## PeerJs + JSON Example
Here, I will give a short overview on how to enable collaborative json with the
[PeerJs](http://peerjs.com/) Connector and the Json Framework. Open
[index.html](http://dadamonad.github.io/Yatta/examples/PeerJs-Json/index.html) in your Browser and
use the console to explore Yatta!
[PeerJs](http://peerjs.com) is a Framework that enables you to connect to other peers. You just need the
user-id of the peer (browser/client). And then you can connect to it.
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/JsonFramework.js"></script>
<script src="../../build/browser/Connectors/PeerJsConnector.js"></script>
<script src="./index.js"></script>
```
### Create Connector
The PeerJs Framework requires an API key, or you need to set up your own PeerJs server.
Get an API key from the [Website](http://peerjs.com/peerserver).
The first parameter of `createPeerJsConnector` is forwarded as the options object in PeerJs.
Therefore, you may also specify the server/port here, if you have set up your own server.
*/
var yatta, yattaHandler;
/**
This will connect to the server owned by the peerjs team.
For now, you can use my API key.
*/
connector = new XMPPConnector();
/**
### Yatta
yatta is the shared json object. If you change something on this object,
it will be instantly shared with all the other collaborators.
*/
yatta = new Yatta(connector);
window.onload = function(){
var textbox = document.getElementById("textfield");
yatta.observe(function(events){
for(var i=0; i<events.length; i++){
var event = events[i];
if(event.name === "textfield" && event.type !== "delete"){
yatta.val("textfield").bind(textbox);
}
}
});
yatta.val("textfield","", "mutable");
};
