🌟 CORE FEATURES:

• Registration and login using JWT Tokens

• Saving workout plans

• Saving current progress

• Follow other users

🧩 Design Patterns used in the project:

🎨 Decorator Pattern

Purpose:
Enhance or modify the behavior of functions or methods without altering their core functionality.

Examples in Project:

• Authentication and Authorization Decorators:
  Used in API routes to ensure only authenticated users access certain endpoints.
  Example: Checking for valid tokens before allowing access to user profile updates.
• Logging Decorators:
  Applied to log activities like login attempts and user actions.
  Example: Logging successful or failed login attempts, and user data access or updates.

📐 Model-View-Controller (MVC)

Purpose:
Separate application logic into three interconnected components: models, views, and controllers.

Examples in Project:

• Models (models.py):
  Define data structures such as UserModel and WorkoutModel, representing the application's data layer.
• Views (utils.py):
  Functions like get_all_user_plans prepare and present data, acting as the view layer in the application.
• Controllers (routes.py):
  Handle the incoming requests, process them using models, and return the appropriate views. Examples include endpoints for user authentication, data retrieval, and updates.

🔗 Singleton Pattern

Purpose:
Ensure a class has only a single instance, providing a global point of access to it.

Examples in Project:

• Database Connection Pool:
  Manages a single database connection pool for efficient database access across the application.

🏭 Factory Pattern

Purpose:
Create objects without specifying the exact class of the object that will be created.

Examples in Project:

• Workout Plan Creation ('factories.py'):
  Factory to create new sets of exercises.
• User Creation ('factories.py'):
  Factory to create new user in system.
• Plan Creation ('factories.py'):
  Factory to create new plan in system.
