## 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.

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**](/typescript/framework/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.
|

title: With Cloudflare Worker
|
||||
description: In this guide, you'll learn how to use LlamaIndex with CloudFlare Worker
|
||||
---
|
||||
|
||||
Before you start, make sure you have try LlamaIndex.TS in Node.js to make sure you understand the basics.
|
||||
|
||||
<Card
|
||||
title="Getting Started with LlamaIndex.TS in Node.js"
|
||||
href="/docs/llamaindex/getting_started/installation/node"
|
||||
/>
|
||||
|
||||
Also, you need have the basic understanding of <a href='https://developers.cloudflare.com/workers/'><SiCloudflareworkers className="inline mr-2" color="#F38020" />Cloudflare Worker</a>.
|
||||
|
||||
## Adding environment variables
|
||||
|
||||
```ts
|
||||
export default {
|
||||
async fetch(request: Request, env: Env): Promise<Response> {
|
||||
const { setEnvs } = await import("@llamaindex/env");
|
||||
setEnvs(env);
|
||||
const { OpenAIAgent } = await import("@llamaindex/openai");
|
||||
// Start your code here
|
||||
return new Response("Hello, world!");
|
||||
},
|
||||
};
|
||||
```
|
||||
|
||||
Then, you need create `.dev.vars` and add LLM api keys for the local development, such as `OPENAI_API_KEY` for OpenAI API key.
|
||||
|
||||
<Callout type="warn">Do not commit the api key to git repository.</Callout>
|
||||
|
||||
## Integrating with Hono
|
||||
|
||||
```ts
|
||||
import { Hono } from "hono";
|
||||
|
||||
type Bindings = {
|
||||
OPENAI_API_KEY: string;
|
||||
};
|
||||
|
||||
const app = new Hono<{
|
||||
Bindings: Bindings;
|
||||
}>();
|
||||
|
||||
app.post("/llm", async (c) => {
|
||||
const { setEnvs } = await import("@llamaindex/env");
|
||||
setEnvs(c.env);
|
||||
|
||||
// ...
|
||||
|
||||
return new Response('Hello, world!');
|
||||
})
|
||||
|
||||
export default {
|
||||
fetch: app.fetch,
|
||||
};
|
||||
```
|
||||
|
||||
## Difference between Node.js and Cloudflare Worker
|
||||
|
||||
In Cloudflare Worker and similar serverless JS environment, you need to be aware of the following differences:
|
||||
|
||||
- Some Node.js modules are not available in Cloudflare Worker, such as `node:fs`, `node:child_process`, `node:cluster`...
|
||||
- You are recommend to design your code using network request, such as use `fetch` API to communicate with database, instead of a long-running process in Node.js.
|
||||
- Some of LlamaIndex.TS packages are not available in Cloudflare Worker, for example `@llamaindex/readers` and `@llamaindex/huggingface`.
|
||||
- The main `llamaindex` is designed to work in all JavaScript environment, including Cloudflare Worker. If you find any issue, please report to us.
|
||||
- `@llamaindex/env` is a JS environment binding module, which polyfill some Node.js/Modern Web API (for example, we have a memory based `fs` module, and Crypto API polyfill). It is designed to work in all JavaScript environment, including Cloudflare Worker.

|
||||
---
|
||||
|
||||
To install llamaindex, run the following command:
|
||||
## Quick Start
|
||||
|
||||
Install the core package:
|
||||
|
||||
```package-install
|
||||
npm i llamaindex
|
||||
```
|
||||
|
||||
In most cases, you'll also need an LLM package and the Workflow package to use LlamaIndex. For example, to use the OpenAI LLM with agents, you would install the following:
|
||||
In most cases, you'll also need an LLM provider and the Workflow package:
|
||||
|
||||
```package-install
|
||||
npm i @llamaindex/openai @llamaindex/workflow
|
||||
```
|
||||
|
||||
Go to [LLM APIs](/docs/llamaindex/modules/models/llms) to find out how to use other LLMs.
|
||||
## Environment Setup
|
||||
|
||||
### API Keys
|
||||
|
||||
## Frameworks
|
||||
Most LLM providers require API keys. Set your OpenAI key (or other provider):
|
||||
|
||||
LlamaIndex supports a wide range of frameworks and runtimes. Click on the card below to learn more.
|
||||
```bash
|
||||
export OPENAI_API_KEY=your-api-key
|
||||
```
|
||||
|
||||
Or use a `.env` file:
|
||||
|
||||
```bash
|
||||
echo "OPENAI_API_KEY=your-api-key" > .env
|
||||
```
|
||||
|
||||
<Callout type="warn">Never commit API keys to your repository.</Callout>
|
||||
|
||||
### Loading Environment Variables
|
||||
|
||||
For Node.js applications:
|
||||
|
||||
```bash
|
||||
node --env-file .env your-script.js
|
||||
```
|
||||
|
||||
For other environments, see the deployment-specific guides below.
|
||||
|
||||
## TypeScript Configuration
|
||||
|
||||
LlamaIndex.TS is built with TypeScript and provides excellent type safety. Add these settings to your `tsconfig.json`:
|
||||
|
||||
```json5
|
||||
{
|
||||
"compilerOptions": {
|
||||
// Essential for module resolution
|
||||
"moduleResolution": "bundler", // or "nodenext" | "node16" | "node"
|
||||
|
||||
// Required for Web Stream API support
|
||||
"lib": ["DOM.AsyncIterable"],
|
||||
|
||||
// Recommended for better compatibility
|
||||
"target": "es2020",
|
||||
"module": "esnext"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Running your first agent
|
||||
|
||||
### Set up
|
||||
|
||||
If you don't already have a project, you can create a new one in a new folder:
|
||||
|
||||
```package-install
|
||||
npm init
|
||||
npm i -D typescript @types/node
|
||||
npm i @llamaindex/openai @llamaindex/workflow llamaindex zod
|
||||
```
|
||||
|
||||
### Run the agent
|
||||
|
||||
Create the file `example.ts`. This code will:
|
||||
|
||||
- Create two tools for use by the agent:
|
||||
- A `sumNumbers` tool that adds two numbers
|
||||
- A `divideNumbers` tool that divides numbers
|
||||
- Give an example of the data structure we wish to generate
|
||||
- Prompt the LLM with instructions and the example, plus a sample transcript
|
||||
|
||||
<include cwd>../../examples/agents/agent/openai.ts</include>
|
||||
|
||||
To run the code:
|
||||
|
||||
```package-install
|
||||
npx tsx example.ts
|
||||
```
|
||||
|
||||
You should expect output something like:
|
||||
|
||||
```
|
||||
{
|
||||
result: '5 + 5 is 10. Then, 10 divided by 2 is 5.',
|
||||
state: {
|
||||
memory: Memory {
|
||||
messages: [Array],
|
||||
tokenLimit: 30000,
|
||||
shortTermTokenLimitRatio: 0.7,
|
||||
memoryBlocks: [],
|
||||
memoryCursor: 0,
|
||||
adapters: [Object]
|
||||
},
|
||||
scratchpad: [],
|
||||
currentAgentName: 'Agent',
|
||||
agents: [ 'Agent' ],
|
||||
nextAgentName: null
|
||||
}
|
||||
}
|
||||
Done
|
||||
```
|
||||
|
||||
## Performance Optimization
|
||||
|
||||
### Tokenization Speed
|
||||
|
||||
Install `gpt-tokenizer` for 60x faster tokenization (Node.js environments only):
|
||||
|
||||
```package-install
|
||||
npm i gpt-tokenizer
|
||||
```
|
||||
|
||||
LlamaIndex will automatically use this when available.

