NodeJS Asterisk Manager API

For a project of mine I needed a low level interface to the Asterisk Manager API. I looked around and found https://github.com/mscdex/node-asterisk . While it was a good starting point, it had too many abstractions for my taste. Which is why I based my version on it an then radically refactored it. In the end there now is very little in common with it.

So this is basically a different piece of work, but since there is a shared DNA and I got a good start by depending on Brian's work, I feel like giving credit is appropriate.

API Overview

var manager = new (require('asterisk'))(5038, 'localhost');

manager.on('connect', function(err, val) {
	manager.authenticate('username', 'password');
});

manager.on('close', function() {});
manager.on('error', function(err) {});
manager.on('managerevent', function(evt) {});
manager.on('response', function(res) { /* This is done because we can, not because it is needed! */});
manager.connect();
/*
Possible parameters to connect() are username, password, and a boolean indicating whether the connection should be reconnected if it fails.
All parameters are optional and are only used for reconnection not for the first authentication!
*/

manager.action({
	'action':'originate',
	'channel':'SIP/myphone',
	'context':'default',
	'extension':1234,
	'priority':1,
	'variables':{
		'name1':'value1',
		'name2':'value2'
	}
}, function(err, res) {});
/*
	Variables are automatically put in the right format. Aside from that everything is passed straight through to Asterisk. See Manager API documentation for what is possible.
*/

manager.disconnect();
