cls-domains-promise

Certain asynchronous operations in continuation-local-storage and node.js domain breaks with few promise libraries. It utilizes then function in promise libraries and makes it safe to work with them by binding callbacks passed to active context (cls or domains)

How to use it ?

Eg: 1: To patch mongoose internal promise library (mpromise) for cls

var patchIt = require('cls-domains-promise');
var cls = require('continuation-local-storage'); 
var mongoose = require('mongoose');
var proto = mongoose.Mongoose.prototype.Promise.prototype;
// or cls.getNamespace if exists
var appSpace = cls.createNamespace('app');
patchIt(appSpace, proto);

Eg: 2: To patch promise.js for node.js domains

var patchIt = require('cls-domains-promise');
var promise = require('promise');
var proto = promise.prototype;
var appSpace = process.domain;
patchIt(appSpace, proto);

Voila! now use it as usual.
