Marwa Router

Marwa Router is a framework-agnostic routing library for PHP 8.2+ built on top of league/route. It combines PHP 8 attributes, a fluent route builder, PSR-7 request handling, PSR-15 middleware integration, and small convenience helpers for responses, input access, route inspection, and signed URLs.

Why Marwa Router

Keep route definitions close to controller code with native PHP attributes
Register routes fluently when you want explicit bootstrap logic
Stay compatible with PSR-7, PSR-15, PSR-16, and PSR-11 components
Attach middleware, host constraints, parameter rules, and throttling per route or controller
Use small utilities for JSON/HTML responses, request input, URL generation, and route inspection

Stability

This package follows semantic versioning for its documented public API under src/. Backward-compatible additions may appear in minor releases. Behavioral breaks, constructor signature changes, or renamed public methods belong in major releases and should be called out in CHANGELOG.md.

Features

Attribute routing with #[Route], #[Prefix], #[Where], #[Domain], #[UseMiddleware], #[GroupMiddleware], and #[Throttle]
Fluent route registration with grouping, naming, middleware, domain, constraints, and throttling
Optional trailing-slash matching
Direct route mapping with map() and a fluent registrar for grouped definitions
PSR-11 container integration for controller and middleware resolution
PSR-16-backed throttling middleware
Optional PSR-3 logging hooks for dispatch failures and throttling events
Trusted proxy and trusted host handling in RequestFactory
Metadata cache and compiled route bootstrap cache for faster startup
Response helpers for JSON, HTML, text, redirects, cookies, and downloads
Input helpers for query params, parsed body, route params, headers, cookies, and files
Route registry inspection with bin/routes-dump.php
Signed URL generation and verification

Requirements

PHP 8.2 or newer
Composer

Installation

composer require memran/marwa-router

Quick Start

<?php

declare(strict_types=1);

use Marwa\Router\Response;
use Marwa\Router\RouterFactory;

require __DIR__ . '/vendor/autoload.php';

$router = new RouterFactory();

$router->fluent()
    ->get('/', fn () => Response::json(['ok' => true]))
    ->name('home');

$router->setNotFoundHandler(fn () => Response::text('Route Not Found', 404));
$router->run();

Start a local server:

php -S 127.0.0.1:8000 -t examples

Complete Tutorial

1. Bootstrap the Router

<?php

declare(strict_types=1);

use Marwa\Router\Response;
use Marwa\Router\RouterFactory;

require __DIR__ . '/../vendor/autoload.php';

$router = new RouterFactory();
$router->setTrailingSlashOptional(true);
$router->setNotFoundHandler(fn () => Response::json(['message' => 'Not Found'], 404));

Use setContainer() when controllers or middleware should be resolved from a PSR-11 container. Use setCache() when throttling is enabled.

If your app runs behind a reverse proxy or load balancer, configure trust explicitly:

use Marwa\Router\Http\RequestFactory;

RequestFactory::trustProxies(['127.0.0.1', '10.0.0.0/8']);
RequestFactory::trustHosts(['example.com', '*.example.com']);

2. Register Attribute-Based Controllers

$router->registerFromDirectories([__DIR__ . '/../src/Controller'], strict: true);

strict: true is recommended in production so missing controller directories fail fast.

Example controller:

<?php

namespace App\Controller;

use Marwa\Router\Attributes\Prefix;
use Marwa\Router\Attributes\Route;
use Marwa\Router\Attributes\UseMiddleware;
use Marwa\Router\Attributes\Where;
use Marwa\Router\Response;
use Psr\Http\Message\ResponseInterface;

#[Prefix('/users', name: 'users.')]
#[Where('id', '\d+')]
final class UserController
{
    #[Route('GET', '/', name: 'index')]
    public function index(): ResponseInterface
    {
        return Response::json(['users' => []]);
    }

    #[Route('GET', '/{id}', name: 'show')]
    #[UseMiddleware(\App\Middleware\AuditMiddleware::class)]
    public function show(): ResponseInterface
    {
        return Response::json(['user' => 'example']);
    }
}

3. Add Fluent Routes

Use fluent routes for closures, bootstrap-only endpoints, or when you prefer explicit configuration. Route definitions register automatically when the definition goes out of scope; ->register() is still available when you want to force registration immediately.

