ReadingFlask source code is a good thing. Before reading, I suggest you ask yourself the following questions:
Are you familiar with the main Flask of API? Do you know a Flask app complete workflow
Are you familiar with B/S this kind of framework, are you familiar with the relevant network protocols (HTTP,TCP), are you clear about the client sending a request, the server processing and responding to the request and its details
Are you familiar with the gateway interface protocol (Python web) developed by WSGI
If these are all clear, you can read Flask carefully before reading the werkzeug source code.
werkzeug is the foundation of the flask framework. Most of the above problems are implemented in the werkzeug library. FlaskIt is just a more advanced package and designed to be more suitable for developersAPI.
After you are familiar with werkzeug, and then look at Flask, you should not have any confusion about the configuration file.
PS: I am not a master, but I just finished reading the Flask source code recently.
When reading the flask source code, it is recommended to first read the code submitted by flask for the first time on github. It is just a flask.py file, but the basic concepts are already there.
