lafy

lafy is a ridiculously small module that adds a simpler way to promisify instance methods. It can obviously be used on normal promisifiable methods:

const fs = require('fs');
const lafy = require('lafy');

// Don't want to bother promisifying a function ?
let contents = await lafy(cb => fs.readFile("/etc/passwd", cb));

// Oh no, this class' methods use callbacks ;(
// The only way to promisify methods would be to bind them to an instance
const userManager = new UserManager(/* ... */);
let users = await lafy(cb => userManager.getUsers(cb));
// Much simpler if you only need to do this once or twice !