$router->fluent()->group(['prefix' => '/api', 'name' => 'api.'], function ($routes): void {
    $routes->get('/ping', fn () => Response::text('pong'))
        ->name('ping');

    $routes->get('/posts/{slug}', [\App\Controller\PostController::class, 'show'])
        ->where('slug', '[a-z0-9-]+')
        ->name('posts.show');
});

Direct map() is also available when you want to register a route without the fluent builder:

$router->map(
    ['GET', 'HEAD'],
    '/health',
    static fn () => Response::json(['status' => 'ok']),
    name: 'health',
);

4. Work with Middleware and Throttling

Per-route middleware can be attached with #[UseMiddleware], #[GroupMiddleware], or ->middleware(...).

If you use throttling, provide a PSR-16 cache:

$router = new RouterFactory(cache: $cache);

Attribute example:

use Marwa\Router\Attributes\Throttle;

#[Throttle(100, 60, 'ip')]
final class ApiController
{
    #[Route('GET', '/stats', name: 'stats')]
    public function stats(): ResponseInterface
    {
        return Response::json(['ok' => true]);
    }
}

Fluent example:

$router->fluent()
    ->post('/api/login', [AuthController::class, 'login'])
    ->throttle(10, 60, 'ip')
    ->name('api.login');

Included middleware classes live in src/Middleware/:

AuthTokenMiddleware
BodyParsingMiddleware
ContentTypeMiddleware
CorsMiddleware
CsrfMiddleware
ExceptionToResponseMiddleware
MaintenanceModeMiddleware
RequestIdMiddleware
RequestGuardMiddleware
SecurityHeadersMiddleware
ThrottleMiddleware

5. Read Input Data

Marwa\Router\Http\Input and Marwa\Router\Http\HttpRequest provide ergonomic access to PSR-7 request data.

use Marwa\Router\Http\Input;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;

public function search(ServerRequestInterface $request): ResponseInterface
{
    Input::setRequest($request);

    return Response::json([
        'q' => Input::query('q'),
        'page' => Input::query('page', 1),
        'filters' => Input::only(['category', 'status']),
    ]);
}

Available helpers include get(), post(), query(), route(), header(), cookie(), file(), only(), except(), has(), and merge().

6. Generate URLs

The router keeps a route registry that can be passed to UrlGenerator.

$urls = new \Marwa\Router\UrlGenerator($router->routes());

$show = $urls->for('users.show', ['id' => 42]);
$signed = $urls->signed('users.show', ['id' => 42], 300, 'app-secret');
$valid = $urls->verify($signed, 'app-secret');

6.1 Attach a Logger

Provide any PSR-3 logger if you want visibility into missing routes or throttle violations.

$router->setLogger($logger);

7. Run the Application

$router->run();

If you need a response object without emitting it immediately, use handle():

$request = \Marwa\Router\Http\RequestFactory::fromGlobals();
$response = $router->handle($request);

For local experimentation, the repository already includes a runnable example:

php -S 127.0.0.1:8000 -t examples

8. Inspect Registered Routes

Print the route table discovered from controllers:

php bin/routes-dump.php --dir=/absolute/path/to/src/Controller

Or point the CLI to a bootstrap file that returns a configured RouterFactory instance:

php bin/routes-dump.php --bootstrap=/absolute/path/to/bootstrap.php

9. Export the Route Registry

php bin/routes-build-cache.php

This writes:

var/cache/routes.php with route metadata
var/cache/routes.compiled.php with a bootstrap callable that re-registers cacheable routes without rescanning controller files

Compiled route cache supports string handlers, [class-string, method] handlers, and middleware defined as class strings. It does not support closures or object middleware.

