Architecture

This project uses C4 model annotations embedded in the source code to generate architecture diagrams.

Viewing Diagrams

Diagrams are automatically generated in CI and uploaded as artifacts.

To generate locally:

# Install c4-literate-python
pip install git+https://github.com/ChristosDev75/c4-literate-python.git

# Generate diagrams
c4-literate tangle . -o docs/architecture/workspace.dsl

# View with Structurizr Lite
docker run -it --rm -p 8080:8080 \
  -v $(pwd):/usr/local/structurizr:Z \
  docker.io/structurizr/lite

# Open http://localhost:8080

Modifying Architecture

Architecture is documented using C4 annotations in Python docstrings. See the c4-literate-python schema for annotation reference.

Example:

"""
@c4-container: API Application
@c4-technology: Python 3.12, FastAPI
@c4-description: REST API providing CRUD operations