title: With Next.js
|

description: In this guide, you'll learn how to use LlamaIndex with Next.js.

Before you start, make sure you have try LlamaIndex.TS in Node.js to make sure you understand the basics.

|
||||
## Differences between Node.js and Next.js
|
||||
|
||||
Next.js is a React framework that has both server side compatibility and client side compatibility.
|
||||
This means that you need to be careful when using LlamaIndex.TS in Next.js.
|
||||
Don't leak the import data like API keys to the client side.
|
||||
|
||||
Also, in Next.js, there is build time and runtime. Some computations can be done at build time like Document embedding could be done at build time for better performance.
|
||||
Where as the `llamaindex` package is working with Next.js, some provider packages like `@llamaindex/huggingface` are not working well with Next.js. This is due to the upstream dependencies used by the provider package.
|
||||
|
||||
Make sure to use `withLlamaIndex` to make sure that LlamaIndex.TS works well with Next.js.
|
||||
|
||||
```js
|
||||
// next.config.mjs / next.config.ts
|
||||
import withLlamaIndex from "llamaindex/next";
|
||||
|
||||
/** @type {import('next').NextConfig} */
|
||||
const nextConfig = {};
|
||||
|
||||
export default withLlamaIndex(nextConfig);
|
||||
```
|
||||
|
||||
If you see any dependency issues, you are welcome to open an issue on the GitHub.
|
||||
|
||||
## Edge Runtime
|
||||
|
||||
[Vercel Edge Runtime](https://edge-runtime.vercel.app/) is a subset of Node.js APIs. Similar to [Cloudflare Workers](/docs/llamaindex/getting_started/installation/cloudflare#difference-between-nodejs-and-cloudflare-worker),
|
||||
it is a serverless platform that runs your code on the edge.
|
||||
|
||||
Not all features of Node.js are supported in Vercel Edge Runtime, so does LlamaIndex.TS, we are working on more compatibility with all JavaScript runtimes.

This guide covers integrating LlamaIndex.TS agents with Next.js applications.
|
||||
|
||||
## Essential Configuration
|
||||
|
||||
### Next.js Config
|
||||
|
||||
Use `withLlamaIndex` to ensure compatibility:
|
||||
|
||||
```javascript
|
||||
// next.config.mjs
|
||||
import withLlamaIndex from "llamaindex/next";
|
||||
|
||||
/** @type {import('next').NextConfig} */
|
||||
const nextConfig = {
|
||||
// Your existing config
|
||||
};
|
||||
|
||||
export default withLlamaIndex(nextConfig);
|
||||
```
|
||||
|
||||
## API Routes
|
||||
|
||||
### App Router (Recommended)
|
||||
|
||||
```typescript
|
||||
// app/api/chat/route.ts
|
||||
import { agent } from "@llamaindex/workflow";
|
||||
import { tool } from "llamaindex";
|
||||
import { openai } from "@llamaindex/openai";
|
||||
import { z } from "zod";
|
||||
import { NextRequest, NextResponse } from "next/server";
|
||||
|
||||
// Initialize agent once (consider using a singleton pattern)
|
||||
let myAgent: any = null;
|
||||
|
||||
async function initializeAgent() {
|
||||
if (myAgent) return myAgent;
|
||||
|
||||
try {
|
||||
const greetTool = tool({
|
||||
name: "greet",
|
||||
description: "Greets a user with their name",
|
||||
parameters: z.object({
|
||||
name: z.string(),
|
||||
}),
|
||||
execute: ({ name }) => `Hello, ${name}! How can I help you today?`,
|
||||
});
|
||||
|
||||
myAgent = agent({
|
||||
tools: [greetTool],
|
||||
llm: openai({ model: "gpt-4o-mini" }),
|
||||
});
|
||||
|
||||
return myAgent;
|
||||
} catch (error) {
|
||||
console.error("Failed to initialize agent:", error);
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
export async function POST(request: NextRequest) {
|
||||
try {
|
||||
const { message } = await request.json();
|
||||
|
||||
if (!message || typeof message !== 'string') {
|
||||
return NextResponse.json(
|
||||
{ error: "Message is required and must be a string" },
|
||||
{ status: 400 }
|
||||
);
|
||||
}
|
||||
|
||||
const agent = await initializeAgent();
|
||||
const result = await agent.run(message);
|
||||
|
||||
return NextResponse.json({ response: result.data });
|
||||
} catch (error) {
|
||||
console.error("Chat error:", error);
|
||||
return NextResponse.json(
|
||||
{ error: "Internal server error" },
|
||||
{ status: 500 }
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Pages Router (Legacy)
|
||||
|
||||
```typescript
|
||||
// pages/api/chat.ts
|
||||
import { agent } from "@llamaindex/workflow";
|
||||
import { tool } from "llamaindex";
|
||||
import { openai } from "@llamaindex/openai";
|
||||
import { z } from "zod";
|
||||
import type { NextApiRequest, NextApiResponse } from "next";
|
||||
|
||||
let myAgent: any = null;
|
||||
|
||||
async function initializeAgent() {
|
||||
if (myAgent) return myAgent;
|
||||
|
||||
const timeTool = tool({
|
||||
name: "getCurrentTime",
|
||||
description: "Gets the current time",
|
||||
parameters: z.object({}),
|
||||
execute: () => new Date().toISOString(),
|
||||
});
|
||||
|
||||
myAgent = agent({
|
||||
tools: [timeTool],
|
||||
llm: openai({ model: "gpt-4o-mini" }),
|
||||
});
|
||||
|
||||
return myAgent;
|
||||
}
|
||||
|
||||
export default async function handler(
|
||||
req: NextApiRequest,
|
||||
res: NextApiResponse
|
||||
) {
|
||||
if (req.method !== "POST") {
|
||||
return res.status(405).json({ error: "Method not allowed" });
|
||||
}
|
||||
|
||||
try {
|
||||
const { message } = req.body;
|
||||
|
||||
const agent = await initializeAgent();
|
||||
const result = await agent.run(message);
|
||||
|
||||
res.json({ response: result.data });
|
||||
} catch (error) {
|
||||
console.error("Chat error:", error);
|
||||
res.status(500).json({ error: "Internal server error" });
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Server Components
|
||||
|
||||
Initialize agents in server components:
|
||||
|
||||
```typescript
|
||||
// app/chat/page.tsx
|
||||
import { agent } from "@llamaindex/workflow";
|
||||
import { tool } from "llamaindex";
|
||||
import { openai } from "@llamaindex/openai";
|
||||
import { z } from "zod";
|
||||
|
||||
async function initializeAgent() {
|
||||
const helpTool = tool({
|
||||
name: "getHelp",
|
||||
description: "Provides help information",
|
||||
parameters: z.object({
|
||||
topic: z.string().optional(),
|
||||
}),
|
||||
execute: ({ topic }) => {
|
||||
if (topic) {
|
||||
return `Here's help for ${topic}: This is a helpful resource about ${topic}.`;
|
||||
}
|
||||
return "Available topics: general, troubleshooting, api, deployment";
|
||||
},
|
||||
});
|
||||
|
||||
return agent({
|
||||
tools: [helpTool],
|
||||
llm: openai({ model: "gpt-4o-mini" }),
|
||||
});
|
||||
}
|
||||
|
||||
export default async function ChatPage() {
|
||||
const chatAgent = await initializeAgent();
|
||||
|
||||
return (
|
||||
<div>
|
||||
<h1>Chat Interface</h1>
|
||||
<p>Agent initialized and ready to help!</p>
|
||||
