+# TekDek Command Center - Deployment Strategy
+
+**For**: Hephaestus, Operations Engineer  
+**Date**: 2026-04-13  
+**Status**: DEPLOYMENT ROADMAP READY
+
+---
+
+## Executive Summary
+
+The TekDek Command Center consists of two components:
+
+1. **Backend API** (Node.js + Express + PostgreSQL) - `src/` directory
+2. **Frontend UI** (Static HTML/CSS/JS) - `ui/` directory
+
+Both are production-ready and can be deployed independently. This document provides the complete deployment strategy for `web.tekdek.dev`.
+
+---
+
+## Component 1: Frontend UI
+
+### What It Is
+- Pure HTML/CSS/JavaScript (zero dependencies)
+- Responsive design (desktop, tablet, mobile)
+- Connects to backend API for data
+- ~57 KB total size (15 KB gzipped)
+
+### Files Needed
+```
+ui/index.html      (12.5 KB)
+ui/styles.css      (19.1 KB)
+ui/api.js          (5.8 KB)
+ui/ui.js           (19.0 KB)
+ui/app.js          (336 B)
+```
+
+### Deployment Options
+
+#### Option A: Nginx (Recommended for web.tekdek.dev)
+
+1. **SSH to web.tekdek.dev**
+   ```bash
+   ssh root@web.tekdek.dev
+   ```
+
+2. **Create deployment directory**
+   ```bash
+   mkdir -p /var/www/tekdek-command-center
+   cd /var/www/tekdek-command-center
+   ```
+
+3. **Copy UI files**
+   ```bash
+   # From local machine:
+   scp -r ui/* root@web.tekdek.dev:/var/www/tekdek-command-center/
+   ```
+
+4. **Configure Nginx**
+   ```nginx
+   # /etc/nginx/sites-available/command-center
+   server {
+       listen 80;
+       listen 443 ssl http2;
+       server_name command-center.tekdek.dev;
+
+       # Redirect HTTP to HTTPS
+       if ($scheme = http) {
+           return 301 https://$server_name$request_uri;
+       }
+
+       # SSL certificates (setup with Let's Encrypt)
+       ssl_certificate /etc/letsencrypt/live/command-center.tekdek.dev/fullchain.pem;
+       ssl_certificate_key /etc/letsencrypt/live/command-center.tekdek.dev/privkey.pem;
+
+       root /var/www/tekdek-command-center;
+
+       # SPA routing - serve index.html for all routes
+       location / {
+           try_files $uri $uri/ /index.html;
+       }
+
+       # Cache static assets for 1 year
+       location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2)$ {
+           expires 1y;
+           add_header Cache-Control "public, immutable";
+       }
+
+       # Enable gzip compression
+       gzip on;
+       gzip_types text/plain text/css application/javascript text/xml application/xml;
+       gzip_min_length 1000;
+   }
+   ```
+
+5. **Enable the site**
+   ```bash
+   sudo ln -s /etc/nginx/sites-available/command-center /etc/nginx/sites-enabled/
+   sudo nginx -t  # Test config
+   sudo systemctl restart nginx
+   ```
+
+6. **Setup SSL (Let's Encrypt)**
+   ```bash
+   sudo certbot certonly --nginx -d command-center.tekdek.dev
+   ```
+
+#### Option B: Alternative - Deploy to Web Root
+
+If deploying to existing web.tekdek.dev:
+
+```bash
+# Place UI files at: /var/www/web.tekdek.dev/command-center/
+# Access at: https://web.tekdek.dev/command-center/
+```
+
+### Configuration
+Edit `ui/api.js` to set backend URL:
+
+```javascript
+// Line 1 in api.js
+const BASE_URL = 'https://api.tekdek.dev/api/v1';  // Production
+// OR
+const BASE_URL = 'http://localhost:3000/api/v1';   // Development
+```
+

+# Verify installation
+node -v  # Should be v20+
+npm -v
+```
+
+#### 2. Setup PostgreSQL
+
+```bash
+# Install PostgreSQL
+apt install -y postgresql postgresql-contrib
+
+# Start service
+sudo systemctl start postgresql
+sudo systemctl enable postgresql
+
+# Create database
+sudo -u postgres psql << EOF
+CREATE DATABASE tekdek_command_center;
+CREATE USER tekdek WITH ENCRYPTED PASSWORD 'secure_password_here';
+GRANT ALL PRIVILEGES ON DATABASE tekdek_command_center TO tekdek;
+\c tekdek_command_center
+-- Grant schema permissions
+GRANT ALL ON SCHEMA public TO tekdek;
+EOF
+
+# Verify
+sudo -u postgres psql -l | grep tekdek_command_center
+```
+
+#### 3. Deploy Application
+
+```bash
+# Create app directory
+mkdir -p /opt/tekdek-command-center
+cd /opt/tekdek-command-center
+
+# Clone or copy code
+git clone <repo-url> .
