backend-server-startup

To safely start a FastAPI backend, this skill validates port availability and project context before launching Uvicorn. It provides a guided startup sequence that checks environment readiness, preventing common port conflicts and misconfigurations during development.

FastAPI backend startup connections often fail due to missing or incorrect CORS middleware. This skill performs safety checks to ensure CORS is present and correctly configured, allowing frontend access and preventing connection errors during development.

Before launching a FastAPI development server, you need to verify port status, base_path configuration, and environment readiness. This skill automates these prerequisite validations to ensure the project context is correctly set up for a successful startup.

To verify a FastAPI server is reachable after starting Uvicorn, perform post-startup checks against the expected API endpoint. This skill includes automated verification steps that confirm the service is available and responding successfully.

The best way to debug Uvicorn startup issues is using a guided startup sequence with automatic error detection. This skill enforces prerequisites, validates base_path configuration, and analyzes startup logs to prevent and resolve common environment issues.