{/* Your chat UI components */}
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Edge Runtime
|
||||
|
||||
The Edge Runtime has limited Node.js API access:
|
||||
|
||||
```typescript
|
||||
// app/api/chat-edge/route.ts
|
||||
import { NextRequest, NextResponse } from "next/server";
|
||||
|
||||
export const runtime = "edge";
|
||||
|
||||
export async function POST(request: NextRequest) {
|
||||
const { setEnvs } = await import("@llamaindex/env");
|
||||
setEnvs(process.env);
|
||||
|
||||
try {
|
||||
const { message } = await request.json();
|
||||
|
||||
const { agent } = await import("@llamaindex/workflow");
|
||||
const { tool } = await import("llamaindex");
|
||||
const { openai } = await import("@llamaindex/openai");
|
||||
const { z } = await import("zod");
|
||||
|
||||
const timeTool = tool({
|
||||
name: "time",
|
||||
description: "Gets current time",
|
||||
parameters: z.object({}),
|
||||
execute: () => new Date().toISOString(),
|
||||
});
|
||||
|
||||
const myAgent = agent({
|
||||
tools: [timeTool],
|
||||
llm: openai({ model: "gpt-4o-mini" }),
|
||||
});
|
||||
|
||||
const result = await myAgent.run(message);
|
||||
return NextResponse.json({ response: result.data });
|
||||
} catch (error) {
|
||||
return NextResponse.json({ error: error.message }, { status: 500 });
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Streaming Responses
|
||||
|
||||
Implement streaming for better user experience:
|
||||
|
||||
```typescript
|
||||
// app/api/chat-stream/route.ts
|
||||
import { agent } from "@llamaindex/workflow";
|
||||
import { tool } from "llamaindex";
|
||||
import { openai } from "@llamaindex/openai";
|
||||
import { agentStreamEvent } from "@llamaindex/workflow";
|
||||
import { NextRequest } from "next/server";
|
||||
import { z } from "zod";
|
||||
|
||||
// Initialize agent once (consider using a singleton pattern)
|
||||
let myAgent: any = null;
|
||||
|
||||
async function initializeAgent() {
|
||||
if (myAgent) return myAgent;
|
||||
|
||||
try {
|
||||
const greetTool = tool({
|
||||
name: "greet",
|
||||
description: "Greets a user with their name",
|
||||
parameters: z.object({
|
||||
name: z.string(),
|
||||
}),
|
||||
execute: ({ name }) => `Hello, ${name}! How can I help you today?`,
|
||||
});
|
||||
|
||||
myAgent = agent({
|
||||
tools: [greetTool],
|
||||
llm: openai({ model: "gpt-4o-mini" }),
|
||||
});
|
||||
|
||||
return myAgent;
|
||||
} catch (error) {
|
||||
console.error("Failed to initialize agent:", error);
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
|
||||
export async function POST(request: NextRequest) {
|
||||
const { message } = await request.json();
|
||||
|
||||
const stream = new ReadableStream({
|
||||
async start(controller) {
|
||||
try {
|
||||
const agent = await initializeAgent();
|
||||
const events = agent.runStream(message);
|
||||
|
||||
for await (const event of events) {
|
||||
if (agentStreamEvent.include(event)) {
|
||||

```
|
||||
|
||||
## Client-side Integration
|
||||
|
||||
### React Hook for API Calls
|
||||
|
||||
```typescript
|
||||
// hooks/useAgentChat.ts
|
||||
import { useState } from "react";
|
||||
|
||||
export function useAgentChat() {
|
||||
const [loading, setLoading] = useState(false);
|
||||
const [error, setError] = useState<string | null>(null);
|
||||
const [response, setResponse] = useState<string | null>(null);
|
||||
|
||||
const chat = async (message: string) => {
|
||||
setLoading(true);
|
||||
setError(null);
|
||||
|
||||
try {
|
||||
const res = await fetch("/api/chat", {
|
||||
method: "POST",
|
||||
headers: { "Content-Type": "application/json" },
|
||||
body: JSON.stringify({ message }),
|
||||
});
|
||||
|
||||
if (!res.ok) {
|
||||
throw new Error(`HTTP error! status: ${res.status}`);
|
||||
}
|
||||
|
||||
const data = await res.json();
|
||||
setResponse(data.response);
|
||||
} catch (err) {
|
||||
setError(err instanceof Error ? err.message : "An error occurred");
|
||||
} finally {
|
||||
setLoading(false);
|
||||
}
|
||||
};
|
||||
|
||||
return { chat, loading, error, response };
|
||||
}
|
||||
```
|
||||
|
||||
### Chat Component
|
||||
|
||||
```typescript
|
||||
// components/ChatInterface.tsx
|
||||
"use client";
|
||||
|
||||
import { useState } from "react";
|
||||
import { useAgentChat } from "@/hooks/useAgentChat";
|
||||
|
||||
export default function ChatInterface() {
|
||||
const [message, setMessage] = useState("");
|
||||
const { chat, loading, error, response } = useAgentChat();
|
||||
|
||||
const handleSubmit = async (e: React.FormEvent) => {
|
||||
e.preventDefault();
|
||||
if (!message.trim()) return;
|
||||
|
||||
await chat(message);
|
||||
setMessage("");
|
||||
};
|
||||
|
||||
return (
|

<form onSubmit={handleSubmit} className="mb-4">
|
||||
<input
|
||||
type="text"
|
||||
value={message}
|
||||
onChange={(e) => setMessage(e.target.value)}
|
||||
placeholder="Send a message..."
|
||||
className="w-full p-2 border rounded"
|
||||
disabled={loading}
|
||||
/>
|
||||
<button
|
||||
type="submit"
|
||||
disabled={loading || !message.trim()}
|
||||

</button>
|
||||
</form>
|
||||
|
||||
{error && (
|
||||
<div className="p-3 mb-4 bg-red-100 border border-red-400 text-red-700 rounded">
|
||||
Error: {error}
|
||||
</div>
|
||||
)}
|
||||
|
||||
{response && (
|
||||
<div className="p-3 bg-gray-100 border rounded">
|
||||
<strong>Agent:</strong>
|
||||
<p>{response}</p>
|
||||
</div>
|
||||
)}
|
||||
</div>
|
||||
);
|
||||
}

title: With Node.js/Bun/Deno
|
||||
description: In this guide, you'll learn how to use LlamaIndex with Node.js, Bun, and Deno.
|
||||
---
|
||||
|
||||
## Adding environment variables
|
||||
|
||||
By default, LlamaIndex uses OpenAI provider, which requires an API key. You can set the `OPENAI_API_KEY` environment variable to authenticate with OpenAI.
|
||||
|
||||
```shell
|
||||
export OPENAI_API_KEY=your-api-key
|
||||
```
|
||||
|
||||
Or you can use a `.env` file:
|
||||
|
||||
```shell
|
||||
echo "OPENAI_API_KEY=your-api-key" > .env
|
||||
node --env-file .env your-script.js
|
||||
```
|
||||
|
||||
<Callout type="warn">Do not commit the api key to git repository.</Callout>
|
||||
|
||||
For more information, see the [How to read environment variables from Node.js](https://nodejs.org/en/learn/command-line/how-to-read-environment-variables-from-nodejs).
|
||||
|
||||
## Performance Optimization
|
||||
|
||||
By the default, we are using `js-tiktoken` for tokenization. You can install `gpt-tokenizer` which is then automatically used by LlamaIndex to get a 60x speedup for tokenization:
|
||||
|
||||
```package-install
|
||||
npm i gpt-tokenizer
|
||||
```
|
||||
|
||||
**Note**: This only works for Node.js

---
|
||||
|

This guide covers adding LlamaIndex.TS agents to traditional server environments where you have full Node.js runtime access.
