pmod

Get your node modules with functions that return promises if you don't give them a callback.

If you request a module that is not supported, it will give you the default module instead.

These modules are currently supported: child_process, cluster, crypto, dgram, dns, fs, http, http2, https, inspector, net, realine, stream, timers, tls, zlib

PS: Currently not all functions are tested. But should work in theory. :-D

Install

npm install pmod --save

Use

const fs = require('pmod').fs;

fs.readFile('myfile', 'utf8').then(data => {
	// do stuff with data
	console.log(data);
}).catch(err => {
	// do stuff with err
	console.log(err);
});

The functions work as normal as well!

const fs = require('pmod').fs;

fs.readFile('myfile', 'utf8', (err, data) => {
	if (err) {
		// do stuff with err
		console.log(err);
	} else {
		// do stuff with data
		console.log(data);
	}
});

Module classes

Classes inside of modules have their prototype functions also modified.

This means that you can use promises in their async versions.

const fs = require('pmod').fs;

let stream = fs.createWriteStream('myfile'); // returns a fs.WriteStream object

stream.write('test')
	.then(() => stream.write('next'))
	.then(() => stream.write('last'))
	.then(() => stream.end())
	.catch(err => console.log(err));

Known issues

There may be some class methods that have been forgotten, simply due to the fact that inherited class methods aren't usually listed in the node documentation.

Please create an issue and/or a pull request on github if that is the case.
