Custom Url Routing System

Fallback Routes:Fallback or catch-all routes handle requests that do not match any specific route. This is useful for implementing custom error pages or handling undefined routes gracefully.

Route Parameters Validation: Some routing systems provide mechanisms for validating route parameters, ensuring that they meet certain criteria (e.g., numeric, alphanumeric) before being processed.

RESTful Routing:For applications following RESTful principles, a custom URL routing system facilitates the definition of routes that correspond to different CRUD (Create, Read, Update, Delete) operations on resources.

Route Groups: Route groups allow developers to organize routes with a common prefix or set of middleware. This helps in structuring the application's routing in a modular and maintainable way.

Named Routes: Routes can be assigned names, making it easier to generate URLs dynamically in the application code. This is particularly useful for creating links to specific routes.

Route Middleware: Middleware functions can be applied to routes. Middleware runs before or after the main route handler and is useful for tasks such as authentication, logging, and modifying the request or response.

Parameterized URLs: URL routing systems often support parameterized URLs, where certain parts of the URL act as variables or placeholders. These parameters can be extracted and used as input for the associated function or controller.

HTTP Methods: URLs can be associated with specific HTTP methods (e.g., GET, POST, PUT, DELETE). This allows developers to define different actions for the same URL based on the HTTP method used in the reques

Route Definitions: Routes define the relationship between URL patterns and the corresponding functions or controllers in the application. Each route typically includes a URL pattern and a reference to the function or controller that should handle requests matching that pattern.

URL Patterns: Developers define URL patterns to specify the structure of URLs that their application can handle. These patterns often include placeholders for dynamic parts of the URL, such as parameters

HTTP Method Handling: 

• Definition: Routes can be associated with specific HTTP methods (GET, POST, PUT, DELETE) to handle different types of requests.
• Example: @app.route('/users', methods=['GET', 'POST'])

Route Parameter Validation: 

• Definition: Some routing systems provide mechanisms for validating route parameters, ensuring they meet specific criteria.
• Example: @app.route('/user/') validates that user_id is an integer.

Route Execution:  Routes can be composed or nested, allowing for modular and reusable route definitions.

Route Prefixing: Definition: Routes can be prefixed with a common path, simplifying the organization of routes.

• Example: @app.prefix('/blog', routes=[post_routes, comment_routes])
