WebRTC (Web Real-Time Communications) is a technology which enables Web applications and sites to capture and optionally stream audio and/or video media, and to exchange arbitrary data between browsers without requiring an intermediary. The set of standards that comprises WebRTC makes it possible to share data and perform teleconferencing peer-to-peer, without requiring that the user install plug-ins or any other third-party software.

Clone the project repository by running the command below if you use SSH

git clone [email protected]:samuelayo/pusher_webrtc.git

If you use https, use this instead

git clone https://github.com/samuelayo/pusher_webrtc.git

Change directory into the newly cloned project and install dependencies

cd pusher_webrtc
npm install

If you don't have one already, create a free Pusher account at https://pusher.com/signup then login to your dashboard and create an app.

Then fill in your Pusher app credentials in your index.js file by replacing this line with your appid, appkey and app secret respectively:

const pusher = new Pusher({
    appId: 'XXX-APP-ID',
    key: 'XXX-APP-KEY',
    secret: 'XXX-APP-SECRET',
    cluster: 'XXX-APP-CLUSTER',
    encrypted: true
});

Also, remember to fill in the your app key and app cluster in your index.html file by updating this line:

var pusher = new Pusher('XXX-APP-KEY', {
    cluster: 'XXX-APP-CLUSTER',
    encrypted: true,
    authEndpoint: 'pusher/auth'
});

And finally, start the application by running:

node index.js
