Yii RoadRunner Runner

The package contains a bootstrap for running Yii3 applications using RoadRunner.

Requirements

• PHP 8.1 or higher.

Installation

The package could be installed with Composer:

composer require yiisoft/yii-runner-roadrunner

General usage

Get RoadRunner:

./vendor/bin/rr get

Create worker.php in your application root directory:

use Yiisoft\Yii\Runner\RoadRunner\RoadRunnerHttpApplicationRunner;

ini_set('display_errors', 'stderr');

require_once __DIR__ . '/autoload.php';

(new RoadRunnerHttpApplicationRunner(
    rootPath: __DIR__, 
    debug: $_ENV['YII_DEBUG'], 
    checkEvents: $_ENV['YII_DEBUG'], 
    environment: $_ENV['YII_ENV']
))->run();

Specify it in your .rr.yaml:

version: '3'
server:
    command: "php ./worker.php"

rpc:
    listen: tcp://127.0.0.1:6001

http:
    address: :8082
    pool:
        num_workers: 8
        # Debug mode for the pool. In this mode, pool will not pre-allocate the worker.
        # Worker (only 1, num_workers ignored) will be allocated right after the request arrived.
        debug: false
    middleware: ["static", "headers"]
    static:
        dir:   "./public"
        forbid: [".php", ".htaccess"]
    headers:
        response:
            "Cache-Control": "no-cache"

logs:
    mode: production
    level: warn

Note: Official configuration reference. You can also activate RoadRunner schema in your IDE to get autocompletion hints.

Run RoadRunner with the config specified:

./rr serve

Additional configuration

By default, the RoadRunnerHttpApplicationRunner is configured to work with Yii application templates and follows the config groups convention.

You can override the default configuration using constructor parameters and immutable setters.

Constructor parameters

$rootPath — the absolute path to the project root.

$debug — whether the debug mode is enabled.

$checkEvents — whether check events' configuration.

$environment — the environment name.

$bootstrapGroup — the bootstrap configuration group name.

$eventsGroup — the events' configuration group name.

$diGroup — the container definitions' configuration group name.

$diProvidersGroup — the container providers' configuration group name.

$diDelegatesGroup — the container delegates' configuration group name.

$diTagsGroup — the container tags' configuration group name.

$paramsGroup — the config parameters group name.

$nestedParamsGroups — configuration group names that are included into config parameters group. This is needed for recursive merge parameters.

$nestedEventsGroups — configuration group names that are included into events' configuration group. This is needed for reverse and recursive merge events' configurations.

Immutable setters

If the configuration instance settings differ from the default you can specify a customized configuration instance:

/**
 * @var Yiisoft\Config\ConfigInterface $config
 * @var Yiisoft\Yii\Runner\RoadRunner\RoadRunnerHttpApplicationRunner $runner
 */

$runner = $runner->withConfig($config);

The default container is Yiisoft\Di\Container. But you can specify any implementation of the Psr\Container\ContainerInterface:

/**
 * @var Psr\Container\ContainerInterface $container
 * @var Yiisoft\Yii\Runner\RoadRunner\RoadRunnerHttpApplicationRunner $runner
 */

$runner = $runner->withContainer($container);

In addition to the error handler that is defined in the container, the runner uses a temporary error handler. A temporary error handler is needed to handle the creation of configuration and container instances, then the error handler configured in your application configuration will be used.

By default, the temporary error handler uses HTML renderer and logging to a file. You can override this as follows:

/**
 * @var Psr\Log\LoggerInterface $logger
 * @var Yiisoft\ErrorHandler\Renderer\PlainTextRenderer $renderer
 * @var Yiisoft\Yii\Runner\RoadRunner\RoadRunnerHttpApplicationRunner $runner
 */

$runner = $runner->withTemporaryErrorHandler(
    new Yiisoft\ErrorHandler\ErrorHandler($logger, $renderer),
);

You can also use your own implementation of the Spiral\RoadRunner\Http\PSR7WorkerInterface (default is a Spiral\RoadRunner\Http\PSR7Worker):

/**
 * @var Spiral\RoadRunner\Http\PSR7WorkerInterface $psr7Worker
 * @var Yiisoft\Yii\Runner\RoadRunner\RoadRunnerHttpApplicationRunner $runner
 */

$runner = $runner->withPsr7Worker($psr7Worker);

Temporal

Temporal is a distributed, scalable, durable, and highly available orchestration engine used to execute asynchronous long-running business logic in a scalable and resilient way.

Explore more about Temporal on the official website and in the SDK repository.

If you want to add support for Temporal you need to install the SDK and configure workflows and activities as described below.

Installation

composer require temporal/sdk

Configuration

Temporal has at least two main class types: Activity and Workflow. Any activity must have the attribute \Temporal\Activity\ActivityInterface:

namespace App\Activity;

#[\Temporal\Activity\ActivityInterface]
class MyActivity
{
   // ...
}

Any workflow must have the attribute \Temporal\Workflow\WorkflowInterface.

namespace App\Workflow;

#[\Temporal\Workflow\WorkflowInterface]
class MyWorkflow
{
   // ...
}

Configure Temporal engine to make it able to work with your activities and workflows in the params.php:

// config/common/params.php

return [
    'yiisoft/yii-runner-roadrunner' => [
        'temporal' => [
            'enabled' => true,
            'host' => 'localhost:7233', // host of Temporal engine
            'workflows' => [
                \App\Workflow\MyWorkflow::class,
            ],
            'activities' => [
                \App\Activity\MyActivity::class,
            ],
        ],
    ],
]

If you use another container instead of yiisoft/di, make sure that \Yiisoft\Yii\Runner\RoadRunner\Temporal\TemporalDeclarationProvider is registered and returns all of your workflows and activities.

The last thing is to call withTemporalEnabled(true) on the \Yiisoft\Yii\Runner\RoadRunner\RoadRunnerHttpApplicationRunner in the public/index.php:

(new RoadRunnerHttpApplicationRunner())
    ->withTemporalEnabled(true)
    ->run();
