```js
// next.config.js
const withLlamaIndex = require("llamaindex/next");
module.exports = withLlamaIndex({

## Tips when using in non-Node.js environments
## Using NextJS
When you are importing `llamaindex` in a non-Node.js environment(such as React Server Components, Cloudflare Workers, etc.)
Some classes are not exported from top-level entry file.
If you're using the NextJS App Router, you can choose between the Node.js and the [Edge runtime](https://nextjs.org/docs/app/building-your-application/rendering/edge-and-nodejs-runtimes#edge-runtime).
The reason is that some classes are only compatible with Node.js runtime,(e.g. `PDFReader`) which uses Node.js specific APIs(like `fs`, `child_process`, `crypto`).
If you need any of those classes, you have to import them instead directly though their file path in the package.
Here's an example for importing the `PineconeVectorStore` class:
With NextJS 13 and 14, using the Node.js runtime is the default. You can explicitly set the Edge runtime in your [router handler](https://nextjs.org/docs/app/building-your-application/routing/route-handlers) by adding this line:
```typescript
import { PineconeVectorStore } from "llamaindex/storage/vectorStore/PineconeVectorStore";
export const runtime = "edge";
```
The following sections explain further differences in using the Node.js or Edge runtime.
### Using the Node.js runtime
Add the following config to your `next.config.js` to ignore specific packages in the server-side bundling:
```js
// next.config.js
/** @type {import('next').NextConfig} */
const nextConfig = {
experimental: {
serverComponentsExternalPackages: ["pdf2json", "@zilliz/milvus2-sdk-node"],
},
webpack: (config) => {
config.resolve.alias = {
...config.resolve.alias,
sharp$: false,
"onnxruntime-node$": false,
};
return config;
},
};
module.exports = nextConfig;
```
### Using the Edge runtime
We publish a dedicated package (`@llamaindex/edge` instead of `llamaindex`) for using the Edge runtime. To use it, first install the package:
```shell
pnpm install @llamaindex/edge
```
> _Note_: Ensure that your `package.json` doesn't include the `llamaindex` package if you're using `@llamaindex/edge`.
Then make sure to use the correct import statement in your code:
```typescript
// replace 'llamaindex' with '@llamaindex/edge'
import {} from "@llamaindex/edge";
```
A further difference is that the `@llamaindex/edge` package doesn't export classes from the `readers` or `storage` folders. The reason is that most of these classes are not compatible with the Edge runtime.
If you need any of those classes, you have to import them instead directly. Here's an example for importing the `PineconeVectorStore` class:
```typescript
import { PineconeVectorStore } from "@llamaindex/edge/storage/vectorStore/PineconeVectorStore";
```
As the `PDFReader` is not working with the Edge runtime, here's how to use the `SimpleDirectoryReader` with the `LlamaParseReader` to load PDFs:
```typescript
import { SimpleDirectoryReader } from "llamaindex/readers/SimpleDirectoryReader";
import { LlamaParseReader } from "llamaindex/readers/LlamaParseReader";
import { SimpleDirectoryReader } from "@llamaindex/edge/readers/SimpleDirectoryReader";
import { LlamaParseReader } from "@llamaindex/edge/readers/LlamaParseReader";
export const DATA_DIR = "./data";

