Nest is a framework for building efficient, scalable Node.js web applications. It uses modern JavaScript, is built with TypeScript (preserves compatibility with pure JavaScript) and combines elements of OOP (Object Oriented Progamming), FP (Functional Programming), and FRP (Functional Reactive Programming).

Under the hood, Nest makes use of Express, allowing for easy use of the myriad third-party plugins which are available.


In recent years, thanks to Node.js, JavaScript has become the “lingua franca” of the web for both front and backend applications, giving rise to awesome projects like Angular, React and Vue which improve developer productivity and enable the construction of fast, testable, extensible frontend applications. However, on the server-side, while there are a lot of superb libraries, helpers and tools for Node, none of them effectively solve the main problem - the architecture.

Nest aims to provide an application architecture out of the box which allows for effortless creation of highly testable, scalable, loosely coupled and easily maintainable applications.


  • Built with TypeScript (compatible with pure JavaScript + Babel)
  • Easy to learn - syntax similar to Angular
  • Familiar - based on well-known libraries (Express /
  • Dependency Injection - built-in asynchronous IoC container with a hierarchical injector
  • WebSockets module (based on, but you can bring your own library, by making use of WsAdapter)
  • Modular - defines an easy to follow module definition pattern so you can split your system into reusable modules
  • Reactive microservice support with message patterns (built-in transport via TCP / Redis, but other communication schemes can be implemented with CustomTransportStrategy)
  • Exception layer - throwable web exceptions with status codes, exception filters
  • Pipes - synchronous & asynchronous (e.g. validation purposes)
  • Guards - attach additional logic in a declarative manner (e.g. role-based access control)
  • Interceptors - built on top of RxJS
  • Testing utilities (both e2e & unit tests)


Install the TypeScript Starter Project with Git:

I am on a mission to provide an architecture to create truly flexible, scalable and loosely coupled systems using the Node.js platform. It takes a lot of time, so if you want to support me, please become a backer / sponsor. I appreciate your help. Thanks! 😍
