maxFacts` will be automatically summarized and reduced to leave room for new information.
|
||||
|
||||
You'll also notice that we've set the `priority` for the `factExtractionBlock` block. This is used to determine the handling when the memory blocks content (i.e. long-term memory) + short-term memory exceeds the token limit on the `Memory` object.
|
||||
|
||||
- `priority=0`: This block will always be kept in memory (`staticBlocks` always have priority 0.)
|
||||
- `priority=1, 2, 3, etc`: This determines the order in which memory blocks are truncated when the memory exceeds the token limit, to help the overall short-term memory + long-term memory content be less than or equal to the `tokenLimit`.
|
||||
|
||||
Now, let's pass these blocks into the `createMemory` function:
|
||||
|
||||
```ts
|
||||
const memory = createMemory({
|
||||
tokenLimit: 40000,
|
||||
memoryBlocks: memoryBlocks,
|
||||
)
|
||||
```
|
||||
|
||||
When memory is retrieved (using `getLLM`), the short-term and long-term memories are merged together. The `Memory` object will ensure that the short-term memory + long-term memory content is less than or equal to the `tokenLimit`. If it is longer, messages are retrieved in the following order:
|
||||
|
||||
1. StaticMemoryBlock (information always included)
|
||||
2. LongTermMemoryBlock (depending on priority)
|
||||
3. ShortTermMemoryBlock
|
||||
4. Transient messages
|
||||
|
||||
The amount of short-term memory included is specified by the `shortTermTokenLimitRatio`. If it's set to `0.7`, 70% of the `tokenLimit` is used for short-term memory (not including the static memory block).
|
||||
|
||||
## Persistence with Snapshots
|
||||
|
||||
Save and restore memory state:
|
||||
|
||||
```ts twoslash
|
||||
import { createMemory, loadMemory } from "llamaindex";
|
||||
|
||||
const memory = createMemory();
|
||||
|
||||
// Add some messages
|
||||
await memory.add({ role: "user", content: "Hello!" });
|
||||
|
||||
// Create snapshot
|
||||
const snapshot = memory.snapshot();
|
||||
|
||||
// Later, restore from the snapshot
|
||||
const restoredMemory = loadMemory(snapshot);
|
||||
```
|
||||

---
|
||||
|
||||
To use Azure OpenAI, you only need to install the `@llamaindex/azure` package:
|
||||
To use Azure OpenAI, you only need to set a few environment variables together with the `OpenAI` class.
|
||||
|
||||
For example:
|
||||
|
||||
## Environment Variables
|
||||
|
||||
```
|
||||
export AZURE_OPENAI_KEY="<YOUR KEY HERE>"
|
||||
export AZURE_OPENAI_ENDPOINT="<YOUR ENDPOINT, see https://learn.microsoft.com/en-us/azure/ai-services/openai/quickstart?tabs=command-line%2Cpython&pivots=rest-api>"
|
||||
export AZURE_OPENAI_DEPLOYMENT="gpt-4" # or some other deployment name
|
||||
```
|
||||
|
||||
## Installation
|
||||
|
||||
```package-install
|
||||
npm i llamaindex @llamaindex/azure
|
||||
npm i llamaindex @llamaindex/openai
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
The class `AzureOpenAI` is used for setting the LLM and `AzureOpenAIEmbedding` is used for setting the embedding model, e.g.:
|
||||
|
||||
```ts
|
||||
import { Settings } from "llamaindex";
|
||||
import { AzureOpenAI, AzureOpenAIEmbedding } from "@llamaindex/azure";
|
||||
import { OpenAI } from "@llamaindex/openai";
|
||||
|
||||
Settings.llm = new AzureOpenAI({
|
||||
apiKey: '[key]',
|
||||
deployment: '[model]',
|
||||
apiVersion: '[version]',
|
||||
endpoint: `https://[deployment].openai.azure.com/`,
|
||||
});
|
||||
Settings.embedModel = new AzureOpenAIEmbedding({
|
||||
apiKey: '[key]',
|
||||
deployment: '[embedding-model]',
|
||||
apiVersion: '[version]',
|
||||
endpoint: `https://[deployment].openai.azure.com/`,
|
||||
Settings.llm = new OpenAI({ model: "gpt-4", temperature: 0 });
|
||||
```
|
||||
|
||||
## Load and index documents
|
||||
|
||||
For this example, we will use a single document. In a real-world scenario, you would have multiple documents to index.
|
||||
|
||||
```ts
|
||||
const document = new Document({ text: essay, id_: "essay" });
|
||||
|
||||
const index = await VectorStoreIndex.fromDocuments([document]);
|
||||
```
|
||||
|
||||
## Query
|
||||
|
||||
```ts
|
||||
const queryEngine = index.asQueryEngine();
|
||||
|
||||
const query = "What is the meaning of life?";
|
||||
|
||||
const results = await queryEngine.query({
|
||||
query,
|
||||
});
|
||||
```
|
||||
|
||||
Instead of explicitly setting the API key, deployment, version, and endpoint in the constructor, you can use the following environment variables: `AZURE_OPENAI_DEPLOYMENT` for the model deployment name, `AZURE_OPENAI_KEY` for your API key, `AZURE_OPENAI_ENDPOINT` for your Azure endpoint URL, and `AZURE_OPENAI_API_VERSION` for the API version.

model: GEMINI_MODEL.GEMINI_PRO,
|
||||
});
|
||||
```
|
||||
|
||||
## Usage with Proxy
|
||||
|
||||
```ts
|
||||
import { Gemini, GEMINI_MODEL } from "@llamaindex/google";
|
||||
import { Settings } from "llamaindex";
|
||||
|
||||
Settings.llm = new Gemini({
|
||||
model: GEMINI_MODEL.GEMINI_PRO,
|
||||
requestOptions: {
|
||||
baseUrl: <YOUR_PROXY_URL> // optional, but useful for custom endpoints
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Usage with Vertex AI
|
||||
|
||||
To use Gemini via Vertex AI, you can specify the vertex configuration:
|
||||
To use Gemini via Vertex AI you can use `GeminiVertexSession`.
|
||||
|
||||
GeminiVertexSession accepts the env variables: `GOOGLE_VERTEX_LOCATION` and `GOOGLE_VERTEX_PROJECT`
|
||||
|
||||
```ts
|
||||
import { gemini, GEMINI_MODEL } from "@llamaindex/google";
|
||||
import { Gemini, GEMINI_MODEL, GeminiVertexSession } from "@llamaindex/google";
|
||||
|
||||
const llm = gemini({
|
||||
model: GEMINI_MODEL.GEMINI_2_0_FLASH,
|
||||
vertex: {
|
||||
project: "your-cloud-project", // required for Vertex AI
|
||||
location: "us-central1", // required for Vertex AI
|
||||
},
|
||||
const gemini = new Gemini({
|
||||
model: GEMINI_MODEL.GEMINI_PRO,
|
||||
session: new GeminiVertexSession({
|
||||
location: "us-central1", // optional if provided by GOOGLE_VERTEX_LOCATION env variable
|
||||
project: "project1", // optional if provided by GOOGLE_VERTEX_PROJECT env variable
|
||||
googleAuthOptions: {...}, // optional, but useful for production. It accepts all values from `GoogleAuthOptions`
|
||||
}),
|
||||
});
|
||||
```
|
||||
|
||||
[GoogleAuthOptions](https://github.com/googleapis/google-auth-library-nodejs/blob/main/src/auth/googleauth.ts)
|
||||
|
||||
To authenticate for local development:
|
||||
|
||||
```bash
|
||||
npm i @google-cloud/vertexai
|
||||
gcloud auth application-default login
|
||||
```
|
||||
|
||||
To authenticate for production you'll have to use a [service account](https://cloud.google.com/docs/authentication/). `googleAuthOptions` has `credentials` which might be useful for you.
|
||||
|
||||
## Multimodal Usage
|
||||
|
||||
Gemini supports multimodal inputs including text, images, audio, and video:
|
||||
|
||||
```ts
|
||||
import { gemini, GEMINI_MODEL } from "@llamaindex/google";
|
||||
import fs from "fs";
|
||||
|
||||
const llm = gemini({ model: GEMINI_MODEL.GEMINI_2_0_FLASH });
|
||||
|
||||
const result = await llm.chat({
|
||||
messages: [
|
||||
{
|
||||
role: "user",
|
||||
content: [
|
||||
{
|
||||
type: "text",
|
||||
text: "What's in this image?",
|
||||
},
|
||||
{
|
||||
type: "image",
|
||||
data: fs.readFileSync("./image.jpg").toString("base64"),
|
||||
mimeType: "image/jpeg",
|
||||
},
|
||||
],
|
||||
},
|
||||
],
|
||||
});
|
||||
```
|
||||
|
||||
## Tool Calling
|
||||
|
||||
Gemini supports function calling with tools:
|
||||
|
||||
```ts
|
||||
import { gemini, GEMINI_MODEL } from "@llamaindex/google";
|
||||
import { tool } from "llamaindex";
|
||||
import { z } from "zod";
|
||||
|
||||
const llm = gemini({ model: GEMINI_MODEL.GEMINI_2_0_FLASH });
|
||||
|
||||
const result = await llm.chat({
|
||||
messages: [
|
||||
{
|
||||
content: "What's the weather in Tokyo?",
|
||||
role: "user",
|
||||
},
|
||||
],
|
||||
tools: [
|
||||
tool({
|
||||
name: "weather",
|
||||
description: "Get the weather",
|
||||
parameters: z.object({
|
||||
location: z.string().describe("The location to get the weather for"),
|
||||
}),
|
||||
execute: ({ location }) => {
|
||||
return `The weather in ${location} is sunny and hot`;
|
||||
},
|
||||
}),
|
||||
],
|
||||
});
|
||||
```
|
||||
|
||||
## Live API (Real-time Conversations)
|
||||
|
||||
For real-time audio/video conversations using [Gemini Live API](https://ai.google.dev/gemini-api/docs/live).
