🚫 (This project is no longer maintained.)

This bundle integrates react/event-loop library into the Symfony 2.

Master branch status:

Installation

Use a Composer to install LitGroupEventLoopBundle.

"require": {
    "litgroup/event-loop-bundle": "1.0.x-dev"
}

Do not forget to register the bundle in the AppKernel:

<?php // AppKernel.php

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = [
            // ...
            new LitGroup\Bundle\EventLoopBundle\LitGroupEventLoopBundle(),
        ];
        // ...

        return $bundles;
    }
 	
    // ...   
}

Configuration

No configuration needed this time.

Basic usage

Using of an event loop

Bundle provides basics loop as a service, named litgroup_event_loop. You can use it for injection or directly in your application.

Example:

/** @var \React\EventLoop\LoopInterface $loop */
$loop = $container->get('litgroup_event_loop');

$loop->run();

Periodic Services

Periodic service — service, defined in the dependency injection container, marked by tag litgroup_event_loop.periodic. These services will be called periodically when loop is running.

Tag has two required attributes:

interval — interval between calls;
method — service method to call.

Interval can be set as seconds represented by double value or as string with time units (10ms, 1m). Interval cannot be less then 1ms.

String representation supports four units:

ms milliseconds
s seconds
m minutes
h hours

Units cannot be mixed.

Example: 10s, 15m, 1.5h

Periodic service definition's example

Service class:

<?php

class PeriodicService
{
	public function tick()
	{
		echo "Tick!";
    }
}

DIC configuration:

<?xml version="1.0" encoding="UTF-8" ?>
<container xmlns="http://symfony.com/schema/dic/services"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://symfony.com/schema/dic/services
        http://symfony.com/schema/dic/services/services-1.0.xsd"
        >

    <services>        

        <service id="periodic_service" class="PeriodicService">
            <tag name="litgroup_event_loop.periodic" interval="1s" method="tick"/>
        </service>

    </services>

</container>

Now, when event loop will be running PeriodicService::tick() will be called with period in 1 second.
