NestJS

NestJS is my default framework for backend services that need to stay maintainable as a team and a codebase grow. This hub works through the building blocks — modules, providers, guards, interceptors, and pipes — and then the harder production questions: transaction boundaries, validation, testing, and the folder structure that survives a second year.

It draws on the NestJS Production Guide series and connects directly to the Node.js, PostgreSQL, and Security hubs.
