promise-native-deferred v3.0.0

promise-native-deferred

This is a fork of promise-deferred, but instead uses the environment's native Promise implementation instead of a polyfill. This means that browser tools won't unnecessarily bundle a Promise polyfill when one already exists or Promise is provided natively.

Usage

var deferred = new Deferred()

In order to use this module in environments without Promises, either polyfill ahead-of-time or pass your custom Promise during Deferred construction like so:

var deferred = new Deferred(MyPromise)

or simply:

var deferred = Deferred(MyPromise)

A lightweight Deferred implementation, on top of Promises/A+

Examples

var Deferred = require('promise-deferred');

var deferred = new Deferred();

// set up handlers
deferred.promise.then(function (value) {}, function (error) {});

// resolve
deferred.resolve('a value');

// reject
deferred.reject(new Error('oh noes'));

Tests

Simply clone the repo, npm install, and run npm test
