Earlier today I was greeted by a Pull Request on my first post from GitHub user @j-f1.

PR on my last post, showing how to use Promise.allSettled() now!

It turns out there is a handy way to add Promise.allSettled() to your apps right now! πŸŽ‰. Β It's fiendishly simple to use, too.

The core-js npm package

That's right - core-js. Β From their README.md, it is exactly what it sounds like:

Looking further down in the readme, there's a list of supported features in the polyfill:

Well hot damn! That'll do it!

How to use core-js

As @j-f1 indicated, in any project that uses babel as a transpiler, all you need to do is add core-js to your project, and include it at your app's entry point:

First, add the dependency to your project

1
> yarn add core-js

Then, at your app's entry point (usually something like index.js, or app.js in the root of your project):

1
import 'core-js';

or, if you want to include just the Promise.allSettled() polyfill, and nothing else, use:

1
import 'core-js/proposals/promise-all-settled';

That's it! 🍻
