SendBird JavaScript Widget Sample

This is a sample chat widget built using using the SendBird SDK. It can be used to add a functional chat widget to any website.


You can try out a live demo from the link here. Click on the button at the bottom-right corner of the webpage to try out the widget. Choose any 'User ID' and 'Nickname' to log in and participate in chats.


  1. The body must have a div element whose id is sb_widget.
  <div id="sb_widget"></div>
  1. Import the SendBird SDK.
  2. Import the widget.SendBird.js file.
<script src="SendBird.min.js"></script>
<script src="build/widget.SendBird.js"></script>

Customizing the widget

If you refresh your browser window, you need to reconnect to SendBird. To retain connection on browser refresh, you must implement an appropriate event handler.

If you wish to issue an access_token for your user, modify the connect function in src/sendbird.js.

Require that you have Node installed.

  1. Install npm

     npm install
  2. Modify files.

     npm run start-dev
  3. Start sample.

     npm start


Connect other APP or Channel

If you want to connect other application, you need to change variable appId in index.html.


  <script src="SendBird.min.js"></script>
  <script src="build/widget.SendBird.js"></script>
    var appId = '<APP_ID>';


Start with User connect

If you want to start this sample with user connect, you can using startWithConnect().


  <script src="SendBird.min.js"></script>
  <script src="build/widget.SendBird.js"></script>
    var appId = '<APP_ID>';
    var userId = '<USER_ID>';
    var nickname = '<NICKNAME>';
    sbWidget.startWithConnect(appId, userId, nickname, function() {
      // do something...


Show Channel

If you want to open chat, you can using showChannel().

var channelUrl = '<CHANNEL_URL>';
