    • Get connection string
    • Whitelist all IPs (0.0.0.0/0) for serverless

  2. Deploy Backend to Vercel

    cd backend
npm install -g vercel
vercel
    • Set environment variables in Vercel dashboard
    • Add vercel.json in backend folder:
    {
  "version": 2,
  "builds": [{ "src": "server.js", "use": "@vercel/node" }],
  "routes": [{ "src": "/(.*)", "dest": "/server.js" }]
}

  3. Environment Variables (Vercel Dashboard):

    NODE_ENV=production
MONGO_URI=mongodb+srv://user:pass@cluster.mongodb.net/shophub
JWT_SECRET=your_production_secret
STRIPE_SECRET_KEY=sk_live_your_key
STRIPE_PUBLISHABLE_KEY=pk_live_your_key
CLOUDINARY_CLOUD_NAME=your_name
CLOUDINARY_API_KEY=your_key
CLOUDINARY_API_SECRET=your_secret
FRONTEND_URL=https://your-frontend.vercel.app

Frontend Deployment (Vercel)

  1. Deploy Frontend

    cd frontend
vercel