## What's new in LlamaIndexTS v0.3.0
## Agents
In this release, we've not only ported the Agent module from the LlamaIndex Python version but have significantly
enhanced it to be more powerful and user-friendly for JavaScript/TypeScript applications.
Starting from v0.3.0, we are introducing multiple agents specifically designed for RAG applications, including:
- `OpenAIAgent`
- `AnthropicAgent`
- `ReActAgent`:
```ts
import { OpenAIAgent } from "llamaindex";
import { tools } from "./tools";
const agent = new OpenAIAgent({
tools: [...tools],
});
const { response } = await agent.chat({
message: "What is weather today?",
stream: false,
});
console.log(response.message.content);
```
We are also introducing the abstract AgentRunner class, which allows you to create your own agent by simply implementing
the task handler.
```ts
import { AgentRunner, OpenAI } from "llamaindex";
class MyLLM extends OpenAI {}
export class MyAgentWorker extends AgentWorker<MyLLM> {
taskHandler = MyAgent.taskHandler;
}
export class MyAgent extends AgentRunner<MyLLM> {
constructor(params: Params) {
super({
llm: params.llm,
chatHistory: params.chatHistory ?? [],
systemPrompt: params.systemPrompt ?? null,
runner: new MyAgentWorker(),
tools:
"tools" in params
? params.tools
: params.toolRetriever.retrieve.bind(params.toolRetriever),
});
}
// create store is a function to create a store for each task, by default it only includes `messages` and `toolOutputs`
createStore = AgentRunner.defaultCreateStore;
static taskHandler: TaskHandler<Anthropic> = async (step, enqueueOutput) => {
const { llm, stream } = step.context;
// initialize the input
const response = await llm.chat({
stream,
messages: step.context.store.messages,
});
// store the response for next task step
step.context.store.messages = [
...step.context.store.messages,
response.message,
];
// your logic here to decide whether to continue the task
const shouldContinue = Math.random(); /* <-- replace with your logic here */
enqueueOutput({
taskStep: step,
output: response,
isLast: !shouldContinue,
});
if (shouldContinue) {
const content = await someHeavyFunctionCall();
// if you want to continue the task, you can insert your new context for the next task step
step.context.store.messages = [
...step.context.store.messages,
{
content,
role: "user",
},
];
}
};
}
```
### Web Stream API for Streaming response
Web Stream is a web standard utilized in many modern web frameworks and libraries (like React 19, Deno, Node 22). We
have migrated streaming responses to Web Stream to ensure broader compatibility.
For instance, you can use the streaming response in a simple HTTP Server:
```ts
import { createServer } from "http";
import { OpenAIAgent } from "llamaindex";
import { OpenAIStream, streamToResponse } from "ai";
import { tools } from "./tools";
const agent = new OpenAIAgent({
tools: [...tools],
});
const server = createServer(async (req, res) => {
const response = await agent.chat({
message: "What is weather today?",
stream: true,
});
// Transform the response into a string readable stream
const stream: ReadableStream<string> = response.pipeThrough(
new TransformStream({
transform: (chunk, controller) => {
controller.enqueue(chunk.response.delta);
},
}),
);
// Pipe the stream to the response
streamToResponse(stream, res);
});
server.listen(3000);
```
Or it can be integrated into React Server Components (RSC) in Next.js:
```tsx
// app/actions/index.tsx
"use server";
import { createStreamableUI } from "ai/rsc";
import { OpenAIAgent } from "llamaindex";
import type { ChatMessage } from "llamaindex/llm/types";
export async function chatWithAgent(
question: string,
prevMessages: ChatMessage[] = [],
) {
const agent = new OpenAIAgent({
tools: [],
});
const responseStream = await agent.chat({
stream: true,
message: question,
chatHistory: prevMessages,
});
const uiStream = createStreamableUI(<div>loading...</div>);
responseStream
.pipeTo(
new WritableStream({
start: () => {
uiStream.update("response:");
},
write: async (message) => {
uiStream.append(message.response.delta);
},
}),
)
.catch(uiStream.error);
return uiStream.value;
}
```
```tsx
// app/src/page.tsx
"use client";
import { chatWithAgent } from "@/actions";
import type { JSX } from "react";
import { useFormState } from "react-dom";
export const runtime = "edge";
export default function Home() {
const [state, action] = useFormState<JSX.Element | null>(async () => {
return chatWithAgent("hello!", []);
}, null);
return (
<main>
{state}
<form action={action}>
<button>Chat</button>
</form>
</main>
);
}
```
## Improvement in LlamaIndexTS v0.3.0
### Better TypeScript support
We have made significant improvements to the type system to ensure that all code is thoroughly checked before it is
published. This ongoing enhancement has already resulted in better module reliability and developer experience.
For example, we have improved `FunctionTool` type with generic support:
```ts
type Input = {
a: number;
b: number;
};
const sumNumbers = FunctionTool.from<Input>(
({ a, b }) => `${a + b}`, // a and b will be checked as number
// JSON schema will be an error if you type wrong.
{
name: "sumNumbers",
description: "Use this function to sum two numbers",
parameters: {
type: "object",
properties: {
a: {
type: "number",
description: "The first number",
},
b: {
type: "number",
description: "The second number",
},
},
required: ["a", "b"],
},
},
);
```
![type checking](./img/function_tool_example.png)
### Better Next.js, Deno, Cloudflare Worker, and Waku(Vite) support
In addition to Node.js, LlamaIndexTS now offers enhanced support for Next.js, Deno, and Cloudflare Workers, making it
more versatile across different platforms.
For now, you can install llamaindex and directly import it into your existing Next.js, Deno or Cloudflare Worker project
**without any extra configuration**.
#### [Deno](https://deno.com/)
You can use LlamaIndexTS in Deno by installation through JSR:
```sh
jsr add @llamaindex/core
```
#### [Cloudflare Worker](https://developers.cloudflare.com/workers/)
For Cloudflare Workers, here is a starter template:
```typescript
export default {
async fetch(
request: Request,
env: Env,
ctx: ExecutionContext,
): Promise<Response> {
const { setEnvs } = await import("@llamaindex/env");
setEnvs(env);
const { OpenAIAgent } = await import("llamaindex");
const agent = new OpenAIAgent({
tools: [],
});
const responseStream = await agent.chat({
stream: true,
message: "Hello? What is the weather today?",
});
const textEncoder = new TextEncoder();
const response = responseStream.pipeThrough(
new TransformStream({
transform: (chunk, controller) => {
controller.enqueue(textEncoder.encode(chunk.response.delta));
},
}),
);
return new Response(response);
},
};
```
### [Waku (Vite)](https://waku.gg/)
Waku powered by Vite is a minimal React framework that supports multiple JS environments, including Deno, Cloudflare, and
Node.js.
You can use LlamaIndexTS with Node.js output to enable full Node.js support with React.
```sh
npm install llamaindex
```
```ts
// file: src/actions.ts
"use server";
import { Document, VectorStoreIndex } from "llamaindex";
import { readFile } from "node:fs/promises";
const path = "node_modules/llamaindex/examples/abramov.txt";
const essay = await 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]);
const queryEngine = index.asQueryEngine();
export async function chatWithAI(question: string): Promise<string> {
const { response } = await queryEngine.query({ query: question });
return response;
}
```
```tsx
// file: src/pages/index.tsx
import { chatWithAI } from "./actions";
export default async function HomePage() {
return (
<div>
<Chat askQuestion={chatWithAI} />
</div>
);
}
```
```tsx
// file: src/components/Chat.tsx
"use client";
export type ChatProps = {
askQuestion: (question: string) => Promise<string>;
};
export const Chat = (props: ChatProps) => {
const [response, setResponse] = useState<string | null>(null);
return (
<section className="border-blue-400 -mx-4 mt-4 rounded border border-dashed p-4">
<h2 className="text-lg font-bold">Chat with AI</h2>
{response ? (
<p className="text-sm text-gray-600 max-w-sm">{response}</p>
) : null}
<form
action={async (formData) => {
const question = formData.get("question") as string | null;
if (question) {
setResponse(await props.askQuestion(question));
}
}}
>
<input
type="text"
name="question"
className="border border-gray-400 rounded-sm px-2 py-0.5 text-sm"
/>
<button className="rounded-sm bg-black px-2 py-0.5 text-sm text-white">
Ask
</button>
</form>
</section>
);
};
```
```shell
waku dev # development mode
waku build # build for production
waku start # start the production server
```
Note that not all the modules are supported in all JS environments because of
lack of the file system, network API,
and incompatibility with the Node.js API by upstream dependencies.
But we are trying to make it more compatible with all the environments.
## What's the next?
As we continue to develop LlamaIndexTS, our focus remains on providing more comprehensive and powerful tools for
creating custom agents.
### Align with the Python `llama-index`
We aim to align LlamaIndexTS with the Python version to ensure API consistency and ease of use for developers familiar
with the Python ecosystem.
### Align with the Web Standard and JS development
Not all python APIs are compatible and easy to use in JavaScript/TypeScript.
We are trying to make the API more compatible with the Web Standard and JavaScript modern development.
### More Agents
Future releases will introduce more agents from the Python Llama-Index and explore APIs tailored to real-world use
cases.
### 🧪 `@llamaindex/tool`
We are exploring innovative ways to create tools for agents. The `@llamaindex/tool` library allows you to transform any
function into a tool for an agent, simplifying the development process and reducing runtime costs.
```ts
export function getWeather(city: string) {
return `The weather in ${city} is sunny.`;
}
// you don't need to worry about the shcema with different llm tools
export function getTemperature(city: string) {
return `The temperature in ${city} is 25°C.`;
}
export function getCurrentCity() {
return "New York";
}
```
These functions can be easily integrated into your applications, such as Next.js:
```ts
"use server";
import { OpenAI } from "openai";
import { getTools } from "@llamaindex/tool";
export async function chat(message: string) {
const openai = new OpenAI();
openai.chat.completions.create({
messages: [
{
role: "user",
content: "What is the weather in the current city?",
},
],
tools: getTools("openai"),
});
}
```
```ts
// next.config.js
const withTool = require("@llamaindex/tool/next");
const config = {
// Your original Next.js config
};
module.exports = withTool(config);
```
The functions are automatically transformed into tools for the agent at compile time, which eliminates any extra runtime
costs. This feature is particularly beneficial when you need to debug or deploy your assistant.
For deploying your local functions into OpenAI, you can use a simple command:
```sh
npm install -g @llamaindex/tool
mkai --tools ./src/index.llama.ts
# Successfully created assistant: asst_XXX
# chat with your assistant by `chatai --assistant asst_XXX`
chatai --assistant asst_XXX
# Open your browser and chat with your assistant
# Running at http://localhost:3000
```
This deployment process simplifies the testing and implementation of your custom tools in a live environment.
As this project is still in its early stages, we continue to explore the best ways to create and integrate tools for
agents. For more information and updates, visit the @llamaindex/tool repository.
This release of LlamaIndexTS v0.3.0 marks a significant step forward in our journey to provide developers with robust,
flexible tools for building advanced agents. We are excited to see how our community utilizes these new capabilities to
create innovative solutions and look forward to continuing to support and enhance LlamaIndexTS in future updates.