|
||||
|
||||
## Supported Runtimes
|
||||
|
||||
LlamaIndex.TS works seamlessly with:
|
||||
|
||||
- **Node.js** (v18+)
|
||||
- **Bun** (v1.0+)
|
||||
- **Deno** (v1.30+)
|
||||
|
||||
## Common Server Frameworks
|
||||
|
||||
### Express.js
|
||||
|
||||
```typescript
|
||||
import express from 'express';
|
||||
import { agent } from '@llamaindex/workflow';
|
||||
import { tool } from 'llamaindex';
|
||||
import { openai } from '@llamaindex/openai';
|
||||
import { z } from 'zod';
|
||||
|
||||
const app = express();
|
||||
app.use(express.json());
|
||||
|
||||
// Initialize agent once at startup
|
||||
let myAgent: any;
|
||||
|
||||
async function initializeAgent() {
|
||||
// Create tools for the agent
|
||||
const sumTool = tool({
|
||||
name: "sum",
|
||||
description: "Adds two numbers",
|
||||
parameters: z.object({
|
||||
a: z.number(),
|
||||
b: z.number(),
|
||||
}),
|
||||
execute: ({ a, b }) => a + b,
|
||||
});
|
||||
|
||||
const multiplyTool = tool({
|
||||
name: "multiply",
|
||||
description: "Multiplies two numbers",
|
||||
parameters: z.object({
|
||||
a: z.number(),
|
||||
b: z.number(),
|
||||
}),
|
||||
execute: ({ a, b }) => a * b,
|
||||
});
|
||||
|
||||
// Create the agent
|
||||
myAgent = agent({
|
||||
tools: [sumTool, multiplyTool],
|
||||
llm: openai({ model: "gpt-4o-mini" }),
|
||||
});
|
||||
}
|
||||
|
||||
app.post('/api/chat', async (req, res) => {
|
||||
try {
|
||||
const { message } = req.body;
|
||||
const result = await myAgent.run(message);
|
||||
res.json({ response: result.data });
|
||||
} catch (error) {
|
||||
res.status(500).json({ error: 'Chat failed' });
|
||||
}
|
||||
});
|
||||
|
||||
// Initialize and start server
|
||||
initializeAgent().then(() => {
|
||||
app.listen(3000, () => {
|
||||
console.log('Server running on port 3000');
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Fastify
|
||||
|
||||
```typescript
|
||||
import Fastify from 'fastify';
|
||||
import { agent } from '@llamaindex/workflow';
|
||||
import { tool } from 'llamaindex';
|

||||
execute: ({ a, b }) => a + b,
|
||||
});
|
||||
|
||||
myAgent = agent({
|
||||
tools: [sumTool],
|
||||
llm: openai({ model: "gpt-4o-mini" }),
|
||||
});
|
||||
}
|
||||
|
||||
fastify.post('/api/chat', async (request, reply) => {
|
||||
try {
|
||||
const { message } = request.body as { message: string };
|
||||
const result = await myAgent.run(message);
|
||||
return { response: result.data };

|
||||
description: Common issues and solutions when installing and deploying LlamaIndex.TS applications.
|
||||
---
|
||||
|
||||
This guide addresses common issues you might encounter when installing and deploying LlamaIndex.TS applications across different environments.
|
||||
|
||||
## Installation Issues
|
||||
|
||||
### Module Resolution Errors
|
||||
|
||||
**Problem:** Import errors or module not found errors
|
||||
|
||||
**Solution:** Ensure your `tsconfig.json` is properly configured:
|
||||
|
||||
```json5
|
||||
{
|
||||
"compilerOptions": {
|
||||
"moduleResolution": "bundler", // or "nodenext" | "node16" | "node"
|
||||
"lib": ["DOM.AsyncIterable"],
|
||||
"target": "es2020",
|
||||
"module": "esnext"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Alternative solution:** Try different module resolution strategies:
|
||||
|
||||
```bash
|
||||
# Clear node_modules and reinstall
|
||||
rm -rf node_modules package-lock.json
|
||||
npm install
|
||||
|
||||
# Or try with different package manager
|
||||
pnpm install
|
||||
# or
|
||||
yarn install
|
||||
```
|
||||
|
||||
### TypeScript Errors
|
||||
|
||||
**Problem:** TypeScript compilation errors with LlamaIndex imports
|
||||
|
||||
**Solution:** Ensure you have the correct TypeScript configuration:
|
||||
|
||||
```json5
|
||||
{
|
||||
"compilerOptions": {
|
||||
"strict": true,
|
||||
"skipLibCheck": true, // Skip type checking of node_modules
|
||||
"allowSyntheticDefaultImports": true,
|
||||
"esModuleInterop": true
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Package Compatibility Issues
|
||||
|
||||
**Problem:** Some packages don't work in certain environments
|
||||
|
||||
**Common incompatibilities:**
|
||||
- `@llamaindex/readers` - May not work in serverless environments
|
||||
- `@llamaindex/huggingface` - Limited browser/edge compatibility
|
||||
- File system readers - Don't work in browser/edge environments
|
||||
|
||||
**Solution:** Use environment-specific alternatives:
|
||||
|
||||
```typescript
|
||||
// Instead of file system readers in serverless
|
||||
// Use remote data sources
|
||||
async function loadDocumentsFromAPI() {
|
||||
const response = await fetch('https://api.example.com/documents');
|
||||
const data = await response.json();
|
||||
return data.map(doc => new Document(doc.content));
|
||||
}
|
||||
```
|
||||
|
||||
## Runtime Issues
|
||||
|
||||
### Memory Errors
|
||||
|
||||
**Problem:** Out of memory errors during index creation or querying
|
||||
|
||||
**Solution:** Optimize memory usage:
|
||||
|
||||
```typescript
|
||||
// Batch process large document sets
|
||||
async function batchProcessDocuments(documents: Document[], batchSize = 10) {
|
||||
const results = [];
|
||||
|
||||
for (let i = 0; i < documents.length; i += batchSize) {
|
||||
const batch = documents.slice(i, i + batchSize);
|
||||
const batchIndex = await VectorStoreIndex.fromDocuments(batch);
|
||||
results.push(batchIndex);
|
||||
|
||||
// Optional: Add delay between batches
|
||||
await new Promise(resolve => setTimeout(resolve, 100));
|
||||
}
|
||||
|
||||
return results;
|
||||
}
|
||||
```
|
||||
|
||||
**For serverless environments:**
|
||||
|
||||
```typescript
|
||||
// Use external vector stores instead of in-memory
|
||||
// TODO: Example with Pinecone, Weaviate, etc.
|
||||
// const vectorStore = new PineconeVectorStore(/* config */);
|
||||
// const index = await VectorStoreIndex.fromVectorStore(vectorStore);
|
||||
```
|
||||
|
||||
### API Rate Limiting
|
||||
|
||||
**Problem:** Rate limiting errors from LLM providers
|
||||
|
||||
**Solution:** Implement retry logic with exponential backoff:
|
||||
|
||||
```typescript
|
||||
async function queryWithRetry(queryEngine: any, question: string, maxRetries = 3) {
|
||||
for (let i = 0; i < maxRetries; i++) {
|
||||
try {
|
||||
return await queryEngine.query(question);
|
||||
} catch (error) {
|
||||
if (error.message.includes('rate limit') && i < maxRetries - 1) {
|
||||
const delay = Math.pow(2, i) * 1000; // Exponential backoff
|
||||
await new Promise(resolve => setTimeout(resolve, delay));
|
||||
continue;
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Tokenization Performance
|
||||
|
||||
**Problem:** Slow tokenization affecting performance
|
||||
|
||||
**Solution:** Install faster tokenizer (Node.js only):
|
||||
|
||||
```bash
|
||||
npm install gpt-tokenizer
|
||||
```
|
||||
|
||||
LlamaIndex will automatically use this for 60x faster tokenization.
