bluebird-q

Introduction

This is a drop-in replacement for Q version 1.x that delegates to bluebird 3.4.6. Enjoy better stack traces, performance and memory usage without changing your existing legacy code.

Installation:

npm install bluebird-q

Usage:

var Q = require("bluebird-q");

API

Additionaly to Q APIs following methods are availible on Q object:

• Q.getBluebirdPromise(): Returns native bluebird Promise

Testing

Clone this repository and then run npm install && npm test in the cloned directory root.

Caveats

• dispatch, progress and Q.makePromise are unimplemented
• Currently relies on Object.defineProperty so cannot be used in browsers that don't support ES5
• Performance of Q-specific methods is not yet optimized e.g.
  • nfapply
  • nfcall
  • nfbind
  • npost
  • nsend
  • ninvoke
  • nbind
  • nmcall
  • fapply
  • fcall
  • fbind
  • denodeify
  • nmapply
  • mapply
  • post
  • send
  • mcall
  • invoke
  • ....
• However bluebird-specific methods that don't collide with Q names are still available e.g. Q.promisifyAll
• A few original tests had to be modified in spec/q-spec.js, you can find these tests by searching for "Test modified"
