conform-async

A handy wrapper for process.nextTick that you can use to call a callback on the next tick instead of immediate, even though you have the results for callback. Here's why you'd want to do this (scroll to "It is very important...").

Installation

npm install conform-async

Usage

var conformAsync = require('conform-async');

// callback expects to be called async.
function getResultForSpecialSituation(id, callback) {
	var error = null;
	var constantResult = 'This is always the result';
		conformAsync.callBackOnNextTick(callback, error, constantResult);
	}

So, here's the implementation:

	function makeCallbackCaller(cb, error, result) {
		return function callbackCall() {
			cb(error, result);
		};
	}

	function callBackOnNextTick(cb, error, result) {
		process.nextTick(makeCallbackCaller(cb, error, result));
	}

It's not much. It's just something I don't want to copy from project to project. :) (makeCallbackCaller is exposed in case you want to use make a callback wrapper and pass it to setTimeout or something instead of process.nextTick.)
