Do not use in production, ever. Seriously.
In order to run test application using pipenv:
pip install --user pipenv
- setup new pipenv environment in any IDE
or pip install 'pandas', 'flask', 'flask_restful' and 'requests' manually, then run server.py script.
Once server is running, use postman collection to perform tests. Report Bugs.
