## Description
A project starter for personal usage containing the following:
- [Python 3.12.\*](https://www.python.org/)
- [FastAPI](https://fastapi.tiangolo.com/) web framework
- Structured logging using [`structlog`](https://www.structlog.org/)
- Dependency management using [`poetry`](https://python-poetry.org/)
- Containerisation using a Dockerfile
- Testing with [`pytest`](https://docs.pytest.org/) and optionally with coverage
with [`pytest-cov`](https://pytest-cov.readthedocs.io/)
- Linting/formatting using [`ruff`](https://beta.ruff.rs/docs/)
- [`.gitignore`](https://github.com/github/gitignore/blob/main/Python.gitignore)
## Prerequisites
- [Python 3.12.\*](https://www.python.org/downloads/)
- [Poetry](https://python-poetry.org/)
### 1. Install Python 3 and Poetry
**MacOS (using `brew`)**
```bash
brew install python3 poetry
```
**Ubuntu/Debian**
```bash
sudo apt install python3 python3-venv pipx
pipx ensurepath
pipx install poetry
```
### 2. Create a virtual environment with all necessary dependencies
From the root of the project execute:
```bash
poetry install
```
### 3. Activate your virtual environment
From the root of the project execute:
```bash
poetry shell
```
## Run application
Runs the FastAPI web application on port `8000` using [uvicorn](https://www.uvicorn.org/):
```bash
uvicorn fastapi_poetry_starter.main:app --reload
```
## Testing
```bash
pytest
```
### With coverage
```bash
pytest --cov=app
```
### With coverage and HTML output
```bash
pytest --cov-report html --cov=app
```
## Linting
```bash
ruff check fastapi_poetry_starter/* tests/*
```
## Formatting
```bash
ruff format fastapi_poetry_starter/* tests/*
```
## Containerisation
The following `podman` commands are direct replacements of the Docker CLI. You can see that their syntax is identical:
### 1. Build image and tag it as `fastapi-poetry-starter`
```bash
podman image build -t fastapi-poetry-starter .
```
### 2. Run a container of the previously tagged image (`fastapi-poetry-starter`)
Run our FastAPI application and map our local port `8000` to `80` on the running container:
```bash
podman container run -d --name fastapi-poetry-starter -p 8000:80 --network bridge fastapi-poetry-starter
```
### 3. Check running containers
```bash
podman ps
```
```bash
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
78586e5b4683 localhost/fastapi-poetry-starter:latest uvicorn main:app ... 13 minutes ago Up 5 minutes ago 0.0.0.0:8000->80/tcp nifty_roentgen
```
### 4. Hit sample endpoint
Our FastAPI server now runs on port `8000` on our local machine. We can test it with:
```bash
curl -i http://localhost:8000/healthcheck
```
Output:
```bash
HTTP/1.1 200 OK
server: uvicorn
content-length: 0
```
