Promised version of the node.js fs module. All non-callback-taking functions of fs are simply inherited.

$ npm install then-fs

The API for then-fs is exactly that of the built in fs module except that any function which normally takes a callback returns a promise instead.

Example:

function readJSON(path) {
  return fs.readFile(path, 'utf8').then(JSON.parse)
}
readJSON(__dirname + '/package.json')
  .done(function (obj) {
    console.dir(oj)
  })
