call-next-tick v2.0.1

call-next-tick

(Formerly 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 call-next-tick

Usage

var callNextTick = require('call-next-tick');

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

Instead of:

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

So, here's the implementation:

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

	function callNextTick(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. :)
