```package-install
npm i @llama-flow/core @llamaindex/openai
```
Workflows in LlamaIndexTS work by defining step functions that handle specific event types and emit new events.
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.
You can create a `Workflow` to do anything! Build an agent, a RAG flow, an extraction flow, or anything else you want.

## Getting Started
Let's explore a simple workflow example where a joke is generated and then critiqued and iterated on:
As an illustrative example, let's consider a naive workflow where a joke is generated and then critiqued.
```typescript
import { OpenAI } from "@llamaindex/openai";
import { createWorkflow, workflowEvent } from "@llama-flow/core";
import { withStore } from "@llama-flow/core/middleware/store";
<DynamicCodeBlock lang="ts" code={CodeSource} />
// Create LLM instance
const llm = new OpenAI({ model: "gpt-4.1-mini", apiKey: "..."});
// Define our workflow events
const startEvent = workflowEvent<string>(); // Input topic for joke
const jokeEvent = workflowEvent<{ joke: string }>(); // Intermediate joke
const critiqueEvent = workflowEvent<{ joke: string, critique: string }>(); // Intermediate critique
const resultEvent = workflowEvent<{ joke: string, critique: string }>(); // Final joke + critique
// Create our workflow
const jokeFlow = withStore(
() => ({
numIterations: 0,
maxIterations: 3,
}),
createWorkflow()
);
// Define handlers for each step
jokeFlow.handle([startEvent], async (event) => {
// Prompt the LLM to write a joke
const prompt = `Write your best joke about ${event.data}. Write the joke between <joke> and </joke> tags.`;
const response = await llm.complete({ prompt });
// Parse the joke from the response
const joke = response.text.match(/<joke>([\s\S]*?)<\/joke>/)?.[1]?.trim() ?? response.text;
return jokeEvent.with({ joke: joke });
});
jokeFlow.handle([jokeEvent], async (event) => {
// Prompt the LLM to critique the joke
const prompt = `Give a thorough critique of the following joke. If the joke needs improvement, put "IMPROVE" somewhere in the critique: ${event.data.joke}`;
const response = await llm.complete({ prompt });
// If the critique includes "IMPROVE", keep iterating, else, return the result
if (response.text.includes("IMPROVE")) {
return critiqueEvent.with({ joke: event.data.joke, critique: response.text });
}
return resultEvent.with({ joke: event.data.joke, critique: response.text });
});
jokeFlow.handle([critiqueEvent], async (event) => {
// Keep track of the number of iterations
const store = jokeFlow.getStore();
store.numIterations++;
// Write a new joke based on the previous joke and critique
const prompt = `Write a new joke based on the following critique and the original joke. Write the joke between <joke> and </joke> tags.\n\nJoke: ${event.data.joke}\n\nCritique: ${event.data.critique}`;
const response = await llm.complete({ prompt });
// Parse the joke from the response
const joke = response.text.match(/<joke>([\s\S]*?)<\/joke>/)?.[1]?.trim() ?? response.text;
// If we've done less than the max number of iterations, keep iterating
// else, return the result
if (store.numIterations < store.maxIterations) {
return jokeEvent.with({ joke: joke });
}
return resultEvent.with({ joke: joke, critique: event.data.critique });
});
// Usage
async function main() {
const { stream, sendEvent } = jokeFlow.createContext();
sendEvent(startEvent.with("pirates"));
let result: { joke: string, critique: string } | undefined;
for await (const event of stream) {
// console.log(event.data); optionally log the event data
if (resultEvent.include(event)) {
result = event.data;
break; // Stop when we get the final result
}
}
console.log(result);
}
main().catch(console.error);
```
There are a few moving pieces here, so let's go through this step by step.
There's a few moving pieces here, so let's go through this piece by piece.
