✨ Enterprise-grade config architecture
🚀 Centralized config library for the entire monorepo
⚡ Environment validation using class-validator
🛑 Fast-failure strategy — fail before boot if app isn’t ready
🔐 Secure handling of secrets in production
📦 Config pattern for Nx + Nest JS
🔥 Avoiding broken deployments

By the end, your app will be bulletproof in production — no mysterious crashes, no missing envs, no silent failures.

🔥 Bonus

I also share my personal fast-fail philosophy so you never ship broken code again.
