Promise

A lightweight implementation of CommonJS Promises/A for PHP.

Note

This is a fork of reactphp/promise with the following improvements:

• PHP 8.1+ compatibility
• declare(strict_types=1); in all files
• @yield annotations in promise interfaces
• Enhanced type annotations
• Replaces react/promise v2

Install

The recommended way to install this library is through Composer.

composer require internal/promise

Credits

This fork is based on reactphp/promise, which is a port of when.js by Brian Cavalier.

Also, large parts of the documentation have been ported from the when.js [Wiki][Wiki] and the [API docs][API docs].
