March 5, 2024How do I write a Flask config file?
This doesn’t answer your question directly, but when I was learning flask I used this tutorial https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world and I can’t recommend it enough. The guy explains what he is doing and why it is needed. There is a part on Section 3 where he creates the config.py file which might be of some use? More on reddit.com

Guard your secret key with your life; ideally, even you shouldn't know the value of this variable.

Sometimes you’ll need to define configuration variables that contain sensitive information. We’ll want to separate these variables from those in config.py and keep them out of the repository. You may be hiding secrets like database passwords and API keys, or defining variables specific to a given machine. To make this easy, Flask gives us a feature called instance folders.

February 14, 2019 - Loading a config file is a simple one liner and should be placed as close to wherever you've created your app object. It's best practice to load the config as soon as possible, just after your app object is created so any other extension has access to your configuration variables.

Flask App Configuration: Best Practices and Techniques
January 26, 2024 - Advanced Flask configuration can be achieved through the use of class objects. This approach allows for the creation of distinct configuration sets for different environments, such as development, testing, and production. By defining these configurations as classes, developers can easily switch between them based on the current operational context.

r/flask on Reddit: What are the best practices and standard conventions for routes?
March 5, 2024 -
I've inherited the maintenance of a Flask app and there seems to be a lot of inconsistencies around the route syntax convention. In other words the project contains multiple instances of
@app.route(".....")
@app.get(".....")
@app.route("....." methods=[POST])
@app.post(".....") Etc. It's my understanding that
@app.get() == @app.route(methods=[GET]) == @app.route()
And
@app.post() == @app.route(methods=[POST])
Are there subtle differences I am missing, or are these functionally equivalent? Is one method considered standard convention/best practice over another?

In previous versions of flask, you had to do @app.route(methods=...). Nowadays you can do @app.post etc. They are functionally equivalent. But I recommend you go change all the @app.route to @app.post etc. if you can. The only time you cannot is if it is handling more than one method at once. In that case I would recommend breaking it out into two functions.

Like many things, it depends on your app design. app.get, app.post , app.patch, etc are all provided since flask 2 as handy shortcuts, but the original app.route usage is still in the core. For an API, I'd probably use the shortcuts as it improves readability. For a basic web application, I take into account that built in html forms only support get and post. I like to design routes that work for both get AND post. In that case, I use app.route and overload it with the additional methods. If i'm using something like htmx, then I may go with the shortcut methods to improve readability. Personally I'm set in my ways and just like using app.route for copy-paste-ability. But in essence app.get == app.route('/', methods=["GET"]) == app.route('/') since get is the default method and app.post == app.route('/', methods=["POST"]). What I DON'T like seeing is app.get and app.post all used, but then the one-off app.route used when you need mixed-method routes so I just prefer to use app.route. In the end, there aren't standard conventions governing the usage of these and their usage boils down to stylistic choice of the developer and the use cases of the app in question.
