yui-promise

Promises allow you to interact with a value that may or may not be available yet.

Getting Started

YUI promises can be loaded as:

• A script that acts as a polyfill for native promises and adds a global Promise constructor if the native version is not available
• A Node.js module available in npm
• An AMD module
• As part of the YUI library. See its User Guide
• Using Bower as yui-promise

Node.js

Installation

To use YUI promises in Node.js, add the yui-promise module to your dependencies in the package.json file of your project:

{
	"dependencies": {
		"yui-promise": "0.0.3"
	}
}

Install it using npm:

$ npm install

Usage

The yui-promise module exports the Promise constructor:

var Promise = require('yui-promise');

function asyncFunction() {
	return new Promise(function (resolve, reject) {
		resolve('Hello world');
	});
}
