Px

Extension functions for JS Promise

Platform	Build Status
Linux
Windows

Introduction

Px allows the extension of the native Promise objects by adding additional functions to its prototype. Px also introduces two Promise variants:

DeferredPromise which is a Promise that, unlike a vanilla Promise, does not call the executor passed to its constructor synchronously but calls it whenever a callback is attached to it (so it produces a different Promise objects every call).
PublishedPromise, which allows asynchronous fulfillment.

Install

NPM

npm i promise-ex

then in NodeJs:

let Px = require('promise-ex');
