• Support for PostgreSQL database and ORM models using SQLAlchemy. Example model.
• Support for migrations with alembic. Example migration.
• Support for background tasks with dramatiq. Example task.
• Configuration for running on Heroku cloud.
• Separate production, testing and development requirements.
• Easy testing with tox and py.test. Example tests.
• Support for fast and efficient testing of database code using transactions and parallel workers.
• Basic code linting with black, flake8 and isort.
• Github Actions testing with Python application setup.
• Easy entry vector for WSGI servers, demonstrated with Gunicorn.
• Dockerfile to build a minimal¸ production-ready Docker image.
• Rudimentary definition for Docker Compose to launch the complete project.

Note: Ensure you have a working system Docker installation.

Install Docker Compose:

$ pip install -U docker-compose

Start the complete stack in a standard way:

$ docker-compose up --build --detach

Check the logs

$ docker-compose logs --follow

Note: Ensure you have a working Python 3.8 installation.

Create a virtualenv:

$ virtualenv -p `which python3.8` .env

Install dependencies:

$ source .env/bin/activate
$ pip install -Ur requirements.txt

Prepare the environment (direnv has to be preinstalled):

$ cp envrc.example .envrc
$ direnv edit

Run the development web server:

$ flask run

Install the tooling:

$ pip install -U tox

Run the tests

$ tox
