     Running flask app.run(debug=True) will make the Flask server watching
     the filesystem for source code changes and re-deploy your app.

   ==》 Hi,
   Thanks. I was aware of running it in debug mode, but I was looking for
   domething to use in production. I checked how werkzeug does it, see line
   160: https://github.com/pallets/werkzeug/blob/master/src/werkzeug/_reloader.py
   I'll study this in more detail tomorrow.
   Best wishes,
   Albert-Jan