|
||||
|
||||
The Live API is running directly in the frontend. That's why you have to generate an ephemeral key first on the server side and pass it to the frontend.
|
||||
|
||||
To use the Live API, make sure to pass `apiVersion: "v1alpha"` to the `httpOptions`.
|
||||
|
||||
```ts
|
||||
import { gemini, GEMINI_MODEL } from "@llamaindex/google";
|
||||
|
||||
// Server-side: Generate ephemeral key
|
||||
const serverLlm = gemini({
|
||||
model: GEMINI_MODEL.GEMINI_2_0_FLASH_LIVE,
|
||||
httpOptions: { apiVersion: "v1alpha" },
|
||||
});
|
||||
const ephemeralKey = await serverLlm.live.getEphemeralKey();
|
||||
|
||||
// Client-side: Use ephemeral key for Live API
|
||||
const llm = gemini({
|
||||
apiKey: ephemeralKey,
|
||||
model: GEMINI_MODEL.GEMINI_2_0_FLASH_LIVE,
|
||||
voiceName: "Zephyr",
|
||||
httpOptions: { apiVersion: "v1alpha" },
|
||||
});
|
||||
|
||||
const session = await llm.live.connect();

||||
```

# OpenAI Live LLM
|
||||
|
||||
The OpenAI Live LLM integration in LlamaIndex provides real-time chat capabilities with support for audio streaming and tool calling.
|
||||
|
||||
## Basic Usage
|
||||
|
||||
```typescript
|
||||
import { openai } from "@llamaindex/openai";
|
||||
import { tool, ModalityType } from "llamaindex";
|
||||
|
||||
// Get the ephimeral key on the server
|
||||
const serverllm = openai({
|
||||
apiKey: "your-api-key",
|
||||
model: "gpt-4o-realtime-preview-2025-06-03",
|
||||
});
|
||||
|
||||
// Get an ephemeral key
|
||||
// Usually this code is run on the server and the ephemeral key is passed to the
|
||||
// client - the ephemeral key can be securely used on the client side
|
||||
const ephemeralKey = await serverllm.live.getEphemeralKey();
|
||||
|
||||
// Create a client-side LLM instance with the ephemeral key
|
||||
const llm = openai({
|
||||
apiKey: ephemeralKey,
|
||||
model: "gpt-4o-realtime-preview-2025-06-03"
|
||||
});
|
||||
|
||||
// Create a live sessionimport { tool } from "llamaindex";
|
||||
const session = await llm.live.connect({
|
||||
systemInstruction: "You are a helpful assistant.",
|
||||
});
|
||||
|
||||
// Send a message
|
||||
session.sendMessage({
|
||||
content: "Hello!",
|
||||
role: "user",
|
||||
});
|
||||
```
|
||||
|
||||
## Tool Integration
|
||||
|
||||
Tools are handled server-side, making it simple to pass them to the live session:
|
||||
|
||||
```typescript
|
||||
// Define your tools
|
||||
const weatherTool = tool({
|
||||
name: "weather",
|
||||
description: "Get the weather for a location",
|
||||
parameters: z.object({
|
||||
location: z.string().describe("The location to get weather for"),
|
||||
}),
|
||||
execute: async ({ location }) => {
|
||||
return `The weather in ${location} is sunny`;
|
||||
},
|
||||
});
|
||||
|
||||
// Create session with tools
|
||||
const session = await llm.live.connect({
|
||||
systemInstruction: "You are a helpful assistant.",
|
||||
tools: [weatherTool],
|
||||
});
|
||||
```
|
||||
|
||||
## Audio Support
|
||||
|
||||
For audio capabilities:
|
||||
|
||||
```typescript
|
||||
// Get microphone access
|
||||
const userStream = await navigator.mediaDevices.getUserMedia({
|
||||
audio: true,
|
||||
});
|
||||
|
||||
// Create session with audio
|
||||
const session = await llm.live.connect({
|
||||
audioConfig: {
|
||||
stream: userStream,
|
||||
onTrack: (remoteStream) => {
|
||||
// Handle incoming audio
|
||||
audioElement.srcObject = remoteStream;
|
||||
},
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
## Event Handling
|
||||
|
||||
Listen to events from the session:
|
||||
|
||||
```typescript
|
||||
for await (const event of session.streamEvents()) {
|
||||
if (liveEvents.open.include(event)) {
|
||||
// Connection established
|
||||
console.log("Connected!");
|
||||
} else if (liveEvents.text.include(event)) {
|
||||
// Received text response
|
||||
console.log("Assistant:", event.text);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Capabilities
|
||||
|
||||
The OpenAI Live LLM supports:
|
||||
|
||||
- Real-time text chat
|
||||
- Audio streaming (if configured)
|
||||
- Tool calling (server-side execution)
|
||||
- Ephemeral key generation for secure sessions
|
||||
|
||||
## API Reference
|
||||
|
||||
### LiveLLM Methods
|
||||
// Get an ephemeral key
|
||||
// Usually this code is run on the server and the ephemeral key is passed to the
|
||||
// client - the ephemeral key can be securely used on the client side
|
||||
|
||||
#### `connect(config?: LiveConnectConfig)`
|
||||
|
||||
Creates a new live session.
|
||||
|
||||
```typescript
|
||||
interface LiveConnectConfig {
|
||||
systemInstruction?: string;
|
||||
tools?: BaseTool[];
|
||||
audioConfig?: AudioConfig;
|
||||
responseModality?: ModalityType[];
|
||||
}
|
||||
```
|
||||
|
||||
#### `getEphemeralKey()`
|
||||
|
||||
Gets a temporary key for the session.
|
||||
|
||||
### LiveLLMSession Methods
|
||||
|
||||
#### `sendMessage(message: ChatMessage)`
|
||||
|
||||
Sends a message to the assistant.
|
||||
|
||||
```typescript
|
||||
interface ChatMessage {
|
||||
content: string | MessageContentDetail[];
|
||||
role: "user" | "assistant";
|
||||
}
|
||||
```
|
||||
|
||||
#### `disconnect()`
|
||||
|
||||
Closes the session and cleans up resources.
|
||||
|
||||
## Error Handling
|
||||
|
||||
```typescript
|
||||
try {
|
||||
const session = await llm.live.connect();
|
||||
} catch (error) {
|
||||
if (error instanceof Error) {
|
||||
console.error("Connection failed:", error.message);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Tool Definition**
|
||||
|
||||
- Keep tool implementations server-side
|
||||
- Use clear descriptions for tools
|
||||
- Handle tool errors gracefully
|
||||
|
||||
2. **Session Management**
|
||||
|
||||
- Always disconnect sessions when done
|
||||
- Clean up audio resources
|
||||
- Handle reconnection scenarios
|
||||
|
||||
3. **Security**
|
||||
- Use ephemeral keys for sessions
|
||||
- Validate tool inputs
|
||||
- Secure API key handling

title: Using API Route

description: Chat interface for your LlamaIndexTS application using API Route
|

---
|
||||
|
||||
Using [chat-ui](https://github.com/run-llama/chat-ui), it's easy to add a chat interface to your LlamaIndexTS application.
|
||||
You just need to create an API route that provides an `api/chat` endpoint and a chat component to consume the API.
|
||||
|
||||
## API route
|
||||
|
||||
As an example, this is an API route for the Next.js App Router. Copy the following code into your `app/api/chat/route.ts` file to get started:
|
||||
|
||||
```json doc-gen:file
|
||||
{
|
||||
"file": "./src/app/api/chat/route.ts",
|
||||
"codeblock": true
|
||||
}
|
||||
```
|
||||
|
||||
## Chat UI
|
||||
|
||||
This is the simplest way to add a chat interface to your application. Copy the following code into your application to consume the API:
|
||||
|
||||
```json doc-gen:file
|
||||
{
|
||||
"file": "./src/components/demo/chat/api/demo.tsx",
|
||||
"codeblock": true
|
||||
}
|
||||
```
|
||||
|
||||
## Try it out ⬇️
|
||||
|
||||
Combining both, you're getting a fully functional chat interface:
|
||||
|
||||
<ChatDemo />
|
||||
|
||||
|
||||
## Next Steps
|
||||
|
||||
The steps above are the bare minimum to get a chat interface working. From here, you can go two ways:
|
||||
|
||||
1. Use [create-llama](https://github.com/run-llama/create-llama) to scaffold a new LlamaIndexTS project including complex API routes and chat interfaces or

2. Learn more about [chat-ui](https://github.com/run-llama/chat-ui) and [LlamaIndexTS](https://github.com/run-llama/llamaindex-ts) to customize the chat interface and API routes to your needs.

