### Start Developing
You can launch the package in dev-mode by running:
```shell
pnpm dev

This will use turbo to run all packages in watch-mode. This means you can make changes and have them automatically built.
If you want to customize what packages are built/watched, you can run turbo directly and adjust the filter:
```shell
pnpm turbo run dev --filter="./packages/core" --concurrency=100
```
In another terminal, you can write and run any script needed to quickly test your changes. For example:
```typescript
import { createMemory, staticBlock } from "@llamaindex/core/memory";
// Create memory with predefined context
const memory = createMemory({
memoryBlocks: [
staticBlock({
content:
"The user is a software engineer who loves TypeScript and LlamaIndex.",
messageRole: "system",

],
});
async function main() {
const result = await memory.getLLM();
console.log(result);
}
void main().catch(console.error);
```
And run it with:
```shell
pnpm exec tsx my_script.ts

This flow allows you to easily test your changes without having to build the entire project.

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.

description: How to install llamaindex packages.
description: How to install and set up LlamaIndex.TS for your project.
---
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.

## 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.

title: Next.js Applications
description: Deploy LlamaIndex.TS in Next.js applications with API routes, server components, and edge runtime.
---
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)) {
controller.enqueue(new TextEncoder().encode(event.data.delta));
}
}
controller.close();
} catch (error) {
controller.error(error);
}
},
});
return new Response(stream, {
headers: {
"Content-Type": "text/plain",
"Transfer-Encoding": "chunked",
},
});
}
```
## 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 (
<div className="max-w-2xl mx-auto p-4">
<form onSubmit={handleSubmit} className="mb-4">

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

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');
});
});
```

try {
const { message } = request.body as { message: string };
const result = await myAgent.run(message);
return { response: result.data };
} catch (error) {
reply.status(500).send({ error: 'Chat failed' });
}
});
const start = async () => {
await initializeAgent();
await fastify.listen({ port: 3000 });
console.log('Server running on port 3000');
};
start();
```
### Hono
```typescript
import { Hono } from "hono";
import { agent } from "@llamaindex/workflow";
import { tool } from "llamaindex";
import { openai } from "@llamaindex/openai";

import { agentStreamEvent } from "@llamaindex/workflow";
app.post('/api/chat-stream', async (req, res) => {
const { message } = req.body;
res.writeHead(200, {
'Content-Type': 'text/plain',
'Transfer-Encoding': 'chunked',
});
try {
const events = myAgent.runStream(message);
for await (const event of events) {
if (agentStreamEvent.include(event)) {
res.write(event.data.delta);
}
}
res.end();
} catch (error) {
res.write('Error: ' + error.message);
res.end();
}
});

title: Troubleshooting
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);
```
## Debugging Tips
### Enable Debug Logging
```typescript
// Enable debug logging
process.env.DEBUG = "llamaindex:*";
// Or specific modules
process.env.DEBUG = "llamaindex:vector-store";
```
### Check Package Versions
```bash
npm list llamaindex
npm list @llamaindex/openai
```
### Test in Isolation
```typescript
// 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);
}
}
testBasic();
```

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"
},
}
```
We recommend using `bundler` or `nodenext`, but due to popularity of `node`, we still added support for it.
## 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 {
console.log(event); // other events
}
}
```
## Run TypeScript Script in Node.js
We recommend to use [tsx](https://www.npmjs.com/package/tsx) to run TypeScript script in Node.js.
```shell
node --import tsx ./my-script.ts

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, make sure you have a basic understanding of [Vite](https://vitejs.dev/).
## 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](/docs/llamaindex/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](/docs/llamaindex/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)](/docs/llamaindex/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](/docs/llamaindex/getting_started/concepts).

