SDK setup

With bundler (Webpack, Vite, etc.) and React

import { VonageClient, ClientConfig, ConfigRegion } from '@vonage/client-sdk';
import { useState, useEffect } from 'react';

function App() {
  // Config is optional but recomended, default region is US
  const [config] = useState(() => new ClientConfig(ConfigRegion.US));
  const [client] = useState(() => {
    const client = new VonageClient();
    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
  useEffect(() => {
    if (!client) return;
    client
      .createSession('my-token')
      .then((session) => setSession(session))
      .catch((error) => setError(error));
  }, [client]);

  // Get User as soon as a session is available
  useEffect(() => {
    if (!client || !session) return;
    client
      .getUser('me')
      .then((user) => setUser(user))
      .catch((error) => setError(error));
  }, [client, session]);

  if (error) return <pre>{JSON.stringify(error)}</pre>;

  if (!session || !user) return <div>Loading...</div>;

  return <div>User {user.displayName || user.name} logged in</div>;
}

export default App;

With script tag (UMD)

  const token = 'my-token';
  const client = new vonageClientSDK.VoiceClient();
  const config = new vonageClientSDK.ClientConfig(

  );
  client.setConfig(config);

  client.createSession(token).then((Session) => {});
</script>

} from 'https://cdn.jsdelivr.net/npm/@vonage/client-sdk@1.0.0/dist/vonageClientSDK.esm.min.js';

const client = new VonageClient();

// Config is optional but recomended, default region is US

client.setConfig(config);

(async () => {
  const token = 'my-token';
  try {
    // Create Session
    const sessionId = await client.createSession(token);
    // Get User
    const user = await client.getUser('me');
    console.log(
      `User ${
        user.displayName || user.name
      } logged in with session ID: ${sessionId}`
    );
  } catch (error) {
