Editorial take
Why it stands out
Graduate to NestJS or Fastify when structure and performance guardrails need to be enforced org-wide.
Tool profile
Minimalist HTTP router for Node—middleware, JSON APIs, and the default starting point before you reach for heavier frameworks.
REST and JSON APIs with custom architecture
Express stays deliberately small: routing, middleware, and HTTP helpers without dictating your ORM or folder layout. It is free OSS; you pay for servers and databases. It belongs in backend frameworks when you want maximum control, quick prototypes, or a stable base to incrementally structure larger services.