More Examples

Attribute Examples

Controller-level host binding and middleware:

use Marwa\Router\Attributes\Domain;
use Marwa\Router\Attributes\GroupMiddleware;
use Marwa\Router\Attributes\Prefix;
use Marwa\Router\Attributes\Route;

#[Prefix('/admin', name: 'admin.')]
#[Domain('admin.example.com')]
#[GroupMiddleware(\App\Middleware\AdminAuthMiddleware::class)]
final class AdminController
{
    #[Route('GET', '/dashboard', name: 'dashboard')]
    public function dashboard(): \Psr\Http\Message\ResponseInterface
    {
        return \Marwa\Router\Response::html('<h1>Admin</h1>');
    }
}

Single method responding to multiple HTTP verbs:

#[Route(['GET', 'POST'], '/contact', name: 'contact.submit')]
public function contact(): \Psr\Http\Message\ResponseInterface
{
    return \Marwa\Router\Response::text('Handled');
}

Fluent Route Examples

Named route with middleware and domain:

$router->fluent()
    ->get('/reports/{year}', [ReportController::class, 'show'])
    ->where('year', '\d{4}')
    ->domain('reports.example.com')
    ->middleware(\App\Middleware\AuditMiddleware::class)
    ->name('reports.show');

Route group with shared prefix, name prefix, and throttling:

$router->fluent()->group([
    'prefix' => '/api/v1',
    'name' => 'api.v1.',
    'throttle' => ['limit' => 60, 'per' => 60, 'key' => 'ip'],
], function ($routes): void {
    $routes->get('/users', [UserController::class, 'index'])
        ->name('users.index');
});

Direct map() with middleware, constraints, and a name:

$router->map(
    'GET',
    '/reports/{year}',
    [ReportController::class, 'show'],
    name: 'reports.show',
    middlewares: [\App\Middleware\AuditMiddleware::class],
    where: ['year' => '\d{4}'],
);

Request Access Examples

Using HttpRequest directly:

use Marwa\Router\Http\HttpRequest;
use Psr\Http\Message\ServerRequestInterface;

public function store(ServerRequestInterface $request): \Psr\Http\Message\ResponseInterface
{
    $input = new HttpRequest($request);

    return \Marwa\Router\Response::json([
        'method' => $input->method(),
        'url' => $input->url(),
        'host' => $input->host(),
        'subdomain' => $input->subdomainFor('example.com'),
        'all' => $input->all(),
        'only' => $input->only(['name', 'email']),
        'except' => $input->except(['password']),
        'route' => $input->routeParams(),
        'agent' => $input->header('User-Agent'),
    ]);
}

Using the static Input facade:

use Marwa\Router\Http\Input;

Input::setRequest($request);

$email = Input::post('email');
$search = Input::query('q');
$token = Input::header('X-Token');
$avatar = Input::file('avatar');
$host = Input::host();
$tenant = Input::subdomainFor('example.com');
$hasFilters = Input::has('filters.status');

Input::merge(['normalized' => true]);

Use subdomainFor() when your application knows its base domain. It is deterministic for hosts like tenant.example.com and admin.eu.example.co.uk.

Resetting the static facade in tests:

Input::reset();

Typed Bag and Form Request Examples

Using InputBag accessors:

$body = new \Marwa\Router\Http\InputBag([
    'page' => '2',
    'active' => 'true',
    'filters' => ['role' => 'editor'],
]);

$page = $body->int('page');
$active = $body->bool('active');
$filters = $body->array('filters');

Minimal FormRequest subclass:

use Marwa\Router\Http\FormRequest;

final class CreateUserRequest extends FormRequest
{
    public function rules(): array
    {
        return [
            'name' => ['required'],
            'email' => ['required'],
        ];
    }
}

Accessing data:

$form = new CreateUserRequest($request, $validator);

if (!$form->authorize()) {
    throw new RuntimeException('Forbidden');
}

$query = $form->query()->string('q');
$name = $form->body()->string('name');
$validated = $form->validate();

File Upload Example

use Laminas\Diactoros\UploadedFile;
use Marwa\Router\Http\Input;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;

public function uploadAvatar(ServerRequestInterface $request): ResponseInterface
{
    Input::setRequest($request);

    /** @var UploadedFile|null $avatar */
    $avatar = Input::file('avatar');
    if ($avatar === null || $avatar->getError() !== UPLOAD_ERR_OK) {
        return \Marwa\Router\Response::error('Upload failed', 400);
    }

