Promisified Node.js core modules
This module behaves as a wrapper module around Node.js' builtin modules and provides a Promise-based APIs for all the callback-based functions. So, instead of fs.readFile('/img.jpg', (err, contents) => {}) you can do const contents = await fs.readFile('/img.jpg').
Currently this module returns Bluebird instances.
There are several other methods which allow you to do Promise-based programming.
new Promise(): Too verbose just to wrap a callback-based function into a PromiseBluebird.fromCallback(): Works great, but creates unnecessary boilerplate code every time you want to call a callback-based functionBluebird.promisify()&Bluebird.promisifyAll(): Much better, but requires an explicit promisification step. Also the new functions have a different name (*Async())
This module takes a different approach - it provides a fully-functional, no build step required, module which you can install and simply start using. Just prefix your require or import calls with promisified-core/ (ie. import fs from 'promisified-core/fs' or import { fs } from 'promisified-core') and you are done!
All builtin modules are available for importing through this module. You just need to import it from this package:
// ES2015 way
import * as core from 'promisified-core'
import { fs, os, http } from 'promisified-core'// CommonJS way
const core = require('promisified-core')
const fs = require('promisified-core/fs')
const fs = require('promisified-core').fsLooking for suggestions, improvements, bug reports... any kind of contribution is welcome!
