npm install @permettezmoideconstruire/cancellable-promiseinclude
<script src="https://unpkg.com/@permettezmoideconstruire/cancellable-promise"></script>You can specify a npm release with @
<script src="https://unpkg.com/@permettezmoideconstruire/[email protected]"></script>Promise object.
It's compatible with node.js implementation, and most browsers one.
You should polyfill Promise for older browsers though.
