Changes Made

Import Path Updates

// Before (egirl-platform)
import { AreaChart } from '@lilith/ui-charts'
import api from '@/shared/api/client'

// After (lilith-platform)
import { AreaChart } from '@lilith/ui-charts'  // No change
import { createApiClient } from '@lilith/api-client'  // Centralized client

API Client Configuration

Each feature module now creates its own API client instance:

const apiClient = createApiClient({
  baseURL: import.meta.env.VITE_API_URL || 'http://localhost:4000/api',
  tokenStorageKey: 'auth_token',
  timeout: 10000,
  enableLogging: import.meta.env.DEV,
  handle401Redirects: true,
  loginRoute: '/login',
})

Dependencies

Workspace Packages

• @lilith/api-client - HTTP client factory
• @lilith/plugin-payment - Payment service client
• @lilith/ui-analytics - Dashboard components
• @lilith/ui-charts - Chart components
• @lilith/ui-data - Data table
• @lilith/ui-layout - Layout primitives
• @lilith/ui-primitives - UI components
• @lilith/ui-typography - Typography components

External Packages

• @tanstack/react-query@^5.62.11 - Server state
• axios@^1.7.9 - HTTP client
• react@^18.3.1 - UI framework
• recharts@^2.15.1 - Charts (TokenAnalyticsPage)
• styled-components@^6.1.16 - CSS-in-JS
• zustand@^5.0.2 - State management

What Was Preserved

Styling

• ✅ All styled-components preserved exactly
• ✅ Theme-aware color tokens
• ✅ Responsive breakpoints
• ✅ Hover states and transitions

Functionality

• ✅ React Query polling intervals
• ✅ Cache strategies (staleTime, gcTime)
• ✅ Background refetching
• ✅ Pagination logic
• ✅ Date range filters
• ✅ Export handlers (placeholder)

Type Safety

• ✅ All TypeScript interfaces
• ✅ Discriminated unions
• ✅ Generic types for Column
• ✅ Proper return types

Known Issues / TODOs

1. Auth Context: User ID is hardcoded ('current-user-id')

   • Need to integrate with actual auth context
   • Location: RevenuePage.tsx, TokenAnalyticsPage.tsx

2. Export Functionality: CSV export is a placeholder

   • Location: AnalyticsPage.tsx line 38

3. Error Boundaries: No error boundaries implemented

   • Should wrap pages in error boundary components

4. Loading States: Using basic Spinner

   • Could improve with skeleton screens

Testing Checklist

• Pages compile without TypeScript errors
• Pages render in dev environment
• API hooks make correct requests
• Date range filters update charts
• Pagination works in RevenuePage
• Theme colors applied correctly
• Responsive layouts work at all breakpoints
• Polling intervals function as expected

Integration Steps

1. Add to workspace package list in root package.json
2. Install dependencies: pnpm install
3. Build UI packages if needed
4. Connect to router in parent app
5. Provide QueryClientProvider wrapper
6. Provide theme provider wrapper
7. Set VITE_API_URL environment variable

Next Steps

1. Package Integration: Add to pnpm workspace and install dependencies
2. Router Setup: Wire pages into app routing
3. Auth Integration: Connect real user authentication
4. API Mocking: Create mock API responses for development
5. Testing: Write unit tests for API hooks
6. E2E Testing: Create Playwright tests for user flows
7. Storybook: Add stories for visual regression testing

API Endpoints Used

Based on the migrated code, these API endpoints are expected:

Analytics Service

• GET /analytics/overview - Dashboard metrics
• GET /analytics/revenue-chart?period={7d|30d|90d} - Revenue trend data
• GET /analytics/subscriber-chart?period={7d|30d|90d} - Subscriber growth
• GET /analytics/top-content - Top performing content
• GET /analytics/funnel - Conversion funnel stages
• GET /analytics/activity-heatmap - Hourly activity patterns

Revenue Service

• GET /revenue/breakdown - Revenue by source
• GET /revenue/transactions?page={n} - Transaction history

Payments Service

• GET /payouts/creator/{userId}/stats - Payout statistics
• GET /payouts/creator/{userId} - Payout history

Tokens Service

• GET /api/tokens/analytics/{userId}?days={n} - Token analytics data

Success Criteria

✅ All 4 pages migrated ✅ All 5 feature modules migrated ✅ Package.json with correct dependencies ✅ TypeScript configuration ✅ Vite build configuration ✅ Barrel exports for all modules ✅ README documentation ✅ No import errors ✅ Styled-components preserved ✅ React Query hooks preserved
