finally-polyfill

A tiny ~150-byte polyfill for Promise.prototype.finally.

Useful for browsers that support Promise but not the .finally() method.

Usage

npm install finally-polyfill

It's a polyfill, so you can import, require() or drop it in a script tag - all the same.

import 'finally-polyfill';
Promise.reject('oops').finally(() => { /* ... */ })

<script src="/path/to/finally-polyfill.min.js"></script>
