How to Add a Prefix to All Routes in a Flask Application?

Prefixed Routes in Flask

When working with Flask routes, it may be desirable to add a common prefix to all routes. Instead of manually adding the prefix to each route definition, there is a more efficient way to automate this process.

Using Blueprints

Flask provides a concept called blueprints, which allow you to group related routes and define shared settings. To add a prefix to all routes in a flask application, you can create a blueprint:

Once the blueprint is defined, you can register it with the Flask application, specifying the desired prefix:

Now, all routes defined within the blueprint will automatically have the prefix '/abc/123' applied. This eliminates the need for manually adding the prefix to each route definition, making your code more concise and maintainable.