# Local LLMs
LlamaIndex.TS supports OpenAI and [other remote LLM APIs](other_llms). You can also run a local LLM on your machine!
## Using a local model via Ollama
The easiest way to run a local LLM is via the great work of our friends at [Ollama](https://ollama.com/), who provide a simple to use client that will download, install and run a [growing range of models](https://ollama.com/library) for you.
### Install Ollama
They provide a one-click installer for Mac, Linux and Windows on their [home page](https://ollama.com/).
### Pick and run a model
Since we're going to be doing agentic work, we'll need a very capable model, but the largest models are hard to run on a laptop. We think `mixtral 8x7b` is a good balance between power and resources, but `llama3` is another great option. You can run Mixtral by running
```bash
ollama run mixtral:8x7b
```
The first time you run it will also automatically download and install the model for you.
### Switch the LLM in your code
To tell LlamaIndex to use a local LLM, use the `Settings` object:
```javascript
Settings.llm = new Ollama({
model: "mixtral:8x7b",
});
```
### Use local embeddings
If you're doing retrieval-augmented generation, LlamaIndex.TS will also call out to OpenAI to index and embed your data. To be entirely local, you can use a local embedding model like this:
```javascript
Settings.embedModel = new HuggingFaceEmbedding({
modelType: "BAAI/bge-small-en-v1.5",
quantized: false,
});
```
The first time this runs it will download the embedding model to run it.
### Try it out
With a local LLM and local embeddings in place, you can perform RAG as usual and everything will happen on your machine without calling an API:
```typescript
async function main() {
// Load essay from abramov.txt in Node
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 response = await queryEngine.query({
query: "What did the author do in college?",
});
// Output response
console.log(response.toString());
}
main().catch(console.error);
```

# Using other LLM APIs
By default LlamaIndex.TS uses OpenAI's LLMs and embedding models, but we support [lots of other LLMs](../modules/llms) including models from Mistral (Mistral, Mixtral), Anthropic (Claude) and Google (Gemini).
If you don't want to use an API at all you can [run a local model](../../examples/local_llm)
## Using another LLM
You can specify what LLM LlamaIndex.TS will use on the `Settings` object, like this:
```typescript
import { MistralAI, Settings } from "llamaindex";
Settings.llm = new MistralAI({
model: "mistral-tiny",
apiKey: "<YOUR_API_KEY>",
});
```
You can see examples of other APIs we support by checking out "Available LLMs" in the sidebar of our [LLMs section](../modules/llms).
## Using another embedding model
A frequent gotcha when trying to use a different API as your LLM is that LlamaIndex will also by default index and embed your data using OpenAI's embeddings. To completely switch away from OpenAI you will need to set your embedding model as well, for example:
```typescript
import { MistralAIEmbedding, Settings } from "llamaindex";
Settings.embedModel = new MistralAIEmbedding();
```
We support [many different embeddings](../modules/embeddings).
## Full example
This example uses Mistral's `mistral-tiny` model as the LLM and Mistral for embeddings as well.

To use OpenAI, you'll need to [get an OpenAI API key](https://platform.openai.com/account/api-keys) and then make it available as an environment variable this way:
Our examples use OpenAI by default. You'll need to set up your Open AI key like so:

# Chatbot tutorial
Once you've mastered basic [retrieval-augment generation](retrieval_augmented_generation) you may want to create an interface to chat with your data. You can do this step-by-step, but we recommend getting started quickly using `create-llama`.
## Using create-llama
`create-llama` is a powerful but easy to use command-line tool that generates a working, full-stack web application that allows you to chat with your data. You can learn more about it on [the `create-llama` README page](https://www.npmjs.com/package/create-llama).
Run it once and it will ask you a series of questions about the kind of application you want to generate. Then you can customize your application to suit your use-case. To get started, run:
```bash npm2yarn
npx create-llama@latest
```
Once your app is generated, `cd` into your app directory and run
```bash npm2yarn
npm run dev
```
to start the development server. You can then visit [http://localhost:3000](http://localhost:3000) to see your app, which should look something like this:

