How to install
composer install corviz/router
Router facade (singleton)
This is the most common use scenario. That is why we provide a ready-to-use facade.
First, you have to declare you application routes:
use Corviz\Router\Facade\RouterFacade as Router; /* * Application routes */ Router::get('/', function() { return 'Hello world!'; }); Route::get('/user/(\d+)', function(int $id){ return "Show information for user $id"; });
Then, execute and output the results.
echo Router::dispatch(); !Router::found() && http_response_code(404);
Note: Router::dispatch() returns the value that was returned by controllers (a string in this example).
Controller classes
If you use classes as controllers, use an array as the second parameter in the route declaration.
Example controller class
namespace MyApplication; class UserController { public function show(int $id) { //Search for user information in the database //... return $user; } }
Route for the controller above.
Router::get('/user/(\d+)', [\MyApplication\User::class, 'show']);
Supported methods
The supported methods for route declarations are: get
,post
,put
,patch
,delete
,options
,head
or any
Each represents one HTTP method, except for any
, which will attend to all of them
use Corviz\Router\Facade\RouterFacade as Router; Router::get('/user/(\d+)', function(int $id) { /*...*/ }); Router::post('/user/new', function() { /*...*/ }); Router::delete('/user/(\d+)', function(int $id) { /*...*/ });
Middlewares
Middlewares are responsible for request pre and post processing.
We will accept callables or classes that extends Corviz\Router\Middleware
as middlewares for your application
use Corviz\Router\Middleware; class AcceptJsonMiddleware extends Middleware { public function handle(Closure $next): mixed { //Interrupts in case wrong content-type was sent if (!$_SERVER['CONTENT_TYPE'] != 'application/json') { return 'Invalid content type'; } return $next(); //Proceed with the request } }
To assign a Middleware do as follows:
use Corviz\Router\Facade\RouterFacade as Router; Router::any( /*...*/ ) ->middleware(AcceptJsonMiddleware::class);
Or if you want to assign multiple middlewares at once:
use Corviz\Router\Facade\RouterFacade as Router; Router::any( /*...*/ ) ->middleware([Middleware1::class, Middleware2::class]);
Grouping
To group multiple routes, you must first use the prefix
method, then just use group
with a callable
carrying those sub-routes. For example:
use Corviz\Router\Facade\RouterFacade as Router; Router::prefix('user')->group(function() { Router::get('list', function() { /**/ }); Router::get('(\d+)', function(int $id) { /**/ }); Router::post('new', function() { /**/ }); Router::patch('(\d+)/update', function(int $id) { /**/ }); Router::delete('(\d+)/delete', function(int $id) { /**/ }); });
This will create the following routes:
- user/list
- user/(\d+)
- user/new
- user/(\d+)/update
- user/(\d+)/delete
Middleware for groups
You can assign middlewares for multiple routes at once by using the middleware
method between prefix
and group
use Corviz\Router\Facade\RouterFacade as Router; Router::prefix('api') ->middleware(CheckTokenMiddleware::class) ->middleware(AcceptJsonMiddleware::class) ->group(function() { /* ... */ });
Determine the current path and method manually
The 'dispatch()' method reads 'REQUEST_METHOD' and 'REQUEST_URI' indexes from $_SERVER superglobal to determine which route will be executed.
However, you may want to inform it manually. If so, just feed it as follows:
$method = 'GET'; //or POST, PUT, PATCH, DELETE... $path = 'users/1/show'; $output = Router::dispatch($method, $path);
Multiple routers
If you have to work with multiple routers for whatever reason, all you have to do is the class Dispatcher, instead of the router facade
use Corviz\Router\Dispatcher; $router = new Dispatcher(); $router2 = new Dispatcher(); $router3 = new Dispatcher(); //so on...
Then, register and execute the routes as usual:
$router1->get('route1', /* ... */); $router1->prefix('group1')->group(function() use (&$router1){ $router1->get('route2', /* ... */); $router1->get('route3', /* ... */); }); echo $router1->dispatch(); !$router1->found() && http_response_code(404);