npm i @llamaindex/server
|
||||
```
|
||||
|
||||
## Quick Start
|
||||
|
||||
Check the latest information on the NPM package page: https://www.npmjs.com/package/@llamaindex/server
|
||||
Create index.ts file and add the following code:
|
||||
|
||||
```ts
|
||||
import { LlamaIndexServer } from "@llamaindex/server";
|
||||
import { wiki } from "@llamaindex/tools"; // or any other tool
|
||||
|
||||
const createWorkflow = () => agent({ tools: [wiki()] })
|
||||
|
||||
new LlamaIndexServer({
|
||||
workflow: createWorkflow,
|
||||
uiConfig: {
|
||||
appTitle: "LlamaIndex App",
|
||||
starterQuestions: ["Who is the first president of the United States?"],
|
||||
},
|
||||
}).start();
|
||||
```
|
||||
|
||||
## Running the Server
|
||||
|
||||
In the same directory as `index.ts`, run the following command to start the server:
|
||||
|
||||
```bash
|
||||
tsx index.ts
|
||||
```
|
||||
The server will start at `http://localhost:3000`
|
||||
|
||||
You can also make a request to the server:
|
||||
|
||||
```bash
|
||||
curl -X POST "http://localhost:3000/api/chat" -H "Content-Type: application/json" -d '{"message": "Who is the first president of the United States?"}'
|
||||
```
|
||||
|
||||
## Configuration Options
|
||||
|
||||
The LlamaIndexServer accepts the following configuration
|
||||
|
||||
- `workflow`: A callable function that creates a workflow instance for each request
|
||||
- `uiConfig`: An object to configure the chat UI containing the following properties:
|
||||
- `appTitle`: The title of the application (default: `"LlamaIndex App"`)
|
||||
- `starterQuestions`: List of starter questions for the chat UI (default: `[]`)
|
||||
- `componentsDir`: The directory for custom UI components rendering events emitted by the workflow. The default is undefined, which does not render custom UI components.
|
||||
- `llamaCloudIndexSelector`: Whether to show the LlamaCloud index selector in the chat UI (requires `LLAMA_CLOUD_API_KEY` to be set in the environment variables) (default: `false`)
|
||||
|
||||
LlamaIndexServer accepts all the configuration options from Nextjs Custom Server such as `port`, `hostname`, `dev`, etc.
|
||||
See all Nextjs Custom Server options [here](https://nextjs.org/docs/app/building-your-application/configuring/custom-server).
|
||||
|
||||
## Default Endpoints and Features
|
||||
|
||||
### Chat Endpoint
|
||||
|
||||
The server includes a default chat endpoint at `/api/chat` for handling chat interactions.
|
||||
|
||||
### Chat UI
|
||||
|
||||
The server always provides a chat interface at the root path (`/`) with:
|
||||
|
||||
- Configurable starter questions
|
||||
- Real-time chat interface
|
||||
- API endpoint integration
|
||||
|
||||
### Static File Serving
|
||||
|
||||
- The server automatically mounts the `data` and `output` folders at `{server_url}{api_prefix}/files/data` (default: `/api/files/data`) and `{server_url}{api_prefix}/files/output` (default: `/api/files/output`) respectively.
|
||||
- Your workflows can use both folders to store and access files. As a convention, the `data` folder is used for documents that are ingested and the `output` folder is used for documents that are generated by the workflow.
|
||||
|
||||
|
||||
## Custom UI Components
|
||||
|
||||
The LlamaIndex server provides support for rendering workflow events using custom UI components, allowing you to extend and customize the chat interface.
|
||||
|
||||
### Overview
|
||||
|
||||
Custom UI components are a powerful feature that enables you to:
|
||||
|
||||
- Add custom interface elements to the chat UI using React JSX or TSX files
|
||||
- Extend the default chat interface functionality
|
||||
- Create specialized visualizations or interactions
|
||||
|
||||
### Configuration
|
||||
|
||||
Your workflow must emit events that fit this structure, allowing the LlamaIndex server to display the right UI components based on the event type.
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "<event_name>",
|
||||
"data": <data model>
|
||||
}
|
||||
```
|
||||
|
||||
### Server Setup
|
||||
|
||||
1. Initialize the LlamaIndex server with a component directory:
|
||||
|
||||
```ts
|
||||
new LlamaIndexServer({
|
||||
workflow: createWorkflow,
|
||||
uiConfig: {
|
||||
appTitle: "LlamaIndex App",
|
||||
componentsDir: "components",
|
||||
},
|
||||
}).start();
|
||||
```
|
||||
|
||||
2. Add the custom component code to the directory following the naming pattern:
|
||||
|
||||
- File Extension: `.jsx` and `.tsx` for React components
|
||||
- File Name: Should match the event type from your workflow (e.g., `deep_research_event.jsx` for handling `deep_research_event` type that you defined in your workflow). If there are TSX and JSX files with the same name, the TSX file will be used.
|
||||
- Component Name: Export a default React component named `Component` that receives props from the event data
|
||||
|
||||
Example component structure:
|
||||
|
||||
```jsx
|
||||
function Component({ events }) {
|
||||
// Your component logic here
|
||||
return (
|
||||
// Your UI code here
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. Always provide a workflow factory that creates fresh workflow instances
|
||||
2. Use environment variables for sensitive configuration
|
||||
3. Use starter questions to guide users in the chat UI
|
||||

title: Using Next.js RSC
|

description: Chat interface for your LlamaIndexTS application using Next.js RSC
|
||||
---
|
||||
|
||||
Using [chat-ui](https://github.com/run-llama/chat-ui), it's easy to add a chat interface to your LlamaIndexTS application using [Next.js RSC](https://nextjs.org/docs/app/building-your-application/rendering/server-components) and [Vercel AI RSC](https://sdk.vercel.ai/docs/ai-sdk-rsc/overview).
|
||||
|
||||
With RSC, the chat messages are not returned as JSON from the server (like when using an [API route](/docs/llamaindex/modules/ui/chat)), instead the chat message components are rendered on the server side.
|
||||
This is for example useful for rendering a whole chat history on the server before sending it to the client. [Check here](https://sdk.vercel.ai/docs/getting-started/navigating-the-library#when-to-use-ai-sdk-rsc), for a discussion of when to use use RSC.
|
||||
|
||||
For implementing a chat interface with RSC, you need to create an AI action and then connect the chat interface to use it.
|
||||
|
||||
## Create an AI action
|
||||
|
||||
First, define an [AI context provider](https://sdk.vercel.ai/examples/rsc/state-management/ai-ui-states) with a chat server action:
|
||||
|
||||
```json doc-gen:file
|
||||
{
|
||||
"file": "./src/components/demo/chat/rsc/ai-action.tsx",
|
||||
"codeblock": true
|
||||
}
|
||||
```
|
||||
|
||||
The chat server action is using LlamaIndexTS to generate a response based on the chat history and the user input.
|
||||
|
||||
## Create the chat UI
|
||||
|
||||
The entrypoint of our application initializes the AI provider for the application and adds a `ChatSection` component:
|
||||
|
||||
```json doc-gen:file
|
||||
{
|
||||
"file": "./src/components/demo/chat/rsc/demo.tsx",
|
||||
"codeblock": true
|
||||
}
|
||||
```
|
||||
|
||||
The `ChatSection` component is created by using chat components from @llamaindex/chat-ui:
|
||||
|
||||
```json doc-gen:file
|
||||
{
|
||||
"file": "./src/components/demo/chat/rsc/chat-section.tsx",
|
||||
"codeblock": true
|
||||
}
|
||||
```
|
||||
|
||||
It is using a `useChatRSC` hook to conntect the chat interface to the `chat` AI action that we defined earlier:
|
||||
|
||||
```json doc-gen:file
|
||||
{
|
||||
"file": "./src/components/demo/chat/rsc/use-chat-rsc.tsx",
|
||||
"codeblock": true
|
||||
}
|
||||
```
|
||||
|
||||
## Try RSC Chat ⬇️
|
||||
|
||||
<ChatDemoRSC />
|
||||
|
||||
## Next Steps
|
||||
|
||||
The steps above are the bare minimum to get a chat interface working with RSC. From here, you can go two ways:
|
||||
|
||||
1. Use our [full-stack RSC example](https://github.com/run-llama/nextjs-rsc) based on [create-llama](https://github.com/run-llama/create-llama) to get started quickly with a fully working chat interface or
|
||||
2. Learn more about [AI RSC](https://sdk.vercel.ai/examples/rsc), [chat-ui](https://github.com/run-llama/chat-ui) and [LlamaIndexTS](https://github.com/run-llama/llamaindex-ts) to customize the chat interface and AI actions to your needs.