# Retrieval Augmented Generation (RAG) Tutorial
One of the most common use-cases for LlamaIndex is Retrieval-Augmented Generation or RAG, in which your data is indexed and selectively retrieved to be given to an LLM as source material for responding to a query. You can learn more about the [concepts behind RAG](../concepts).
## Set up the project
In a new folder, run:
```bash npm2yarn
npm init
npm install -D typescript @types/node

Then, check out the [installation](../installation) steps to install LlamaIndex.TS and prepare an OpenAI key.
You can use [other LLMs](../examples/other_llms) via their APIs; if you would prefer to use local models check out our [local LLM example](../../examples/local_llm).
## Run queries
Create the file `example.ts`. This code will
- load an example file
- convert it into a Document object
- index it (which creates embeddings using OpenAI)
- create a query engine to answer questions about the data

Create a `tsconfig.json` file in the same folder:
<CodeBlock language="json">{TSConfigSource}</CodeBlock>
Now you can run the code with
```bash
npx tsx example.ts
```
You should expect output something like:

Ultimately, the author lost motivation for college due to their job as a software developer and stopped attending classes, only returning years later to pick up their papers.

# Structured data extraction tutorial
Make sure you have installed LlamaIndex.TS and have an OpenAI key. If you haven't, check out the [installation](installation) guide.
You can use [other LLMs](../examples/other_llms) via their APIs; if you would prefer to use local models check out our [local LLM example](../../examples/local_llm).
## Set up
In a new folder:
```bash npm2yarn
npm init
npm install -D typescript @types/node
```
## Extract data
Create the file `example.ts`. This code will:
- Set up an LLM connection to GPT-4
- Give an example of the data structure we wish to generate
- Prompt the LLM with instructions and the example, plus a sample transcript
<CodeBlock language="ts">{CodeSource}</CodeBlock>
To run the code:
```bash
npx tsx example.ts
```
You should expect output something like:
```json
{
"summary": "Sarah from XYZ Company called John to introduce the XYZ Widget, a tool designed to automate tasks and improve productivity. John expressed interest and requested case studies and a product demo. Sarah agreed to send the information and follow up to schedule the demo.",
"products": ["XYZ Widget"],
"rep_name": "Sarah",
"prospect_name": "John",
"action_items": [
"Send case studies and additional product information to John",
"Follow up with John to schedule a product demo"
]

# Getting started
In this guide we'll walk you through the process of building an Agent in JavaScript using the LlamaIndex.TS library, starting from nothing and adding complexity in stages.
## What is an Agent?
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.
![agent flow](./images/agent_flow.png)
## Install LlamaIndex.TS
You'll need to have a recent version of [Node.js](https://nodejs.org/en) installed. Then you can install LlamaIndex.TS by running
```bash
npm install llamaindex
```
## Choose your model
By default we'll be using OpenAI with GPT-4, as it's a powerful model and easy to get started with. If you'd prefer to run a local model, see [using a local model](local_model).
## Get an OpenAI API key
If you don't already have one, you can sign up for an [OpenAI API key](https://platform.openai.com/api-keys). You should then put the key in a `.env` file in the root of the project; the file should look like
```
OPENAI_API_KEY=sk-XXXXXXXXXXXXXXXXXXXXXXXX
```
We'll use `dotenv` to pull the API key out of that .env file, so also run:
```bash
npm install dotenv
```
Now you're ready to [create your agent](create_agent).

# Create a basic agent
We want to use `await` so we're going to wrap all of our code in a `main` function, like this:
```typescript
// Your imports go here
async function main() {
// the rest of your code goes here
}
main().catch(console.error);
```
For the rest of this guide we'll assume your code is wrapped like this so we can use `await`. You can run the code this way:
```bash
npx tsx example.ts
```
### Load your dependencies
First we'll need to pull in our dependencies. These are:
- The OpenAI class to use the OpenAI LLM
- FunctionTool to provide tools to our agent
- OpenAIAgent to create the agent itself
- Settings to define some global settings for the library
- Dotenv to load our API key from the .env file
```javascript
import { OpenAI, FunctionTool, OpenAIAgent, Settings } from "llamaindex";
import "dotenv/config";
```
### Initialize your LLM
We need to tell our OpenAI class where its API key is, and which of OpenAI's models to use. We'll be using `gpt-4o`, which is capable while still being pretty cheap. This is a global setting, so anywhere an LLM is needed will use the same model.
```javascript
Settings.llm = new OpenAI({
apiKey: process.env.OPENAI_API_KEY,
model: "gpt-4o",
});
```
### Turn on logging
We want to see what our agent is up to, so we're going to hook into some events that the library generates and print them out. There are several events possible, but we'll specifically tune in to `llm-tool-call` (when a tool is called) and `llm-tool-result` (when it responds).
```javascript
Settings.callbackManager.on("llm-tool-call", (event) => {
console.log(event.detail.payload);
});
Settings.callbackManager.on("llm-tool-result", (event) => {
console.log(event.detail.payload);
});
```
### Create a function
We're going to create a very simple function that adds two numbers together. This will be the tool we ask our agent to use.
```javascript
const sumNumbers = ({ a, b }) => {
return `${a + b}`;
};
```
Note that we're passing in an object with two named parameters, `a` and `b`. This is a little unusual, but important for defining a tool that an LLM can use.
### Turn the function into a tool for the agent
This is the most complicated part of creating an agent. We need to define a `FunctionTool`. We have to pass in:
- The function itself (`sumNumbers`)
- A name for the function, which the LLM will use to call it
- A description of the function. The LLM will read this description to figure out what the tool does, and if it needs to call it
- A schema for function. We tell the LLM that the parameter is an `object`, and we tell it about the two named parameters we gave it, `a` and `b`. We describe each parameter as a `number`, and we say that both are required.
- You can see [more examples of function schemas](https://cookbook.openai.com/examples/how_to_call_functions_with_chat_models).
```javascript
const tool = FunctionTool.from(sumNumbers, {
name: "sumNumbers",
description: "Use this function to sum two numbers",
parameters: {
type: "object",
properties: {
a: {
type: "number",
description: "First number to sum",
},
b: {
type: "number",
description: "Second number to sum",
},
},
required: ["a", "b"],
},
});
```
We then wrap up the tools into an array. We could provide lots of tools this way, but for this example we're just using the one.
```javascript
const tools = [tool];
```
### Create the agent
With your LLM already set up and your tools defined, creating an agent is simple:
```javascript
const agent = new OpenAIAgent({ tools });
```
### Ask the agent a question
We can use the `chat` interface to ask our agent a question, and it will use the tools we've defined to find an answer.
```javascript
let response = await agent.chat({
message: "Add 101 and 303",
});
console.log(response);
```
Let's see what running this looks like using `npx tsx agent.ts`
**_Output_**
```javascript
{
toolCall: {
id: 'call_ze6A8C3mOUBG4zmXO8Z4CPB5',
name: 'sumNumbers',
input: { a: 101, b: 303 }
},
toolResult: {
tool: FunctionTool { _fn: [Function: sumNumbers], _metadata: [Object] },
input: { a: 101, b: 303 },
output: '404',
isError: false
}
}
```
```javascript
{
response: {
raw: {
id: 'chatcmpl-9KwauZku3QOvH78MNvxJs81mDvQYK',
object: 'chat.completion',
created: 1714778824,
model: 'gpt-4-turbo-2024-04-09',
choices: [Array],
usage: [Object],
system_fingerprint: 'fp_ea6eb70039'
},
message: {
content: 'The sum of 101 and 303 is 404.',
role: 'assistant',
options: {}
}
},
sources: [Getter]
}
```
We're seeing two pieces of output here. The first is our callback firing when the tool is called. You can see in `toolResult` that the LLM has correctly passed `101` and `303` to our `sumNumbers` function, which adds them up and returns `404`.
The second piece of output is the response from the LLM itself, where the `message.content` key is giving us the answer.
Great! We've built an agent with tool use! Next you can:
- [See the full code](https://github.com/run-llama/ts-agents/blob/main/1_agent/agent.ts)
- [Switch to a local LLM](local_model)
- Move on to [add Retrieval-Augmented Generation to your agent](agentic_rag)