+# OR copy files manually
+scp -r command-center/* root@api.tekdek.dev:/opt/tekdek-command-center/
+
+# Install dependencies
+npm install
+
+# Setup environment
+cp .env.example .env
+# Edit .env with actual values:
+nano .env
+```
+
+#### 4. Configure Environment
+
+**.env file:**
+```bash
+# Database
+DATABASE_URL=postgresql://tekdek:secure_password_here@localhost:5432/tekdek_command_center
+DATABASE_POOL_MIN=5
+DATABASE_POOL_MAX=20
+
+# Server
+PORT=3000
+NODE_ENV=production
+LOG_LEVEL=info
+
+# CORS
+CORS_ORIGIN=https://command-center.tekdek.dev
+
+# Logging
+LOG_FILE=/var/log/tekdek-command-center/api.log
+```
+
+#### 5. Initialize Database
+
+```bash
+# Create schema and seed data

+
+# Verify
+npm run db:check
+```
+
+#### 6. Start Application
+
+**Option A: Direct (Development)**
+```bash
+npm start
+# Server runs at http://localhost:3000
+```
+
+**Option B: With PM2 (Recommended for Production)**
+
+```bash
+# Install PM2 globally
+npm install -g pm2
+
+# Start app with PM2
+pm2 start src/index.js --name "tekdek-api" --env production
+
+# Auto-restart on reboot
+pm2 startup
+pm2 save
+
+# Monitor
+pm2 monit
+pm2 logs tekdek-api
+```
+
+**Option C: With Systemd (Alternative)**
+
+Create `/etc/systemd/system/tekdek-api.service`:
+```ini

+RestartSec=10
+Environment="NODE_ENV=production"
+Environment="DATABASE_URL=postgresql://..."
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Enable:
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable tekdek-api
+sudo systemctl start tekdek-api
+sudo systemctl status tekdek-api
+```
+
+#### 7. Configure Reverse Proxy (Nginx)
+
+```nginx
+# /etc/nginx/sites-available/api
+upstream tekdek_api {
+    server 127.0.0.1:3000;
+    keepalive 64;
+}
+
+server {
+    listen 80;
+    listen 443 ssl http2;
+    server_name api.tekdek.dev;
+
+    # Redirect HTTP to HTTPS
+    if ($scheme = http) {
+        return 301 https://$server_name$request_uri;
+    }
+
+    # SSL configuration
+    ssl_certificate /etc/letsencrypt/live/api.tekdek.dev/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/api.tekdek.dev/privkey.pem;
+
+    # Proxy to Node.js
+    location / {
+        proxy_pass http://tekdek_api;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_cache_bypass $http_upgrade;
+    }
+
+    # Health check
+    location /health {
+        access_log off;
+        proxy_pass http://tekdek_api;
+    }
+}
+```
+
+Enable:
+```bash
+sudo ln -s /etc/nginx/sites-available/api /etc/nginx/sites-enabled/
+sudo nginx -t
+sudo systemctl restart nginx
+```
+
+---
+
+## Deployment Verification
+
+### Frontend Health Check
+
+```bash
+# Test UI loads
+curl https://command-center.tekdek.dev
+
+# Should return HTML content with index.html
+
+# Test API URL is correct
+curl https://command-center.tekdek.dev/api.js | grep BASE_URL
+```
+
+### Backend Health Check
+
+```bash
+# Test API health endpoint
+curl https://api.tekdek.dev/health
+
+# Should return:
+# {
+#   "status": "ok",
+#   "db": "connected",
+#   "uptime_ms": 12345,
+#   "timestamp": "2026-04-13T15:42:00Z"
+# }
+```
+
+### Test All 10 Endpoints
+
+```bash
+# Create a project
+curl -X POST https://api.tekdek.dev/api/v1/projects \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "Test Project",
+    "description": "Testing deployment",
+    "color_hex": "#3498db"
+  }'
+
+# Should return 201 with project data
+```
+
+See `ui/TESTING.md` for complete test scenarios.
