Fastapi Local Dev

A practical runbook that cuts through FastAPI deployment confusion with the commands you actually need. It covers the essentials: Uvicorn with reload for development, the WSL polling workaround that saves you from headaches when file watching breaks, and the proper Gunicorn setup for production with UvicornWorker. The anti-patterns section alone is worth it, steering you away from combining reload with multiple workers or using PM2's watch mode for Python apps. It's the kind of reference you keep handy because you'll forget these flags between projects, and Googling them always pulls up outdated Stack Overflow threads. Nothing groundbreaking, just solid ops knowledge in a quick reference format.
