What is the best structure for a Flask application?

A well-structured Flask application typically follows the Model-View-Template (MVT) pattern. You should organize your code into directories for templates, static files, and application logic.

Can you give me an example of a directory structure?

Sure! A common structure looks like this:

/my_flask_app
    /app
        /templates
        /static
        /models
        /views
        /forms
    /instance
    config.py
    run.py

This separates your application logic from configuration and instance files.

What about using blueprints?

Blueprints are a great way to organize your application into modules. You can create a blueprint for each major component, like authentication or blog posts, which helps keep your codebase manageable.

How do I set up a blueprint?

To set up a blueprint, you can create a new file, import Blueprint, and define your routes. Then, register the blueprint in your main application file.