# Using a local model via Ollama
If you're happy using OpenAI, you can skip this section, but many people are interested in using models they run themselves. The easiest way to do this is via the great work of our friends at [Ollama](https://ollama.com/), who provide a simple to use client that will download, install and run a [growing range of models](https://ollama.com/library) for you.
### Install Ollama
They provide a one-click installer for Mac, Linux and Windows on their [home page](https://ollama.com/).
### Pick and run a model
Since we're going to be doing agentic work, we'll need a very capable model, but the largest models are hard to run on a laptop. We think `mixtral 8x7b` is a good balance between power and resources, but `llama3` is another great option. You can run it simply by running
```bash
ollama run mixtral:8x7b
```
The first time you run it will also automatically download and install the model for you.
### Switch the LLM in your code
There are two changes you need to make to the code we already wrote in `1_agent` to get Mixtral 8x7b to work. First, you need to switch to that model. Replace the call to `Settings.llm` with this:
```javascript
Settings.llm = new Ollama({
model: "mixtral:8x7b",
});
```
### Swap to a ReActAgent
In our original code we used a specific OpenAIAgent, so we'll need to switch to a more generic agent pattern, the ReAct pattern. This is simple: change the `const agent` line in your code to read
```javascript
const agent = new ReActAgent({ tools });
```
(You will also need to bring in `Ollama` and `ReActAgent` in your imports)
### Run your totally local agent
Because your embeddings were already local, your agent can now run entirely locally without making any API calls.
```bash
node agent.mjs
```
Note that your model will probably run a lot slower than OpenAI, so be prepared to wait a while!
**_Output_**
```javascript
{
response: {
message: {
role: 'assistant',
content: ' Thought: I need to use a tool to add the numbers 101 and 303.\n' +
'Action: sumNumbers\n' +
'Action Input: {"a": 101, "b": 303}\n' +
'\n' +
'Observation: 404\n' +
'\n' +
'Thought: I can answer without using any more tools.\n' +
'Answer: The sum of 101 and 303 is 404.'
},
raw: {
model: 'mixtral:8x7b',
created_at: '2024-05-09T00:24:30.339473Z',
message: [Object],
done: true,
total_duration: 64678371209,
load_duration: 57394551334,
prompt_eval_count: 475,
prompt_eval_duration: 4163981000,
eval_count: 94,
eval_duration: 3116692000
}
},
sources: [Getter]
}
```
Tada! You can see all of this in the folder `1a_mixtral`.
### Extending to other examples
You can use a ReActAgent instead of an OpenAIAgent in any of the further examples below, but keep in mind that GPT-4 is a lot more capable than Mixtral 8x7b, so you may see more errors or failures in reasoning if you are using an entirely local setup.
### Next steps
Now you've got a local agent, you can [add Retrieval-Augmented Generation to your agent](agentic_rag).

