promissory v1.0.2

Promissory

Turn a regular node function into one which returns an ES6 Promise. This can also be used with generator-based flow control such as co.

This project is a direct port of tj/thunkify. Instead of creating thunks, it creates promises.

This is tested with Node v0.10 up to v5. A Promise polyfill is required to be set globally on v0.10.

Installation

$ npm install promissory

Example

var promisify = require('promissory').promisify;
var fs = require('fs');

var readPromissory = promisify(fs.readFile);

readPromissory('package.json', 'utf8').then(function(str) {
	console.log('str');
}, function(err) {
	console.error(err);
});
