Kind: Structured Node.js server framework · License: Open source · Last verified: 2026-09-28

A TypeScript framework for server-side apps built from modules, controllers, and providers wired by dependency injection. Validation, guards, OpenAPI docs, GraphQL, and rate limiting come as first-party packages.

Reach for it when:
- APIs several teams or clients depend on
- Backends that will grow across many domains

Worth knowing: Decorators and dependency injection add ceremony that a small service doesn't need. It runs on Express by default and can switch to a Fastify adapter.