# 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/).
![architecture](/images/mcp_db_toolbox.png)
### 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);

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](/docs/llamaindex/modules/agents/workflows) steps
- Have precise control over message handling and tool execution
## 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.
## 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 { 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
- **`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

title: Memory
description: Manage conversation history and context with agents
---
## Concept
Memory is a core component of agentic systems. It allows you to store and retrieve information from the past.
In LlamaIndexTS, you can create memory by using the `createMemory` function. This function will return a `Memory` object, which you can then use to store and retrieve information.
As the agent runs, it will make calls to `add()` to store information, and `get()` to retrieve information.
## Usage
A `Memory` object has both short-term memory (i.e. a FIFO queue of messages) and optionally long-term memory (i.e. extracting information over time).
`get()` always returns all messages stored in the memory. The longer the agent runs, this will exceed the context window of the agent. To avoid this, the agent is using the `getLLM` method to get the last X messages that fit into the context window.
### Configuring Memory for an Agent
Here we're creating a memory with a static block (read more about [memory blocks](#long-term-memory)) that contains some information about the user.
```ts twoslash
import { openai } from "@llamaindex/openai";
import { agent } from "@llamaindex/workflow";
import { createMemory, staticBlock } from "llamaindex";
const llm = openai({ model: "gpt-4.1-mini" });
// Create memory with predefined context
const memory = createMemory({
memoryBlocks: [
staticBlock({
content:
"The user is a software engineer who loves TypeScript and LlamaIndex.",
}),
],
});
// Create an agent with the memory
const workflow = agent({
name: "assistant",
llm,
memory,
});
const result = await workflow.run("What is my name?");
console.log("Response:", result.data.result);
```
### Using Vercel format
You can also put messages in Vercel format directly to the memory:
```ts
await memory.add({
id: "1",
createdAt: new Date(),
role: "user",
content: "Hello!",
options: {
parts: [
{
type: "file",
data: "base64...",
mimeType: "image/png",
},
],
},
});
```
If you call `get`, messages are usually retrieved in the LlamaIndexTS format (type `ChatMessage`). If you specify the `type` parameter using `get`, you can return the messages in different formats. E.g.: using `type: "vercel"`, you can return the messages in Vercel format:
```ts
const messages = await memory.get({ type: "vercel" });
console.log(messages);
```
## Customizing Memory
### Short-Term Memory
The `Memory` object will store all the messages that are added to the `Memory` object. Unless you call `clear()`, no messages are removed from the memory. This is the short-term memory (usually you will store the memory of one user session there) which is augmented by the long-term memory.
Calling `getLLM` will retrieve messages from long-term memory and ensure that the given `tokenLimit` is not reached. These are the messages that you will sent to the LLM.
For initialization, you call `createMemory` with the following options:
- `tokenLimit`: Maximum tokens for memory retrieval using `getLLM` (default: 30000).
- `shortTermTokenLimitRatio`: Ratio of tokens for short-term vs long-term memory (default: 0.7)
- `customAdapters`: Custom message adapters for different message formats. LlamaIndex (`ChatMessageAdapter`) and Vercel (`VercelMessageAdapter`) are built-in adapters.
- `memoryBlocks`: Memory blocks for long-term storage, see [Long-Term Memory](#long-term-memory)
Example:
```ts
const memory = createMemory({
tokenLimit=40000,
shortTermTokenLimitRatio=0.5,
});
```
### Long-Term Memory
Long-term memory is represented as `Memory Block` objects. These objects contain information that are from previous user sessions or from the beginning of the current conversation. When memory is retrieved (by calling `getLLM`), the short-term and long-term memories are merged together within the given `tokenLimit`.
Currently, there are three predefined memory blocks:
- `staticBlock`: A memory block that stores a static piece of information.
- `factExtractionBlock`: A memory block that extracts facts from the chat history.
