## 🚀 Deployment Steps

### Step 1: Commit All Changes

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

### Step 2: Deploy to Production

```bash
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:

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

### Step 4: Clear All Caches

```bash
# 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

```bash
# 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
```

## 🎯 Quick Deploy Command

```bash
# One command to deploy everything
ssh luckychit@192.168.8.148 "cd /home/luckychit/apps/chitfund && git pull origin prodnew && chmod +x scripts/*.sh && ./scripts/deploy.sh"
```

Then clear browser cache and refresh!

## 📝 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)
4. **Check PM2 logs** for any warnings
5. **Monitor for a few minutes** to ensure stability

## 🆘 If Something Breaks

```bash
# Run diagnostics
./scripts/diagnose.sh

# Check logs
pm2 logs --lines 50

# Restart everything
pm2 restart all

# Still broken?
# See TROUBLESHOOTING.md
