README

A highly efficient and flexible routing package for PHP, designed to support modern web applications with minimal overhead.

Features

Fast Route Matching: Utilizes a trie data structure for efficient route matching.
Flexible Handlers: Supports various types of handlers (closures, arrays, strings).
PSR-7/PSR-15 Compliant: Compatible with PSR-7 HTTP messages and PSR-15 middleware.
Global Middleware: Application-wide middleware via $router->use().
Middleware Groups & Aliases: Reusable middleware configurations with named groups.
Customizable Invocation Strategies: Define how route handlers are invoked.
Dependency Injection: Integrates with PSR-11 containers for automatic dependency resolution.
Dynamic and Static Routes: Easily define and handle both dynamic and static routes.
Attribute-Based Routing: Define routes using PHP 8 attributes on controller methods.

Requirements

PHP 8.2 or later

Usage

Install the package using Composer:

composer require denosyscore/routing

Install a PSR-7 implementation, such as Laminas Diactoros:

composer require laminas/laminas-diactoros

Here's a simple example of how to define routes and handle requests:

// Create a new router instance
$router = new Denosys\Routing\Router();

// Define a route
$router->get('/', function (): ResponseInterface {
    $response = new Laminas\Diactoros\Response();
    $response->getBody()->write('Hello, World!');
    return $response;
});

// Create Request
$request = Laminas\Diactoros\ServerRequestFactory::fromGlobals();

// Dispatch the request
$response = $router->dispatch($request);

// Output the response
echo $response->getBody();

Middleware

The Router supports PSR-15 middleware with built-in execution via the Dispatcher.

Global Middleware

Use $router->use() to register middleware that runs on every request:

// Global middleware runs on ALL routes
$router->use(LoggingMiddleware::class);
$router->use(CorsMiddleware::class);

// Supports arrays
$router->use([ErrorHandlerMiddleware::class, SessionMiddleware::class]);

// Routes defined before or after - doesn't matter
$router->get('/users', 'UserController@index');
$router->get('/posts', 'PostController@index');

Global middleware:

Executes before any route-specific middleware (outermost layer)
Applied at dispatch time, so order of use() vs route definitions doesn't matter
Supports class strings, aliases, or middleware instances

Route Middleware

Add middleware to specific routes:

// Single middleware
$router->get('/admin', 'AdminController@index')
       ->middleware('auth');

// Multiple middleware
$router->get('/api/users', 'UserController@index')
       ->middleware(['auth', 'throttle']);

// Chained middleware (applies to next route only)
$router->middleware('auth')
       ->get('/dashboard', 'DashboardController@index');

Middleware Groups and Aliases

// Register aliases
$router->aliasMiddleware('auth', AuthMiddleware::class);
$router->aliasMiddleware('throttle', ThrottleMiddleware::class);

// Register groups (can reference aliases or other groups)
$router->middlewareGroup('web', ['session', 'csrf', 'cookies']);
$router->middlewareGroup('api', ['throttle', 'auth']);

// Use aliases/groups on routes
$router->get('/dashboard', 'DashboardController@index')
       ->middleware('web');

$router->get('/api/users', 'UserController@index')
       ->middleware('api');

// Modify existing groups
$router->prependMiddlewareToGroup('web', 'logging');
$router->appendMiddlewareToGroup('api', 'cors');

Route Groups with Middleware

Apply middleware to all routes in a group:

$router->middleware('auth')->group('/admin', function ($group) {
    $group->get('/dashboard', 'AdminController@dashboard');
    $group->get('/users', 'AdminController@users');
});

Excluding Middleware

Use withoutMiddleware() to exclude specific middleware from a route:

// Exclude from route middleware
$router->get('/test', 'TestController@index')
       ->middleware(['auth', 'logging', 'throttle'])
       ->withoutMiddleware('logging');

// Exclude inherited group middleware
$router->middleware(['auth', 'admin'])->group('/admin', function ($group) {
    $group->get('/dashboard', 'AdminController@dashboard');  // Has auth + admin
    $group->get('/public', 'AdminController@public')
          ->withoutMiddleware('auth');                       // Only has admin
});

// Exclude multiple middleware
$route->withoutMiddleware(['logging', 'throttle']);

Retrieving Middleware Metadata

$routes = $router->getRouteCollection()->all();
$route = reset($routes);
$middleware = $route->getMiddleware(); // ['auth', 'throttle']

Adding Routes

You can add routes using various HTTP methods:

$router->get('/user/{id}', 'UserController@show');
$router->post('/user', 'UserController@store');
$router->put('/user/{id}', 'UserController@update');
$router->delete('/user/{id}', 'UserController@destroy');
$router->patch('/user/{id}', 'UserController@patch');
$router->options('/user', 'UserController@options');
$router->any('/any-method', 'AnyController@handle');
