Simple command queue which doesn't require any external service.

Command Queue

Command queues have not much on their shoulders so far: they just trigger the "commandPushed" & "commandRemoved" events when commands are pushed into or removed from them.

Note: Command pattern implementation is based on command-pattern.

Example

var queue = new CommandQueue();

queue.when("commandPushed", function(command) {
	// Well... do something, please! For example:
	command.execute(function(error, results) {
		queue.remove(command);
	});
});

queue.when("commandRemoved", function() {
	// There you could do something as well.
});
