charset=UTF-8 Content-Transfer-Encoding: 8bit - Erstelle die Datei `CLEAN_CODE_REFACTORING.md`, die die Ziele und Prinzipien des Clean Code Refactorings beschreibt. - Implementiere neue Klassen wie `UserRepository`, `WebSocketMessageHandler`, `MessageValidator`, `ConfigurationManager` und `ChatUserClean`, um die Lesbarkeit, Wartbarkeit und Testbarkeit des Codes zu verbessern. - Füge Methoden zur Fehlerbehandlung, zur Verwendung von Konstanten und zur Anwendung des Factory Patterns hinzu. - Aktualisiere die `CMakeLists.txt`, um die neuen Quellcodedateien einzuschließen. - Optimiere die `ChatRoom`- und `ChatUser`-Klassen, um die neuen Strukturen und Prinzipien zu integrieren. - Füge einen Migrationsleitfaden und Metriken zur Bewertung der Codequalität hinzu. --- CLEAN_CODE_REFACTORING.md | 181 +++++++++++++++++++ CMakeLists.txt | 5 + src/core/chat_room.cpp | 15 +- src/core/chat_user.cpp | 34 ++++ src/core/chat_user.h | 1 + src/core/chat_user_clean.cpp | 240 +++++++++++++++++++++++++ src/core/chat_user_clean.h | 121 +++++++++++++ src/core/configuration_manager.cpp | 191 ++++++++++++++++++++ src/core/configuration_manager.h | 68 +++++++ src/core/message_validator.cpp | 124 +++++++++++++ src/core/message_validator.h | 87 +++++++++ src/core/ssl_server.cpp | 95 +++++++++- src/core/user_repository.cpp | 178 ++++++++++++++++++ src/core/user_repository.h | 74 ++++++++ src/core/websocket_message_handler.cpp | 109 +++++++++++ src/core/websocket_message_handler.h | 56 ++++++ 16 files changed, 1576 insertions(+), 3 deletions(-) create mode 100644 CLEAN_CODE_REFACTORING.md create mode 100644 src/core/chat_user_clean.cpp create mode 100644 src/core/chat_user_clean.h create mode 100644 src/core/configuration_manager.cpp create mode 100644 src/core/configuration_manager.h create mode 100644 src/core/message_validator.cpp create mode 100644 src/core/message_validator.h create mode 100644 src/core/user_repository.cpp create mode 100644 src/core/user_repository.h create mode 100644 src/core/websocket_message_handler.cpp create mode 100644 src/core/websocket_message_handler.h diff --git a/CLEAN_CODE_REFACTORING.md b/CLEAN_CODE_REFACTORING.md new file mode 100644 index 0000000..d643d5f --- /dev/null +++ b/CLEAN_CODE_REFACTORING.md @@ -0,0 +1,181 @@ +# Clean Code Refactoring - YourChat + +## 🎯 Ziel +Das YourChat-Projekt wurde nach Clean Code Prinzipien refaktoriert, um: +- **Lesbarkeit** zu verbessern +- **Wartbarkeit** zu erhöhen +- **Testbarkeit** zu ermöglichen +- **Erweiterbarkeit** zu fördern + +## 🔧 Implementierte Clean Code Prinzipien + +### 1. **Single Responsibility Principle (SRP)** +Jede Klasse hat nur eine Verantwortlichkeit: + +- **`UserRepository`**: Nur Datenbankoperationen für User +- **`WebSocketMessageHandler`**: Nur WebSocket-Kommunikation +- **`MessageValidator`**: Nur Nachrichtenvalidierung +- **`ConfigurationManager`**: Nur Konfigurationsverwaltung + +### 2. **Dependency Injection** +Abhängigkeiten werden über Konstruktoren injiziert: + +```cpp +// Vorher: ChatUser macht direkte Datenbankabfragen +ChatUser(std::shared_ptr parent, std::string name, ...);

+auto webSocketUser = ChatUserClean::createWebSocketUser(room, name, wsi, repository); +``` + +### 4. **Meaningful Names** +Selbsterklärende Namen: + +```cpp +// Vorher +_wsi, _parent, _msgQueue + +// Nachher +_webSocket, _room, _messageQueue +``` + +### 5. **Small Functions** +Funktionen mit maximal 20 Zeilen: + +```cpp +// Vorher: 100+ Zeilen Konstruktor +ChatUser::ChatUser(...) { /* 100+ Zeilen */ } + +// Nachher: Aufgeteilt in kleine Funktionen +void initializeUser();
