Pall

Your best pall with promises. Module helps you control the Promise.all function by passing object with Promises. This is alpha version written in ES6 with Lodash library as a helper and it is design to be used in Node 4+.

How to install

Just install package with npm:

npm install pall

...and require it in your project:

const Pall = require('pall');

How to use it

The only argument of the function is object of Promises.

First you need to prepare your promises, ex.:

function promiseOne() = {
    return new Promise((resolve, reject) => {
        resolve(...);
        reject(...);
    });
}

function promiseTwo() = {
    return new Promise((resolve, reject) => {
        resolve(...);
        reject(...);
    });
}

Then put these promises into the object:

const objectWithPromises = {
    p1: promiseOne(),
    p2: promiseTwo()
}

After that just put the object as an argument into Pall function:

Pall(objectWithPromises)

Since Pall under the hood executes simple Promise.all, you can just "then" and "catch" the function:

Pall(objectWithPromises)
    .then(resolve => {...})
    .catch(reject => {...});

Resolve returns the very same object which you've passed as an argument, but with resolved promises.
