cbfy

Installation

npm install cbfy

Usage

Call a callback after a Promise return

const cbfy = require('cbfy')

Promise.resolve().then(...cbfy(cb))

Why ?

Promises are sometimes counter intuitive, specially when mixin Promises and callbacks. Of course you want avoid that situation, but when migrating from legacy code, it's good to have a way.

This package is a little bit similar to [nodify](https://www.npmjs.com/package/nodeify), or at least try to solve the same problem. it just does it with a diffent interface, using object spreading, in order to respect the then(successCb, errorCb) syntax

Warning

You have to be carefull about thwn you want use it, or not. Once you call cbfy, everything that happend in your cb will be runned asyncronously and escaped of the Parent promise. You probably don't want chain anything after the then(...cbfy(cb)) call.

For example, if even if you callback return a Promise you can`t chain it the same way as you would without cbfy. This is by design.