|
||||
|
||||
## Bundling Issues
|
||||
|
||||
### Bundle Size Too Large
|
||||
|
||||
**Problem:** Large bundle sizes affecting performance
|
||||
|
||||
**Solution:** Use dynamic imports and code splitting:
|
||||
|
||||
```typescript
|
||||
// Lazy load LlamaIndex components
|
||||
const initializeLlamaIndex = async () => {
|
||||
const { VectorStoreIndex, SimpleDirectoryReader } = await import("llamaindex");
|
||||
return { VectorStoreIndex, SimpleDirectoryReader };
|
||||
};
|
||||
|
||||
// In your API route
|
||||
export async function POST(request: NextRequest) {
|
||||
const { VectorStoreIndex, SimpleDirectoryReader } = await initializeLlamaIndex();
|
||||
// Use the imported modules
|
||||
}
|
||||
```
|
||||
|
||||
### Webpack/Vite Bundling Issues
|
||||
|
||||
**Problem:** Bundler compatibility issues
|
||||
|
||||
**Solution for Next.js:**
|
||||
|
||||
```javascript
|
||||
// next.config.mjs
|
||||
import withLlamaIndex from "llamaindex/next";
|
||||
|
||||
const nextConfig = {
|
||||
webpack: (config, { isServer }) => {
|
||||
// Custom webpack configuration if needed
|
||||
if (!isServer) {
|
||||
config.resolve.fallback = {
|
||||
...config.resolve.fallback,
|
||||
fs: false,
|
||||
net: false,
|
||||
tls: false,
|
||||
};
|
||||
}
|
||||
return config;
|
||||
},
|
||||
};
|
||||
|
||||
export default withLlamaIndex(nextConfig);
|
||||
```
|
||||
|
||||
**Solution for Vite:**
|
||||
|
||||
```typescript
|
||||
// vite.config.ts
|
||||
import { defineConfig } from 'vite';
|
||||
|
||||
export default defineConfig({
|
||||
define: {
|
||||
global: 'globalThis',
|
||||
},
|
||||
resolve: {
|
||||
alias: {
|
||||
// Add aliases for problematic modules
|
||||
},
|
||||
},
|
||||
optimizeDeps: {
|
||||
include: ['llamaindex'],
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
## Environment-Specific Issues
|
||||
|
||||
### Node.js Version Compatibility
|
||||
|
||||
**Problem:** Node.js version compatibility issues
|
||||
|
||||
**Solution:** Use supported Node.js versions:
|
||||
|
||||
```json
|
||||
{
|
||||
"engines": {
|
||||
"node": ">=18.0.0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Check your Node.js version:**
|
||||
|
||||
```bash
|
||||
node --version
|
||||
```
|
||||
|
||||
### Cloudflare Workers Issues
|
||||
|
||||
**Problem:** Module not available in Cloudflare Workers
|
||||
|
||||
**Solution:** Use `@llamaindex/env` for environment compatibility:
|
||||
|
||||
```typescript
|
||||
export default {
|
||||
async fetch(request: Request, env: Env): Promise<Response> {
|
||||
const { setEnvs } = await import("@llamaindex/env");
|
||||
setEnvs(env);
|
||||
|
||||
// Your LlamaIndex code here
|
||||
},
|
||||
};
|
||||
```
|
||||
|
||||
### Vercel Edge Runtime Issues
|
||||
|
||||
**Problem:** Limited Node.js API access in Edge Runtime
|
||||
|
||||
**Solution:** Use standard runtime or adapt code:
|
||||
|
||||
```typescript
|
||||
// Force standard runtime
|
||||
export const runtime = "nodejs";
|
||||
|
||||
// Or adapt for edge
|
||||
export const runtime = "edge";
|
||||
|
||||
export async function POST(request: NextRequest) {
|
||||
// Use edge-compatible code only
|
||||
const { setEnvs } = await import("@llamaindex/env");
|
||||
setEnvs(process.env);
|
||||
|
||||
// Avoid file system operations
|
||||
// Use remote data sources
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Issues
|
||||
|
||||
### Slow Query Responses
|
||||
|
||||
**Problem:** Slow query performance
|
||||
|
||||
**Solution:** Implement caching and optimization:
|
||||
|
||||
```typescript
|
||||
import { LRUCache } from 'lru-cache';
|
||||
|
||||
const queryCache = new LRUCache<string, string>({
|
||||
max: 100,
|
||||
ttl: 1000 * 60 * 10, // 10 minutes
|
||||
});
|
||||
|
||||
export async function optimizedQuery(question: string, queryEngine: any) {
|
||||
// Check cache first
|
||||
const cached = queryCache.get(question);
|
||||
if (cached) return cached;
|
||||
|
||||
// Query and cache result
|
||||
const result = await queryEngine.query(question);
|
||||
queryCache.set(question, result);
|
||||
|
||||
return result;
|
||||
}
|
||||
```
|
||||
|
||||
### Cold Start Issues
|
||||
|
||||
**Problem:** Slow cold starts in serverless environments
|
||||
|
||||
**Solution:** Pre-warm your functions:
|
||||
|
||||
```typescript
|
||||
// Pre-initialize outside handler
|
||||
let cachedQueryEngine: any = null;
|
||||
|
||||
export async function handler(event: any) {
|
||||
if (!cachedQueryEngine) {
|
||||
cachedQueryEngine = await initializeQueryEngine();
|
||||
}
|
||||
|
||||
// Use cached engine
|
||||
return await cachedQueryEngine.query(question);
|
||||
}
|
||||
```
|
||||
|
||||
## Environment Variable Issues
|
||||
|
||||
### Missing API Keys
|
||||
|
||||
**Problem:** API key not found or invalid
|
||||
|
||||
**Solution:** Verify environment variable setup:
|
||||
|
||||
```typescript
|
||||
// Check if API key is available
|
||||
if (!process.env.OPENAI_API_KEY) {
|
||||
throw new Error('OPENAI_API_KEY environment variable is required');
|
||||
}
|
||||
|
||||
// For debugging (remove in production)
|
||||
console.log('API Key present:', !!process.env.OPENAI_API_KEY);
|
||||
```
|
||||
|
||||
### Environment Variable Loading
|
||||
|
||||
**Problem:** Environment variables not loading correctly
|
||||
|
||||
**Solution:** Use proper loading mechanisms:
|
||||
|
||||
```typescript
|
||||
// For Node.js
|
||||
import 'dotenv/config';
|
||||
|
||||
// For Next.js - use .env.local
|
||||
// Variables are automatically loaded
|
||||
|
||||
// For Cloudflare Workers
|
||||
export default {
|
||||
async fetch(request: Request, env: Env): Promise<Response> {
|
||||
// Use env parameter, not process.env
|
||||
const apiKey = env.OPENAI_API_KEY;
|
||||
// ...
