Flask-web-app | Simple web app created using flask

I have followed this tutorial. It was working fine with until, in my __init__.py file, I import my recognizer file

Here is my project hierarchy:

Here is my HTML file :

I can't get flask run my css and js files. It just opens a page where all the images are missing and all the textfields and buttons etc. are all over the place. So I found out that the relevant files need to be in the static folder and the path has to be adjusted accordingly like at CSS Problems with Flask Web App or at External JavaScript file is not getting added when running on Flask. I implemented this. But it didn't really help. Apparently it's a common problem. I've tried a few other suggestions/solutions mostly focusing on the snytax and parentheses etc. here on stackoverflow but none helped. So my folder structure is this:

After running Flask for a few days as a live webserver, I learned this is not a smart thing to do: after some hours of inactivity the server died, even when I used the most simple setup (one page, no python code). Googling around I found out that Flask is not meant to be used as production server and a good practice is to combine it with e.g. Nginx and uWSGI. So I followed this guide and it seems to be running well. But now I have no clue how to restart, refresh or reload whatever it takes to publish te stuff I add to the content or to the python code. In stead of the Flask server, which reloads automatically after a file is saved (when in debug mode) I now have three engines running. Restarting nginx in terminal does not work, I've already tried that.

Please can somebody help this noob out?

TIA!!

============================

I am trying to write a simple API using Flask. I am following Miguel Grinberg's blog.

I have a use-case where I am trying to serve a static page. I am unable to serve the static webpage.

Here is my app.py

I installed Flask on Python 2.7.12/Apache 2.4/Ubuntu 16.04.1 LTS. I've been using these two tutorials to get set up. I'm not running venv or any other virtual environment (unlike this post). Running a simple Flask app works fine (a la "hello world"). I have a flaskapp.wsgi and a flaskapp.py in the same directory (/var/www/html).
