Integrating Flask with Clean Architecture
Having established our presentation patterns and state management approach, we now turn to the practical integration of Flask into our Clean Architecture system. Building on the application container structure seen earlier in Understanding interface flexibility in Clean Architecture, we’ll focus on the Flask-specific aspects of our web interface:
- Configuring Flask’s application factory pattern
- Managing Flask-specific settings and dependencies
- Connecting Flask routes to our core application logic
Here’s how our Flask application factory integrates with our existing architecture:
# todo_app/infrastructure/web/app.py
def create_web_app(app_container: Application) -> Flask:
"""Create and configure Flask application."""
flask_app = Flask(__name__)
# Change this in production:
flask_app.config["SECRET_KEY"] = "dev"
...
