Local development

git clone https://github.com/tzelleke/fastapi-sqlalchemy
cd fastapi-sqlalchemy
cp .env-example .env

docker-compose up [-d]
# -> visit localhost:8080

Dependency management

Python package dependencies are managed with Poetry.

Database

The project uses a SQLite database. That is, no DB server is involved. The database DSN is provided via the environment variable DATABASE_URL (see docker-compose.yml).

The default value, provided in docker-compose.yml, is sqlite:////app/db.sqlite. If you run alembic upgrade head for the first time it will create /app/db.sqlite in the container. Since the project folder is mapped to /app in the container this will create db.sqlite in the project folder.

Migrations

Database schema migrations are managed with Alembic.

# reset database
docker-compose [run | exec] app alembic downgrade base
docker-compose [run | exec] app alembic upgrade head

Seeding

docker-compose [run | exec] app inv seed

Housekeeping tasks

pyinvoke is used to run project-related tasks.

Project documentation

Project documentation is build with mkdocs-material.

./github/workflows/ci.yml defines a workflow to build the documentation on GitHub and publish to GitHub Pages.

You can work on the docs alongside local development.

# start local docs site
docker-compose up [-d] docs

The local docs service (see docker-compose.yml) is build from Dockerfile.mkdocs which installs additional mkdocs extensions into the base image.
!You have to add these extensions to the GitHub Actions workflow as well.
