instapromise

Promisify node style async functions by putting a .promise after them (or after the object for methods)

If you use this library then if you put .promise after a Node-style async function, it will turn it into a function that returns a Promise instead of taking a callback.

The original function is available as a property on the Promise generating function (.___instapromiseOriginalFunction___).

  promisify = require 'instapromise'
  p = fs.readFile.promise "/tmp/hello", 'utf8'
  p.then(console.log)

If you want to promisify methods, use .promise after the object and before the method name.

  promisify = require 'instapromise'
  p = fs.promise.readFile "/tmp/hello", 'utf8'
  p.then(console.log)
