** twilio-video.js supports the Chromium-based Edge browser.

npm install twilio-video --save

Using this method, you can require twilio-video.js like so:

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

TypeScript definitions can now be imported using this method.

import * as Video from 'twilio-video';

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

Alternatively, you can import just the definitions you need like so:

import { RemoteParticiant } from 'twilio-video';

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

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="//sdk.twilio.com/js/video/releases/2.28.1/twilio-video.min.js"></script>

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

const Video = Twilio.Video;

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());
}

Want to enable CSP in a way that's compatible with twilio-video.js? Use the following policy directives:

connect-src wss://global.vss.twilio.com wss://sdkgw.us1.twilio.com
media-src mediastream:

If you're loading twilio-video.js from sdk.twilio.com, you should also include the following script-src directive:

script-src https://sdk.twilio.com

If you are enabling Krisp Noise Cancellation for your local audio, and you are using the following default-src self directive, you should also add the unsafe-eval directive:

default-src self unsafe-eval

Keep in mind, you may need to merge these policy directives with your own if you're using other services.

Fork and clone the repository. Then, install dependencies with

npm install

Then run the build script:

npm run build

The builds and docs will be placed in the dist/ directory.

Run unit tests with

npm run test:unit

Run integration tests with

ACCOUNT_SID=<Your account sid> \
API_KEY_SID=<Your api key sid> \
API_KEY_SECRET=<Your api key secret> \
BROWSER=<Browser you'd like to use> \
npm run test:integration

You can add these optional variables to control the integration test execution :

• Topology : Decides which type of rooms to test against.
• Debug : To get better source mapping, and the browser does not close after tests are run which allows you to easily step through code to debug.
• Test Files : Allows you to limit the test to just one file.

TOPOLOGY=<peer-to-peer|group>
DEBUG=1
TEST_FILES=<path_ to_the_file>

• Use Pre-commit hook: We have some useful pre-commit hook that would help identify common mistakes before commit. Use them by executing

ln -s ../../pre-commit.sh .git/hooks/pre-commit
