Routing Fundamentals

Routing in Laravel

Routes are defined in routes/web.php for web routes and routes/api.php for API routes.

use Illuminate\Support\Facades\Route;

Route::get("/", function () {
    return view("welcome");
});

Route::get("/users/{id}", function (string $id) {
    return "User ".$id;
})->name("users.show");

Route Parameters

// Required parameters
Route::get("/posts/{post}", [PostController::class, "show"]);

// Optional parameters
Route::get("/search/{query?}", function (?string $query = null) {
    return "Searching: ".($query ?? "all");
});

// Regular expression constraints
Route::get("/users/{id}", function (string $id) {
    //
})->where("id", "[0-9]+");

Named Routes

Route::get("/profile", [ProfileController::class, "show"])->name("profile");

// Generate URLs
$url = route("profile");
$url = route("users.show", ["id" => 5]);

Route Groups

Route::middleware(["auth"])->prefix("admin")->group(function () {
    Route::get("/dashboard", [AdminController::class, "dashboard"]);
    Route::resource("users", UserController::class);
});

Laravel 13: Route Caching

Laravel 13 supports php artisan route:cache with improved serialization and Folio integration. Use php artisan route:list to inspect all registered routes.
