Route Definition Enhancements in Laravel with Enum Integration

Laravel continues to embrace PHP's enum functionality, now extending support directly to route definitions. This update eliminates the need for explicit value access when using enums in routes, resulting in cleaner, more maintainable code while preserving type safety.

When working with route names or domains, you can now pass enum cases directly to Laravel's routing methods, streamlining your route definitions without sacrificing the benefits of enum type checking.

enum RouteSection: string
{
    case Admin = 'admin';
    case Client = 'client';
    case Public = 'public';
}
 
Route::prefix(RouteSection::Admin)
    ->group(function () {
        // Admin routes
    });

Let's explore a practical example of organizing routes in a multi-portal application:

<?php
 
namespace App\Routing;
 
use App\Http\Controllers\Portal;
 
enum PortalType: string
{
    case Student = 'student.university.edu';
    case Faculty = 'faculty.university.edu';
    case Admin = 'admin.university.edu';
}
 
enum PortalSection: string
{
    case Dashboard = 'dashboard';
    case Resources = 'resources';
    case Profile = 'profile';
}
 
// Route configuration
Route::domain(PortalType::Student)
    ->middleware(['auth', 'student'])
    ->group(function () {
        Route::get('/', [Portal\StudentController::class, 'index'])
            ->name(PortalSection::Dashboard);
 
        Route::get('/materials', [Portal\ResourceController::class, 'index'])
            ->name(PortalSection::Resources);
 
        Route::get('/profile', [Portal\ProfileController::class, 'show'])
            ->name(PortalSection::Profile);
});
 
Route::domain(PortalType::Faculty)
    ->middleware(['auth', 'faculty'])
    ->group(function () {
        // Faculty portal routes using the same enums
        Route::get('/', [Portal\FacultyController::class, 'index'])
            ->name(PortalSection::Dashboard);
    });

This direct enum support in route definitions improves code readability while maintaining the type safety and autocompletion benefits of PHP enums.
