light-promise

A Super Lightweight Promise/A+ and ES6-promise implementation, tested by promises-tests and promises-es6-tests

This project mainly focus on Promise/A+, with some tricks to fulfill ES6-promise standard.

Usage

Node

Run npm install -S light-promise in command line. Then,

let Promise = require('light-promise')

Browser

Download the light-promise.min.js file.

Light-promise is also a bower package.

• Add a script tag in your HTML file

<script src="/light-promise.js"></script>

• The global variables Promise is available after the above script tag.
  • Notice that if the browser supports Promise natively, Promise variable will keep to be the native one, which I recommend you to use.

var p = new Promise(function(resolve, reject){
    // ...
})
p.then(function(){})

You can also use light-promise with requirejs or browserify as well.
