Type Definitions





Temasys Web SDK (formerly SkylinkJS) is an open-source client-side library for your web-browser that enables any website to easily leverage the capabilities of WebRTC and its direct data streaming powers between peers for audio/video conferencing or file transfer.

We've gone to great length to make this library work in as many browsers as possible. Temasys Web SDK is built on top of AdapterJS and works with our Temasys WebRTC Plugin even in Internet Explorer and Safari on Mac and PC.

You'll need a Temasys Account and an App key to use this. Register here to get your App key.

Supported Browsers

Browsers in Beta (Edge/Bowser/Safari):

Note that for beta supported browsers, some of the audio / video functionalities may not work well. Some older versions of Edge may require you to enable experimental support for H.264 video codec to interop with Chrome and Firefox browsers.

Current versions and stability

We recommend that you always use the latest versions of the Temasys Web SDK as WebRTC is still evolving and we adapt to changes very frequently.

Latest version: 0.6.26.

Setting AdapterJS flags

If you require to set Temasys AdapterJS flags (e.g. forcing Temasys WebRTC plugin), we recommend the following method:

  // Example options.
  var AdapterJS = {
    options: {
      forceSafariPlugin: [Boolean],
      hidePluginInstallPrompt: [Boolean],
      getAllCams: [Boolean]
<! -- Now reference AdapterJS or SkylinkJS (complete version) -->

For more details, please read the documentation in Temasys AdapterJS.

Noted Issues and Solutions

Installing 0.6.3 - 0.6.10 versions in NPM

Due to corrupt files issues for versions 0.6.3 - 0.6.10, we have removed these versions from the NPM repository. You may still install these versions using this command:

npm install git://github.com/Temasys/SkylinkJS#<version_tag>
Encoding issues from AdapterJS dependency

There is a known issue caused by AdapterJS 0.14.0 which manifests as incorrectly encoded characters. To resolve this, it is recommended that charset is set the HTML file:

<meta charset="utf-8">
Upgrading from 0.5.7 and below:

It's now recommended to use the init() callback instead of using readyStateChange complete state as this may result in an infinite loop.

readyStateChange triggers each time the current room information is recieved, and joining a room other than default room will result in a re-fetch from the API server. This can result in a endless re-join loop.

// Use this
sw.init(data, function () {

// Instead of
sw.on('readyStateChange', function (state) {
  if (state === sw.READY_STATE_CHANGE.COMPLETED) {