- `vectorBlock`: A memory block that stores and retrieves chat messages from a vector database using semantic similarity search. Messages are stored individually and retrieved based on their relevance to recent conversation context. Here we've passed in the `vectorStore` to use to store and retrieve the chat messages.
This sounds a bit complicated, but it's actually quite simple. Let's look at an example:
```ts
import { createMemory, factExtractionBlock, staticBlock, vectorBlock } from "llamaindex";
import { QdrantVectorStore } from "@llamaindex/qdrant";
import { OpenAIEmbedding } from "@llamaindex/openai";
const memoryBlocks= [
staticBlock({
content: "My name is Logan, and I live in Saskatoon. I work at LlamaIndex.",
}),
factExtractionBlock({
priority: 1,
llm: llm,
maxFacts: 50,
}),
vectorBlock({
vectorStore: new QdrantVectorStore({ url: "http://localhost:6333" }),
priority: 2,
}),
];
```
Here, we've setup three memory blocks:
- `staticBlock`: A static memory block that stores some core information about the user. This information will always be inserted into the memory. The type used is `MessageContent` to support multi-modal content.
- `factExtractionBlock`: An extracted memory block that will extract information from the chat history. Here we've passed in the `llm` to use to extract facts from the chat history, and set the `maxFacts` to 50. If the number of extracted facts exceeds this limit, the `maxFacts` will be automatically summarized and reduced to leave room for new information.
- `vectorBlock`: A vector memory block that will store in a vector database and retrieve them from there. Messages are stored individually and retrieved based on their relevance to recent conversation context. Here we've passed in the `vectorStore` to use to store and retrieve the chat messages.
You'll also notice that we've set the `priority` for the `factExtractionBlock` block. This is used to determine the handling when the memory blocks content (i.e. long-term memory) + short-term memory exceeds the token limit on the `Memory` object.
- `priority=0`: This block will always be kept in memory (`staticBlocks` always have priority 0.)
- `priority=1, 2, 3, etc`: This determines the order in which memory blocks are truncated when the memory exceeds the token limit, to help the overall short-term memory + long-term memory content be less than or equal to the `tokenLimit`.
Now, let's pass these blocks into the `createMemory` function:
```ts
const memory = createMemory({
tokenLimit: 40000,
memoryBlocks: memoryBlocks,
)
```
When memory is retrieved (using `getLLM`), the short-term and long-term memories are merged together. The `Memory` object will ensure that the short-term memory + long-term memory content is less than or equal to the `tokenLimit`. If it is longer, messages are retrieved in the following order:
1. StaticMemoryBlock (information always included)
2. LongTermMemoryBlock (depending on priority)
3. ShortTermMemoryBlock
4. Transient messages
The amount of short-term memory included is specified by the `shortTermTokenLimitRatio`. If it's set to `0.7`, 70% of the `tokenLimit` is used for short-term memory (not including the static memory block).
#### VectorBlock Configuration Options
The `vectorBlock` offers several configuration options to customize its behavior:
```ts
vectorBlock({
vectorStore: new QdrantVectorStore({ url: "http://localhost:6333" }),
priority: 2,
retrievalContextWindow: 5, // Number of recent messages to use for context when retrieving
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.
## Persistence with Snapshots
Save and restore memory state:
```ts twoslash
import { createMemory, loadMemory } from "llamaindex";
const memory = createMemory();
// Add some messages
await memory.add({ role: "user", content: "Hello!" });
// Create snapshot
const snapshot = memory.snapshot();
// Later, restore from the snapshot
const restoredMemory = loadMemory(snapshot);
```

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

## Using the `exec` method
Many LLMs do not natively support structured output, and often rely exclusively on prompt or context engineering.
In this sense, we proved you with an alternative for structured data extraction, using the `exec` method with `responseFormat`.
For example, you can, in a new folder, install our Anthropic integration and `zod` v3:
```package-install
npm init
npm i -D typescript @types/node
npm i @llamaindex/anthropic zod@3.25.76
```
And then try extracting data with this code:
<include cwd>../../examples/agents/tools/response-format-exec.ts</include>
The output should look like this:
```json
{
"title": "La Divina Commedia",
"author": "Dante Alighieri",
"year": 1321
}
```