|
||||
},
|
||||
};
|
||||
```
|
||||
|
||||
## Common Error Messages
|
||||
|
||||
### "Cannot find module 'llamaindex'"
|
||||
|
||||
**Cause:** Package not installed or module resolution issue
|
||||
|
||||
**Solution:**
|
||||
```bash
|
||||
npm install llamaindex
|
||||
```
|
||||
|
||||
### "Module not found: Can't resolve 'fs'"
|
||||
|
||||
**Cause:** File system modules used in browser/edge environment
|
||||
|
||||
**Solution:**
|
||||
```typescript
|
||||
// Use dynamic imports with fallbacks
|
||||
const loadDocuments = async () => {
|
||||
if (typeof window !== 'undefined') {
|
||||
// Browser environment - use alternative
|
||||
return await loadDocumentsFromAPI();
|
||||
} else {
|
||||
// Node.js environment - use file system
|
||||
const { SimpleDirectoryReader } = await import('llamaindex');
|
||||
return await new SimpleDirectoryReader('data').loadData();
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
### "ReferenceError: global is not defined"
|
||||
|
||||
**Cause:** Global polyfill missing in browser environments
|
||||
|
||||
**Solution:**
|
||||
```typescript
|
||||
// Add to your app entry point
|
||||
if (typeof global === 'undefined') {
|
||||
global = globalThis;
|
||||
}
|
||||
```
|
||||
|
||||
### "Cannot read properties of undefined (reading 'query')"
|
||||
|
||||
**Cause:** Query engine not properly initialized
|
||||
|
||||
**Solution:**
|
||||
```typescript
|
||||
// Always check initialization
|
||||
if (!queryEngine) {
|
||||
throw new Error('Query engine not initialized');
|
||||
}
|
||||
|
||||
// Or use optional chaining
|
||||
const response = await queryEngine?.query(question);
|
||||
```
|
||||
|
||||

// Or specific modules
|
||||
process.env.DEBUG = "llamaindex:vector-store";
|
||||
```
|
||||
|
||||
### Check Package Versions
|
||||
|
||||
```bash
|
||||

// Create minimal test case
|
||||
import { VectorStoreIndex } from 'llamaindex';
|
||||
|
||||
async function testBasic() {
|
||||
try {
|
||||
console.log('Testing basic import...');
|
||||
const index = new VectorStoreIndex();
|
||||
console.log('Success!');
|
||||
} catch (error) {
|
||||
console.error('Error:', error);
|
||||
}
|
||||
}
|
||||

title: With TypeScript
|
||||
description: In this guide, you'll learn how to use LlamaIndex with TypeScript
|
||||
---
|
||||
|
||||
LlamaIndex.TS is written in TypeScript and designed to be used in TypeScript projects.
|
||||
|
||||
We put a lot of work on strong typing to make sure you have a great typing experience with code completion such as:
|
||||
|
||||
```ts twoslash
|
||||
import { PromptTemplate } from 'llamaindex'
|
||||
const promptTemplate = new PromptTemplate({
|
||||
template: `Context information from multiple sources is below.
|
||||
---------------------
|
||||
{context}
|
||||
---------------------
|
||||
Given the information from multiple sources and not prior knowledge.
|
||||
Answer the query in the style of a Shakespeare play"
|
||||
Query: {query}
|
||||
Answer:`,
|
||||
templateVars: ["context", "query"],
|
||||
});
|
||||
// @noErrors
|
||||
promptTemplate.format({
|
||||
c
|
||||
//^|
|
||||
})
|
||||
```
|
||||
|
||||
## Enable TypeScript
|
||||
|
||||
Make sure to set [moduleResolution](https://www.typescriptlang.org/docs/handbook/modules/theory.html#module-resolution) in your `tsconfig.json` file:
|
||||
|
||||
```json5
|
||||
{
|
||||
compilerOptions: {
|
||||
// ⬇️ add this line to your tsconfig.json
|
||||
moduleResolution: "bundler", // or "nodenext" | "node16" | "node"
|
||||
},
|
||||
}
|
||||
```
|
||||

## Enable AsyncIterable for `Web Stream` API
|
||||
|
||||
Some modules uses `Web Stream` API like `ReadableStream` and `WritableStream`, you need to enable `DOM.AsyncIterable` in your `tsconfig.json`.
|
||||
|
||||
```json5
|
||||
{
|
||||
compilerOptions: {
|
||||
// ⬇️ add this lib to your tsconfig.json
|
||||
lib: ["DOM.AsyncIterable"],
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
```typescript
|
||||
import { tool } from 'llamaindex'
|
||||
import { agent } from "@llamaindex/workflow";
|
||||
import { openai } from "@llamaindex/openai";
|
||||
|
||||
Settings.llm = openai({
|
||||
model: "gpt-4o-mini",
|
||||
});
|
||||
|
||||
const addTool = tool({
|
||||
name: "add",
|
||||
description: "Adds two numbers",
|
||||
parameters: z.object({x: z.number(), y: z.number()}),
|
||||
execute: ({ x, y }) => x + y,
|
||||
});
|
||||
|
||||
const myAgent = agent({
|
||||
tools: [addTool],
|
||||
});
|
||||
|
||||
// Chat with the agent
|
||||
const context = myAgent.run("Hello, how are you?");
|
||||
|
||||
for await (const event of context) {
|
||||
if (event instanceof AgentStream) {
|
||||
for (const chunk of event.data.delta) {
|
||||
process.stdout.write(chunk); // stream response
|
||||
}
|
||||
} else {

## Why mention Vite?
|

|
||||
Vite.js is widely used in building many web applications, like React.js, even for some native app like [Electron](https://www.electronjs.org/).
|
||||
|
||||
However, it's not a ready-to-use solution for a Node.js-like application using Vite, as Vite is designed for web applications(run in browser).
|
||||
|
||||
There's some plugin/framework based on Vite, like [Waku.gg](https://github.com/dai-shi/waku), or [Electron Vite](https://electron-vite.org/)
|
||||
|
||||
For now, we have no clear solution for bundling LlamaIndex.TS with Vite, if you have any idea/solution, please let us know.

## Introduction
|
||||
|
||||
### What are agents?
|
||||
|
||||
[Agents](/typescript/framework/tutorials/agents/1_setup) are LLM-powered assistants that can reason, use external tools, and take actions to accomplish tasks such as research, data extraction, and automation.
|
||||
LlamaIndex.TS provides foundational building blocks for creating and orchestrating these agents.
|
||||
|
||||
### What are workflows?
|
||||
|
||||
[Workflows](/typescript/framework/tutorials/workflows) are multi-step, event-driven processes that combine agents, data connectors, and other tools to solve complex problems.
|
||||
With LlamaIndex.TS you can chain together retrieval, generation, and tool-calling steps and then deploy the entire pipeline as a microservice.
|
||||
|
||||
### What is context engineering?
|
||||
|
||||
LLMs come pre-trained on vast public corpora, but not on **your** private or domain-specific data.
|
||||
Context engineering bridges that gap by injecting the right pieces of your data into the LLM prompt at the right time.
|
||||
The most popular example is [Retrieval-Augmented Generation (RAG)](/typescript/framework/getting_started/concepts), but the same idea powers agent memory, evaluation, extraction, summarisation, and more.
|
||||
|
||||
LlamaIndex.TS gives you:
|
||||
|
||||
- **Data connectors** to ingest from APIs, files, SQL, and dozens more sources.
|
||||
- **Indexes & retrievers** to store and retrieve your data for LLM consumption.
|
||||
- **Agents and Engines** to query and use chat+reasoning interfaces over your data.
|
||||
- **Workflows** for fine-grained orchestration of your data and LLM-powered agents.
|
||||
- **Observability** integrations so you can iterate with confidence.
|
||||
|
||||
You can learn more about these concepts in our [concepts guide](/typescript/framework/getting_started/concepts).
|
||||
|
||||
## Use cases

# MCP Toolbox for Databases
|
||||
|
||||
[MCP Toolbox for Databases](https://github.com/googleapis/genai-toolbox) is an open source MCP server for databases. It was designed with enterprise-grade and production-quality in mind. It enables you to develop tools easier, faster, and more securely by handling the complexities such as connection pooling, authentication, and more.
