Route Package Gap Analysis

Overview

This document analyzes the gaps between our Route package's actual implementation and Laravel's routing functionality, identifying areas that need implementation or documentation updates.

Implementation Gaps

1. Missing Laravel Features

// Documented but not implemented:

// 1. Route Model Binding
class RouteModelBinding {
  // Need to implement:
  void bind(String key, Type type);
  void bindWhere(String key, Type type, Function where);
  void bindCallback(String key, Function callback);
  void scopeBindings();
}

// 2. Route Caching
class RouteCache {
  // Need to implement:
  Future<void> cache();
  Future<void> clear();
  bool isEnabled();
  Future<void> reload();
  Future<void> compile();
}

// 3. Route Fallbacks
class RouteFallback {
  // Need to implement:
  void fallback(dynamic action);
  void missing(Function callback);
  void methodNotAllowed(Function callback);
  void notFound(Function callback);
}

2. Missing Route Features

// Need to implement:

// 1. Route Constraints
class RouteConstraints {
  // Need to implement:
  void pattern(String name, String pattern);
  void patterns(Map<String, String> patterns);
  bool matches(String name, String value);
  void whereNumber(List<String> parameters);
  void whereAlpha(List<String> parameters);
  void whereAlphaNumeric(List<String> parameters);
  void whereUuid(List<String> parameters);
}

// 2. Route Substitutions
class RouteSubstitution {
  // Need to implement:
  void substitute(String key, dynamic value);
  void substituteBindings(Map<String, dynamic> bindings);
  void substituteImplicit(Map<String, Type> bindings);
  String resolveBinding(String key);
}

// 3. Route Rate Limiting
class RouteRateLimiting {
  // Need to implement:
  void throttle(String name, int maxAttempts, Duration decay);
  void rateLimit(String name, int maxAttempts, Duration decay);
  void forUser(String name, int maxAttempts, Duration decay);
  void exempt(List<String> routes);
}

3. Missing Group Features

// Need to implement:

// 1. Group Attributes
class RouteGroupAttributes {
  // Need to implement:
  void controller(Type controller);
  void namespace(String namespace);
  void name(String name);
  void domain(String domain);
  void where(Map<String, String> patterns);
}

// 2. Group Middleware
class RouteGroupMiddleware {
  // Need to implement:
  void aliasMiddleware(String name, Type middleware);
  void middlewarePriority(List<String> middleware);
  void pushMiddlewareToGroup(String group, String middleware);
  List<String> getMiddlewareGroups();
}

// 3. Group Resources
class RouteGroupResources {
  // Need to implement:
  void resources(Map<String, Type> resources);
  void apiResources(Map<String, Type> resources);
  void singleton(String name, Type controller);
  void apiSingleton(String name, Type controller);
}

Documentation Gaps

1. Missing API Documentation

// Need to document:

/// Binds route model.
/// 
/// Example:
/// ```dart
/// router.bind('user', User, (value) async {
///   return await User.find(value);
/// });
/// ```
void bind(String key, Type type, [Function? callback]);

/// Defines route pattern.
///
/// Example:
/// ```dart
/// router.pattern('id', '[0-9]+');
/// router.get('users/{id}', UsersController)
///   .where('id', '[0-9]+');
/// ```
void pattern(String name, String pattern);

2. Missing Integration Examples

// Need examples for:

// 1. Route Model Binding
router.bind('user', User);

router.get('users/{user}', (User user) {
  return user; // Auto-resolved from ID
});

// 2. Route Rate Limiting
router.middleware(['throttle:60,1'])
  .group(() {
    router.get('api/users', UsersController);
  });

// 3. Route Resources
router.resources({
  'photos': PhotoController,
  'posts': PostController
});

3. Missing Test Coverage

// Need tests for:

void main() {
  group('Route Model Binding', () {
    test('resolves bound models', () async {
      router.bind('user', User);
      
      var response = await router.dispatch(
        Request('GET', '/users/1')
      );
      
      expect(response.data, isA<User>());
      expect(response.data.id, equals('1'));
    });
  });
  
  group('Route Caching', () {
    test('caches compiled routes', () async {
      await router.cache();
      
      var route = router.match(
        Request('GET', '/users/1')
      );
      
      expect(route, isNotNull);
      expect(route!.compiled, isTrue);
    });
  });
}

Implementation Priority

1. High Priority

   • Route model binding (Laravel compatibility)
   • Route caching (Laravel compatibility)
   • Route constraints

2. Medium Priority

   • Route substitutions
   • Route rate limiting
   • Group resources

3. Low Priority

   • Route fallbacks
   • Additional constraints
   • Performance optimizations

Next Steps

1. Implementation Tasks

   • Add integration examples

3. Testing Tasks

   • Add binding tests
   • Add caching tests
   • Add constraint tests
   • Add resource tests
