Installation

composer require bermudaphp/router

Usage

use Bermuda\Router\Routes;

$routes = new Routes;
$router = Router::fromDnf($routes);

$routes->addRoute(
    RouteRecord::get('home', '/hello/[name]', static function(string $name): void {
        echo sprintf('Hello, %s!', $name)
    })
); 

$route = $router->match($_SERVER['REQUEST_URI'], $_SERVER['REQUEST_METHOD']);
if (!route) {
    // route not found logics
}

call_user_func($route->handler, $route->params['name']);

Route path generation

echo $router->generate('home', ['name' => 'Jane Doe']); // Output /hello/Jane%20Doe

Usage with PSR-15

$pipeline = new \Bermuda\Pipeline\Pipeline();
$factory = new \Bermuda\MiddlewareFactory\MiddlewareFactory($container, $responseFactory);

class Handler implements RequestHandlerInterface
{
   public function handle(ServerRequestInterface $request): ResponseInterface
   {
       return new TextResponse(sprintf('Hello, %s!', $request->getAttribute('name')))
   }
};

$routes->addRoute(
    RouteRecord::get('home', '/hello/[name:[a-z]]', Handler::class)
); 

$pipeline->pipe($factory->make(Bermuda\Router\Middleware\MatchRouteMiddleware::class));
$pipeline->pipe($factory->make(Bermuda\Router\Middleware\DispatchRouteMiddleware::class)
    ->setFallbackHandler($container->get(Bermuda\Router\Middleware\RouteNotFoundHandler::class)));
 
$response = $pipeline->handle($request);

send($response)

Get current route data

class Handler implements RequestHandlerInterface
{
   public function handle(ServerRequestInterface $request): ResponseInterface
   {
       $route = $request->getAttribute('Bermuda\Router\Middleware\RouteMiddleware')->route; // MatchedRoute instance
   }
}; 

RouteRecord HTTP verbs helpers

RouteRecord::get(string $name, string $path, mixed $handler): RouteRecord ;
RouteRecord::post(string $name, string $path, mixed $handler): RouteRecord ;
RouteRecord::patch(string $name, string $path, mixed $handler): RouteRecord ;
RouteRecord::put(string $name, string $path, mixed $handler): RouteRecord ;
RouteRecord::delete(string $name, string $path, mixed $handler): RouteRecord ;
RouteRecord::options(string $name, string $path, mixed $handler): RouteRecord ;
RouteRecord::head(string $name, string $path, mixed $handler): RouteRecord ;

Set attribute placeholder pattern

$routes->addRoute(RouteRecord::get('users.get, '/api/v1/users/[id:[a-zA-Z]]', static function(ServerRequestInterface $request): ResponseInterface {
    return findUser($request->getAttribute('id'));
}));

alternative:
$routes->addRoute(RouteRecord::get('users.get, '/api/v1/users/[id]', static function(ServerRequestInterface $request): ResponseInterface {
    return findUserById($request->getAttribute('id'));
})->withToken('id', '[a-zA-Z]'));

Optional attribute

$routes->addRoute(RouteRecord::get('users.get, '/api/v1/users/[?id]', static function(ServerRequestInterface $request): ResponseInterface {
    if (($id = $request->getAttribute('id')) !== null) {
        return findUserById($id);
    }
    
    return get_all_users();
}));

Predefined placeholders

id: \d+
any: .*

Other placeholders passed to path as a string without being explicitly defined will match the pattern .+

Routes Group

$group = $routes->group(name: 'api', prifix: '/api'); // set routes group

$group->addRoute(RouteRecord::get('users.get, 'users/[?id]', GetUserHandler::class));
$group->addRoute(RouteRecord::post(user.create, 'users', CreateUserHandler::class));

$group->setMiddleware([GuardMiddleware::class]) // set middleware for all routes in group
$group->setTokens(['id' => '[a-zA-Z]']) // set tokens for all routes in group


$group = $routes->group('api') // get routes group from name

Cache

Once all routes are registered in the route map and they will no longer be changed. Call the $routes->cache method to cache the route map in a php file. Then use the Routes::createFromCache('/path/to/cached/routes/filename.php') method to create a map instance with preloaded routes.

 
 $routes->cache('path/to/cached/routes/file.php');
 $routes = Routes::createFromCache('path/to/cached/routes/file.php')
 
 $router = Router::fromDnf($routes);

Cache context

If you are using a parent-context-bound closure (the use construct) as a route handler, then you must pass an array of bound variables to the Routes::createFromCache method. See example below

 $app = new App;
 $repository = new UserRepository;
 $routes->addRoute(RouteRecord::get('user.get', '/users/[id]', static function(ServerRequest $request) use ($app, $repository): ResponseInterface {
    return $app->respond(200, $repository->findById($request->getAttribute('id')));
 }));

 $routes->cache('path/to/cached/routes/file.php');
 $routes = Routes::createFromCache('path/to/cached/routes/file.php', compact('app', 'repository'));

Cache limitations

Currently, the caching implementation does not allow caching routes using object instances and callback functions based on object instances.