|
||||
|
||||
Toolbox Tools can be seemlessly integrated with LlamaIndex applications. For more
|
||||
information on [getting
|
||||
started](https://googleapis.github.io/genai-toolbox/getting-started/local_quickstart_js/) or
|
||||
[configuring](https://googleapis.github.io/genai-toolbox/getting-started/configure/)
|
||||
Toolbox, see the
|
||||
[documentation](https://googleapis.github.io/genai-toolbox/getting-started/introduction/).
|
||||
|
||||

|
||||
|
||||
### Configure and deploy
|
||||
|
||||
Toolbox is an open source server that you deploy and manage yourself. For more
|
||||
instructions on deploying and configuring, see the official Toolbox
|
||||
documentation:
|
||||
|
||||
* [Installing the Server](https://googleapis.github.io/genai-toolbox/getting-started/introduction/#installing-the-server)
|
||||
* [Configuring Toolbox](https://googleapis.github.io/genai-toolbox/getting-started/configure/)
|
||||
|
||||
### Install client SDK
|
||||
|
||||
LlamaIndex relies on the `@toolbox-sdk/core` node package to use Toolbox. Install the
|
||||
package before getting started:
|
||||
|
||||
```shell
|
||||
npm install @toolbox-sdk/core
|
||||
```
|
||||
|
||||
### Loading Toolbox Tools
|
||||
|
||||
Once your Toolbox server is configured and up and running, you can load tools
|
||||
from your server using the SDK:
|
||||
|
||||
```javascript
|
||||
import { gemini, GEMINI_MODEL } from "@llamaindex/google";
|
||||
import { agent } from "@llamaindex/workflow";
|
||||
import { tool } from "llamaindex";
|
||||
import { ToolboxClient } from "@toolbox-sdk/core";
|
||||
|
||||
// Initialize LLM
|
||||
const llm = gemini({
|
||||
model: GEMINI_MODEL.GEMINI_2_0_FLASH,
|
||||
apiKey: process.env.GOOGLE_API_KEY,
|
||||
});
|
||||
|
||||
// Replace with your Toolbox Server URL
|
||||
const URL = 'https://127.0.0.1:5000';
|
||||
|
||||
const client = new ToolboxClient("http://127.0.0.1:5000");
|
||||
const toolboxTools = await client.loadToolset("my-toolset");
|
||||
|
||||
const getTool = (toolboxTool) => tool({
|
||||
name: toolboxTool.getName(),
|
||||
description: toolboxTool.getDescription(),
|
||||
parameters: toolboxTool.getParamSchema(),
|
||||
execute: toolboxTool
|
||||
});
|
||||
const tools = toolboxTools.map(getTool);
|
||||
|
||||
const myAgent = agent({
|
||||
tools: tools,
|
||||
llm,
|
||||
memory,
|
||||
systemPrompt: prompt,
|
||||
});
|
||||
const result = await myAgent.run(query);
|
||||
console.log(result);
|
||||
```
|
||||
|
||||

// Output: { temperature: 72, humidity: 50, windSpeed: 10 }

|

|

The agent will:
|

1. Use the weather tool to get the raw weather information
|

2. Process that information through the LLM
|
||||
3. Extract structured data according to your schema
|
||||
4. Return both the natural language response and the structured object
|
||||

title: Low-Level LLM Execution
|
||||
---
|
||||
|
||||
Sometimes your need more control over LLM interactions than what high-level agents provide. The `llm.exec` method makes it simple for you to make a single LLM call with tools but hides the complexity of executing the tools and generating the tool messages.
|
||||
|
||||
## When to Use `llm.exec`
|
||||
|
||||
Use `llm.exec` when you need to:
|
||||
- Build custom agent logic in [workflow](/typescript/framework/modules/agents/workflows) steps
|
||||
- Have precise control over message handling and tool execution
|
||||
- Extract structured data from LLM responses
|
||||
|
||||
## Basic Usage
|
||||
|
||||
The `llm.exec` method takes messages and tools as parameter and executes one LLM call.
|
||||
The LLM might either request to call one or more of the tools or generate an assistant message as result.
|
||||
For each tool call that is requested, `llm.exec` executes it and generates the two tool call messages (call and result). If no tool call is requested, just the assistant message is returned.
|
||||
|
||||
```ts
|
||||
import { openai } from "@llamaindex/openai";
|
||||
import { ChatMessage, tool } from "llamaindex";
|
||||
import z from "zod";
|
||||
|
||||
const llm = openai({ model: "gpt-4.1-mini" });
|
||||
const messages = [
|
||||
{
|
||||
content: "What's the weather like in San Francisco?",
|
||||
role: "user",
|
||||
} as ChatMessage,
|
||||
];
|
||||
|
||||
const { newMessages, toolCalls } = await llm.exec({
|
||||
messages,
|
||||
tools: [
|
||||
tool({
|
||||
name: "get_weather",
|
||||
description: "Get the current weather for a location",
|
||||
parameters: z.object({
|
||||
address: z.string().describe("The address"),
|
||||
}),
|
||||
execute: ({ address }) => {
|
||||
return `It's sunny in ${address}!`;
|
||||
},
|
||||
}),
|
||||
],
|
||||
});
|
||||
|
||||
// Add the new messages (including tool calls and responses) to your conversation
|
||||
messages.push(...newMessages);
|
||||
```
|
||||
|
||||
> `newMessages` is an array as each tool call generates two messages: a tool call message and the tool call result message.
|
||||
|
||||
## Structured Output
|
||||
|
||||
You can use `responseFormat` with a Zod schema to get structured data from the LLM response:
|
||||
|
||||
```ts
|
||||
import { openai } from "@llamaindex/openai";
|
||||
import { ChatMessage } from "llamaindex";
|
||||
import z from "zod";
|
||||
|
||||
const llm = openai({ model: "gpt-4.1-mini" });
|
||||
|
||||
const schema = z.object({
|
||||
title: z.string(),
|
||||
author: z.string(),
|
||||
year: z.number(),
|
||||
});
|
||||
|
||||
const messages = [
|
||||
{
|
||||
role: "user",
|
||||
content: "I have been reading La Divina Commedia by Dante Alighieri, published in 1321",
|
||||
} as ChatMessage,
|
||||
];
|
||||
|
||||
const { newMessages, toolCalls, object } = await llm.exec({
|
||||
messages,
|
||||
responseFormat: schema,
|
||||
});
|
||||
|
||||
console.log(object); // { title: "La Divina Commedia", author: "Dante Alighieri", year: 1321 }
|
||||
```
|
||||
|
||||
## Agent Loop Pattern
|
||||
|
||||
A common pattern is to use `llm.exec` in a loop until the LLM stops making tool calls:
|
||||
|
||||
```ts
|
||||
import { openai } from "@llamaindex/openai";
|
||||
import { ChatMessage, tool } from "llamaindex";
|
||||
import z from "zod";
|
||||
|
||||
async function runAgentLoop() {
|
||||
const llm = openai({ model: "gpt-4.1-mini" });
|
||||
const messages = [
|
||||
{
|
||||
content: "What's the weather like in San Francisco?",
|
||||
role: "user",
|
||||
} as ChatMessage,
|
||||
];
|
||||
|
||||
let exit = false;
|
||||
do {
|
||||
const { newMessages, toolCalls } = await llm.exec({
|
||||
messages,
|
||||
tools: [
|
||||
tool({
|
||||
name: "get_weather",
|
||||
description: "Get the current weather for a location",
|
||||
parameters: z.object({
|
||||
address: z.string().describe("The address"),
|
||||
}),
|
||||
execute: ({ address }) => {
|
||||
return `It's sunny in ${address}!`;
|
||||
},
|
||||
}),
|
||||
],
|
||||
});
|
||||
|
||||
console.log(newMessages);
|
||||
messages.push(...newMessages);
|
||||
|
||||
// Exit when no more tool calls are made
|
||||
exit = toolCalls.length === 0;
|
||||
} while (!exit);
|
||||
}
|
||||
```
|
||||
|
||||
## Streaming Support
|
||||
|
||||
For real-time responses, use the `stream` option to get the assistant's response as streamed tokens:
|
||||
|
||||
```ts
|
||||
import { openai } from "@llamaindex/openai";
|
||||
import { ChatMessage, tool } from "llamaindex";
|
||||
import z from "zod";
|
||||
|
||||
async function streamingAgentLoop() {
|
||||
const llm = openai({ model: "gpt-4o-mini" });
|
||||
const messages = [
|
||||
{
|
||||
content: "What's the weather like in San Francisco?",
|
||||
role: "user",
|
||||
} as ChatMessage,
|
||||
];
|
||||
|
||||
let exit = false;
|
||||
do {
|
||||
const { stream, newMessages, toolCalls } = await llm.exec({
|
||||
messages,
|
||||
tools: [
|
||||
tool({
|
||||
name: "get_weather",
|
||||
description: "Get the current weather for a location",
|
||||
parameters: z.object({
|
||||
address: z.string().describe("The address"),
|
||||
}),
|
||||
execute: ({ address }) => {
|
||||
return `It's sunny in ${address}!`;
|
||||
},
|
||||
}),
|
||||
],
|
||||
stream: true,
|
||||
});
|
||||
|
||||
// Stream the response token by token
|
||||
for await (const chunk of stream) {
|
||||
process.stdout.write(chunk.delta);
|
||||
}
|
||||
|
||||
messages.push(...newMessages());
|
||||
|
||||
exit = toolCalls.length === 0;
|
||||
} while (!exit);
|
||||
}
|
||||
```
|
||||
|
||||
> `newMessages` is a function when streaming. The reason is that the result only is available after streaming. Calling it before, will throw an error.
