Event Loop
==========

[](#event-loop)

This library's core uses the [reactor pattern](https://en.wikipedia.org/wiki/Reactor_pattern) to handle normally [blocking I/O](https://nodejs.org/en/docs/guides/blocking-vs-non-blocking/#blocking) function/event **calls**.

Concepts
--------

[The Reactor and Singleton Pattern](https://youtu.be/pmtrUcPs4GQ) **video**

[Patterns and Frameworks for Synch Event Handling, Connections, and Service Initialization](https://youtu.be/m-J9FCFOMUE) **video**

The [*reactor pattern*](https://youtu.be/izdvImum8ow) is an event handling pattern for handling service requests delivered concurrently to a service handler by one or more inputs. @see [Reactor](https://github.com/tpn/pdfs/blob/master/Reactor%20-%20An%20Object%20Behavioral%20Pattern%20for%20Demultiplexing%20and%20Dispatching%20Handles%20for%20Synchronous%20Events.pdf) - An Object Behavioral Pattern for Demultiplexing and Dispatching Handles for Synchronous Events.

PHP wasn't built from the ground up with an [Event Loop](https://en.wikipedia.org/wiki/Event_loop) concept in mind, like other Languages, *Python*, *JavaScript* for one.

Like *Python* and *JavaScript*, *PHP* is single threaded. It can handle asynchronous event base programming quite well, however there is no standard library way to implement.

[What Is Async, How Does It Work, and When Should I Use It?](https://youtu.be/kdzL3r-yJZY) **video**

[Common asynchronous patterns](https://youtu.be/jq2IFUQRbGo) **video**

In order to have any async behavior programming, the based libraries needs to be interoperable, and they need to use the same event loop.

This Event Loop form the the basics for our **[Promise/A+](https://github.com/uppes/promisplus)** package.

This component provides a common `LoopInterface` that any library can target. This allows them to be used in the same loop, with one single [`run()`](#run) call that is controlled by the user.
