Express backend running
Chat API proxy ready
Hot reload on file changes

💾 Installation

Full Setup Guide

Step 1: Clone Repository

git clone https://github.com/YOUR_USERNAME/netviz3d.git
cd netviz3d

Step 2: Install Dependencies

npm install
# or
yarn install

📡 API Documentation

Chat API Endpoints

Initialize Session

POST /api/convai/init
Content-Type: application/json

{}

Response:
{"sessionId": "-1"}

Send Message

POST /api/convai/chat
Content-Type: application/json

{
  "userMessage": "What is HTTP?",
  "sessionId": "-1"
}

Response:
{
  "text": "HTTP (HyperText Transfer Protocol)...",
  "sessionId": "-1",
  "audio": null
}

End Session

POST /api/convai/end
Content-Type: application/json

{"sessionId": "-1"}

Response:
{"success": true}

Frontend Services

convaiService.js

import { 
  initializeSession,     // Start new chat
  sendMessage,          // Send user message
  endSession,           // End session
  getSessionId,         // Get current session
  clearSession          // Clear session
} from './services/convaiService'

// Example usage:
const sessionId = await initializeSession()
const response = await sendMessage("Hello!", sessionId)

🐛 Troubleshooting

Local Development

Port Already in Use

# Find and kill process using port 5173/3001
lsof -i :5173  # macOS/Linux
netstat -ano | findstr :5173  # Windows

# Kill process
kill -9 <PID>  # macOS/Linux
taskkill /PID <PID> /F  # Windows

Dependencies Issue

# Clear and reinstall
rm -rf node_modules package-lock.json
npm install

Build Fails

npm run build
# Check error message and fix source files

Deployment Issues

Backend Won't Start (Render)

Check /opt/render/project/src/package.json error
Verify rootDir: netviz3d in render.yaml
Check CONVAI_API_KEY environment variable

Frontend Build Fails (Vercel)

Run npm run build locally to test
Check VITE_API_BASE environment variable
Verify backend URL is correct

Chat Not Working

Open DevTools (F12) → Console
Check for CORS errors
Verify backend is running
Confirm VITE_API_BASE points to backend

See SETUP_GUIDE.md for more troubleshooting.
