✅ Add unit tests and integration tests for backend and frontend
✅ Implement static code analysis:
- flake8 or pylint for Python
- eslint for Node.js
✅ Use multi-stage Docker builds to reduce the size of images
✅ Set up deployment to a server or cloud (e.g. Render, Railway, Kubernetes, AWS)
✅ Add HTTPS and automatic SSL certificates using Let's Encrypt (https://letsencrypt.org/)
✅ Store secrets and configurations via .env files, GitHub Secrets, Docker Compose env_file
✅ Add Healthchecks to docker-compose for backend and frontend to make sure that services are fully operational before nginx is launched
✅ Use a production-ready WSGI server, such as Gunicorn, instead of the built-in Flask server to improve performance and stability
