Architecture of a Modern Enterprise Node js Application
summary
Describes using a dedicated BFF layer written in TypeScript on NestJS for large corporate frontends: it server-renders HTML for SEO, aggregates multiple backend calls into a single gateway, and centralizes business rules while leaving small view logic to the client. Discusses trade-offs and operational concerns—Node.js handles many concurrent requests but can block on CPU-bound work, GraphQL risks N+1 queries unless optimized, and alternatives like Deno or Graal exist—and advocates a layered hexagonal/clean architecture with dependency injection to enable safe migration in production.