### Defining Workflow Events
```typescript
const startEvent = workflowEvent<string>(); // Input topic for joke
const jokeEvent = workflowEvent<{ joke: string }>(); // Intermediate joke
const critiqueEvent = workflowEvent<{ joke: string, critique: string }>(); // Intermediate critique
const resultEvent = workflowEvent<{ joke: string, critique: string }>(); // Final joke + critique
export class JokeEvent extends WorkflowEvent<{ joke: string }> {}
```
Events are defined using the `workflowEvent` function and contain arbitrary data provided as a generic type. In this example, we have four events:
- `startEvent`: Takes a string input (the joke topic)
- `jokeEvent`: Contains an object with a joke property
- `critiqueEvent`: Contains both the joke and its critique, used for the feedback loop
- `resultEvent`: Contains the final joke and critique after any iterations
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 with Store Middleware
### Setting up the Workflow Class
```typescript
const jokeFlow = withStore(
() => ({
numIterations: 0,
maxIterations: 3,
}),
createWorkflow()
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
);
```
Our workflow is implemented using the `createWorkflow()` function, enhanced with the `withStore` middleware. The store provides shared state across all handlers, which in this case tracks:
- `numIterations`: Counts how many iterations of joke improvement we've done
- `maxIterations`: Sets a limit to prevent infinite loops
This store will be accesible within workflows by using the `jokeFlow.getStore()` function.
### Adding Handlers with Loops
We have three key handlers in our workflow:
1. The first handler processes the `startEvent`, generates an initial joke, and emits a `jokeEvent`:
### Workflow Exit Points
```typescript
jokeFlow.handle([startEvent], async (event) => {
// Prompt the LLM to write a joke
const prompt = `Write your best joke about ${event.data}. Write the joke between <joke> and </joke> tags.`;
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 });
// Parse the joke from the response
const joke = response.text.match(/<joke>([\s\S]*?)<\/joke>/)?.[1]?.trim() ?? response.text;
return jokeEvent.with({ joke: joke });
});
return new StopEvent(response.text);
};
```
2. The second handler handles the `jokeEvent`, critiques the joke, and either:
- Emits a `critiqueEvent` if the joke needs improvement
- Emits a `resultEvent` if the joke is good enough
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.handle([jokeEvent], async (event) => {
// Prompt the LLM to critique the joke
const prompt = `Give a thorough critique of the following joke. If the joke needs improvement, put "IMPROVE" somewhere in the critique: ${event.data.joke}`;
const response = await llm.complete({ prompt });
// If the critique includes "IMPROVE", keep iterating, else, return the result
if (response.text.includes("IMPROVE")) {
return critiqueEvent.with({ joke: event.data.joke, critique: response.text });
}
return resultEvent.with({ joke: event.data.joke, critique: response.text });
});
```
3. The third handler processes the `critiqueEvent`, generates an improved joke based on the critique, and either:
- Loops back to the joke evaluation (if under the iteration limit)
- Emits the final `resultEvent` (if iteration limit reached)
```typescript
jokeFlow.handle([critiqueEvent], async (event) => {
// Keep track of the number of iterations
const store = jokeFlow.getStore();
store.numIterations++;
// Write a new joke based on the previous joke and critique
const prompt = `Write a new joke based on the following critique and the original joke. Write the joke between <joke> and </joke> tags.\n\nJoke: ${event.data.joke}\n\nCritique: ${event.data.critique}`;
const response = await llm.complete({ prompt });
// Parse the joke from the response
const joke = response.text.match(/<joke>([\s\S]*?)<\/joke>/)?.[1]?.trim() ?? response.text;
// If we've done less than the max number of iterations, keep iterating
// else, return the result
if (store.numIterations < store.maxIterations) {
return jokeEvent.with({ joke: joke });
}
return resultEvent.with({ joke: joke, critique: event.data.critique });
});
jokeFlow.addStep(
{
inputs: [JokeEvent],
outputs: [StopEvent<string>],
},
critiqueJoke
);
```
### Running the Workflow
```typescript
async function main() {
const { stream, sendEvent } = jokeFlow.createContext();
sendEvent(startEvent.with("pirates"));
let result: { joke: string, critique: string } | undefined;
for await (const event of stream) {
// console.log(event.data); optionally log the event data
if (resultEvent.include(event)) {
result = event.data;
break; // Stop when we get the final result
}
}
console.log(result);
}
const result = await jokeFlow.run("pirates");
console.log(result.data.result);
```
To run the workflow, we:
1. Create a workflow context with `createContext()`
2. Trigger the initial event with `sendEvent()`
3. Listen to the event stream and process events as they arrive
4. Use `include()` to check if an event is of a specific type
5. Break the loop when we receive our final result
Lastly, we run the workflow. The `.run()` method is async, so we use await here to wait for the result.
