This is one more in the series of mini-projects I have putting up on GitHub. This one uses Flask-restfull for the backend and Angular-CLI 9 for the frontend. After building the frontend, I compiled the package using

ng build

and moving the resulting built package in to 'static' directory of Flask package. Before running the app first the database has to be initialised with the following commands:

flask db init
flask db migrate
flask db upgrade

After that the application can be run using

flask run

Good luck!
