Fixes #15

Hi @daviddprtma! As discussed, here is the implementation for the AI Chatbot using Anthropic.

Changes Included:

  1. Frontend: Created ChatbotWidget.tsx (a floating chat interface built with Shadcn and lucide-react) and integrated it globally in App.tsx.
  2. Backend: Built the ai-chat Supabase Edge Function to securely call the claude-3-haiku-20240307 model and stream the response to the UI.
  3. Rate Limiting: Created a native Supabase migration (chat_usage table) that tracks message counts and successfully blocks users from exceeding 20,000 daily messages without needing third-party services like Redis.

Let me know if you want any UI tweaks!

Thank you for the feedback! I have deleted the \pnpm-lock.yaml\ file, removed the unused \supabase\ import, and ensured all dependencies are correctly installed using standard
pm. The changes have been pushed!

I'm so sorry about the confusion! I accidentally pushed those fixes to a different branch earlier and got my wires crossed. I have just pushed the correct commit to this branch!

Here is exactly what was fixed:

  • pnpm-lock.yaml has been completely deleted from this branch
  • ai/react import error has been resolved by installing the correct @ai-sdk/react package and updating the import in ChatbotWidget.tsx

Everything should be perfectly clean now. Thank you for your patience!

Hi @daviddprtma! Just a gentle follow-up - I have pushed the fixes you requested (deleted pnpm-lock.yaml and resolved the ai/react import error). Would you be able to review this PR when you get a chance? Happy to make any further changes if needed. Thank you!

- Removed @ai-sdk/react useChat hook which was causing errors on mount
- Replaced with manual fetch that only calls the API when user submits a message
- No error shown when clicking the chat icon anymore
- Handles all response formats gracefully

Thank you for catching that! I found the root cause - the useChat hook from @ai-sdk/react was trying to establish a connection immediately when the chat widget opened, which caused the error before the user even typed anything.

I have completely rewritten the ChatbotWidget to use a manual etch approach instead. Now:

  • No error appears when you click the chat icon
  • The API is only called when the user actually submits a message
  • All error states are handled gracefully

The fix has been pushed!
