Phase 1 UI Re-Architecture - Deployment Checklist

Date: 2025-12-09

Version: Phase 1 - Feature Module Architecture

---

✅ Completed Work

Phase 1: UI Re-Architecture

• Cycle 1: Architecture plan elaborated with Gemini 3 Pro
• Cycle 2: Implementation completed
  • Enhanced app-store.js with project management
  • Created ds-project-selector component
  • Updated router.js with 6 module routes
  • Restructured ds-shell.js navigation
  • Created 6 feature module placeholders
• Cycle 3: Expert code review conducted

Critical & Medium Fixes Applied

• CRITICAL: Fixed memory leak in ds-shell.js
  • Added disconnectedCallback() lifecycle method
  • Bound hashchange handler properly
  • Prevents event listener accumulation
• MEDIUM: Improved error handling in app-store.js
  • fetchProjects() now clears errors on success
  • getProjectConfig() sets error state for UI feedback
  • Better distinction between empty results and API errors
• MEDIUM: Fixed race condition in setupNavigationHighlight()
  • Wrapped DOM queries in requestAnimationFrame
  • Added element existence check
• COMPILATION: TypeScript compiles with 0 errors
• BUILD: Vite dev server runs successfully

---

📋 Pre-Deployment Checklist

Code Quality

• All critical issues resolved
• All medium priority issues resolved
• TypeScript compilation successful
• No console errors in development
• Low priority issues documented for future sprints

Testing

• Manual smoke test of navigation between modules
• Verify project selector functionality
• Test hash-based routing (back/forward buttons)
• Verify no memory leaks over time (Chrome DevTools Memory profiler)
• Test error states (disconnect network, verify error messages)

Documentation

• Code review findings documented
• Architecture changes documented
• Deployment checklist created
• Update CHANGELOG.md with Phase 1 completion
• Document known low-priority issues for backlog

---

🚀 Deployment Steps

1. Backend Server

cd /home/overbits/dss/server
npm run build  # If using TypeScript compilation
pm2 start server.js --name dss-server  # Or your process manager
pm2 save

2. Frontend Admin UI

cd /home/overbits/dss/admin-ui
npm run build
# Serve dist/ folder via nginx, Apache, or CDN

3. Environment Variables

Ensure these are set in production:

• NODE_ENV=production
• DATABASE_URL=<production_db>
• REDIS_URL=<production_redis>
• CONFIG_ENCRYPTION_KEY=<secure_32_byte_key> (NOT the default!)
• JWT_SECRET=<secure_secret>
• ENABLE_REDIS_CACHE=true

4. Database Migrations

cd /home/overbits/dss/server
npx sequelize-cli db:migrate

5. Health Checks

• GET /health returns HTTP 200
• GET /api/projects returns valid response
• Frontend loads at root URL
• Navigation between modules works
• Project selector displays projects
• No console errors in browser

📊 System Status

Backend Services

• Status: ✅ Running
• Port: 3001
• Health: /health endpoint active
• Features:
  • RBAC with Redis caching
  • Configuration cascade (System → Project → User)
  • Discovery worker with component scanning
  • Audit logging

Frontend Admin UI

• Status: ✅ Running (dev: port 3456)
• Build: ✅ Vite compiles successfully
• Architecture: 6 feature modules
  • Projects (📁)
  • Configuration (⚙️)
  • Components (🧩)
  • Translations (🔄) - DSS Principle #2
  • Discovery (🔍)
  • Admin (👤)

🐛 Known Issues (Low Priority)

For Future Sprints

1. Inline Styles: Navigation uses inline styles instead of CSS classes

   • Impact: Makes theming slightly harder
   • Priority: Low
   • Effort: 1-2 hours

2. No Loading States: Module imports show blank screen briefly

   • Impact: Minor UX issue
   • Priority: Low
   • Effort: 2-3 hours

3. No Route Guards: Admin routes lack permission checks

   • Impact: Backend still enforces, but UI allows navigation
   • Priority: Low (backend protected)
   • Effort: 3-4 hours

4. Static Module Placeholders: Modules don't display real data yet

   • Impact: Expected for Phase 1
   • Priority: Phase 2 work
   • Effort: Multiple sprints

---

🎯 Success Criteria

Phase 1 Goals (All Met)

• Replace arbitrary "workdesk" metaphor with feature-aligned modules
• Align UI structure with backend API capabilities
• Provide foundation for implementing real functionality
• Maintain backward compatibility with existing components
• Address all critical and medium priority issues

Production Readiness

• No critical issues remaining
• Application compiles and runs
• Memory leaks resolved
• Error handling improved
• Manual testing completed (pending user verification)

---

📈 Next Phase Planning

Phase 2: Feature Implementation

Priority Order:

1. Projects Module - Create/edit/delete projects, metadata management
2. Configuration Module - Visual editor for 3-tier config cascade
3. Translations Module - CRITICAL: DSS Principle #2 - Zero UI currently exists
4. Components Module - Registry browser, health status, documentation links
5. Discovery Module - Scanner UI, activity logs, analytics dashboard
6. Admin Module - RBAC interface, user management, audit logs

Estimated Timeline: 4-6 sprints (2-3 months)

📝 Notes

Architecture Decisions

• Chose hash-based routing over history API for simplicity
• Web Components pattern for consistency across modules
• Centralized state management via app-store.js
• Dynamic imports for code splitting

Technical Debt

• Consider migrating inline styles to CSS classes
• Add route guards with permission checks
• Implement loading skeletons for module imports
• Add comprehensive unit tests

Security Considerations

• Backend enforces all authorization
• Frontend navigation is cosmetic only
• All API calls require authentication
• RBAC permissions validated server-side
