🛠 Tips for Identifying and Applying Design Patterns in Projects - linhvuquach/design-patterns-practical GitHub Wiki
✅ Recognize Situations for Patterns
| Problem | Common Pattern |
|---|---|
| Object creation logic scattered | Factory |
| Need to switch between algorithms | Strategy |
| Need to delay heavy object loading | Proxy |
| Support for undo/redo | Command |
| Notify parts of system on event | Observer |
| Complex object construction | Builder |
🔍 Pattern Triggers
- “I need to add new behavior without changing existing code” → Strategy, Decorator
- “This class is doing too much” → Use patterns to decompose responsibility.
- “Users should be able to extend this feature” → Apply Template Method, Observer, or Plugin using Command.