# Adding Retrieval-Augmented Generation (RAG)
While an agent that can perform math is nifty (LLMs are usually not very good at math), LLM-based applications are always more interesting when they work with large amounts of data. In this case, we're going to use a 200-page PDF of the proposed budget of the city of San Francisco for fiscal years 2024-2024 and 2024-2025. It's a great example because it's extremely wordy and full of tables of figures, which present a challenge for humans and LLMs alike.
To learn more about RAG, we recommend this [introduction](https://docs.llamaindex.ai/en/stable/getting_started/concepts/) from our Python docs. We'll assume you know the basics:
- You need to parse your source data into chunks of text
- You need to encode that text as numbers, called embeddings
- You need to search your embeddings for the most relevant chunks of text
- You feed your relevant chunks and a query to an LLM to answer a question
We're going to start with the same agent we [built in step 1](https://github.com/run-llama/ts-agents/blob/main/1_agent/agent.ts), but make a few changes. You can find the finished version [in the repository](https://github.com/run-llama/ts-agents/blob/main/2_agentic_rag/agent.ts).
### New dependencies
We'll be bringing in `SimpleDirectoryReader`, `HuggingFaceEmbedding`, `VectorStoreIndex`, and `QueryEngineTool` from LlamaIndex.TS, as well as the dependencies we previously used.
```javascript
import {
OpenAI,
FunctionTool,
OpenAIAgent,
Settings,
SimpleDirectoryReader,
HuggingFaceEmbedding,
VectorStoreIndex,
QueryEngineTool,
} from "llamaindex";
```
### Add an embedding model
To encode our text into embeddings, we'll need an embedding model. We could use OpenAI for this but to save on API calls we're going to use a local embedding model from HuggingFace.
```javascript
Settings.embedModel = new HuggingFaceEmbedding({
modelType: "BAAI/bge-small-en-v1.5",
quantized: false,
});
```
### Load data using SimpleDirectoryReader
SimpleDirectoryReader is a flexible tool that can read a variety of file formats. We're going to point it at our data directory, which contains just the single PDF file, and get it to return a set of documents.
```javascript
const reader = new SimpleDirectoryReader();
const documents = await reader.loadData("../data");
```
### Index our data
Now we turn our text into embeddings. The `VectorStoreIndex` class takes care of this for us when we use the `fromDocuments` method (it uses the embedding model we defined in `Settings` earlier).
```javascript
const index = await VectorStoreIndex.fromDocuments(documents);
```
### Configure a retriever
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
```javascript
const retriever = await index.asRetriever();
```
### Configure how many documents to retrieve
By default LlamaIndex will retrieve just the 2 most relevant chunks of text. This document is complex though, so we'll ask for more context.
```javascript
retriever.similarityTopK = 10;
```
### Create a query engine
And our final step in creating a RAG pipeline is to create a query engine that will use the retriever to find the most relevant chunks of text, and then use the LLM to answer the question.
```javascript
const queryEngine = await index.asQueryEngine({
retriever,
});
```
### Define the query engine as a tool
Just as before we created a `FunctionTool`, we're going to create a `QueryEngineTool` that uses our `queryEngine`.
```javascript
const tools = [
new QueryEngineTool({
queryEngine: queryEngine,
metadata: {
name: "san_francisco_budget_tool",
description: `This tool can answer detailed questions about the individual components of the budget of San Francisco in 2023-2024.`,
},
}),
];
```
As before, we've created an array of tools with just one tool in it. The metadata is slightly different: we don't need to define our parameters, we just give the tool a name and a natural-language description.
### Create the agent as before
Creating the agent and asking a question is exactly the same as before, but we'll ask a different question.
```javascript
// create the agent
const agent = new OpenAIAgent({ tools });
let response = await agent.chat({
message: "What's the budget of San Francisco in 2023-2024?",
});
console.log(response);
```
Once again we'll run `npx tsx agent.ts` and see what we get:
**_Output_**
```javascript

toolCall: {
id: 'call_iNo6rTK4pOpOBbO8FanfWLI9',

For FY 2024-25, the total budget is also projected to be $14.6 billion, reflecting a $40.5 million, or 0.3 percent, decrease from the FY 2023-24 proposed budget. This budget includes various expenditures across different departments and services, with significant allocations to public works, transportation, commerce, public protection, and health services.',

}
}

}
},

Once again we see a `toolResult`. You can see the query the LLM decided to send to the query engine ("total budget"), and the output the engine returned. In `response.message` you see that the LLM has returned the output from the tool almost verbatim, although it trimmed out the bit about 2024-2025 since we didn't ask about that year.
So now we have an agent that can index complicated documents and answer questions about them. Let's [combine our math agent and our RAG agent](rag_and_tools)!

# A RAG agent that does math
In [our third iteration of the agent](https://github.com/run-llama/ts-agents/blob/main/3_rag_and_tools/agent.ts) we've combined the two previous agents, so we've defined both `sumNumbers` and a `QueryEngineTool` and created an array of two tools:
```javascript
// define the query engine as a tool
const tools = [
new QueryEngineTool({
queryEngine: queryEngine,
metadata: {
name: "san_francisco_budget_tool",
description: `This tool can answer detailed questions about the individual components of the budget of San Francisco in 2023-2024.`,
},
}),
FunctionTool.from(sumNumbers, {
name: "sumNumbers",
description: "Use this function to sum two numbers",
parameters: {
type: "object",
properties: {
a: {
type: "number",
description: "First number to sum",
},
b: {
type: "number",
description: "Second number to sum",
},
},
required: ["a", "b"],
},
}),
];
```
These tool descriptions are identical to the ones we previously defined. Now let's ask it 3 questions in a row:
```javascript
let response = await agent.chat({
message:
"What's the budget of San Francisco for community health in 2023-24?",
});
console.log(response);
let response2 = await agent.chat({
message:
"What's the budget of San Francisco for public protection in 2023-24?",
});
console.log(response2);
let response3 = await agent.chat({
message:
"What's the combined budget of San Francisco for community health and public protection in 2023-24?",
});
console.log(response3);
```
We'll abbreviate the output, but here are the important things to spot:
```javascript
{
toolCall: {
id: 'call_ZA1LPx03gO4ABre1r6XowLWq',
name: 'san_francisco_budget_tool',
input: { query: 'community health budget 2023-2024' }
},
toolResult: {
tool: QueryEngineTool {
queryEngine: [RetrieverQueryEngine],
metadata: [Object]
},
input: { query: 'community health budget 2023-2024' },
output: 'The proposed Fiscal Year (FY) 2023-24 budget for the Department of Public Health is $3.2 billion
}
}
```
This is the first tool call, where it used the query engine to get the public health budget.
```javascript
{
toolCall: {
id: 'call_oHu1KjEvA47ER6HYVfFIq9yp',
name: 'san_francisco_budget_tool',
input: { query: 'public protection budget 2023-2024' }
},
toolResult: {
tool: QueryEngineTool {
queryEngine: [RetrieverQueryEngine],
metadata: [Object]
},
input: { query: 'public protection budget 2023-2024' },
output: "The budget for Public Protection in San Francisco for Fiscal Year (FY) 2023-24 is $2,012.5 million."
}
}
```
In the second tool call, it got the police budget also from the query engine.
```javascript
{
toolCall: {
id: 'call_SzG4yGUnLbv1T7IyaLAOqg3t',
name: 'sumNumbers',
input: { a: 3200, b: 2012.5 }
},
toolResult: {
tool: FunctionTool { _fn: [Function: sumNumbers], _metadata: [Object] },
input: { a: 3200, b: 2012.5 },
output: '5212.5',
isError: false
}
}
```
In the final tool call, it used the `sumNumbers` function to add the two budgets together. Perfect! This leads to the final answer:
```javascript
{
message: {
content: 'The combined budget of San Francisco for community health and public protection in Fiscal Year (FY) 2023-24 is $5,212.5 million.',
role: 'assistant',

}
}

Great! Now let's improve accuracy by improving our parsing with [LlamaParse](llamaparse).

