Register new module as a REST API in python flask dynamically

Creating a REST API in Python using Flask is a common task, and often you'll want to register new modules dynamically to add more routes and functionalities. In this tutorial, I'll walk you through the process of registering a new module as a REST API dynamically in Python-Flask, complete with code examples.
Before you begin, make sure you have the following:
To keep your project organized, you can use the following structure:
Now, let's create the app.py file to set up your Flask application:
This code initializes a Flask app. We'll now create modules that can be registered dynamically.
Inside the modules/ directory, create a new Python file, e.g., module1.py. This module will define a route that returns a simple message:
This code defines a Flask Blueprint for 'module1' and registers a single route.
Now, let's modify the app.py to register modules dynamically. We'll use the glob module to locate module files in the modules/ directory.
This code dynamically registers all modules found in the modules/ directory. It imports each module and adds its Blueprint to the Flask app.
You can now run your Flask application using python app.py and access the API at http://localhost:5000/module1/hello.
The module1 route should return a JSON response: {"message": "Hello from Module 1"}.
To add more modules, create new Python files in the modules/ directory following the same structure as module1.py. You can also define more routes in each module.
By following this approach, you can easily expand your REST API by just adding new modules to the modules/ directory without modifying the main application code.
That's it! You've created a Flask REST API and learned how to dynamically register modules to extend its functionality.
