Common Backend for Minerva

Collect all similar endpoints in the app/controller folder. Use different files for logically dissimilar endpoints.

NOTE: Most of the general config is loaded into the environment from the .env file which should be created from the provided .env.template

Setting up the project locally

Please use pipenv.

To install pipenv run pip install pipenv.

Use a separate virtual environment by running pipenv shell --three and then run pipenv install to install dependencies.

NOTE: Run pipenv install --dev to install all dependencies including development.

Adding new dependencies

To install a new dependency, use pipenv install <pkg-name>. This will update Pipfile and Pipfile.lock

NOTE: use the flag --dev if it is a development dependency.

To upgrade a package, use pipenv install --selective-upgrade <pkg-name>.

Whenever a new dependency is added, be sure to run

pip freeze > requirements.txt

Mention dependency change in the commit message.
