Okay, I can help you set up the client-side structure for a secure WebSocket connection that interacts with a chatbot and plays piano notes using Tone.js based on the responses. This setup assumes you have a secure WebSocket server (`wss://...`) endpoint for your chatbot already running. You will need to replace the placeholder URL in the code with your actual endpoint. { "name": "websocket-chatbot-tonejs", "private": true, "version": "0.0.0", "type": "module", "scripts": { "dev": "vite", "build": "vite build", "preview": "vite preview" }, "devDependencies": { "vite": "^5.2.0" }, "dependencies": { "tone": "^15.0.4" } } WebSocket Chatbot with Tone.js

npm install && npm run dev **To use this:** 1. **Replace Placeholder:** Open `src/main.js` and change the `WSS_URL` constant to your actual secure WebSocket server address. 2. **Adjust Message Format:** Modify the `socket.onmessage` and `sendMessage` functions in `src/main.js` to match the exact JSON (or other) format your chatbot expects and sends. 3. **Run:** The `run.sh` script will install dependencies (`tone`, `vite`) and start the Vite development server. 4. **Start Audio:** Because browsers restrict audio playback until user interaction, you'll likely need to click the "Start Audio" button that appears before any sound can be played. 5. **Interact:** Type messages in the input field and press Enter or click Send. When the chatbot responds via the WebSocket, the message should appear, and a random piano note should play. This provides the client-side foundation. Remember that the security (`wss://`) depends entirely on the server you are connecting to having a valid SSL/TLS certificate.