Before LlamaIndex can send a query to the LLM, it needs to find the most relevant chunks to send. That's the purpose of a `Retriever`. We're going to get `VectorStoreIndex` to act as a retriever for us

Workflows allow you to work with different event types and compose them in powerful ways:
|
||||
|
||||
### Multiple Event Types
|
||||
|
||||
You can define multiple event types for different kinds of data flowing through your workflow:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent } from "llamaindex";
|
||||
|
||||
// Define different event types
|
||||
const textEvent = workflowEvent<string>();
|
||||
const numberEvent = workflowEvent<number>();
|
||||
const booleanEvent = workflowEvent<boolean>();
|
||||
const complexEvent = workflowEvent<{ id: string; value: number }>();
|
||||
|
||||
// Create a workflow that can process different event types
|
||||
const workflow = createWorkflow();
|
||||
|
||||
// Handle text events
|
||||
workflow.handle([textEvent], (event) => {
|
||||
console.log(`Processing text: ${event.data}`);
|
||||
return numberEvent.with(event.data.length);
|
||||
});
|
||||
|
||||
// Handle number events
|
||||
workflow.handle([numberEvent], (event) => {
|
||||
const isEven = event.data % 2 === 0;
|
||||
console.log(`Number ${event.data} is ${isEven ? 'even' : 'odd'}`);
|
||||
return booleanEvent.with(isEven);
|
||||
});
|
||||
|
||||
// Handle boolean events
|
||||
workflow.handle([booleanEvent], (event) => {
|
||||
return complexEvent.with({
|
||||
id: crypto.randomUUID(),
|
||||
value: event.data ? 100 : 0
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Event Branching and Merging
|
||||
|
||||
You can create complex event flows with branching and merging patterns:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent, until, collect } from "llamaindex";
|
||||
|
||||
// Define events for a data processing pipeline
|
||||
const inputEvent = workflowEvent<string>();
|
||||
const validateEvent = workflowEvent<string>();
|
||||
const processEvent = workflowEvent<string>();
|
||||
const errorEvent = workflowEvent<Error>();
|
||||
const resultEvent = workflowEvent<string>();
|
||||
const completeEvent = workflowEvent<string[]>();
|
||||
|
||||
// Create workflow
|
||||
const workflow = createWorkflow();
|
||||
|
||||
// Branch based on input validation
|
||||
workflow.handle([inputEvent], (event) => {
|
||||
if (event.data && event.data.trim().length > 0) {
|
||||
return validateEvent.with(event.data.trim());
|
||||
} else {
|
||||
return errorEvent.with(new Error("Empty input"));
|
||||
}
|
||||
});
|
||||
|
||||
// Process valid inputs
|
||||
workflow.handle([validateEvent], (event) => {
|
||||
return processEvent.with(event.data.toUpperCase());
|
||||
});
|
||||
|
||||
// Handle processing
|
||||
workflow.handle([processEvent], (event) => {
|
||||
return resultEvent.with(`Processed: ${event.data}`);
|
||||
});
|
||||
|
||||
// Handle errors
|
||||
workflow.handle([errorEvent], (event) => {
|
||||
return resultEvent.with(`Error: ${event.data.message}`);
|
||||
});
|
||||
|
||||
// Merge results: collect multiple results into a single completion event
|
||||
workflow.handle([inputEvent], (start) => {
|
||||
const { sendEvent, stream } = getContext();
|
||||
|
||||
// Process all inputs
|
||||
const inputs = start.data.split(',').map(s => s.trim());
|
||||
inputs.forEach(input => sendEvent(inputEvent.with(input)));
|
||||
|
||||
// Collect all results
|
||||
const results = await collect(
|
||||
until(stream, result => resultEvent.include(result))
|
||||
.filter(ev => resultEvent.include(ev))
|
||||
.take(inputs.length)
|
||||
);
|
||||
|
||||
return completeEvent.with(results.map(r => r.data));
|
||||
});
|
||||
```
|
||||
|
||||
## Event Filtering and Transformation
|
||||
|
||||
You can filter and transform events to build sophisticated data processing pipelines:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent } from "llamaindex";
|
||||
|
||||
// Define events
|
||||
const dataEvent = workflowEvent<number>();
|
||||
const evenEvent = workflowEvent<number>();
|
||||
const oddEvent = workflowEvent<number>();
|
||||
const transformedEvent = workflowEvent<string>();
|
||||
const resultEvent = workflowEvent<string[]>();
|
||||
|
||||
// Create workflow
|
||||
const workflow = createWorkflow();
|
||||
|
||||
// Filter even numbers
|
||||
workflow.handle([dataEvent], (event) => {
|
||||
if (event.data % 2 === 0) {
|
||||
return evenEvent.with(event.data);
|
||||
} else {
|
||||
return oddEvent.with(event.data);
|
||||
}
|
||||
});
|
||||
|
||||
// Transform even numbers
|
||||
workflow.handle([evenEvent], (event) => {
|
||||
return transformedEvent.with(`Even: ${event.data}`);
|
||||
});
|
||||
|
||||
// Transform odd numbers
|
||||
workflow.handle([oddEvent], (event) => {
|
||||
return transformedEvent.with(`Odd: ${event.data}`);
|
||||
});
|
||||
|
||||
// Collect and organize results
|
||||
workflow.handle([dataEvent], (start) => {
|
||||
const { sendEvent, stream } = getContext();
|
||||
|
||||
// Generate a sequence of numbers
|
||||
for (let i = 1; i <= 10; i++) {
|
||||
sendEvent(dataEvent.with(i));
|
||||
}
|
||||
|
||||
// Collect transformed events
|
||||
const results = await collect(
|
||||
until(stream)
|
||||
.filter(ev => transformedEvent.include(ev))
|
||||
.take(10)
|
||||
);
|
||||
|
||||
return resultEvent.with(results.map(r => r.data));
|
||||
});
|
||||
```
|
||||
|
||||
## Working with `withTraceEvents` Middleware
|
||||
|
||||
The `withTraceEvents` middleware adds powerful tracing capabilities to your workflows:
|
||||
|
||||
```ts
|
||||
import {
|
||||
createWorkflow,
|
||||
workflowEvent,
|
||||
withTraceEvents,
|
||||
runOnce,
|
||||
createHandlerDecorator
|
||||
} from "llamaindex";
|
||||
|
||||
// Define events
|
||||
const startEvent = workflowEvent<string>();
|
||||
const processEvent = workflowEvent<string>();
|
||||
const resultEvent = workflowEvent<string>();
|
||||
|
||||
// Create workflow with tracing
|
||||
const workflow = withTraceEvents(createWorkflow());
|
||||
|
||||
// Create a custom handler decorator that logs execution time
|
||||
const measureTime = createHandlerDecorator({
|
||||
debugLabel: "measureTime",
|
||||
getInitialValue: () => performance.now(),
|
||||
onBeforeHandler: (handler, context, startTime) => {
|
||||
console.log(`Starting handler execution at ${new Date().toISOString()}`);
|
||||
return handler;
|
||||
},
|
||||
onAfterHandler: (result, context, startTime) => {
|
||||
const duration = performance.now() - startTime;
|
||||
console.log(`Handler executed in ${duration.toFixed(2)}ms`);
|
||||
return startTime; // Return the initial value for next execution
|
||||
}
|
||||
});
|
||||
|
||||
// Run a specific handler only once
|
||||
workflow.handle(
|
||||
[startEvent],
|
||||
runOnce((event) => {
|
||||
console.log("This handler will only run once per workflow context");
|
||||
return processEvent.with(event.data);
|
||||
})
|
||||
);
|
||||
|
||||
// Measure the execution time of this handler
|
||||
workflow.handle(
|
||||
[processEvent],
|
||||
measureTime((event) => {
|
||||
// Simulate processing time
|
||||
const start = Date.now();
|
||||
while (Date.now() - start < 100) {
|
||||
// Busy wait for 100ms
|
||||
}
|
||||
return resultEvent.with(`Processed: ${event.data}`);
|
||||
})
|
||||
);
|
||||
```
|
||||
|
||||
### Debugging with Substreams
|
||||
|
||||
You can use the `substream` feature to debug specific event flows:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent, withTraceEvents } from "llamaindex";
|
||||
|
||||
// Define events
|
||||
const queryEvent = workflowEvent<string>();
|
||||
const fetchEvent = workflowEvent<string>();
|
||||
const resultEvent = workflowEvent<string>();
|
||||
|
||||
// Create workflow with tracing
|
||||
const workflow = withTraceEvents(createWorkflow());
|
||||
|
||||
// Query handler
|
||||
workflow.handle([queryEvent], (event) => {
|
||||
const { sendEvent, stream } = getContext();
|
||||
|
||||
// Create a specific fetch event for this query
|
||||
const fetchInstance = fetchEvent.with(event.data);
|
||||
sendEvent(fetchInstance);
|
||||
|
||||
// Create a substream to only track events related to this fetch
|
||||
const substream = workflow.substream(fetchInstance, stream);
|
||||
|
||||
// Listen for results in the substream
|
||||
(async () => {
|
||||
for await (const event of substream) {
|
||||
console.log(`Event in substream: ${event.type}`);
|
||||
}
|
||||
})();
|
||||
|
||||
return resultEvent.with(`Querying: ${event.data}`);
|
||||
});
|
||||
|
||||
// Fetch handler
|
||||
workflow.handle([fetchEvent], (event) => {
|
||||
console.log(`Fetching data for: ${event.data}`);
|
||||
// Actual fetch logic would go here
|
||||
return resultEvent.with(`Results for: ${event.data}`);
|
||||
});
|
||||
```
|
||||
|
||||
## Advanced Validation and Type Safety
|
||||
|
||||
