🚀 Deployment Steps

Step 1: Commit All Changes

git add .
git commit -m "Production fixes: APIs, UI cleanup, cache-busting, consolidation"
git push origin prodnew

Step 2: Deploy to Production

ssh luckychit@192.168.8.148
cd /home/luckychit/apps/chitfund
git pull origin prodnew

# Make scripts executable
chmod +x scripts/*.sh

# Deploy everything
./scripts/deploy.sh

Step 3: Fix bcrypt Error (If Needed)

If you see "invalid ELF header" error:

cd /home/luckychit/apps/chitfund/backend
rm -rf node_modules package-lock.json
npm install
pm2 restart luckychit-api

Step 4: Clear All Caches

# On server - already done by deploy script
pm2 restart all

# Clear nginx cache (if using separate proxy LXC)
ssh root@<nginx-proxy-ip>
sudo rm -rf /var/cache/nginx/*
sudo systemctl reload nginx

# In browser - Clear service worker
# F12 → Application → Service Workers → Unregister all
# Then: Ctrl + Shift + R (hard refresh)

Step 5: Verify Everything Works

# Check PM2 status
pm2 status

# Check logs for errors
pm2 logs --lines 30

# Test backend APIs
curl http://localhost:3000/health
curl -H "Authorization: Bearer TOKEN" http://localhost:3000/api/notifications

# Test frontend
curl http://localhost:8080

# Test from domain
curl https://chitfund.deepteklabs.com/health

📝 Post-Deployment

After successful deployment:

  1. Test in incognito first (no cache)
  2. Verify APIs work without errors
  3. Test user flows (signup, login, dashboard)
