Text Editing Example

Here, I will give a short overview on how to enable collaborative text editing with the PeerJs Connector and the TextYatta Framework. First you have to include the following libraries in your html file:

<script src="http://cdn.peerjs.com/0.3/peer.js"></script>
<script src="../../build/browser/Frameworks/TextYatta.js"></script>
<script src="../../build/browser/Connectors/PeerJsConnector.js"></script>
<script src="./index.js"></script>

Open index.html in order to start collaboration.

var yatta;

function init(){
    Y.createPeerJsConnector({key: 'h7nlefbgavh1tt9'}, function(Connector, user_id){

TextYatta is a shared text object. If you change something on this object, it will be instantaneously shared with all the other collaborators.

      yatta = new Y.TextYatta(user_id, Connector);

Get the url of this frame. If it has a url-encoded parameter we will connect to the foreign peer.

      var url = window.location.href;
      var peer_id = location.search
      var url = url.substring(0,-peer_id.length);
      peer_id = peer_id.substring(1);

Set the shareable link.

      document.getElementById("peer_link").setAttribute("href",url+"?"+user_id);

Connect to other peer.

      if (peer_id.length > 0){
        yatta.connector.connectToPeer(peer_id);
      }

Bind yatta to the textfield.

The .bind property is a method of the Word class. You can also use it with all the other Frameworks in Yatta (e.g. Json).

      var textbox = document.getElementById("textfield");
      yatta.bind(textbox);
    });
}
window.onload = init
