const Video = require('twilio-video');

CDN

Releases of twilio-video.js are hosted on a CDN, and you can include these directly in your web app using a <script> tag.

<script src="//media.twiliocdn.com/sdk/js/video/releases/2.0.0-beta2/twilio-video.min.js"></script>

Using this method, twilio-video.js will set a browser global:

const Video = Twilio.Video;

Usage

The following is a simple example for connecting to a Room. For more information, refer to the API Docs.

const Video = require('twilio-video');

Video.connect('$TOKEN', { name: 'room-name' }).then(room => {
  console.log('Connected to Room "%s"', room.name);

  room.participants.forEach(participantConnected);
  room.on('participantConnected', participantConnected);

  room.on('participantDisconnected', participantDisconnected);
  room.once('disconnected', error => room.participants.forEach(participantDisconnected));
});

function participantConnected(participant) {
  console.log('Participant "%s" connected', participant.identity);

  const div = document.createElement('div');
  div.id = participant.sid;
  div.innerText = participant.identity;

  participant.on('trackSubscribed', track => trackSubscribed(div, track));
  participant.on('trackUnsubscribed', trackUnsubscribed);

  participant.tracks.forEach(publication => {
    if (publication.isSubscribed) {
      trackSubscribed(div, publication.track);
    }
  });

  document.body.appendChild(div);
}

function participantDisconnected(participant) {
  console.log('Participant "%s" disconnected', participant.identity);
  document.getElementById(participant.sid).remove();
}

function trackSubscribed(div, track) {
  div.appendChild(track.attach());
}

function trackUnsubscribed(track) {
  track.detach().forEach(element => element.remove());
}