The `withValidation` middleware ensures your workflow connections are both type-safe and runtime-safe:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent, withValidation } from "llamaindex";
|
||||
|
||||
// Define events with explicit types
|
||||
const inputEvent = workflowEvent<string, "input">();
|
||||
const validateEvent = workflowEvent<string, "validate">();
|
||||
const processEvent = workflowEvent<string, "process">();
|
||||
const resultEvent = workflowEvent<string, "result">();
|
||||
const errorEvent = workflowEvent<Error, "error">({
|
||||
debugLabel: "errorEvent" // Add debug labels for better error messages
|
||||
});
|
||||
|
||||
// Define the allowed event flow paths
|
||||
const workflow = withValidation(
|
||||
createWorkflow(),
|
||||
[
|
||||
[[inputEvent], [validateEvent, errorEvent]], // inputEvent can lead to validateEvent or errorEvent
|
||||
[[validateEvent], [processEvent, errorEvent]], // validateEvent can lead to processEvent or errorEvent
|
||||
[[processEvent], [resultEvent, errorEvent]], // processEvent can lead to resultEvent or errorEvent
|
||||
[[errorEvent], [resultEvent]] // errorEvent can lead to resultEvent
|
||||
]
|
||||
);
|
||||
|
||||
// Now use strictHandle to get compile-time validation
|
||||
workflow.strictHandle([inputEvent], (sendEvent, event) => {
|
||||
try {
|
||||
if (!event.data || event.data.trim().length === 0) {
|
||||
throw new Error("Empty input");
|
||||
}
|
||||
// This is allowed by our validation rules
|
||||
sendEvent(validateEvent.with(event.data.trim()));
|
||||
|
||||
// This would cause a compile-time error:
|
||||
// sendEvent(resultEvent.with("Result")); // ❌ Not allowed by validation rules
|
||||
} catch (err) {
|
||||
// This is allowed by our validation rules
|
||||
sendEvent(errorEvent.with(err instanceof Error ? err : new Error(String(err))));
|
||||
}
|
||||
});
|
||||
|
||||
// The rest of the workflow with strict validation
|
||||
workflow.strictHandle([validateEvent], (sendEvent, event) => {
|
||||
// Validation logic here
|
||||
sendEvent(processEvent.with(event.data));
|
||||
});
|
||||
|
||||
workflow.strictHandle([processEvent], (sendEvent, event) => {
|
||||
// Processing logic here
|
||||
sendEvent(resultEvent.with(`Processed: ${event.data}`));
|
||||
});
|
||||
|
||||
workflow.strictHandle([errorEvent], (sendEvent, event) => {
|
||||
// Error handling logic here
|
||||
sendEvent(resultEvent.with(`Error handled: ${event.data.message}`));
|
||||
});
|
||||
```
|
||||
|
||||
## Creating Custom Middleware
|
||||
|
||||
You can create your own middleware to extend the workflow capabilities:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent } from "llamaindex";
|
||||
|
||||
// Create a logging middleware
|
||||
function withLogging(workflow) {
|
||||
const originalHandle = workflow.handle;
|
||||
|
||||
workflow.handle = function(eventTypes, handler) {
|
||||
return originalHandle.call(workflow, eventTypes, async function(...args) {
|
||||
const eventType = eventTypes.map(e => e.name || 'AnonymousEvent').join(',');
|
||||
console.log(`[${new Date().toISOString()}] Handling ${eventType}`);
|
||||
|
||||
try {
|
||||
const result = await handler(...args);
|
||||
console.log(`[${new Date().toISOString()}] Completed ${eventType}`);
|
||||
return result;
|
||||
} catch (error) {
|
||||
console.error(`[${new Date().toISOString()}] Error in ${eventType}:`, error);
|
||||
throw error;
|
||||
}
|
||||
});
|
||||
};
|
||||
|
||||
return workflow;
|
||||
}
|
||||
|
||||
// Create a retry middleware
|
||||
function withRetry(maxRetries = 3, workflow) {
|
||||
const originalHandle = workflow.handle;
|
||||
|
||||
workflow.handle = function(eventTypes, handler) {
|
||||
return originalHandle.call(workflow, eventTypes, async function(...args) {
|
||||
let lastError;
|
||||
|
||||
for (let attempt = 1; attempt <= maxRetries; attempt++) {
|
||||
try {
|
||||
return await handler(...args);
|
||||
} catch (error) {
|
||||
lastError = error;
|
||||
console.warn(`Attempt ${attempt}/${maxRetries} failed:`, error);
|
||||
|
||||
if (attempt < maxRetries) {
|
||||
// Exponential backoff
|
||||
await new Promise(resolve =>
|
||||
setTimeout(resolve, Math.pow(2, attempt - 1) * 100)
|
||||
);
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
throw lastError;
|
||||
});
|
||||
};
|
||||
|
||||
return workflow;
|
||||
}
|
||||
|
||||
// Use the custom middleware
|
||||
const workflow = withRetry(3, withLogging(createWorkflow()));
|
||||
|
||||
// Define events
|
||||
const startEvent = workflowEvent<string>();
|
||||
const resultEvent = workflowEvent<string>();
|
||||
|
||||
// Add handlers
|
||||
workflow.handle([startEvent], (event) => {
|
||||
// This handler might fail but will be retried
|
||||
if (Math.random() < 0.7) {
|
||||
throw new Error("Random failure");
|
||||
}
|
||||
return resultEvent.with(`Processed: ${event.data}`);
|
||||
});
|
||||
```
|
||||
|
||||
## Integrating with External Systems
|
||||
|
||||
You can extend your workflows to integrate with external systems:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent } from "llamaindex";
|
||||
|
||||
// Define events
|
||||
const fetchEvent = workflowEvent<string>();
|
||||
const successEvent = workflowEvent<any>();
|
||||
const failureEvent = workflowEvent<Error>();
|
||||
|
||||
// Create workflow
|
||||
const workflow = createWorkflow();
|
||||
|
||||
// Handle external API calls with proper error handling
|
||||
workflow.handle([fetchEvent], async (event) => {
|
||||
const { signal } = getContext();
|
||||
|
||||
try {
|
||||
// Use AbortSignal for cancellation support
|
||||
const response = await fetch(event.data, { signal });
|
||||
|
||||
if (!response.ok) {
|
||||
throw new Error(`HTTP error: ${response.status}`);
|
||||
}
|
||||
|
||||
const data = await response.json();
|
||||
return successEvent.with(data);
|
||||
} catch (error) {
|
||||
if (error.name === 'AbortError') {
|
||||
return failureEvent.with(new Error('Request was aborted'));
|
||||
}
|
||||
return failureEvent.with(error instanceof Error ? error : new Error(String(error)));
|
||||
}
|
||||
});
|
||||
|
||||
// Database integration example
|
||||
const dbQueryEvent = workflowEvent<{ collection: string; query: any }>();
|
||||
const dbResultEvent = workflowEvent<any[]>();
|
||||
|
||||
workflow.handle([dbQueryEvent], async (event) => {
|
||||
// Connect to database (pseudo-code)
|
||||
const db = await connectToDatabase();
|
||||
|
||||
try {
|
||||
const results = await db.collection(event.data.collection)
|
||||
.find(event.data.query)
|
||||
.toArray();
|
||||
|
||||
return dbResultEvent.with(results);
|
||||
} catch (error) {
|
||||
return failureEvent.with(error);
|
||||
} finally {
|
||||
await db.close();
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
## Handling Complex Asynchronous Patterns
|
||||
|
||||
LlamaIndex workflows excel at managing complex asynchronous patterns:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent, until, collect } from "llamaindex";
|
||||
|
||||
// Events for an orchestration workflow
|
||||
const orchestrateEvent = workflowEvent<string[]>();
|
||||
const taskEvent = workflowEvent<string>();
|
||||
const progressEvent = workflowEvent<{ task: string; progress: number }>();
|
||||
const taskCompleteEvent = workflowEvent<string>();
|
||||
const aggregateEvent = workflowEvent<any>();
|
||||
|
||||
// Create workflow
|
||||
const workflow = createWorkflow();
|
||||
|
||||
// Orchestrator: distribute tasks and collect results
|
||||
workflow.handle([orchestrateEvent], async (event) => {
|
||||
const { sendEvent, stream } = getContext();
|
||||
const tasks = event.data;
|
||||
|
||||
// Start all tasks
|
||||
tasks.forEach(task => sendEvent(taskEvent.with(task)));
|
||||
|
||||
// Track progress
|
||||
let completed = 0;
|
||||
const results = {};
|
||||
|
||||
// Process task completion and progress events
|
||||
for await (const event of until(stream, () => completed === tasks.length)) {
|
||||
if (progressEvent.include(event)) {
|
||||
console.log(`Task ${event.data.task}: ${event.data.progress}%`);
|
||||
} else if (taskCompleteEvent.include(event)) {
|
||||
completed++;
|
||||
results[event.data] = `Completed ${event.data}`;
|
||||
console.log(`Completed ${completed}/${tasks.length} tasks`);
|
||||
}
|
||||
}
|
||||
|
||||
return aggregateEvent.with(results);
|
||||
});
|
||||
|
||||
// Task processor
|
||||
workflow.handle([taskEvent], async (event) => {
|
||||
const { sendEvent } = getContext();
|
||||
const task = event.data;
|
||||
|
||||
// Simulate task processing with progress updates
|
||||
for (let progress = 0; progress <= 100; progress += 20) {
|
||||
sendEvent(progressEvent.with({ task, progress }));
|
||||
await new Promise(resolve => setTimeout(resolve, 200));
|
||||
}
|
||||
|
||||
return taskCompleteEvent.with(task);
|
||||
});
|
||||
```
|
||||
|
||||

|

|

This guide explores common patterns you can use to build more complex workflows with workflows.
