Flask is for me one of the best frameworks for web development applications in Python, is well used abroad and is very flexible, leaving to the developers the role of building the project the way they want.
See the documentation.
The boilerplate for a starting project might be like the below, create a file called app.py (it does not need to be this name, it can be any name, unless Flask.py):
from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello_world():
return "<p>Hello, World!</p>"
Then run like the following, the parameter -- app app points to the starter file, for our case is app.py without the .py and run is the command. Other commands might be added also and used in the same form.
flask --app app run
Because Flask is very flexible, there is no specific way of structuring the project, it will depend on someone’s feelings and wishes, my way of doing it is described below.
Create the app.py starter file
…
Use Blueprints for contained modules … Add a configuration file for the main stuff happening on Flask…
Create an infra folder for all abstractions on infrastructure
…
Use commands for the usual actions on the flask … Improvement is my middle name, so this list might change a lot, and it will be noticed on my GitHub projects.
There is a Python package called preview that encapsulates a “webview” into standalone windows running behind GUI engines such as PyQT. The applications are many, but for our case, we can pass the starter flask object to it and it will render for us, like below:
import webview
from flask import Flask
app = Flask(__name__)
# Pretend the rest of the flask application is here
webview.create_window('Flask Application', app)
webview.start()
The webview.start() is the entrypoint of the application now, so instead of using Flask run you need only to run the python file as usual like below:
python app.py
TODO: Create an example with commands in flask.
I created a list of Q&A sections with all the things I found out about this tool.