    $target = __DIR__ . '/../storage/' . $avatar->getClientFilename();
    $avatar->moveTo($target);

    return \Marwa\Router\Response::success(['path' => $target], 'Uploaded');
}

Custom Middleware Example

use Laminas\Diactoros\Response\JsonResponse;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\MiddlewareInterface;
use Psr\Http\Server\RequestHandlerInterface;

final class ApiKeyMiddleware implements MiddlewareInterface
{
    public function __construct(
        private string $header = 'X-API-Key',
        private string $expected = 'secret',
    ) {}

    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
    {
        if ($request->getHeaderLine($this->header) !== $this->expected) {
            return new JsonResponse(['error' => 'Unauthorized'], 401);
        }

        return $handler->handle($request);
    }
}

Use it with attributes or fluent routes:

#[UseMiddleware(ApiKeyMiddleware::class)]
#[Route('POST', '/internal/rebuild', name: 'internal.rebuild')]
public function rebuild(): ResponseInterface
{
    return \Marwa\Router\Response::text('ok');
}

Built-in middleware can be attached the same way:

$router->map(
    'POST',
    '/api/users',
    [UserController::class, 'store'],
    middlewares: [
        \Marwa\Router\Middleware\BodyParsingMiddleware::class,
        \Marwa\Router\Middleware\SecurityHeadersMiddleware::class,
        \Marwa\Router\Middleware\RequestGuardMiddleware::class,
    ],
);

Container Integration Example

Any PSR-11 container works. One option is league/container:

use League\Container\Container;
use Marwa\Router\RouterFactory;

$container = new Container();
$container->add(\App\Service\UserService::class);
$container->add(\App\Controller\UserController::class)
    ->addArgument(\App\Service\UserService::class);
$container->add(\App\Middleware\ApiKeyMiddleware::class);

$router = new RouterFactory();
$router->setContainer($container);
$router->registerFromDirectories([__DIR__ . '/../src/Controller'], strict: true);

Once a container is attached, controller classes and middleware class names are resolved through it before falling back to direct instantiation.

Signed Download Example

$urls = new \Marwa\Router\UrlGenerator($router->routes());
$downloadUrl = $urls->signed('reports.download', ['id' => 25], 300, $_ENV['APP_KEY']);

Controller:

use Marwa\Router\UrlGenerator;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;

public function download(ServerRequestInterface $request, UrlGenerator $urls): ResponseInterface
{
    $url = (string) $request->getUri();

    if (!$urls->verify($url, $_ENV['APP_KEY'])) {
        return \Marwa\Router\Response::forbidden('Invalid or expired signature');
    }

    return \Marwa\Router\Response::download(__DIR__ . '/../reports/report-25.csv');
}

Mini CRUD Example

$router->fluent()->group(['prefix' => '/api/users', 'name' => 'users.'], function ($routes): void {
    $routes->get('/', [UserController::class, 'index'])
        ->name('index')
        ->register();

    $routes->post('/', [UserController::class, 'store'])
        ->middleware(\App\Middleware\ApiKeyMiddleware::class)
        ->name('store')
        ->register();

    $routes->get('/{id}', [UserController::class, 'show'])
        ->where('id', '\d+')
        ->name('show')
        ->register();

    $routes->patch('/{id}', [UserController::class, 'update'])
        ->where('id', '\d+')
        ->name('update')
        ->register();

    $routes->delete('/{id}', [UserController::class, 'delete'])
        ->where('id', '\d+')
        ->name('delete')
        ->register();
});

Possible controller methods:

final class UserController
{
    public function index(): \Psr\Http\Message\ResponseInterface
    {
        return \Marwa\Router\Response::json(['data' => []]);
    }

    public function store(ServerRequestInterface $request): \Psr\Http\Message\ResponseInterface
    {
        \Marwa\Router\Http\Input::setRequest($request);

        return \Marwa\Router\Response::created([
            'name' => \Marwa\Router\Http\Input::post('name'),
            'email' => \Marwa\Router\Http\Input::post('email'),
        ]);
    }

    public function show(ServerRequestInterface $request): \Psr\Http\Message\ResponseInterface
    {
        $input = new \Marwa\Router\Http\HttpRequest($request);

        return \Marwa\Router\Response::json(['id' => $input->route('id')]);
    }
}

Pagination Example

use Marwa\Router\Http\Input;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;

public function index(ServerRequestInterface $request): ResponseInterface
{
    Input::setRequest($request);

