<h2>Getting started with WebRTC <a href="https://github.com/muaz-khan/DataChannel"
target="_blank">DataChannel</a></h2>
<pre>
<script src="https://cdn.webrtc-experiment.com/DataChannel.js"></script>
<script>
var channel = new <strong>DataChannel</strong>('default-channel');
// to send text/data or file
channel.<strong>send</strong>(file || data || 'text');
</script>
</pre>
<br/><br/>
<h2>Features:</h2>
<ol>
<li>Send file directly — of any size</li>
<li>Send text-message of any length</li>
<li>Send data directly</li>
<li>Simplest syntax ever! Same like WebSockets.</li>
<li>Supports fallback to socket.io/websockets/etc.</li>
<li>Auto users' presence detection</li>
<li>Allows you eject any user; or close your entire data session</li>
</ol>
<br/>
<br/>
<h2>Send direct messages!</h2>
<p>In many-to-many data session; you can share direct messages or files between specific users:</p>
<pre>
channel.channels[userid].send(file || data || 'text message');
</pre>
<h2>Detect users' presence</h2>
<p>To be alerted if a user leaves your room:</p>
<pre>
channel.onleave = function(userid) {
// remove that user's photo/image using his user-id
};
</pre>
<br/>
<br/>
<h2>Manually eject a user or close your data session</h2>
<pre>
channel.leave(userid); // throw a user out of your room!
channel.leave(); // close your own entire data session
</pre>
<p>Following things will happen if you are a room owner and you tried to close your data session using <code>channel.leave()</code>:
</p>
<ol>
<li>The entire data session (i.e. all peers, sockets and data ports) will be closed.
<small>(from each and every user's side)</small>
</li>
<li>All participants will be alerted about room owner's (i.e. yours) action. They'll unable to send any single
message over same room because everything is closed!
</li>
</ol>
<h2>Note</h2>: DataChannel.js will never "auto" reinitiate the data session.
<br/>
<br/>
<h2>Additional:</h2>
<pre>
<script>
// to be alerted when data ports get open
channel.<strong>onopen</strong> = function(userid) {
// user.photo.id = userid; ---- see "onleave" and "leave" above ↑
// direct messages!
channel.channels[userid].send(file || data || 'text message');
}
// to be alerted when data ports get new message
channel.<strong>onmessage</strong> = function(message, userid) {
// send direct message to same user using his user-id
channel.channels[userid].send('cool!');
}
// show progress bar!
channel.<strong>onFileProgress</strong> = function (packets) {
// packets.remaining
// packets.sent
// packets.received
// packets.length
};
// on file successfully sent
channel.<strong>onFileSent</strong> = function (file) {
// file.name
// file.size
};
// on file successfully received
channel.<strong>onFileReceived</strong> = function (fileName) {};
</script>
</pre>
<br/>
<br/>
<h2>Errors Handling</h2>
<pre>
<script>
// error to open data ports
channel.<strong>onerror</strong> = function(event) {}
// data ports suddenly dropped
channel.<strong>onclose</strong> = function(event) {}
</script>
</pre>
<br/>
<br/>
<h2>Use your own socket.io for signaling</h2>
<pre>
<script>
// by default socket.io is used for signaling; you can override it
var channel = new <strong>DataChannel</strong>('default-channel', {
openSignalingChannel: function(config) {
var socket = io.connect('http://your-site:8888');
socket.channel = config.channel || this.channel || 'default-channel';
socket.on('message', config.onmessage);
socket.send = function (data) {
socket.emit('message', data);
};
if (config.onopen) setTimeout(config.onopen, 1);
return socket;
}
});
