AsyncOrder for NodeJS
AsyncOrder is simple solution for making "callback hell" more readable and just for making simple callback chains
##Installation Use NPM to install this module:
$ npm install async-order
##Dependencies
Well, none. It's pure JS solution
##Example
var http = require('http');
var AsyncOrder = require('async-order');
var p = new AsyncOrder(); //Creating new chain
//Every step add link on given function in our chain.
p.step(function(next) { //Given function recieves callback as argument, that needs to be executed to continue chain execution
http.get('http://google.com/', next); //Calling async function, used 'next' as our callback
}).step(function(next, res) { //Next step recieves not only callback, but also arguments recieved by previous 'next' callback
console.log('Headers: ' + res.headers);
next('Sample text :b'); //Of course you may just call it by yourself and give it needed arguments
}).step(function(next, msg) {
console.log('We got your message, friend: ' + msg);
throw new Error('You used too much characters in your message');
}).catch(function(err) {
console.log('General, we a problem: ' + err.message);
}).done();
