This Yii framework package provides the application class, as well as the events
and handlers needed to interact with HTTP. The package is implemented using
[PSR-7](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-7-http-message.md) interfaces.

## Requirements

- PHP 8.0 or higher.

## Installation

The package could be installed with [Composer](https://getcomposer.org):

```shell
composer require yiisoft/yii-http
```

## General usage

In case you use one of the Yii 3 standard application templates, then the application is already configured
there and is running using [yiisoft/yii-runner-http](https://github.com/yiisoft/yii-runner-http) package.

If not, then use one of the HTTP runners that is suitable for your environment:

- [HTTP](https://github.com/yiisoft/yii-runner-http)
- [RoadRunner](https://github.com/yiisoft/yii-runner-roadrunner)

and create an entry script as described in readme of the packages.

If you do not use Yii HTTP runners, then the code for launching the application in your entry script may look like this:

```php
use Yiisoft\Yii\Http\Application;
use Yiisoft\Yii\Http\Handler\NotFoundHandler;
use Yiisoft\Yii\Http\Handler\ThrowableHandler;

/**
* @var Psr\EventDispatcher\EventDispatcherInterface $eventDispatcher
* @var Psr\Http\Message\ResponseFactoryInterface $responseFactory
* @var Psr\Http\Message\ServerRequestInterface $request
* @var Yiisoft\ErrorHandler\Middleware\ErrorCatcher $errorCatcher
* @var Yiisoft\Middleware\Dispatcher\MiddlewareDispatcher $dispatcher
*/

$fallbackHandler = new NotFoundHandler($responseFactory);
$application = new Application($dispatcher, $eventDispatcher, $fallbackHandler);

try {
$application->start();
$response = $application->handle($request);
// Emit a response.
} catch (Throwable $throwable) {
$handler = new ThrowableHandler($throwable);
$response = $errorCatcher->process($request, $handler);
// Emit a response with information about the error.
} finally {
$application->afterEmit($response ?? null);
$application->shutdown();
}
```
