Review Summary

Your implementation fully satisfies all task requirements. Both src/createServer.js and src/validateRequest.js correctly implement the case transformer server with proper URL parsing using URLSearchParams, input validation with exact error message formats, and appropriate JSON response structures for success (200 OK) and error (400 Bad Request) cases. The code properly integrates the convertToCase business logic and handles all five case types (SNAKE, KEBAB, CAMEL, PASCAL, UPPER) as specified. All 19 checklist requirements pass, including proper export of createServer, correct URL parameter handling (/TEXT?toCase=CASE), validation for text and toCase parameters, and multiple error message support. No critical issues or blockers were found. Great work on implementing this cleanly and following the exact specifications!
