Does Flask support some kind of life cycle methods?

Question

Sanic framework supports life cycle methods such as before_server_start, after_server_start, before_server_stop and after_server_stop.

Is there something similar in Flask like this ?

I know there is a before_request and after_request, but I'm looking for something before application is even started. I need to query a database to check if there is a certain entry in it. If there is, do some processing on that data and then run flask app.

You could look at an Application Factory pattern, which would allow you to perform processing before the app object is created.