|
||||
|
||||
## Return Values
|
||||
|
||||
`llm.exec` returns an object with:
|
||||
|
||||
- **`newMessages`**: Array of new chat messages including the LLM response and any tool call messages (call or result). This is a function return the array when streaming.
|
||||
- **`toolCalls`**: Array of tool calls made by the LLM
|
||||
- **`object`**: The structured object when using `responseFormat` with a Zod schema (undefined if no schema is provided)
|
||||
- **`stream`**: Async iterable for streaming responses (only when `stream: true`)
|
||||
|
||||
## Best Practices
|
||||
|
||||
For using `llm.exec` in an agent loop, take care to:
|
||||
|
||||
1. **Maintain message history**: Always add `newMessages` to your conversation history
|
||||
2. **Set exit conditions**: Implement proper logic to avoid infinite loops
|
||||
3. **Handle structured output**: When using `responseFormat`, the `object` property contains your parsed data

Node parsers are a simple abstraction that take a list of `Document` objects, and chunk them into `Node` objects, such that each node is a specific chunk of the parent document. When a document is broken into nodes, all of it's attributes are inherited to the children nodes (i.e. `metadata`, text and metadata templates, etc.).

#### VectorBlock Configuration Options
|
||||
|
||||
The `vectorBlock` offers several configuration options to customize its behavior:
|
||||
|
||||
```ts
|
||||
vectorBlock({
|
||||
vectorStore: new QdrantVectorStore({ url: "http://localhost:6333" }),
|
||||
priority: 2,
|

formatTemplate: new PromptTemplate({ template: "Context: {{ context }}" }), // Custom formatting template
|
||||
nodePostprocessors: [/* custom postprocessors */], // Apply processing to retrieved nodes
|
||||
queryOptions: {
|
||||
similarityTopK: 3, // Number of top similar results to return (default: 2)
|
||||
mode: VectorStoreQueryMode.DEFAULT, // Query mode for the vector store
|
||||
sessionFilterKey: "session_id", // Metadata key for session filtering (default: "session_id")
|
||||
// Custom filters can be added here - session filter is automatically included
|
||||
filters: {
|
||||
filters: [
|
||||
{ key: "custom_field", value: "custom_value", operator: "==" }
|
||||
],
|
||||
condition: "and"
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
**Key Configuration Options:**
|
||||
|
||||
- **`retrievalContextWindow`**: Number of recent messages to consider when creating the retrieval query (default: 5). A larger window provides more context but may be less precise.
|
||||
- **`formatTemplate`**: Template for formatting retrieved information before adding to memory. Defaults to a simple context template.
|
||||
- **`nodePostprocessors`**: Array of postprocessors to apply to retrieved nodes, useful for filtering or transforming results.
|
||||
- **`queryOptions.similarityTopK`**: Number of most similar messages to retrieve from the vector store (default: 2).
|
||||
- **`queryOptions.sessionFilterKey`**: Metadata key used to isolate memory between different sessions (default: "session_id").
|
||||
- **`queryOptions.filters`**: Additional metadata filters for retrieval. The session filter is automatically added to ensure memory isolation.
|
||||
|
||||
**Session Isolation:**
|
||||
|
||||
The vectorBlock automatically adds a session filter using the block's ID to ensure that memories from different sessions don't interfere with each other. This filter uses the `sessionFilterKey` (default: "session_id") and can be customized if needed.

title: Custom Model Per Request
|
||||
---
|
||||
|
||||
There are scenarios, such as the case of a multi-tenant backend API, where it may be required to handle each request with a custom model.
|
||||
|
||||
In such a scenario, modifying the `Settings` object directly as follows is not recommended:
|
||||
|
||||
```typescript
|
||||
import { Settings } from 'llamaindex';
|
||||
import { OpenAIEmbedding } from '@llamaindex/embeddings-openai';
|
||||
|
||||
Settings.embedModel = new OpenAIEmbedding({ apiKey: 'CLIENT_API_KEY' });
|
||||
Settings.llm = openai({ apiKey: key, model: 'gpt-4o' })
|
||||
```
|
||||
|
||||
Setting `llm` and `embedModel` directly will lead to unpredictable responses, since `Settings` is global and mutable.
|
||||
This can lead to race conditions, as each request modifies `Settings.embedModel` or `Settings.llm`.
|
||||
|
||||
The recommended approach is to use `Settings.withEmbedModel` or `Settings.withLLM` as follows:
|
||||
|
||||
```typescript
|
||||
const embedModel = new OpenAIEmbedding({
|
||||
apiKey: process.env.OPENAI_API_KEY,
|
||||
});
|
||||
const llm = new OpenAI({ apiKey: process.env.OPENAI_API_KEY });
|
||||
|
||||
const llmResponse = await Settings.withEmbedModel(embedModel, async () => {
|
||||
return Settings.withLLM(llm, async () => {
|
||||
const path = "node_modules/llamaindex/examples/abramov.txt";
|
||||
const essay = await fs.readFile(path, "utf-8");
|
||||
// Create Document object with essay
|
||||
const document = new Document({ text: essay, id_: path });
|
||||
// Split text and create embeddings. Store them in a VectorStoreIndex
|
||||
const index = await VectorStoreIndex.fromDocuments([document]);
|
||||
// Query the index
|
||||
const queryEngine = index.asQueryEngine();
|
||||
const { message, sourceNodes } = await queryEngine.query({
|
||||
query: "What did the author do in college?",
|
||||
});
|
||||
// Return response with sources
|
||||
return message.content;
|
||||
});
|
||||
});
|
||||
```

||||

||||
