async-fn-callback

I maintain a number of callback oriented libraries(even if they might offer promise interfaces at a high level), due to their much better stack handling properties. While pure promises don't offer much over callbacks, the async/await does offer some complexity benefits (especially if a library already uses promises heavily, meaning you already have a disconnected call stack).

This library gives you the ability to interface with these using the traditional callback idiom(so that you can handle errors and success in the same scope). It's barely any code and only exists so you(I) can avoid boilerplate.

Usage

const Δ = require('async-fn-callback')

Δ(async function(){
    let value = await new Promise((resolve, reject)=>{
        setTimeout(()=>{
            reject(new Error('This is an error!'))
        }, 10);
    })
    return value;
}, (err, result)=>{
    //promises underneath, but idiomatic to callbacks
});

Testing

Just use:

./node_modules/mocha/bin/mocha