|
||||
|
||||
## Fan-out (Parallelism)
|
||||
|
||||
One of the most powerful features of workflows is the ability to run tasks in parallel:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent, until, collect } from "llamaindex";
|
||||
|
||||
// Define events
|
||||
const startEvent = workflowEvent<string>();
|
||||
const processItemEvent = workflowEvent<number>();
|
||||
const resultEvent = workflowEvent<string>();
|
||||
const completeEvent = workflowEvent<string[]>();
|
||||
|
||||
// Create workflow
|
||||
const workflow = createWorkflow();
|
||||
|
||||
// Process start event: fan out to multiple processItemEvent events
|
||||
workflow.handle([startEvent], (start) => {
|
||||
const { sendEvent, stream } = getContext();
|
||||
|
||||
// Emit multiple events to be processed in parallel
|
||||
for (let i = 0; i < 10; i++) {
|
||||
sendEvent(processItemEvent.with(i));
|
||||
}
|
||||
|
||||
// Collect all resultEvents and emit a final completeEvent
|
||||
let condition = false;
|
||||
const results = collect(
|
||||
until(stream, () => condition)
|
||||
.filter((ev) => resultEvent.includes(ev))
|
||||
);
|
||||
|
||||
return completeEvent.with(results.map(event => event.data));
|
||||
});
|
||||
|
||||
// Process each item
|
||||
workflow.handle([processItemEvent], (event) => {
|
||||
// Process the item
|
||||
const processedValue = `Processed: ${event.data}`;
|
||||
|
||||
// If this is the last item, set the condition to stop collecting
|
||||
if (event.data === 9) {
|
||||
condition = true;
|
||||
}
|
||||
|
||||
return resultEvent.with(processedValue);
|
||||
});
|
||||
```
|
||||
|
||||
This pattern allows you to:
|
||||
1. Emit multiple events to be processed in parallel
|
||||
2. Collect results as they come in
|
||||
3. Complete once all parallel tasks are finished
|
||||
|
||||
## Conditional Branching
|
||||
|
||||
You can implement conditional logic in your workflows:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent } from "llamaindex";
|
||||
|
||||
const inputEvent = workflowEvent<number>();
|
||||
const evenNumberEvent = workflowEvent<string>();
|
||||
const oddNumberEvent = workflowEvent<string>();
|
||||
const resultEvent = workflowEvent<string>();
|
||||
|
||||
const workflow = createWorkflow();
|
||||
|
||||
// Branch based on whether the number is even or odd
|
||||
workflow.handle([inputEvent], (event) => {
|
||||
if (event.data % 2 === 0) {
|
||||
return evenNumberEvent.with(`${event.data} is even`);
|
||||
} else {
|
||||
return oddNumberEvent.with(`${event.data} is odd`);
|
||||
}
|
||||
});
|
||||
|
||||
// Handle even numbers
|
||||
workflow.handle([evenNumberEvent], (event) => {
|
||||
return resultEvent.with(`Even result: ${event.data}`);
|
||||
});
|
||||
|
||||
// Handle odd numbers
|
||||
workflow.handle([oddNumberEvent], (event) => {
|
||||
return resultEvent.with(`Odd result: ${event.data}`);
|
||||
});
|
||||
```
|
||||
|
||||
## Using Middleware
|
||||
|
||||
LlamaIndex workflows provide middleware that can enhance your workflows:
|
||||
|
||||
### `withStore` Middleware
|
||||
|
||||
The `withStore` middleware adds a persistent store to your workflow context:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent, withStore } from "llamaindex";
|
||||
|
||||
const startEvent = workflowEvent<void>();
|
||||
const incrementEvent = workflowEvent<number>();
|
||||
const resultEvent = workflowEvent<number>();
|
||||
|
||||
// Create a workflow with store middleware
|
||||
const workflow = withStore(
|
||||
() => ({
|
||||
count: 0,
|
||||
history: [] as number[],
|
||||
}),
|
||||
createWorkflow()
|
||||
);
|
||||
|
||||
// Increment the counter
|
||||
workflow.handle([startEvent], () => {
|
||||
const store = workflow.getStore();
|
||||
store.count += 1;
|
||||
store.history.push(store.count);
|
||||
return incrementEvent.with(store.count);
|
||||
});
|
||||
|
||||
// Return the current count
|
||||
workflow.handle([incrementEvent], (event) => {
|
||||
const store = workflow.getStore();
|
||||
return resultEvent.with(store.count);
|
||||
});
|
||||
```
|
||||
|
||||
### `withValidation` Middleware
|
||||
|
||||
The `withValidation` middleware adds compile-time and runtime validation to your workflows:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent, withValidation } from "llamaindex";
|
||||
|
||||
const startEvent = workflowEvent<string, "start">();
|
||||
const processEvent = workflowEvent<number, "process">();
|
||||
const resultEvent = workflowEvent<string, "result">();
|
||||
const disallowedEvent = workflowEvent<void, "disallowed">();
|
||||
|
||||
// Create a workflow with validation middleware
|
||||
// Define allowed event paths
|
||||
const workflow = withValidation(
|
||||
createWorkflow(),
|
||||
[
|
||||
[[startEvent], [processEvent]], // startEvent can only lead to processEvent
|
||||
[[processEvent], [resultEvent]], // processEvent can only lead to resultEvent
|
||||
]
|
||||
);
|
||||
|
||||
// This will pass validation
|
||||
workflow.strictHandle([startEvent], (sendEvent, start) => {
|
||||
sendEvent(processEvent.with(123)); // ✅ This is allowed
|
||||
});
|
||||
|
||||
// This would fail at compile time and runtime
|
||||
workflow.strictHandle([startEvent], (sendEvent, start) => {
|
||||
// sendEvent(disallowedEvent.with()); // ❌ This would cause an error
|
||||
// sendEvent(resultEvent.with("result")); // ❌ This would also cause an error
|
||||
});
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
LlamaIndex workflows provide built-in mechanisms for handling errors:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent } from "llamaindex";
|
||||
|
||||
const startEvent = workflowEvent<string>();
|
||||
const processEvent = workflowEvent<number>();
|
||||
const errorEvent = workflowEvent<Error>();
|
||||
const resultEvent = workflowEvent<string>();
|
||||
|
||||
const workflow = createWorkflow();
|
||||
|
||||
workflow.handle([startEvent], (start) => {
|
||||
try {
|
||||
const num = Number.parseInt(start.data, 10);
|
||||
if (isNaN(num)) {
|
||||
throw new Error("Invalid number");
|
||||
}
|
||||
return processEvent.with(num);
|
||||
} catch (err) {
|
||||
return errorEvent.with(err instanceof Error ? err : new Error(String(err)));
|
||||
}
|
||||
});
|
||||
|
||||
workflow.handle([processEvent], (event) => {
|
||||
return resultEvent.with(`Result: ${event.data * 2}`);
|
||||
});
|
||||
|
||||
workflow.handle([errorEvent], (event) => {
|
||||
return resultEvent.with(`Error: ${event.data.message}`);
|
||||
});
|
||||
```
|
||||
|
||||
You can also use the signal in `getContext()` to handle errors:
|
||||
|
||||
```ts
|
||||
workflow.handle([processEvent], () => {
|
||||
const { signal } = getContext();
|
||||
|
||||
signal.onabort = () => {
|
||||
console.error("Process aborted:", signal.reason);
|
||||
// Clean up resources
|
||||
};
|
||||
|
||||
// Your processing logic here
|
||||
});
|
||||
```
|
||||
|
||||
## Connecting with Server Endpoints
|
||||
|
||||
Workflow can be used as middleware in server frameworks like Express, Hono, or Fastify:
|
||||
|
||||
```ts
|
||||
import { Hono } from "hono";
|
||||
import { serve } from "@hono/node-server";
|
||||
import { createWorkflow, workflowEvent, createHonoHandler } from "llamaindex";
|
||||
|
||||
// Define events
|
||||
const queryEvent = workflowEvent<string>();
|
||||
const responseEvent = workflowEvent<string>();
|
||||
|
||||
// Create workflow
|
||||
const workflow = createWorkflow();
|
||||
|
||||
workflow.handle([queryEvent], (event) => {
|
||||
const response = `Processed: ${event.data}`;
|
||||
return responseEvent.with(response);
|
||||
});
|
||||
|
||||
// Create Hono app
|
||||
const app = new Hono();
|
||||
|
||||
// Set up workflow endpoint
|
||||
app.post(
|
||||
"/workflow",
|
||||
createHonoHandler(
|
||||
workflow,
|
||||
async (ctx) => queryEvent.with(await ctx.req.text()),
|
||||
responseEvent
|
||||
)
|
||||
);
|
||||
|
||||
// Start server
|
||||
serve(app, ({ port }) => {
|
||||
console.log(`Server started at http://localhost:${port}`);
|
||||
});
|
||||
```
|
||||
|

description: This page has been replaced with newer documentation

# ⚠️ Outdated Documentation
|
||||
|
||||
This documentation is for an older version of the workflow API. Please refer to the new llama-flow documentation:
|
||||
|
||||
- [Getting Started with llama-flow](./index.mdx)
|
||||
- [Basic Workflow Patterns](./basic-workflow.mdx)
|
||||
- [Advanced Event Handling](./advanced-events.mdx)
|
||||
|
||||
The new API provides a more lightweight and flexible approach to building workflows.
|
||||
|
||||
Inputs and outputs are the way to communicate between steps in a workflow. In the previous example,
|
||||
we used `StartEvent` and `StopEvent` to communicate between steps. However, you can use any type of event to communicate between steps.
|
||||
|
||||
## Multiple inputs
|
||||
|
||||
You can define multiple inputs for a step.
|
||||
|
||||
In the following example, we define a complex workflow with multiple inputs and outputs.
|
||||
|
||||
```ts twoslash
|
||||
import { Workflow, StartEvent, StopEvent, WorkflowEvent } from '@llamaindex/workflow';
|
||||
|
||||
class AEvent extends WorkflowEvent<string> {
|
||||
constructor(data: string) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
|
||||
class BEvent extends WorkflowEvent<number> {
|
||||
constructor(data: number) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
|
||||
class ResultEvent extends WorkflowEvent<string> {
|
||||
constructor(data: string) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
First, let's define the events that we will use in the workflow.
