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

varpromisify=require('promissory').promisify;varfs=require('fs');varreadPromissory=promisify(fs.readFile);readPromissory('package.json','utf8').then(function(str){console.log('str');},function(err){console.error(err);});
