How do you design consistent API error responses that the frontend can handle?
Answer
Consistent errors improve UX and reduce bugs.
**Design:**
- Use a stable error shape (code, message, details)
- Map validation errors per field
- Use HTTP status codes correctly
- Include correlation IDs for support
Avoid leaking sensitive server details. Frontend can then show helpful messages and retries reliably.