|
||||
|
||||
```ts twoslash
|
||||
import { Workflow, StartEvent, StopEvent, WorkflowEvent } from '@llamaindex/workflow';
|
||||
|
||||
class AEvent extends WorkflowEvent<string> {
|
||||
constructor(data: string) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
|
||||
class BEvent extends WorkflowEvent<number> {
|
||||
constructor(data: number) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
|
||||
class ResultEvent extends WorkflowEvent<string> {
|
||||
constructor(data: string) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
|
||||
const workflow = new Workflow<never, string, string>();
|
||||
|
||||
workflow.addStep({
|
||||
inputs: [StartEvent<string>],
|
||||
outputs: [StopEvent<string>]
|
||||
}, async (
|
||||
context,
|
||||
startEvent
|
||||
) => {
|
||||
const input = startEvent.data;
|
||||
const aEvent = await context.requireEvent(AEvent);
|
||||
const bEvent = await context.requireEvent(BEvent);
|
||||
const a = aEvent.data;
|
||||
const b = bEvent.data;
|
||||
return new StopEvent(`Hello, ${input}! A: ${a}, B: ${b}`);
|
||||
});
|
||||
|
||||
// ---cut---
|
||||
workflow.addStep({
|
||||
inputs: [AEvent, BEvent],
|
||||
outputs: [ResultEvent]
|
||||
}, async (
|
||||
context,
|
||||
aEvent,
|
||||
bEvent
|
||||
) => {
|
||||
const a = aEvent.data;
|
||||
const b = bEvent.data;
|
||||
return new ResultEvent(`A: ${a}, B: ${b}`);
|
||||
});
|
||||
```
|
||||
|
||||
This step means that it requires two events: `AEvent` and `BEvent`. It will return a `ResultEvent` with the data `A: ${a}, B: ${b}`.
|
||||
|
||||
## A or B input
|
||||
|
||||
If we want to have a step that can accept either `AEvent` or `BEvent`, we can define the step like this:
|
||||
|
||||
```ts twoslash
|
||||
import { Workflow, StartEvent, StopEvent, WorkflowEvent } from '@llamaindex/workflow';
|
||||
|
||||
class AEvent extends WorkflowEvent<string> {
|
||||
constructor(data: string) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
|
||||
class BEvent extends WorkflowEvent<number> {
|
||||
constructor(data: number) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
|
||||
class ResultEvent extends WorkflowEvent<string> {
|
||||
constructor(data: string) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
|
||||
const workflow = new Workflow<never, string, string>();
|
||||
|
||||
workflow.addStep({
|
||||
inputs: [StartEvent<string>],
|
||||
outputs: [StopEvent<string>]
|
||||
}, async (
|
||||
context,
|
||||
startEvent
|
||||
) => {
|
||||
const input = startEvent.data;
|
||||
const aEvent = await context.requireEvent(AEvent);
|
||||
const bEvent = await context.requireEvent(BEvent);
|
||||
const a = aEvent.data;
|
||||
const b = bEvent.data;
|
||||
return new StopEvent(`Hello, ${input}! A: ${a}, B: ${b}`);
|
||||
});
|
||||
|
||||
// ---cut---
|
||||
workflow.addStep({
|
||||
inputs: [WorkflowEvent.or(AEvent, BEvent)],
|
||||
outputs: [ResultEvent]
|
||||
}, async (
|
||||
context,
|
||||
aOrBEvent
|
||||
) => {
|
||||
if (aOrBEvent instanceof AEvent) {
|
||||
// ^?
|
||||
|
||||
|
||||
const a = aOrBEvent.data;
|
||||
// ^?
|
||||
|
||||
|
||||
return new ResultEvent(`A: ${a}`);
|
||||
} else {
|
||||
const b = aOrBEvent.data;
|
||||
// ^?
|
||||
|
||||
|
||||
return new ResultEvent(`B: ${b}`);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
This step means that it requires either `AEvent` or `BEvent`. It will return a `ResultEvent` with the data `A: ${a}` or `B: ${b}`.
|
||||
|
||||
You can still combine the logic with `context.requireEvent` to get the data from the event.

||||

||||

## Multiple outputs
|
||||
|
||||
You can define multiple outputs for a step.
|
||||
|
||||
```ts twoslash
|
||||
import { Workflow, StartEvent, StopEvent, WorkflowEvent } from '@llamaindex/workflow';
|
||||
|
||||
class AEvent extends WorkflowEvent<string> {
|
||||
constructor(data: string) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
|
||||
class BEvent extends WorkflowEvent<number> {
|
||||
constructor(data: number) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
|
||||
class ResultEvent extends WorkflowEvent<string> {
|
||||
constructor(data: string) {
|
||||
super(data);
|
||||
}
|
||||
}
|
||||
|
||||
const workflow = new Workflow<never, string, string>();
|
||||
// ---cut---
|
||||
workflow.addStep({
|
||||
inputs: [StartEvent<string>],
|
||||
outputs: [AEvent, BEvent]
|
||||
}, async (
|
||||
context,
|
||||
startEvent
|
||||
) => {
|
||||
const input = startEvent.data;
|
||||
if (Math.random() > 0.5) {
|
||||
return new AEvent(`Hello, ${input}!`);
|
||||
} else {
|
||||
return new BEvent(42);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
This step will return either an `AEvent` or a `BEvent` based on a random number.

title: Getting Started with Workflows
|

description: Learn how to use LlamaIndex's lightweight workflow engine for TypeScript
|
||||
---
|
||||
|
||||
Workflows are a simple and lightweight engine for TypeScript. Built with ❤️ by LlamaIndex.
|
||||
|
||||
- Minimal core API (\<\=2kb)
|
||||
- 100% Type safe
|
||||
- Event-driven, stream oriented programming
|
||||
- Support for multiple JS runtimes/frameworks
|
||||
|
||||
## Installation
|
||||
|
||||
It's directly included with the `llamaindex` package:
|
||||
|
||||
```shell
|
||||
npm i llamaindex
|
||||
```
|
||||
|
||||
But can also be installed separately:
|
||||
|
||||
```shell
|
||||
npm i @llama-flow/core
|
||||
|
||||
# or with yarn
|
||||
yarn add @llama-flow/core
|
||||
|
||||
# or with pnpm
|
||||
pnpm add @llama-flow/core
|
||||
```
|
||||
|
||||
## Key Concepts
|
||||
|
||||
- **Events**: Data carriers that flow through the workflow
|
||||
- **Handlers**: Functions that process events and emit new events
|
||||
- **Workflow**: Connects events and handlers together
|
||||
- **Context**: Runtime environment for a workflow execution
|
||||
|
||||
## Basic Usage
|
||||
|
||||
Let's build a simple workflow that processes a text input:
|
||||
|
||||
### 1. Define events
|
||||
|
||||
First, we need to define the events that will flow through our workflow:
|
||||
|
||||
```ts
|
||||
import { workflowEvent } from "llamaindex";
|
||||
|
||||
// Define input and output events
|
||||
const startEvent = workflowEvent<string>(); // Takes a string input
|
||||
const convertEvent = workflowEvent<Number>(); // Intermediate event
|
||||
const stopEvent = workflowEvent<1 | -1>(); // Final output event, returns 1 or -1
|
||||
```
|
||||
|
||||
### 2. Create a workflow and connect events
|
||||
|
||||
Next, we'll create our workflow and define how events are processed:
|
||||
|
||||
```ts
|
||||
import { createWorkflow } from "llamaindex";
|
||||
|
||||
const workflow = createWorkflow();
|
||||
|
||||
// Handle the start event: convert the string to a number
|
||||
workflow.handle([startEvent], (start) => {
|
||||
return convertEvent.with(Number.parseInt(start.data, 10));
|
||||
});
|
||||
|
||||
// Handle the convert event: determine if number is positive or negative
|
||||
workflow.handle([convertEvent], (convert) => {
|
||||
return stopEvent.with(convert.data > 0 ? 1 : -1);
|
||||
});
|
||||
```
|
||||
|
||||
### 3. Run the workflow
|
||||
|
||||
Finally, we can execute our workflow:
|
||||
|
||||
```ts
|
||||
// Create a workflow context and send the initial event
|
||||
const { stream, sendEvent } = workflow.createContext();
|
||||
sendEvent(startEvent.with("42"));
|
||||
|
||||
// Process the stream to get the result
|
||||
import { pipeline } from "node:stream/promises";
|
||||
|
||||
const result = await pipeline(stream, async function (source) {
|
||||
for await (const event of source) {
|
||||
if (stopEvent.include(event)) {
|
||||
return `Result: ${event.data === 1 ? 'positive' : 'negative'}`;
|
||||
}
|

}
|
||||
});
|
||||
|
||||
console.log(result); // "Result: positive"
|
||||
```
|
||||
|
||||
Or using the stream utilities:
|
||||
|
||||
```ts
|
||||
import { collect, until } from "llamaindex";
|
||||
|
||||
// Collect all events until we get a stopEvent
|
||||
const allEvents = await collect(until(stream, stopEvent));
|
||||
const finalEvent = allEvents[allEvents.length - 1];
|
||||
console.log(`Result: ${finalEvent.data === 1 ? 'positive' : 'negative'}`);
|
||||
```

description: Build AI applications by combining Workflows with other LlamaIndex features
|

|
||||
|
||||
This guide demonstrates how to combine the power of the workflow engine with LlamaIndex's retrieval and reasoning capabilities to build sophisticated AI applications.
