@telnyx/react-client

React wrapper for Telnyx Client

Install

npm install --save @telnyx/react-client @telnyx/webrtc

Usage example

// App.jsx
import { TelnyxRTCProvider } from '@telnyx/react-client';

function App() {
  const credential = {
    login_token: 'mytoken',
  };

  return (
    <TelnyxRTCProvider credential={credential}>
      <Phone />
    </TelnyxRTCProvider>
  );
}

// Phone.jsx
import { useNotification, Audio } from '@telnyx/react-client';

function Phone() {
  const notification = useNotification();
  const activeCall = notification && notification.call;

  return (
    <div>
      {activeCall &&
        activeCall.state === 'ringing' &&
        'You have an incoming call.'}

      <Audio stream={activeCall && activeCall.remoteStream} />
    </div>
  );
}

Hooks

useCallbacks

import { useCallbacks } from '@telnyx/react-client';

function Phone() {
  useCallbacks({
    onReady: () => console.log('client ready'),
    onError: () => console.log('client registration error'),
    onSocketError: () => console.log('client socket error'),
    onSocketClose: () => console.log('client disconnected'),
    onNotification: (x) => console.log('received notification:', x),
  });

  // ...
}

useTelnyxRTC

If you need more fine-tuned control over TelnyxRTC, you also have access to useTelnyxRTC directly.

import { useTelnyxRTC } from '@telnyx/react-client';

function Phone() {
  const client = useTelnyxRTC({ login_token: 'mytoken' });

  client.on('telnyx.ready', () => {
    console.log('client ready');
  });

  // ...
}

Take care to use this hook only once in your application. For most cases, we recommend you use TelnyxRTCContext/TelnyxRTCProvider instead of this hook directly. This ensures that you only have one Telnyx client instance running at a time.

useContext with TelnyxRTCContext

You can retrieve the current TelnyxRTC context value by using React's useContext hook, as an alternative to TelnyxRTCContext.Consumer.

import React, { useContext } from 'react';
import { TelnyxRTCContext } from '@telnyx/react-client';

function Phone() {
  const client = useContext(TelnyxRTCContext);

  client.on('telnyx.ready', () => {
    console.log('client ready');
  });

  // ...
}

Components

TelnyxRTCContextProvider

import { TelnyxRTCProvider } from '@telnyx/react-client';

function App() {
  const credential = {
    // You can either use your On-Demand Credential token
    // or your Telnyx SIP username and password
    // login_token: 'mytoken',
    login: 'myusername',
    password: 'mypassword',
  };

  const options = {
    ringtoneFile: 'https://example.com/sounds/incoming_call.mp3',
    ringbackFile: 'https://example.com/sounds/ringback_tone.mp3',
  };

  return (
    <TelnyxRTCProvider credential={credential} options={options}>
      <Phone />
    </TelnyxRTCProvider>
  );
}

TelnyxRTCContext.Consumer

import { TelnyxRTCContext } from '@telnyx/react-client';

function PhoneWrapper() {
  return (
    <TelnyxRTCContext.Consumer>
      {(context) => <Phone client={context} />}
    </TelnyxRTCContext.Consumer>
  );
}

Audio

import { Audio } from '@telnyx/react-client';

function Phone({ activeCall }) {
  return (
    <div>
      <Audio stream={activeCall.remoteStream} />
    </div>
  );
}

Video

import { Video } from '@telnyx/react-client';

function VideoConference({ activeCall }) {
  return (
    <div>
      <Video stream={activeCall.localStream} muted />
      <Video stream={activeCall.remoteStream} />
    </div>
  );
}