### Using Stream Utilities
## Working with Shared Context/State
Workflows provide utility functions to make working with event streams easier:
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 { collect } from "@llama-flow/core/stream/consumer";
import { until } from "@llama-flow/core/stream/until";
import { HandlerContext } from "llamaindex";
// Create a workflow context and send the initial event
const { stream, sendEvent } = jokeFlow.createContext();
sendEvent(startEvent.with("pirates"));
type MyContextData = {
query: string;
intermediateResults: any[];
}
// Collect all events until we get a resultEvent
const allEvents = await collect(until(stream, resultEvent));
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);
// The last event will be the resultEvent
const finalEvent = allEvents[allEvents.length - 1];
console.log(finalEvent.data); // Output the joke and critique
return new StopEvent({ result });
};
```
The stream utilities make it easier to work with the asynchronous event flow. In this example, we use:
- `collect`: Aggregates all events into an array
- `until`: Creates a stream that emits events until a condition is met (in this case, until a resultEvent is received)
## Waiting for Multiple Events
You can combine these utilities with other stream operators like `filter` and `map` to create powerful processing pipelines.
The context does more than just hold data, it also provides utilities to buffer and wait for multiple events.
## Next Steps
For example, you might have a step that waits for a query and retrieved nodes before synthesizing a response:
To learn more about workflows, check out [the documentation in the tutorial section](../../../llamaflow).
```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.
## Examples
You can find many useful examples of using workflows in the [examples folder](https://github.com/run-llama/LlamaIndexTS/blob/main/examples/workflow).

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.).

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).
## AI-generated UI Components
The LlamaIndex server provides support for rendering workflow events using custom UI components, allowing you to extend and customize the chat interface.
These components can be auto-generated using an LLM by providing a JSON schema of the workflow event.
### UI Event Schema
To display custom UI components, your workflow needs to emit UI events that have an event type for identification and a data object:
```typescript
class UIEvent extends WorkflowEvent<{
type: "ui_event";
data: UIEventData;
}> {}
```
The `data` object can be any JSON object. To enable AI generation of the UI component, you need to provide a schema for that data (here we're using Zod):
```typescript
const MyEventDataSchema = z.object({
stage: z.enum(["retrieve", "analyze", "answer"]).describe("The current stage the workflow process is in."),
progress: z.number().min(0).max(1).describe("The progress in percent of the current stage"),
}).describe("WorkflowStageProgress");
type UIEventData = z.infer<typeof MyEventDataSchema>;
```
### Generate UI Components
The `generateEventComponent` function uses an LLM to generate a custom UI component based on the JSON schema of a workflow event. The schema should contain accurate descriptions of each field so that the LLM can generate matching components for your use case. We've done this for you in the example above using the `describe` function from Zod:
```typescript
import { OpenAI } from "llamaindex";
import { generateEventComponent } from "@llamaindex/server";
import { MyEventDataSchema } from "./your-workflow";
// Also works well with Claude 3.5 Sonnet and Google Gemini 2.5 Pro
const llm = new OpenAI({ model: "gpt-4.1" });
const code = generateEventComponent(MyEventDataSchema, llm);
```
After generating the code, we need to save it to a file. The file name must match the event type from your workflow (e.g., `ui_event.jsx` for handling events with `ui_event` type):
```ts
fs.writeFileSync("components/ui_event.jsx", code);
```
Feel free to modify the generated code to match your needs. If you're not satisfied with the generated code, we suggest improving the provided JSON schema first or trying another LLM.
> Note that `generateEventComponent` is generating JSX code, but you can also provide a TSX file.
### Server Setup
To use the generated UI components, you need to initialize the LlamaIndex server with the `componentsDir` that contains your custom UI components:
```ts
new LlamaIndexServer({
workflow: createWorkflow,
uiConfig: {
appTitle: "LlamaIndex App",
componentsDir: "components",
},
}).start();
```

- Your workflows can use both folders to store and access files. By convention, the `data` folder is used for documents that are ingested, and the `output` folder is used for documents generated by the workflow.
- 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 a fresh workflow instance for each request.
2. Use environment variables for sensitive configuration (e.g., API keys).
3. Use starter questions to guide users in the chat UI.

In LlamaIndex, an agent is a semi-autonomous piece of software powered by an LLM that is given a task and executes a series of steps towards solving that task. It is given a set of tools, which can be anything from arbitrary functions up to full LlamaIndex query engines, and it selects the best available tool to complete each step. When each step is completed, the agent judges whether the task is now complete, in which case it returns a result to the user, or whether it needs to take another step, in which case it loops back to the start.

title: Inputs / Outputs
description: Learn how to use different inputs and outputs in your 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.