|
||||
|
||||
## Basic RAG Workflow
|
||||
|
||||
Let's build a simple Retrieval-Augmented Generation (RAG) workflow:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent } from "llamaindex";
|
||||
import { Document, serviceContextFromDefaults, VectorStoreIndex } from "llamaindex";
|
||||
import { OpenAI, OpenAIEmbedding } from "@llamaindex/openai";
|
||||
import { Settings } from "@llamaindex/core/global"
|
||||
|
||||
// Define events
|
||||
const queryEvent = workflowEvent<string>();
|
||||
const retrieveEvent = workflowEvent<{ query: string; documents: Document[] }>();
|
||||
const generateEvent = workflowEvent<{ query: string; context: string }>();
|
||||
const responseEvent = workflowEvent<string>();
|
||||
|
||||
// Create workflow
|
||||
const workflow = createWorkflow();
|
||||
|
||||
// Set default global llm
|
||||
Settings.llm = new OpenAI({
|
||||
model: "gpt-4.1-mini",
|
||||
temperature: 0.2
|
||||
});
|
||||
|
||||
// Set the default global embedModel
|
||||
Settings.embedModel = new OpenAIEmbedding({
|
||||
model: "text-embedding-3-small",
|
||||
});
|
||||
|
||||
// Sample documents
|
||||
const documents = [
|
||||
new Document({
|
||||
text: "LlamaIndex is a data framework for LLM applications to ingest, structure, and access private or domain-specific data.",
|
||||
}),
|
||||
new Document({
|
||||
text: "LlamaIndex workflows are a lightweight workflow engine for TypeScript, designed to create event-driven processes.",
|
||||
}),
|
||||
];
|
||||
|
||||
// Create vector store index
|
||||
const index = await VectorStoreIndex.fromDocuments(documents);
|
||||
|
||||
// Handle query: Retrieve relevant documents
|
||||
workflow.handle([queryEvent], (event) => {
|
||||
const query = event.data;
|
||||
console.log(`Processing query: ${query}`);
|
||||
|
||||
// Retrieve relevant documents
|
||||
const retriever = index.asRetriever();
|
||||
const nodes = retriever.retrieve(query);
|
||||
|
||||
return retrieveEvent.with({
|
||||
query,
|
||||
documents: nodes.map(node => node.node),
|
||||
});
|
||||
});
|
||||
|
||||
// Handle retrieval results: Generate response
|
||||
workflow.handle([retrieveEvent], async (event) => {
|
||||
const { query, documents } = event.data;
|
||||
|
||||
// Combine document content as context
|
||||
const context = documents.map(doc => doc.text).join('\n\n');
|
||||
|
||||
return generateEvent.with({ query, context });
|
||||
});
|
||||
|
||||
// Handle generation: Produce final response
|
||||
workflow.handle([generateEvent], async (event) => {
|
||||
const { query, context } = event.data;
|
||||
|
||||
// Create a prompt with the context and query
|
||||
const prompt = `
|
||||
Context information:
|
||||
${context}
|
||||
|
||||
Based on the context information and no other knowledge, answer the following query:
|
||||
${query}
|
||||
`;
|
||||
|
||||
// Generate response with LLM
|
||||
const response = await Settings.llm.complete({ prompt });
|
||||
|
||||
return responseEvent.with(response.text);
|
||||
});
|
||||
|
||||
// Execute the workflow
|
||||
const { stream, sendEvent } = workflow.createContext();
|
||||
sendEvent(queryEvent.with("What is LlamaIndex?"));
|
||||
|
||||
// Process the stream
|
||||
for await (const event of stream) {
|
||||
if (responseEvent.include(event)) {
|
||||
console.log("Final response:", event.data);
|
||||
break;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Building a Chat Application
|
||||
|
||||
Let's create a more complex chat application that maintains conversation history:
|
||||
|
||||
```ts
|
||||
import { createWorkflow, workflowEvent, withStore } from "llamaindex";
|
||||
import { OpenAI, OpenAIEmbedding } from "@llamaindex/openai";
|
||||
import { Document, serviceContextFromDefaults, VectorStoreIndex } from "llamaindex";
|
||||
import { Settings } from "@llamaindex/core/global"
|
||||
|
||||
// Set default global llm
|
||||
Settings.llm = new OpenAI({
|
||||
model: "gpt-4.1-mini",
|
||||
temperature: 0.2
|
||||
});
|
||||
|
||||
// Set the default global embedModel
|
||||
Settings.embedModel = new OpenAIEmbedding({
|
||||
model: "text-embedding-3-small",
|
||||
});
|
||||
|
||||
// Define store type
|
||||
type ChatStore = {
|
||||
history: Array<{ role: string; content: string }>;
|
||||
documents: Document[];
|
||||
index: VectorStoreIndex | null;
|
||||
};
|
||||
|
||||
// Define events
|
||||
const initEvent = workflowEvent<Document[]>();
|
||||
const indexCreatedEvent = workflowEvent<VectorStoreIndex>();
|
||||
const userMessageEvent = workflowEvent<string>();
|
||||
const retrievalEvent = workflowEvent<{ query: string; nodes: any[] }>();
|
||||
const responseEvent = workflowEvent<{ message: { content: string } }>();
|
||||
|
||||
// Create workflow with store
|
||||
const workflow = withStore<ChatStore>(
|
||||
() => ({
|
||||
history: [],
|
||||
documents: [],
|
||||
index: null,
|
||||
}),
|
||||
createWorkflow()
|
||||
);
|
||||
|
||||
// Initialize the chat context
|
||||
workflow.handle([initEvent], async (event) => {
|
||||
const store = workflow.getStore();
|
||||
store.documents = event.data;
|
||||
|
||||
// Create index from documents
|
||||
const index = await VectorStoreIndex.fromDocuments(store.documents);
|
||||
|
||||
store.index = index;
|
||||
return indexCreatedEvent.with(index);
|
||||
});
|
||||
|
||||
// Process user message
|
||||
workflow.handle([userMessageEvent], (event) => {
|
||||
const userMessage = event.data;
|
||||
const store = workflow.getStore();
|
||||
|
||||
// Add user message to history
|
||||
store.history.push({
|
||||
role: "user",
|
||||
content: userMessage,
|
||||
});
|
||||
|
||||
if (!store.index) {
|
||||
throw new Error("Index not initialized yet");
|
||||
}
|
||||
|
||||
// Retrieve relevant context
|
||||
const retriever = store.index.asRetriever();
|
||||
const nodes = retriever.retrieve(userMessage);
|
||||
|
||||
return retrievalEvent.with({
|
||||
query: userMessage,
|
||||
nodes,
|
||||
});
|
||||
});
|
||||
|
||||
// Generate response from retrieval results
|
||||
workflow.handle([retrievalEvent], async (event) => {
|
||||
const { query, nodes } = event.data;
|
||||
const store = workflow.getStore();
|
||||
|
||||
// Context from retrieved nodes
|
||||
const context = nodes.map(node => node.node.text).join('\n\n');
|
||||
|
||||
// Create the system message with context
|
||||
const systemMessage = {
|
||||
role: "system",
|
||||
content: `You are a helpful assistant. Use the following information to answer the user's question:
|
||||
|
||||
${context}
|
||||
|
||||
Only use the information provided above to answer. If you don't know, say so.`,
|
||||
};
|
||||
|
||||
// Create full conversation history for the chat
|
||||
const messages = [
|
||||
systemMessage,
|
||||
...store.history,
|
||||
];
|
||||
|
||||
// Generate response
|
||||
const response = await Settings.llm.chat({
|
||||
messages,
|
||||
});
|
||||
|
||||
// Add assistant response to history
|
||||
store.history.push({
|
||||
role: "assistant",
|
||||
content: response.message.content,
|
||||
});
|
||||
|
||||
return responseEvent.with(response);
|
||||
});
|
||||
|
||||
// Example usage
|
||||
async function runChat() {
|
||||
// Sample documents
|
||||
const documents = [
|
||||
new Document({
|
||||
text: "LlamaIndex is a data framework for LLM applications to ingest, structure, and access private or domain-specific data.",
|

}),
|

new Document({
|

text: "LlamaIndex Workflows are a lightweight workflow engine for TypeScript, designed to create event-driven processes.",

];
|

|
||||
// Initialize the chat
|
||||
const { stream, sendEvent } = workflow.createContext();
|
||||
sendEvent(initEvent.with(documents));
|
||||
|
||||
// Wait for index creation
|
||||
for await (const event of stream) {
|
||||
if (indexCreatedEvent.include(event)) {
|
||||
console.log("Index created successfully");
|
||||
break;
|
||||
}
|
||||
}
|
||||
|
||||
// Start conversation
|
||||
async function sendUserMessage(message: string) {
|
||||
sendEvent(userMessageEvent.with(message));
|

|

for await (const event of stream) {
|

console.log("Assistant:", event.data.message.content);
|

return event.data.message.content;
|

}
|

}
|

}
|

await sendUserMessage("What is LlamaIndex?");
|

await sendUserMessage("Can you tell me about LlamaIndex workflows?");
|

await sendUserMessage("How might these two technologies work together?");
|

}
|

|

runChat();
|

## Conclusion
|
||||
|
||||
By combining the lightweight, event-driven workflow engine with LlamaIndex's powerful document indexing and querying capabilities, you can build sophisticated AI applications with clean, maintainable code.
|
||||
|
||||
The event-driven architecture allows you to:
|
||||
|
||||
1. Break complex processes into manageable steps
|
||||
2. Create reusable components for common AI workflows
|
||||
3. Easily debug and monitor each phase of execution
|
||||
4. Scale your applications by isolating resource-intensive steps
|
||||
5. Build more resilient systems with better error handling
|
||||
|
||||
As you build your own applications, consider how the patterns shown here can be adapted to your specific use cases.
