Type-Safe Environment Configuration: Preventing Production Crashes with Zod
Zod로 환경 변수를 타입 안전하게: 배포 후 런타임 충돌 방지
Why it matters
Environment variable misconfigurations cause mysterious production crashes that developers only discover after deployment. Zod enables fail-fast validation at startup, catching errors with clear, actionable messages before the app serves any requests. This pattern is essential in modern frameworks like Next.js where environment behaviors differ between server and client contexts.
