Analytics Dashboard Integration Summary

Date: October 28, 2025 (09:28 Madrid time) Version: 20251028.09:28

✅ All Tasks Complete

1. Turbopack-Only Configuration

File: next.config.ts

Changes: - ✅ Removed webpack configuration completely - ✅ Clean, minimal config for Turbopack only - ✅ No more "Webpack is configured while Turbopack is not" warning - ✅ Monaco Editor works via CDN (configured in middleware.ts CSP)

Before (lines 12-22): 

webpack: (config, { isServer }) => {
  if (!isServer) {
    config.resolve.fallback = {
      ...config.resolve.fallback,
      fs: false,
      net: false,
      tls: false,
    };
  }
  return config;
},

After: 

// No webpack config - Turbopack only!

2. Analytics Dashboard Integration

Location: Moved from /analytics to /dashboard/analytics

Integration Points: 1. ✅ Dashboard Layout (src/app/dashboard/layout.tsx) - Already has Sidebar component

  1. ✅ Sidebar Navigation (src/components/dashboard/Sidebar.tsx)
  2. "Analytics" menu item already exists at line 20
  3. Points to /dashboard/analytics

  4. Uses Activity icon from Lucide React

  5. ✅ Analytics Page (src/app/dashboard/analytics/page.tsx)

  6. Moved from standalone /analytics location
  7. Updated styling to match dashboard (removed gradient, simplified padding)
  8. Now integrated with sidebar navigation
  9. Same functionality: period selector, summary cards, charts, geography

UI Changes: - Removed: min-h-screen bg-gradient-to-br from-gray-50 via-white to-indigo-50 - Added: Clean p-8 padding matching dashboard style - Changed: Title from "Analytics Dashboard" to "Usage Analytics" (h1 3xl) - Result: Seamless integration with Operations Dashboard design

3. Documentation Updates

CLAUDE.md

Added (lines 22-27): 

- **Development server**: `npm run dev` (Turbopack only - Next.js 15)
- **Build**: `npm run build`
- **Production start**: `npm start`
- **Linting**: `npm run lint` (ESLint configured)

**Note**: CodeSlick uses **Turbopack exclusively** (no webpack). The `next.config.ts` is kept minimal and clean.

Updated Analytics Stack (lines 705-717): 

**Analytics Stack**:
- Vercel Analytics (page views, Core Web Vitals)
- PostHog Analytics (user behavior, DAU/WAU/MAU)
- Operations Dashboard (`/dashboard`) - Together.ai costs, Vercel deployments, PostHog metrics
- **Usage Analytics Dashboard** (`/dashboard/analytics`) - ✅ NEW
  - Comprehensive code analysis tracking (lines analyzed, errors by category, geography)
  - OWASP Top 10 categorization with severity breakdown
  - Geographic distribution (country/city tracking with ip-api.com)
  - Language usage trends and quality metrics
  - Period filtering (day/week/month)
  - API endpoints: `/api/analytics/summary`, `/api/analytics/trends`
  - Database: `usageAnalytics` table (68 fields, 5 indexes) on Neon Postgres
  - Non-blocking tracking (doesn't impact analysis performance)

ANALYTICS_SYSTEM_COMPLETE.md

Updated: - URL: http://localhost:3000/dashboard/analytics (was /analytics) - Integration note: "Integrated into Operations Dashboard with sidebar navigation" - UI Design: Added "Accessible via 'Analytics' menu item in dashboard sidebar" - Testing instructions: Updated with dashboard navigation flow - Files modified: Added next.config.ts (Turbopack-only update)

  • Build cache cleared (rm -rf .next)
  • Version.json updated (20251028.09:28)
  • Documentation updated (CLAUDE.md, ANALYTICS_SYSTEM_COMPLETE.md)

🧪 When Dev Server Starts

Test these scenarios:

  1. Dashboard Navigation: 
    npm run dev
# Should NOT see: "⚠ Webpack is configured while Turbopack is not"
  2. Visit http://localhost:3000/dashboard
  3. Click "Analytics" in sidebar
  4. Should navigate to analytics page

  5. Sidebar should highlight "Analytics" as active

  6. Direct URL Access:

  7. Visit http://localhost:3000/dashboard/analytics
  8. Should see analytics dashboard
  9. Sidebar should show on left

  10. "Analytics" menu item should be highlighted

  11. Period Filtering:

  12. Click "Day", "Week", "Month" buttons

  13. Data should update (or show "No data" if fresh)

  14. Analytics Tracking:

  15. Submit code analysis at http://localhost:3000/analyze
  16. Return to http://localhost:3000/dashboard/analytics

  17. Refresh page - should see 1 analysis recorded

  18. API Endpoints: 

    curl http://localhost:3000/api/analytics/summary?period=week
# Should return JSON with summary data
