    Installation

    NPM

    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();
    }

    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="//sdk.twilio.com/js/video/releases/2.18.1/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());
    }

    Content Security Policy (CSP)

    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
    

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

    Building

    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.

    Testing

    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>
    

    Tips

    • 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
