PSR-15 middleware pipeline for the Componenta framework.

Installation
------------

[](#installation)

```
composer require componenta/pipeline
```

The package declares `Componenta\Http\Middleware\PipelineConfigProvider` in `extra.componenta.config-providers`. When `componenta/composer-plugin` is installed, the provider is added to the generated provider list automatically.

Related Packages
----------------

[](#related-packages)

PackageWhy it matters here`psr/http-server-middleware`Defines `MiddlewareInterface` and `RequestHandlerInterface`.`componenta/app-http`Runs HTTP applications on top of the pipeline; concrete middleware and response emission live in separate HTTP packages.`componenta/router`Usually sits near the end of the HTTP pipeline.`componenta/middleware-factory`Creates middleware from strings, classes, groups, and callables.Usage
-----

[](#usage)

### As a top-level handler

[](#as-a-top-level-handler)

```
use Componenta\Http\Middleware\Pipeline;

$pipeline = new Pipeline(
    [$errorMiddleware, $authMiddleware, $routerMiddleware],
    fallbackHandler: $notFoundHandler,
);

$response = $pipeline->handle($request);
```

If no `fallbackHandler` is supplied, `EmptyPipelineHandler` is installed and throws `RuntimeException` on invocation — this surfaces misconfiguration of an empty pipeline.

### Nested pipelines

[](#nested-pipelines)

A pipeline is itself a middleware, so pipelines compose:

```
$api = new Pipeline([$apiAuth, $apiRouter]);
$web = new Pipeline([$sessionMiddleware, $webRouter]);

$app = new Pipeline([$errorMiddleware], $notFoundHandler)
    ->pipe($api)
    ->pipe($web);
```

### Via the factory

[](#via-the-factory)

```
$pipeline = $factory->createMiddlewarePipeline(
    [$auth, $router],
    $notFoundHandler,
);
```

Behavior
--------

[](#behavior)

- Middleware execute in registration order (FIFO).
- `pipe()` returns a new pipeline; the original is not modified.
- Returning a response from a middleware without calling the next handler halts the chain.
- Exceptions from middleware and terminal handlers propagate unchanged.

Errors
------

[](#errors)

ConditionExceptionNon-middleware element in constructor / `pipe()``InvalidArgumentException`Pipeline appended to itself via `pipe()``RuntimeException`Pipeline passed as its own handler to `process()``RuntimeException`Empty pipeline invoked without a custom fallback`RuntimeException`