+
+---
+
+## Post-Deployment Tasks
+
+### 1. Setup Monitoring
+
+**Application Logs:**
+```bash
+# View logs
+tail -f /var/log/tekdek-command-center/api.log
+
+# Parse JSON logs
+tail -f /var/log/tekdek-command-center/api.log | jq .
+```
+
+**System Monitoring:**
+```bash
+# CPU/Memory
+top
+
+# Disk space
+df -h
+
+# Process status
+ps aux | grep node
+```
+
+### 2. Configure Backups
+
+**Database Backups (Daily):**
+```bash
+# /usr/local/bin/backup-tekdek-db.sh
+#!/bin/bash
+BACKUP_DIR="/backups/tekdek"
+mkdir -p $BACKUP_DIR
+pg_dump -U tekdek tekdek_command_center | \
+  gzip > $BACKUP_DIR/db-$(date +%Y%m%d-%H%M%S).sql.gz
+
+# Keep last 30 days
+find $BACKUP_DIR -mtime +30 -delete
+```
+
+Add to crontab:
+```bash
+crontab -e
+# 2 AM daily backup
+0 2 * * * /usr/local/bin/backup-tekdek-db.sh
+```
+
+### 3. Setup Error Alerting
+
+**Email on Errors:**
+```bash
+# /usr/local/bin/monitor-errors.sh
+LOG_FILE="/var/log/tekdek-command-center/api.log"
+tail -f $LOG_FILE | grep ERROR | mail -s "TekDek API Error" ops@tekdek.dev
+```
+
+### 4. Performance Monitoring
+
+**Lighthouse Audit:**
+```bash
+# From local machine
+lighthouse https://command-center.tekdek.dev --view
+```
+
+**API Performance:**
+```bash
+# Monitor response times
+curl -w "Time: %{time_total}s\n" \
+     https://api.tekdek.dev/api/v1/projects
+```
+
+---
+
+## Scaling Considerations
+
+### Phase 1 (Current - Up to 1000 tasks)
+- Single server
+- Local PostgreSQL
+- No caching
+- Single PM2 instance
+
+### Phase 2 (10,000+ tasks)
+- Add Redis cache layer
+- Read replicas for database
+- Load balancing with multiple API instances
+- CDN for static assets
+
+### Phase 3 (100,000+ tasks)
+- Separate database cluster
+- Horizontally scaled API servers
+- Message queue for async jobs
+- Dedicated monitoring infrastructure
+
+---
+
+## Troubleshooting
+
+### Backend Won't Start
+
+```bash
+# Check logs
+pm2 logs tekdek-api
+
+# Check port is available
+netstat -tln | grep 3000
+
+# Check database connection
+psql -U tekdek -d tekdek_command_center -c "SELECT 1;"
+```
+
+### Database Connection Error
+
+```bash
+# Verify credentials in .env
+cat /opt/tekdek-command-center/.env | grep DATABASE_URL
+
+# Test connection directly
+psql postgresql://tekdek:password@localhost:5432/tekdek_command_center
+```
+
+### CORS Errors in Frontend
+
+```bash
+# Check backend CORS header
+curl -H "Origin: https://command-center.tekdek.dev" \
+     https://api.tekdek.dev/api/v1/projects -v
+
+# Should have: Access-Control-Allow-Origin: https://command-center.tekdek.dev
+```
+
+### Slow API Responses
+
+```bash
+# Check database query times
+sudo -u postgres psql -d tekdek_command_center << EOF
+SELECT query, calls, total_time FROM pg_stat_statements
+ORDER BY total_time DESC LIMIT 10;
+EOF
+
+# Check indexes are created
+sudo -u postgres psql -d tekdek_command_center -c "\di+"
+```
+
