Review Summary

I am requesting changes because one explicit functional requirement from the checklist is not yet met, which makes this a blocking issue. The server is required to set both the HTTP status code and status text explicitly: 200 with status text "OK" for successful responses, and 400 with status text "Bad request" for validation errors ([CHECKLIST ITEM #9] and [CHECKLIST ITEM #16]). Currently, in src/createServer.js and src/validateRequest.js you only set the status code (e.g. res.statusCode = 400 or res.writeHead(200, { ... })) and omit the explicit status message, so the behavior relies on Node’s defaults instead of conforming to the requirement.

To fix this, update your responses to use the writeHead overload that includes the status message, for example:

• For errors (e.g. where validation fails in createServer or validateRequest): res.writeHead(400, 'Bad request', { 'Content-Type': 'application/json' });
• For success (where you return the conversion result): res.writeHead(200, 'OK', { 'Content-Type': 'application/json' });

Everything else—URL parsing, validation messages, JSON response shapes, and use of convertToCase/detectCase—is correctly implemented and aligned with the task. As a minor, non-blocking improvement, you can also remove or actually use the unused PORT parameter in createServer to keep the API clear. Once you explicitly set the status text in both success and error paths, your solution should fully satisfy the requirements. Keep up the good work; you’re very close to completion.

The PORT parameter is unused. While not breaking functionality, it’s misleading; either remove it or use it where the server is actually started so the function signature reflects its behavior.

[mateacademy-ai-mentor]

For error responses, the checklist requires status code 400 with status text Bad request. Here you only set statusCode; consider using res.writeHead(400, 'Bad request', { 'Content-Type': 'application/json' }) or setting res.statusMessage = 'Bad request' before ending the response.

[mateacademy-ai-mentor]

Successful responses must be 200 with status text OK according to the requirements. Here you’re only passing the status code; update this to include the status text (e.g. res.writeHead(200, 'OK', { 'Content-Type': 'application/json' })).

[mateacademy-ai-mentor]

The error response correctly sets status code 400 and JSON content type, and returns the required { errors: [...] } payload, but checklist items #15 and #16 also require the status text to be explicitly set to "Bad request". In Node you can satisfy this by using res.writeHead(400, 'Bad request', { 'Content-Type': 'application/json' }) instead of only setting statusCode.

[mateacademy-ai-mentor]

For successful responses checklist item #9 requires status 200 with status text "OK". Here you set only the status code and headers; consider using the writeHead overload that includes the status message, e.g. res.writeHead(200, 'OK', { 'Content-Type': 'application/json' }), to fully match the requirement.

Review Summary

I am approving your solution because it now fully matches the functional and technical requirements for the case-conversion server. Your createServer implementation correctly uses Node’s http module, delegates parsing to getRequestData, and calls validateRequest before invoking convertToCase, all in the expected control flow. Validation covers all required rules (missing text, missing toCase, unsupported case) and returns an array of errors, and the error responses use status 400 with status text "Bad request" and the correct JSON shape { "errors": [ { "message": ... } ] }. On the success path, you call convertToCase(originalText, targetCase) and include originalCase, targetCase, originalText, and convertedText in the 200 "OK" JSON response, always setting Content-Type: application/json. There are no remaining critical or blocking issues; any remaining differences would be purely stylistic and not required for this task. Nicely done bringing everything in line with the specification and supporting multiple validation errors cleanly.
