The project's purpose is to provide PHP developers with a set of complete tools to build functional async applications. Please, make sure you read the attached README carefully and it is guaranteed you will be surprised how easy to use and powerful it is. In the meantime, you might want to check out the rest of our async libraries in [Dazzle repository](https://github.com/dazzle-php) for the full extent of Dazzle experience.

Feature Highlights ------------------ [](#feature-highlights) Dazzle Promise features: - Implementation of promises, - Methods to resolve, reject or cancel promises, - Cancellation of promises using forget semantics, - Methods to join, map, race, reduce and do other things with set of promises, - ...and more. Provided Example(s) ------------------- [](#provided-examples) ### Quickstart [](#quickstart) TODO ### Additional [](#additional) TODO Requirements ------------ [](#requirements) Dazzle Promise requires: - PHP-5.6 or PHP-7.0+, - UNIX or Windows OS. Installation ------------ [](#installation) To install this library make sure you have [composer](https://getcomposer.org/) installed, then run following command: ``` $> composer require dazzle-php/promise ``` Tests ----- [](#tests) Tests can be run via: ``` $> vendor/bin/phpunit -d memory_limit=1024M ``` Versioning ---------- [](#versioning) Versioning of Dazzle libraries is being shared between all packages included in [Dazzle Project](https://github.com/dazzle-php/dazzle). That means the releases are being made concurrently for all of them. On one hand this might lead to "empty" releases for some packages at times, but don't worry. In the end it is far much easier for contributors to maintain and -- what's the most important -- much more straight-forward for users to understand the compatibility and inter-operability of the packages.