    $page = max(1, (int) Input::query('page', 1));
    $perPage = min(100, max(1, (int) Input::query('per_page', 20)));

    return \Marwa\Router\Response::json([
        'meta' => [
            'page' => $page,
            'per_page' => $perPage,
        ],
        'data' => [],
    ]);
}

JSON API Error Example

return \Marwa\Router\Response::error(
    'Validation failed',
    422,
    [
        'email' => ['The email field is required.'],
        'password' => ['The password must be at least 12 characters.'],
    ],
);

Or with a custom structure:

return \Marwa\Router\Response::json([
    'errors' => [
        ['status' => '422', 'detail' => 'The email field is required.'],
        ['status' => '422', 'detail' => 'The password must be at least 12 characters.'],
    ],
], 422);

Subdomain Routing Example

Attribute-based host binding:

use Marwa\Router\Attributes\Domain;
use Marwa\Router\Attributes\Route;

#[Domain('api.example.com')]
final class ApiStatusController
{
    #[Route('GET', '/status', name: 'api.status')]
    public function status(): \Psr\Http\Message\ResponseInterface
    {
        return \Marwa\Router\Response::json(['ok' => true]);
    }
}

Fluent host binding:

$router->fluent()
    ->get('/status', [StatusController::class, 'show'])
    ->domain('status.example.com')
    ->name('status.show')
    ->register();

Reading the current host in middleware:

final class TenantMiddleware implements \Psr\Http\Server\MiddlewareInterface
{
    public function process(
        \Psr\Http\Message\ServerRequestInterface $request,
        \Psr\Http\Server\RequestHandlerInterface $handler,
    ): \Psr\Http\Message\ResponseInterface {
        $input = new \Marwa\Router\Http\HttpRequest($request);

        return $handler->handle(
            $request->withAttribute('tenant', $input->subdomainFor('example.com'))
        );
    }
}

Reading it later in a controller:

public function dashboard(\Psr\Http\Message\ServerRequestInterface $request): \Psr\Http\Message\ResponseInterface
{
    return \Marwa\Router\Response::json([
        'host' => $request->getUri()->getHost(),
        'tenant' => $request->getAttribute('tenant'),
    ]);
}

If your app runs on more than one root domain, inject that base domain into middleware from configuration and call subdomainFor($configuredBaseDomain).

Webhook Verification Example

use Marwa\Router\Http\HttpRequest;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;

public function handleWebhook(ServerRequestInterface $request): ResponseInterface
{
    $input = new HttpRequest($request);
    $payload = (string) $request->getBody();
    $signature = (string) $input->header('X-Signature', '');
    $expected = hash_hmac('sha256', $payload, $_ENV['WEBHOOK_SECRET']);

    if (!hash_equals($expected, $signature)) {
        return \Marwa\Router\Response::forbidden('Invalid webhook signature');
    }

    return \Marwa\Router\Response::noContent();
}

Authenticated Admin Area Example

$router->fluent()->group([
    'prefix' => '/admin',
    'name' => 'admin.',
    'middleware' => [\App\Middleware\AdminAuthMiddleware::class],
], function ($routes): void {
    $routes->get('/dashboard', [AdminController::class, 'dashboard'])
        ->name('dashboard')
        ->register();

    $routes->get('/users', [AdminUserController::class, 'index'])
        ->name('users.index')
        ->register();
});

Controller-level version:

use Marwa\Router\Attributes\GroupMiddleware;
use Marwa\Router\Attributes\Prefix;

#[Prefix('/admin', name: 'admin.')]
#[GroupMiddleware(\App\Middleware\AdminAuthMiddleware::class)]
final class AdminController
{
    #[Route('GET', '/dashboard', name: 'dashboard')]
    public function dashboard(): \Psr\Http\Message\ResponseInterface
    {
        return \Marwa\Router\Response::html('<h1>Dashboard</h1>');
    }
}

