Twilio Sync JavaScript client library

Twilio Sync is Twilio's state synchronization service, offering two-way real-time communication between browsers, mobiles, and the cloud. Visit our official site for more details: https://www.twilio.com/sync

Installation

NPM

npm install --save twilio-sync

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

var SyncClient = require('twilio-sync');
var syncClient = new SyncClient(token);

CDN

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

<script type="text/javascript" src="//media.twiliocdn.com/sdk/js/sync/v0.12/twilio-sync.min.js"></script>

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

var syncClient = new Twilio.Sync.Client(token);

Usage

To use the library, you need to generate an Access Token and pass it to the Sync Client constructor. The Twilio SDK Starter applications for Node.js, Java, PHP, Ruby, Python, C# provide an easy way to set up a token generator locally. Alternatively, you can set up a Twilio Function based on the Sync Access Token template. 

// Obtain a JWT access token: https://www.twilio.com/docs/sync/identity-and-access-tokens
var token = '<your-access-token-here>';
var syncClient = new Twilio.Sync.Client(token);

// Open a Document by unique name and update its value
syncClient.document('MyDocument')
  .then(function(document) {
    // Listen to updates on the Document
    document.on('updated', function(event) {
      console.log('Received Document update event. New value:', event.value);
    });

    // Update the Document value
    var newValue = { temperature: 23 };
    return document.set(newValue);
  })
  .then(function(updateResult) {
    console.log('The Document was successfully updated', updateResult)
  })
  .catch(function(error) {
    console.error('Unexpected error', error)
  });
