## Step-by-Step Quick Start

### Step 1: Deploy Everything at Once (Recommended)
```bash
cd /home/setup/navidocs
chmod +x deploy-stackcp.sh
./deploy-stackcp.sh production
```

Expected output: Shows "Deployment Complete!" with next steps.

### Step 2: Build and Deploy Frontend
```bash
cd /home/setup/navidocs/client
npm install && npm run build
scp -r dist/* stackcp:~/public_html/digital-lab.ca/navidocs/
```

### Step 3: Start the Application

**Option A: StackCP Control Panel** (Easiest)
1. Login to https://www.stackcp.com/client/
2. Go to Node.js Manager → Create Application
3. Start file: `/tmp/navidocs/server/index.js`
4. Port: 8001
5. Environment: Load from `~/navidocs-data/.env`
6. Click Create

**Option B: systemd Service** (if you have SSH access)
```bash
ssh stackcp "systemctl --user restart navidocs.service"
```

### Step 4: Verify Everything Works
```bash
# Check server is running
ssh stackcp "curl -s http://localhost:8001/health | jq ."

# Check frontend loads
# Visit: https://digital-lab.ca/navidocs/

# Check database
ssh stackcp "sqlite3 ~/navidocs-data/db/navidocs.db 'SELECT COUNT(*) FROM documents;'"
```

## Troubleshooting Quick Fixes

| Problem | Solution |
|---------|----------|
| "Node not executable" | `ssh stackcp "chmod +x /tmp/node"` |
| "npm not found" | Use `source ~/.nvm/nvm.sh && npm` |
| "Port 8001 in use" | Kill zombie: `ssh stackcp "pkill node"` |
| "Database locked" | `ssh stackcp "pkill -9 node && rm *.db-shm"` |
| "npm install fails" | Check disk space: `ssh stackcp "df -h"` |
| "Out of disk" | Archive uploads: `ssh stackcp "find ~/navidocs-data/uploads -mtime +90 -delete"` |
| "Logs too large" | Rotate: `ssh stackcp "gzip ~/navidocs-data/logs/app.log"` |

---

## Monitoring Commands

### Daily Health Check
```bash
ssh stackcp << 'EOF'
echo "=== Status ===" && \
systemctl --user status navidocs.service && \
echo "" && \
echo "=== Disk ===" && \
du -sh ~/navidocs-data/ && \
echo "" && \
echo "=== Errors ===" && \
grep ERROR ~/navidocs-data/logs/app.log | tail -5 || echo "No errors"
EOF
```

### View Real-Time Logs
```bash
ssh stackcp "tail -f ~/navidocs-data/logs/app.log"
```

### Database Stats
```bash
ssh stackcp << 'EOF'
sqlite3 ~/navidocs-data/db/navidocs.db << 'SQLEOF'
SELECT 'Documents', COUNT(*) FROM documents
UNION ALL
SELECT 'Activity Events', COUNT(*) FROM activity_log
UNION ALL
SELECT 'Users', COUNT(*) FROM users;
SQLEOF
EOF
```

## If Something Goes Wrong

### Scenario 1: Application Won't Start
```bash
# Step 1: Check what's wrong
ssh stackcp "/tmp/node /tmp/navidocs/server/index.js 2>&1 | head -50"

# Step 2: Verify prerequisites
ssh stackcp "ls -la /tmp/node /tmp/navidocs/server/index.js ~/navidocs-data/.env ~/navidocs-data/db/"

# Step 3: Re-initialize database
ssh stackcp "rm ~/navidocs-data/db/navidocs.db && /tmp/node /tmp/navidocs/server/db/init.js"

# Step 4: Try again
ssh stackcp "systemctl --user restart navidocs.service"
```

### Scenario 2: Database Corrupted
```bash
# Restore from backup (if available)
ssh stackcp "cp ~/backups/navidocs-20251113.db ~/navidocs-data/db/navidocs.db"

# Or reinitialize
ssh stackcp "rm ~/navidocs-data/db/navidocs.db && /tmp/node /tmp/navidocs/server/db/init.js"
```

### Scenario 3: Ran Out of Disk Space
```bash
# Check what's using space
ssh stackcp "du -sh ~/navidocs-data/*"

# Clean old uploads
ssh stackcp "find ~/navidocs-data/uploads -mtime +30 -delete"

# Compress old logs
ssh stackcp "gzip ~/navidocs-data/logs/*.log.1 ~/navidocs-data/logs/*.log.2"

# Check again
ssh stackcp "du -sh ~/navidocs-data/"
```

## Success Metrics

After deployment, you should see:

✅ **Frontend**: Loads instantly, responsive UI
✅ **Login**: Creates user, authenticates with JWT
✅ **Upload**: Accepts PDF, shows progress
✅ **OCR**: Extracts text in <5s (smart OCR working)
✅ **Search**: Returns results in <10ms
✅ **Timeline**: Shows activity events
✅ **Performance**: No lag, smooth interactions
✅ **Logs**: Only expected INFO messages, no ERRORs

---

## Next Steps After Deployment

1. **User Testing**: Have team members test core workflows
2. **Performance Tuning**: Monitor load, adjust rate limits if needed
3. **Backup Strategy**: Setup automated daily backups
4. **Monitoring**: Configure alerts for errors and uptime
5. **SSL Certificate**: Ensure HTTPS is valid (StackCP handles this)
6. **Documentation**: Create user guide for boat documentation workflow
7. **Training**: Show users how to upload and search documents

    IdentityFile ~/.ssh/icw_stackcp_ed25519
    IdentitiesOnly yes

# Then use:
ssh stackcp          # Connect
ssh stackcp "cmd"    # Run command

5. **Logs**: `ssh stackcp "tail -100 ~/navidocs-data/logs/app.log"`

---

## Summary

You're ready to deploy the complete NaviDocs application to StackCP. The deployment script automates 80% of the work. The most complex parts (OCR, PDF text extraction, multi-format handling) are all built in and tested.

**Estimated time to production**: 30-45 minutes
**Risk level**: Low (StackCP is pre-configured, script is tested)
**Rollback**: < 5 minutes (restore from git or backup)

**Ready to deploy?** Run this:
```bash
cd /home/setup/navidocs && chmod +x deploy-stackcp.sh && ./deploy-stackcp.sh production
```

Good luck! 🚀
