## Deployment Phases

### Phase 1: Infrastructure Preparation (1 hour)

- [ ] **Node.js Setup**
  ```bash
  # Verify Node.js 18+
  node -v  # Should show v18+
  ```

- [ ] **PostgreSQL Setup**
  ```bash
  # Create database
  createdb tekdek_command_center
  
  # Create user with password
  createuser -P tekdek
  
  # Grant permissions
  psql << EOF
  GRANT ALL PRIVILEGES ON DATABASE tekdek_command_center TO tekdek;
  EOF
  ```

- [ ] **Nginx Configuration**
  - [ ] Copy nginx config from DEPLOYMENT_STRATEGY.md
  - [ ] Update server_name to actual domain
  - [ ] Verify syntax: `nginx -t`
  - [ ] Test reload: `systemctl reload nginx`

- [ ] **SSL Certificates**
  ```bash
  # Let's Encrypt for HTTPS
  certbot certonly --nginx -d command-center.tekdek.dev
  certbot certonly --nginx -d api.tekdek.dev
  ```

- [ ] **Create Deployment Directory**
  ```bash
  mkdir -p /opt/tekdek-command-center
  mkdir -p /var/www/tekdek-command-center
  mkdir -p /var/log/tekdek-command-center
  ```

### Phase 2: Backend Deployment (30 minutes)

  ```bash
  cd /opt/tekdek-command-center
  # Copy or git clone the command-center directory
  ```

- [ ] **Install Dependencies**
  ```bash
  npm install
  # Should complete with 0 vulnerabilities
  ```

- [ ] **Configure Environment**
  ```bash
  cp .env.example .env
  # Edit .env with actual credentials
  nano .env
  ```

  **Required Values**:
  - [ ] DATABASE_URL (PostgreSQL connection string)
  - [ ] PORT (typically 3000)
  - [ ] NODE_ENV=production
  - [ ] CORS_ORIGIN (frontend domain)
  - [ ] LOG_LEVEL=info

- [ ] **Initialize Database**
  ```bash
  npm run db:setup   # Create tables and indexes
  npm run db:seed    # Add initial users
  ```

  **Verify**:
  ```bash
  psql -U tekdek -d tekdek_command_center -c "SELECT COUNT(*) FROM users;"
  # Should show: 2
  ```

- [ ] **Test API Locally**
  ```bash
  npm start
  # Should show: "Server running on port 3000"
  ```

  **In another terminal**:
  ```bash
  curl http://localhost:3000/health
  # Should return: {"status":"ok","db":"connected",...}
  ```
