useWebchat

The useWebchat hook provides access to the Webchat client and its state. It allows you to:

Interact with your bot
Listen to real-time events
Manage conversation lifecycle, user info, and messages

The useWebchat hook is incompatible with the batteries-included <Webchat> component—using them together will cause issues and unexpected behaviour.If you need to use the hook, make sure you’re manually building Webchat.

Usage

App.tsx

import { useWebchat } from '@botpress/webchat'

function App() {
  const { client, clientState, on, user, conversationId, newConversation, messages, isFetchingMessages, isTyping } =
    useWebchat({
      clientId: '$CLIENT_ID$', // Insert your Client ID here
    })
}

Parameters

string

Your Botpress project Client ID. Required to initialize the client and establish communication with the server.