PHPUnit Usage Example

use Marwa\Router\Http\RequestFactory;
use Marwa\Router\UrlGenerator;
use PHPUnit\Framework\TestCase;

final class UrlGeneratorTest extends TestCase
{
    public function testSignedUrlCanBeVerified(): void
    {
        $generator = new UrlGenerator([
            ['name' => 'users.show', 'path' => '/users/{id}'],
        ]);

        $signed = $generator->signed('users.show', ['id' => 42], 300, 'secret');

        self::assertTrue($generator->verify($signed, 'secret'));
    }

    public function testRequestFactoryBuildsQueryParams(): void
    {
        $request = RequestFactory::fromArrays(
            server: ['REQUEST_URI' => '/users?page=2', 'REQUEST_METHOD' => 'GET'],
            query: ['page' => 2],
        );

        self::assertSame(2, $request->getQueryParams()['page']);
    }
}

Response Helpers

Marwa\Router\Response exposes small factory helpers:

Response::json(...)
Response::html(...)
Response::text(...)
Response::redirect(...)
Response::download(...)
Response::success(...)
Response::error(...)
Response::notFound(...)
Response::serverError(...)
Response::unauthorized(...)
Response::forbidden(...)
Response::created(...)
Response::noContent()
Response::fromArray(...)

Example:

return Response::success(['id' => 42], 'Created', 201);

Additional examples:

return Response::json(['status' => 'ok']);
return Response::html('<p>Hello</p>');
return Response::text('Accepted', 202);
return Response::redirect('/login');
return Response::download(__DIR__ . '/report.csv');
return Response::error('Validation failed', 422, ['email' => ['Required']]);
return Response::notFound();
return Response::unauthorized();
return Response::forbidden();
return Response::serverError();
return Response::noContent();

Building a response instance manually:

$response = (new Response())
    ->status(201)
    ->header('X-Request-Id', 'abc123')
    ->cookie('session', 'token', time() + 3600, '/', '', true, true, 'Lax')
    ->body('Created')
    ->getResponse();

Creating a response from an array payload:

return Response::fromArray(['html' => '<p>Hello</p>'], 200, ['Content-Type' => 'text/html']);

URL Generator Examples

$generator = new \Marwa\Router\UrlGenerator($router->routes());

$plain = $generator->for('reports.show', ['year' => 2026]);
$withQuery = $generator->for('reports.show', ['year' => 2026, 'format' => 'csv']);
$signed = $generator->signed('reports.show', ['year' => 2026], 600, 'secret-key');
$isValid = $generator->verify($signed, 'secret-key');

Additional Patterns

RequestFactory Examples

Build a request from PHP globals:

use Marwa\Router\Http\RequestFactory;

$request = RequestFactory::fromGlobals();
$response = $router->dispatch($request);

Build a synthetic request for tests or custom runtimes:

use Marwa\Router\Http\RequestFactory;

$request = RequestFactory::fromArrays(
    server: [
        'REQUEST_METHOD' => 'POST',
        'REQUEST_URI' => '/api/users?page=2',
        'HTTP_HOST' => 'example.test',
        'HTTP_ACCEPT' => 'application/json',
        'CONTENT_TYPE' => 'application/json',
    ],
    query: ['page' => 2],
    parsedBody: ['name' => 'Marwa', 'email' => 'marwa@example.com'],
    cookies: ['session' => 'abc123'],
);

Trust reverse proxies explicitly before honoring forwarded headers:

use Marwa\Router\Http\RequestFactory;

RequestFactory::trustProxies([
    '127.0.0.1',
    '10.0.0.0/8',
]);

With trusted proxies configured, X-Forwarded-Host, X-Forwarded-Proto, and X-Forwarded-For are used to build the effective request URI and client IP. Without trusted proxies, those headers are ignored.

Trusted hosts can be restricted separately:

RequestFactory::trustHosts([
    'example.com',
    '*.example.com',
]);

Requests for other hosts will raise Marwa\Router\Exceptions\UntrustedHostException.

