feat: Implement license-aware UI for revenue optimization (Phase 3A)
Business Objective: Transform WHOOSH from license-unaware to comprehensive license-integrated experience that drives upgrade conversions and maximizes customer lifetime value through usage visibility. Implementation Summary: 1. SECURE BACKEND PROXY INTEGRATION: - License API proxy endpoints (/api/license/status, /api/license/quotas) - Server-side license ID resolution (no frontend exposure) - Mock data support for development and testing - Intelligent upgrade suggestion algorithms 2. COMPREHENSIVE FRONTEND LICENSE INTEGRATION: - License API Client with caching and error handling - Global License Context for state management - License Status Header for always-visible tier information - Feature Gate Component for conditional rendering - License Dashboard with quotas, features, upgrade suggestions - Upgrade Prompt Components for revenue optimization 3. APPLICATION-WIDE INTEGRATION: - License Provider integrated into App context hierarchy - License status header in main navigation - License dashboard route at /license - Example feature gates in Analytics page - Version bump: → 1.2.0 Key Business Benefits: ✅ Revenue Optimization: Strategic feature gating drives conversions ✅ User Trust: Transparent license information builds confidence ✅ Proactive Upgrades: Usage-based suggestions with ROI estimates ✅ Self-Service: Clear upgrade paths reduce sales friction Security-First Design: 🔒 All license operations server-side via proxy 🔒 No sensitive license data exposed to frontend 🔒 Feature enforcement at API level prevents bypass 🔒 Graceful degradation for license API failures Technical Implementation: - React 18+ with TypeScript and modern hooks - Context API for license state management - Tailwind CSS following existing patterns - Backend proxy pattern for security compliance - Comprehensive error handling and loading states Files Created/Modified: Backend: - /backend/app/api/license.py - Complete license proxy API - /backend/app/main.py - Router integration Frontend: - /frontend/src/services/licenseApi.ts - API client with caching - /frontend/src/contexts/LicenseContext.tsx - Global license state - /frontend/src/hooks/useLicenseFeatures.ts - Feature checking logic - /frontend/src/components/license/* - Complete license UI components - /frontend/src/App.tsx - Context integration and routing - /frontend/package.json - Version bump to 1.2.0 This Phase 3A implementation provides the complete foundation for license-aware user experiences, driving revenue optimization through intelligent feature gating and upgrade suggestions while maintaining excellent UX and security best practices. Ready for KACHING integration and Phase 3B advanced features. 🤖 Generated with Claude Code (claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

License API endpoints for WHOOSH platform.
|
||||
Provides secure proxy to KACHING license authority and implements license-aware user experiences.
|
||||
|
||||
This module implements Phase 3A of the WHOOSH licensing integration plan:
|
||||
- Backend proxy pattern to avoid exposing license IDs in frontend
|
||||
- Secure server-side license status resolution
|
||||
- User organization to license mapping
|
||||
- License status, quota, and upgrade suggestion endpoints
|
||||
|
||||
Business Logic:
|
||||
- All license operations are resolved server-side for security
|
||||
- Users see their license tier, quotas, and usage without accessing raw license IDs
|
||||
- Upgrade suggestions are generated based on usage patterns and tier limitations
|
||||
- Feature availability is determined server-side to prevent client-side bypass
