Wrapping app.wsgi_app instead of app means that app still points at your Flask application, not at the middleware, so you can continue to use and configure app directly. Extensions are packages that help you accomplish common tasks. For example, Flask-SQLAlchemy provides SQLAlchemy support that makes it simple and easy to use with Flask.

In this example there are two decorators, which associate the URLs / and /index to this function. This means that when a web browser requests either of these two URLs, Flask is going to invoke this function and pass its return value back to the browser as a response.

Flask - Full Stack Python
Flask is considered more Pythonic than the Django web framework because in common situations the equivalent Flask web application is more explicit. Flask is also easy to get started with as a beginner because there is little boilerplate code for getting a simple app up and running. For example, here is a valid "Hello, world!" web application with Flask:

October 18, 2022 -
Are there some good examples of real applications (not hello world todo/blog post or tutorials) of Flask applications, from where a new flask user could learn best practices from?
Flask doesn't force any design patterns or specific ways to do anything on me, and that leaves me wondering about what are the best ways to do something. How do I split up the routes file from all-routes-in-a-file.py to something more manageable, how do I validate input requests coming from a JS front-end, what are the best practices for doing thing X and Y, that I haven't even thought about yet.
Background information: I am writing a back-end api for a Vue frontend, there are no templates in the flask app, I am using JWT for authentication already. I think I don't need blueprints, because I don't have any templates to separate from the other things. I just don't want to bunch all my routes together in a huge file, like.. all the examples on the internet do.
I have found some open-source flask examples, but they seemed to be doing something weird, or.. were really outdated.
Or should I just write my back-end in Java and Spring, since that is used at work, and I can steal ideas and patterns from work projects? Wanted to use flask, to not have to deal with the massiveness of Spring and Java.

I think I don't need blueprints, because I don't have any templates to separate from the other things. I just don't want to bunch all my routes together in a huge file, like.. all the examples on the internet do. Modularizing routes so they're not in one monolithic file is exactly the purpose of blueprints, so I would suggest revisiting them.

For big projects you should follow these principles: https://hackersandslackers.com/your-first-flask-application There are 11 parts, each one explains how to structure and build the different things like logins, connection to a database, structuring everything with blueprints etc. I found it very helpful to make the jump from the usual single-file-apps to having a good structure where you split the project into meaningful and easy manageable parts. edit: Just read, that you don't need blueprints, so you might jump over that part, but i think it's good to learn it anyway in case you want to extend your project later on.
