Short description

Build one complete app: user registration/login, protected CRUD for a resource (posts/products), and a JSON API with status codes.

Steps

1. Create migrations for users and posts.
2. Implement registration/login.
3. Add web CRUD + API CRUD.
4. Protect routes with filters.
5. Test with Postman and deploy.

Final project scope

1. Auth (register/login/logout)
2. Password hashing + session/JWT
3. Resource CRUD with validation
4. REST API endpoints + Postman tests
5. CSRF/XSS basics + flash messages
6. Deploy-ready .env + migrations

Suggested API routes

$routes->group('api', static function ($routes) {
    $routes->post('login', 'ApiAuth::login');
    $routes->resource('posts', ['controller' => 'ApiPosts', 'filter' => 'jwt']);
});
