Summary

JavaScript framework designed primarily for asynchronous push communication with custom servers (comet). Python back-end examples included, as well as a basic JavaScript effects library, and ActionScript source for handling the active connections.

The Push Communication framework uses Flash's XMLSocket object as a middle layer. Sample back-end servers included are written in Twisted. Twisted is an event-driven networking engine written in Python

Real Usage Example

Photos.cx's Photos Spy (now offline)

Used photos.py and photos_sender.py along with the Effects and Push framework to notify users of new public uploads. Featured real-time chat room used to discuss new uploads with other users. Custom front-end code

Examples

Using the Push Communication Framework

<embed width="0" height="0" allowscriptaccess="always" name="flashSock" id="flashSock" 
src="./swf/jsCom.swf" type="application/x-shockwave-flash"></embed>

<script type="text/javascript">
	var onData = function(data) {
	    alert('Server said:' + data);
	}
	var onClose = function() {
	    alert('Goodbye.');
	}

	// initialize connection with server running on localhost port 3002 (included)
	var fs = new AONIC.api.PushCommunication('localhost', '3002', 'flashSock');

	fs.addCallback('onData', onData).addCallback('onClose', onClose);

	fs.send('John Doe.'); // -> alert('Server said: Welcome John Doe!');
</script>

Using the Effects Framework

<div id="photoBox" style="height:0; overflow:hidden;">
	<img src="../photo.jpg" />
</div>

<script type="text/javascript">
	new AONIC.api.Effects('photoBox', 0, 300, 'height', {duration:300}).slide();
</script>

Quick and Dirty Chat Room using chatd.py and Push Framework

Start the server: python chatd.py

Webpage

<embed width="0" height="0" allowscriptaccess="always" name="flashSock" id="flashSock"

<script type="text/javascript" src="./js/AONIC.Com.js"></script>

<script type="text/javascript">
	var fs;
	window.onload = function() {
	    // safari 3.0 needs a little more time
	    setTimeout((function() {
	        fs = new AONIC.api.PushCommunication('localhost', '3002', 'flashSock');
	    
	        fs.addLine = function(line) {
	            if(line.length == 0) return;
	            AONIC.$('chat').value += '\n'+line;
	            AONIC.$('chat').scrollTop = AONIC.$('chat').scrollHeight;
	        };
	        fs.sendMessage = function(input) {
	            var msg = input.value;
	            if(msg.length == 0) return;
	            input.value = '';
	    
	            this.send(msg);

	            }
	            this.addLine(this.username + '> ' + msg);
	        };
	    
	        fs.addCallback('onData', fs.addLine);
	    }), 100);
	};
