This is a follow-up to my first post on the upcoming
Promise.allSettled() function, coming soon to a node application near you.
Earlier today I was greeted by a Pull Request on my first post from GitHub user
It turns out there is a handy way to add
Promise.allSettled() to your apps right now! 🎉. It's fiendishly simple to use, too.
That's right - core-js. From their
README.md, it is exactly what it sounds like:
- The latest ECMAScript standard.
- ECMAScript standard library proposals.
- Some WHATWG / W3C standards (cross-platform or closely related ECMAScript).
- It is maximally modular: you can easily choose to load only the features you will be using.
- It can be used without polluting the global namespace.
- It is tightly integrated with
babel: this allows many optimizations of
Looking further down in the readme, there's a list of supported features in the polyfill:
Promise.allSettledstage 2 proposal
Well hot damn! That'll do it!
@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
> yarn add core-js
Then, at your app's entry point (usually something like
app.js in the root of your project):
or, if you want to include just the
Promise.allSettled() polyfill, and nothing else, use:
That's it! 🍻
