Monitoring Setup
# === E-commerce Monitoring ===
# Sentry for Hydrogen (remix.config.js)
# import * as Sentry from "@sentry/remix";
# Sentry.init({
# dsn: "https://xxx@sentry.io/xxx",
# tracesSampleRate: 0.1,
# environment: process.env.NODE_ENV,
# });
# Synthetic Monitor (Better Uptime / Checkly)
# - Check homepage every 30s
# - Check product page every 60s
# - Check add-to-cart flow every 5 min
# - Check checkout redirect every 5 min

เคล็ดลับ
- Fallback: เตรียม Liquid Theme เป็น Fallback เสมอ
- Cache: ใช้ stale-while-revalidate สำหรับ API Response
- Multi-region: Deploy หลาย Region ด้วย Vercel/Cloudflare
- Checkout: Shopify Checkout แยก ถึง Storefront ล่ม Checkout ยังทำงาน
- Test: ทดสอบ DR Drill ทุก Quarter สลับ Failover จริง
