🔹 Unlock the Power of Behavioral Patterns in Ruby on Rails! 💡
Ever felt your Rails app getting messy, hard to scale, or difficult to maintain? 😵‍💫 Behavioral Design Patterns are your secret weapon to writing clean, efficient, and reusable code. 💎🚀 In this quick 60-second guide, let’s dive into some game-changing patterns every Rails developer should know! 🎯

🔹 1. Strategy Pattern 🎯
Use Case: Need to switch between multiple behaviors dynamically?
Example: Handling different payment methods (Stripe, PayPal, Razorpay).
🔑 Hack: Encapsulate algorithms into separate classes and switch at runtime.
🔹 2. Observer Pattern 👀
Use Case: Need to automatically update dependent objects when something changes?
Example: Notify users when a new blog post is published.
🔑 Hack: Use ActiveSupport::Notifications or Rails callbacks to trigger updates.
🔹 3. Command Pattern 🎮
Use Case: Want to encapsulate actions into objects for logging, undo/redo, or queueing?
Example: Background jobs in Sidekiq for sending emails, processing orders, etc.
🔑 Hack: Use Service Objects to structure command-like behavior.
🔹 4. Template Method Pattern 📜
Use Case: Need to define a general algorithm with customizable steps?
Example: Different types of reports (CSV, PDF, JSON) that share a common generation flow.
🔑 Hack: Use abstract parent classes with predefined steps and let child classes override specifics.
🔹 5. State Pattern 🔄
Use Case: Object behavior depends on different states?
Example: Order processing (Pending ➡️ Shipped ➡️ Delivered).
🔑 Hack: Use State Machines (AASM, StateMachine gem) to handle transitions effectively.
🔹 6. Chain of Responsibility Pattern 🔗
Use Case: Need to process requests in a sequential manner with flexibility?
Example: Middleware in Rails request handling (authentication, logging, rate limiting).
🔑 Hack: Implement a pipeline-like structure where each handler passes the request along.
🔹 7. Mediator Pattern 📢
Use Case: Need a centralized coordinator for complex interactions?
Example: Chat applications managing user messages via a central hub.
🔑 Hack: Use ActionCable in Rails to manage real-time interactions effectively.
🚀 Final Thought: Mastering Behavioral Patterns = Smarter Coding! 💎
