HTTP Method Routes

Laravel supports different request types:

});

Post:

Route::post('/submit', function () {
    return "Form Submitted";
});

Route::put('/update', function () {
    return "Updated";
});

Delete:

Route::delete('/delete', function () {
    return "Deleted";
});

Named Routes

Assign a name to route

Route::get('/home', function () {
    return "Home";
})->name('home');

Route Groups

Groups multiple routes together

Route::prefix('admin')->group(function () {
    Route::get('/dashboard', function () {
        return "Admin Dashboard";
    });
});

Route with controller

Instead of writing logic in route, use a controller.

Route::get('/users', [UserController::class, 'index']);
