✓ 应当这么做
- ✓ Validate every request body and query string at the handler boundary
- ✓ Centralise error handling in one middleware that maps typed errors to status codes
- ✓ Read configuration from the environment exactly once at startup
✕ 常见反模式
- ✕ Blocking the event loop with synchronous fs or CPU-heavy work
- ✕ Catch-all `next(err)` used to hide programming mistakes
- ✕ Answering requests before all awaited side effects complete
◎ 交付前验证
- ◎ Integration tests cover the success and the failure branch of each new route
- ◎ No unhandled promise rejection warnings in the test output
- ◎ Graceful shutdown drains in-flight requests
