Phase 3.6: Development Approach

Rapid Development Strategy

1. Start with Web (faster iteration)

   • Get feedback on UI/UX
   • Validate functionality
   • Then adapt to mobile

2. Component Library

   • Pre-built components
   • Consistent design
   • Faster development

3. API-First

   • Backend already complete
   • Focus on UI layer
   • No backend delays

4. Progressive Enhancement

   • Core features first
   • Add polish later
   • Ship quickly

---

Phase 3.7: API Integration

Base Configuration

const API_BASE = 'http://solaria:8001/api';

Endpoints Available

Authentication

• POST /auth/register
• POST /auth/login
• GET /auth/me

Medications

• GET /medications
• POST /medications (with pill_identification)
• GET /medications/:id