# Adding LlamaParse
Complicated PDFs can be very tricky for LLMs to understand. To help with this, LlamaIndex provides LlamaParse, a hosted service that parses complex documents including PDFs. To use it, get a `LLAMA_CLOUD_API_KEY` by [signing up for LlamaCloud](https://cloud.llamaindex.ai/) (it's free for up to 1000 pages/day) and adding it to your `.env` file just as you did for your OpenAI key:
```bash
LLAMA_CLOUD_API_KEY=llx-XXXXXXXXXXXXXXXX

Then replace `SimpleDirectoryReader` with `LlamaParseReader`:
```javascript
const reader = new LlamaParseReader({ resultType: "markdown" });
const documents = await reader.loadData("../data/sf_budget_2023_2024.pdf");

Now you will be able to ask more complicated questions of the same PDF and get better results. You can find this code [in our repo](https://github.com/run-llama/ts-agents/blob/main/4_llamaparse/agent.ts).
Next up, let's persist our embedded data so we don't have to re-parse every time by [using a vector store](qdrant).

# Adding persistent vector storage
In the previous examples, we've been loading our data into memory each time we run the agent. This is fine for small datasets, but for larger datasets you'll want to store your embeddings in a database. LlamaIndex.TS provides a `VectorStore` class that can store your embeddings in a variety of databases. We're going to use [Qdrant](https://qdrant.tech/), a popular vector store, for this example.
We can get a local instance of Qdrant running very simply with Docker (make sure you [install Docker](https://www.docker.com/products/docker-desktop/) first):
```bash
docker pull qdrant/qdrant
docker run -p 6333:6333 qdrant/qdrant
```
And in our code we initialize a `VectorStore` with the Qdrant URL:
```javascript
// initialize qdrant vector store
const vectorStore = new QdrantVectorStore({
url: "http://localhost:6333",
});
```
Now once we have loaded our documents, we can instantiate an index with the vector store:
```javascript
// create a query engine from our documents
const index = await VectorStoreIndex.fromDocuments(documents, { vectorStore });
```
In [the final iteration](https://github.com/run-llama/ts-agents/blob/main/5_qdrant/agent.ts) you can see that we have also implemented a very naive caching mechanism to avoid re-parsing the PDF each time we run the agent:
```javascript
// load cache.json and parse it
let cache = {};
let cacheExists = false;
try {
await fs.access(PARSING_CACHE, fs.constants.F_OK);
cacheExists = true;
} catch (e) {
console.log("No cache found");
}
if (cacheExists) {
cache = JSON.parse(await fs.readFile(PARSING_CACHE, "utf-8"));
}
const filesToParse = ["../data/sf_budget_2023_2024.pdf"];
// load our data, reading only files we haven't seen before
let documents = [];
const reader = new LlamaParseReader({ resultType: "markdown" });
for (let file of filesToParse) {
if (!cache[file]) {
documents = documents.concat(await reader.loadData(file));
cache[file] = true;
}
}
// write the cache back to disk
await fs.writeFile(PARSING_CACHE, JSON.stringify(cache));
```
Since parsing a PDF can be slow, especially a large one, using the pre-parsed chunks in Qdrant can significantly speed up your agent.

# What is LlamaIndex?
# What is LlamaIndex.TS?
LlamaIndex is a framework for building LLM-powered applications. LlamaIndex helps you ingest, structure, and access private or domain-specific data. It's available [as a Python package](https://docs.llamaindex.ai/en/stable/) and in TypeScript (this package). LlamaIndex.TS offers the core features of LlamaIndex for popular runtimes like Node.js (official support), Vercel Edge Functions (experimental), and Deno (experimental).
LlamaIndex.TS is a data framework for LLM applications to ingest, structure, and access private or domain-specific data. While a python package is also available (see [here](https://docs.llamaindex.ai/en/stable/)), LlamaIndex.TS offers core features in a simple package, optimized for usage with TypeScript.
## 🚀 Why LlamaIndex.TS?
LLMs offer a natural language interface between humans and inferred data. Widely available models come pre-trained on huge amounts of publicly available data, from Wikipedia and mailing lists to textbooks and source code.
At their core, LLMs offer a natural language interface between humans and inferred data. Widely available models come pre-trained on huge amounts of publicly available data, from Wikipedia and mailing lists to textbooks and source code.
Applications built on top of LLMs often require augmenting these models with private or domain-specific data. That data is often distributed across siloed applications and data stores. It's behind APIs, in SQL databases, or trapped in PDFs and slide decks.
Applications built on top of LLMs often require augmenting these models with private or domain-specific data. Unfortunately, that data can be distributed across siloed applications and data stores. It's behind APIs, in SQL databases, or trapped in PDFs and slide decks.
LlamaIndex.TS helps you unlock that data and then build powerful applications with it.
That's where **LlamaIndex.TS** comes in.
## 🦙 What is LlamaIndex for?
## 🦙 How can LlamaIndex.TS help?
LlamaIndex.TS handles several major use cases:
LlamaIndex.TS provides the following tools:
- **Structured Data Extraction**: turning complex, unstructured and semi-structured data into uniform, programmatically accessible formats.
- **Retrieval-Augmented Generation (RAG)**: answering queries across your internal data by providing LLMs with up-to-date, semantically relevant context including Question and Answer systems and chat bots.
- **Autonomous Agents**: building software that is capable of intelligently selecting and using tools to accomplish tasks in an interative, unsupervised manner.
- **Data loading** ingest your existing `.txt`, `.pdf`, `.csv`, `.md` and `.docx` data directly
- **Data indexes** structure your data in intermediate representations that are easy and performant for LLMs to consume.
- **Engines** provide natural language access to your data. For example:
- Query engines are powerful retrieval interfaces for knowledge-augmented output.
- Chat engines are conversational interfaces for multi-message, "back and forth" interactions with your data.
## 👨‍👩‍👧‍👦 Who is LlamaIndex for?
LlamaIndex targets the "AI Engineer": developers building software in any domain that can be enhanced by LLM-powered functionality, without needing to be an expert in machine learning or natural language processing.
LlamaIndex.TS provides a core set of tools, essential for anyone building LLM apps with JavaScript and TypeScript.
Our high-level API allows beginner users to use LlamaIndex.TS to ingest, index, and query their data in just a few lines of code.

