Repetition in code for routes in Flask (or Bottle)

Defining routes in Flask (or Bottle) involves creating multiple functions with the same pattern. To avoid repetition, we can use a decorator to define routes dynamically. Here are the steps to achieve this:

  1. Import the required modules: Begin by importing the necessary modules for Flask (or Bottle) and any other dependencies you may need.

  2. Create the Flask (or Bottle) app object: Instantiate the Flask (or Bottle) app object to create the web application.

  3. Define the route decorator: Create a custom route decorator function that takes the URL pattern as an argument. This decorator will be used to define routes dynamically.

  4. Create a list to store the routes: Initialize an empty list to store the route functions.

  5. Define the route decorator implementation: Implement the route decorator function by defining an inner function that takes the route function as an argument. Inside the inner function, register the route function with the Flask (or Bottle) app object using the URL pattern provided.

  6. Append the route function to the list: After registering the route function, append it to the list of routes.

  7. Register the routes dynamically: Use a loop or any other method to iterate over the list of route functions and call the route decorator on each function, passing the respective URL pattern.

  8. Run the Flask (or Bottle) app: Finally, run the Flask (or Bottle) app using the method to start the web application.

By following these steps, you can avoid repetition in code by defining routes dynamically using a decorator.
