Review Summary
Thank you for your hard work! Before this Pull Request can be approved, there are a few critical issues that need to be addressed to ensure your application works reliably:
-
Form Submission Handlers:
- In both
App.jsx(handleMessageSend) andLogin.jsx(handleNameSubmit), the form submission handlers do not callevent.preventDefault(). This can cause the page to reload unexpectedly when submitting forms, disrupting the user experience. Please update both handlers to accept theeventparameter and callevent.preventDefault()at the start of each function.
- In both
-
WebSocket Error Handling:
- In your server's
index.js, throwing an error inside the async WebSocket message handler (ws.on('message')) can crash the server because it is not caught by any outer try/catch. Instead, you should log the error usingconsole.errorand optionally send an error message to the client usingws.send. This will make your server more robust and prevent unexpected crashes.
- In your server's
Once you address these issues, your solution will meet all core requirements! 😊 Keep up the great work—you're almost there! If you need help with the fixes, feel free to ask or check the React forms documentation and Node.js error handling best practices.

Issue: The handleMessageSend function is used as the onSubmit handler for the form, but it does not call event.preventDefault(). This can cause the page to reload when the form is submitted. Please update handleMessageSend to accept the event parameter and call event.preventDefault() at the start of the function.