LlamaParse is an API created by LlamaIndex to efficiently parse files, e.g. it's great at converting PDF tables into markdown.
To use it, first login and get an API key from https://cloud.llamaindex.ai. Make sure to store the key as `apiKey` parameter or in the environment variable `LLAMA_CLOUD_API_KEY`.
To use it, first login and get an API key from https://cloud.llamaindex.ai. Make sure to store the key in the environment variable `LLAMA_CLOUD_API_KEY`.
Then, you can use the `LlamaParseReader` class to local files and convert them into a parsed document that can be used by LlamaIndex.
See [LlamaParseReader.ts](https://github.com/run-llama/LlamaIndexTS/blob/main/packages/core/src/readers/LlamaParseReader.ts#L6) for a list of supported file types:
Then, you can use the `LlamaParseReader` class to read a local PDF file and convert it into a markdown document that can be used by LlamaIndex:

Additional options can be set with the `LlamaParseReader` constructor:
- `resultType` can be set to `markdown`, `text` or `.json`. Defaults to `text`
- `language` primarly helps with OCR recognition. Defaults to `en`. See [../readers/type.ts](https://github.com/run-llama/LlamaIndexTS/blob/main/packages/core/src/readers/type.ts#L20) for a list of supported languages.
- `parsingInstructions` can help with complicated document structures. See this [LlamaIndex Blog Post](https://www.llamaindex.ai/blog/launching-the-first-genai-native-document-parsing-platform) for an example.
- `skipDiagonalText` set to true to ignore diagonal text.
- `invalidateCache` set to true to ignore the LlamaCloud cache. All document are kept in cache for 48hours after the job was completed to avoid processing the same document twice. Can be useful for testing when trying to re-parse the same document with, e.g. different `parsingInstructions`.
- `gpt4oMode` set to true to use GPT-4o to extract content.
- `gpt4oApiKey` set the GPT-4o API key. Optional. Lowers the cost of parsing by using your own API key. Your OpenAI account will be charged. Can also be set in the environment variable `LLAMA_CLOUD_GPT4O_API_KEY`.
- `numWorkers` as in the python version, is set in `SimpleDirectoryReader`. Default is 1.

# DeepInfra
To use DeepInfra embeddings, you need to import `DeepInfraEmbedding` from llamaindex.
Check out available embedding models [here](https://deepinfra.com/models/embeddings).
```ts
import {
DeepInfraEmbedding,
Settings,
Document,
VectorStoreIndex,
} from "llamaindex";
// Update Embed Model
Settings.embedModel = new DeepInfraEmbedding();
const document = new Document({ text: essay, id_: "essay" });
const index = await VectorStoreIndex.fromDocuments([document]);
const queryEngine = index.asQueryEngine();
const query = "What is the meaning of life?";
const results = await queryEngine.query({
query,
});
```
By default, DeepInfraEmbedding is using the sentence-transformers/clip-ViT-B-32 model. You can change the model by passing the model parameter to the constructor.
For example:
```ts
import { DeepInfraEmbedding } from "llamaindex";
const model = "intfloat/e5-large-v2";
Settings.embedModel = new DeepInfraEmbedding({
model,
});
```
You can also set the `maxRetries` and `timeout` parameters when initializing `DeepInfraEmbedding` for better control over the request behavior.
For example:
```ts
import { DeepInfraEmbedding, Settings } from "llamaindex";
const model = "intfloat/e5-large-v2";
const maxRetries = 5;
const timeout = 5000; // 5 seconds
Settings.embedModel = new DeepInfraEmbedding({
model,
maxRetries,
timeout,
});
```
Standalone usage:
```ts
import { DeepInfraEmbedding } from "llamaindex";
import { config } from "dotenv";
// For standalone usage, you need to configure DEEPINFRA_API_TOKEN in .env file
config();
const main = async () => {
const model = "intfloat/e5-large-v2";
const embeddings = new DeepInfraEmbedding({ model });
const text = "What is the meaning of life?";
const response = await embeddings.embed([text]);
console.log(response);
};

### Usage with Vertex AI
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, GeminiVertexSession } from "llamaindex";
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 install @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.
## 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.

# Jina AI Reranker
The Jina AI Reranker is a postprocessor that uses the Jina AI Reranker API to rerank the results of a search query.
## Setup
Firstly, you will need to install the `llamaindex` package.
```bash
pnpm install llamaindex
```
Now, you will need to sign up for an API key at [Jina AI](https://jina.ai/reranker). Once you have your API key you can import the necessary modules and create a new instance of the `JinaAIReranker` class.
```ts
import {
JinaAIReranker,
Document,
OpenAI,
VectorStoreIndex,
Settings,
} from "llamaindex";
```
## 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" });
Settings.llm = new OpenAI({ model: "gpt-3.5-turbo", temperature: 0.1 });
const index = await VectorStoreIndex.fromDocuments([document]);
```
## Increase similarity topK to retrieve more results
The default value for `similarityTopK` is 2. This means that only the most similar document will be returned. To retrieve more results, you can increase the value of `similarityTopK`.
```ts
const retriever = index.asRetriever();
retriever.similarityTopK = 5;
```
## Create a new instance of the JinaAIReranker class
Then you can create a new instance of the `JinaAIReranker` class and pass in the number of results you want to return.
The Jina AI Reranker API key is set in the `JINAAI_API_KEY` environment variable.
```bash
export JINAAI_API_KEY=<YOUR API KEY>
```
```ts
const nodePostprocessor = new JinaAIReranker({
topN: 5,
});
```
## Create a query engine with the retriever and node postprocessor
```ts
const queryEngine = index.asQueryEngine({
retriever,
nodePostprocessors: [nodePostprocessor],
});
// log the response
const response = await queryEngine.query("Where did the author grown up?");
