The Client SDK is intended to provide a ready solution for developers to build Programmable Conversation applications across multiple Channels including: Messages, Voice, SIP, websockets, and App.
⚠️ Warning: Chat Functionality (Beta)The chat functionality in our SDK is currently in beta. Methods related to chat may undergo changes as we refine and improve this feature. Please be aware of potential updates as we work towards its stability. Your feedback is valuable in shaping its development.
The SDK can be installed using the npm install command
npm i @vonage/client-sdkimport {
VonageClient,
ClientConfig,
ConfigRegion,
LoggingLevel
} from '@vonage/client-sdk';
import { useState, useEffect } from 'react';

const [client] = useState(() => {
// Initialize client with optional config (default: ERROR logging, US region).
const client = new VonageClient({
loggingLevel: LoggingLevel.DEBUG,
region: ConfigRegion.EU
});
// Or update some options after initialization.
client.setConfig(config);
return client;
});
const [session, setSession] = useState();
const [user, setUser] = useState();
const [error, setError] = useState();
// Create Session as soon as client is available