Clear trust configuration in tests or workers:

RequestFactory::clearTrustedProxies();
RequestFactory::clearTrustedHosts();

Redirect and Cookie Examples

Simple redirect:

return \Marwa\Router\Response::redirect('/login');

Manual response with headers and cookies:

$response = (new \Marwa\Router\Response())
    ->status(200)
    ->header('X-Frame-Options', 'DENY')
    ->addHeader('Cache-Control', 'no-store')
    ->cookie('session', 'token', time() + 3600, '/', '', true, true, 'Lax')
    ->body('Authenticated')
    ->getResponse();

return $response;

Custom Not Found Handler

HTML fallback:

$router->setNotFoundHandler(static function (): \Psr\Http\Message\ResponseInterface {
    return \Marwa\Router\Response::html('<h1>404</h1><p>Page not found.</p>', 404);
});

JSON fallback that sees the request:

use Psr\Http\Message\ServerRequestInterface;

$router->setNotFoundHandler(static function (ServerRequestInterface $request): array {
    return [
        'message' => 'Route not found',
        'path' => $request->getUri()->getPath(),
    ];
});

Controller Discovery Examples

Register a specific list of controllers:

$router->registerFromClasses([
    \App\Controller\HomeController::class,
    \App\Controller\UserController::class,
]);

Scan more than one directory:

$router->registerFromDirectories([
    __DIR__ . '/../src/Controller',
    __DIR__ . '/../modules/Billing/Controller',
], strict: true);

Route Registry Cache Example

Write the discovered route registry to disk:

$router->registerFromDirectories([__DIR__ . '/../src/Controller'], strict: true);
$router->cacheRoutesTo(__DIR__ . '/../var/cache/routes.php');

Load the exported registry in another process:

$router = new \Marwa\Router\RouterFactory();
$router->loadRoutesFrom(__DIR__ . '/../var/cache/routes.php');

This only restores the route metadata returned by routes(). It does not rebuild runtime dispatch rules by itself, so keep normal route registration in your application bootstrap.

Load the compiled bootstrap cache instead when you want faster startup:

$router = new \Marwa\Router\RouterFactory();
$router->loadCompiledRoutesFrom(__DIR__ . '/../var/cache/routes.compiled.php');

Logger Example

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$logger = new Logger('router');
$logger->pushHandler(new StreamHandler('php://stderr'));

$router->setLogger($logger);

The router logs missing routes and invalid not-found handler responses. ThrottleMiddleware logs rate-limit violations when a logger is attached to the router.

Conflict Detection Example

Conflict detection is enabled by default. You can disable it when you intentionally layer multiple route sources and want last-write behavior:

$router->enableConflictDetection(false);

Development

Install dependencies:

composer install

Useful commands:

composer test runs PHPUnit
composer test:coverage prints a text coverage report
composer analyse runs PHPStan
composer lint runs PHP-CS-Fixer in dry-run mode
composer fix applies coding-style fixes
composer validate:composer validates package metadata
composer ci runs the local validation gate

Production Notes

Keep strict_types=1 enabled in application code
Use strict: true for controller discovery in deployment builds
Provide a real shared PSR-16 cache backend when throttling matters
Prefer PSR-11 container resolution for non-trivial controllers and middleware
Return ResponseInterface, string, or array from setNotFoundHandler()
Call RequestFactory::trustProxies(...) only for proxy IPs you actually control
Call RequestFactory::trustHosts(...) to reject unexpected host headers early
Prefer subdomainFor('example.com') over naive host splitting in multi-tenant apps
Use handle() in tests, worker runtimes, and custom HTTP emitters
Attach a PSR-3 logger with setLogger() if you want visibility into missing routes and throttling events

Errors

Missing routes raise Marwa\Router\Exceptions\RouteNotFoundException when no custom not-found handler is configured
Invalid not-found handler return values raise Marwa\Router\Exceptions\InvalidNotFoundHandlerResponseException
Untrusted hosts raise Marwa\Router\Exceptions\UntrustedHostException
Route definition conflicts raise Marwa\Router\Exceptions\RouteConflictException
Invalid throttle or attribute definitions raise Marwa\Router\Exceptions\InvalidRouteDefinitionException
