Overview
The @chainlit/react-client
package provides a set of React hooks as well as an API client to connect to your Chainlit application from any React application. The package includes hooks for managing chat sessions, messages, data, and interactions.
Installation
To install the package, run the following command in your project directory:
npm install @chainlit/react-client
This package use Recoil to manage its state. This means you will have to wrap your application in a recoil provider:
import React from 'react';
import ReactDOM from 'react-dom/client';
import { RecoilRoot } from 'recoil';
import { ChainlitAPI, ChainlitContext } from '@chainlit/react-client';
const CHAINLIT_SERVER_URL = 'http://localhost:8000';
const apiClient = new ChainlitAPI(CHAINLIT_SERVER_URL, 'webapp');
ReactDOM.createRoot(document.getElementById('root') as HTMLElement).render(
<React.StrictMode>
<ChainlitContext.Provider value={apiClient}>
<RecoilRoot>
<MyApp />
</RecoilRoot>
</ChainlitContext.Provider>
</React.StrictMode>
);

import { useChatSession } from '@chainlit/react-client';
const ChatComponent = () => {
const { connect, disconnect, chatProfile, setChatProfile } = useChatSession();
// Connect to the WebSocket server
useEffect(() => {
connect({
userEnv: {
/* user environment variables */
},
accessToken: 'Bearer YOUR_ACCESS_TOKEN' // Optional Chainlit auth token
});
return () => {
disconnect();
};
}, []);
// Rest of your component logic
};
useChatMessages
This hook provides access to the chat messages and the first user message.

import { useChatMessages } from '@chainlit/react-client';

<div>
{messages.map((message) => (
<p key={message.id}>{message.content}</p>

import { useChatData } from '@chainlit/react-client';
const ChatDataComponent = () => {
const { loading, connected, error } = useChatData();
// Use the data to render your component
if (loading) return <p>Loading...</p>;
if (error) return <p>Error connecting to chat...</p>;
if (!connected) return <p>Disconnected...</p>;
