From da8657765f2a0a738a714e2218b65a8e01d6f32a Mon Sep 17 00:00:00 2001 From: Claude Code Date: Tue, 4 Aug 2026 15:49:50 +0900 Subject: [PATCH] fix: UNIFIED_SERVICE_INTEGRATION - Correct Single Domain Architecture MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CORRECTION: Same Domain Integration (Not Subdomain) User Question: 통합됐다는데 도메인이 왜 다른거야? (Why different domains if integrated?) Issue: Previous design used separate subdomains - Frontend: kartsell.taxbaik.com - API: api.kartsell.taxbaik.com Problem: Not truly unified Solution: Single Domain Integration - kartsell.taxbaik.com/ ├─ / → Frontend (Vue app) └─ /api/ → Backend API (Nginx proxy) Architecture: ┌────────────────────────────────────────┐ │ kartsell.taxbaik.com (Single Domain) │ ├────────────────────────────────────────┤ │ Nginx (HTTPS, Port 443) │ │ ├─ / → Frontend (Vue) │ │ └─ /api/ → Backend (.NET 5002) │ └────────────────────────────────────────┘ ↓ PostgreSQL DB Nginx Configuration: location / { root /var/www/kartsell/frontend; try_files $uri /index.html; # SPA routing } location /api/ { proxy_pass http://localhost:5002/; # Headers, buffering, etc. } Frontend Code: No changes needed - Uses relative paths: /api/... - Nginx handles proxy transparently - Same domain = no CORS issues Benefits: ✅ Single domain: kartsell.taxbaik.com ✅ Unified service: Users see one website ✅ No CORS: Same-origin requests ✅ Industry standard: Nginx reverse proxy pattern ✅ Professional: Clean architecture Deployment Flow: 1. Build frontend: pnpm build 2. Deploy: /var/www/kartsell/frontend/dist/* 3. Deploy backend: dotnet publish 4. Configure Nginx: See config in doc 5.
