Review Summary
Excellent work on building this full-stack chat application! Your solution is approved as it successfully implements all the required features, from user authentication and room management to real-time messaging with WebSockets. The code is well-structured and demonstrates a solid understanding of both frontend and backend development.
While not required for approval, here are a few suggestions for future improvement:
- Client-Side Validation: In
MessageForm.jsxandRoomsList.tsx, consider adding a check likeif (text.trim())before submitting forms. This prevents sending empty messages or creating rooms with empty names, improving the user experience. - Typo: There's a small typo in
frontend/src/components/MessageList.jsx. The functionnormilizeTimeshould benormalizeTime. - Redundancy: In
src/index.js, theif (room)check in the/room-updateendpoint is redundant and can be removed to make the code slightly cleaner.
These are minor points in an otherwise outstanding submission. Keep up the great work!

The form currently allows sending empty or whitespace-only messages. It's a good practice to add a check here to ensure the text has content before calling sendMessage. For example, you could check if (text.trim()).

There's a small typo in the function name. It should be normalizeTime instead of normilizeTime. Correct spelling improves code readability.

It's good practice to prevent the user from submitting a form with an empty room name. While the server has validation, adding a client-side check here (e.g., if (!createRoomName.trim()) return;) would provide faster feedback and avoid an unnecessary API call.

This if (room) check is redundant. The code on lines 73-74 already handles the case where room is not found by returning early. If the execution reaches this line, room is guaranteed to exist, so you can safely remove this conditional check and just leave the assignment room.name = name;.
