Nest (NestJS) is a framework for building efficient, scalable Node.js server-side applications. It uses progressive JavaScript, is built with and fully supports TypeScript (yet still enables developers to code in pure JavaScript), and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming).
Under the hood, Nest makes use of robust HTTP Server frameworks like Express (the default) and optionally can be configured to use Fastify as well!
Nest provides a level of abstraction above these common Node.js frameworks (Express/Fastify), but also exposes their APIs directly to the developer. This gives developers the freedom to use the myriad of third-party modules that are available for the underlying platform.
In recent years, thanks to Node.js, JavaScript has become the “lingua franca” of the web for both front and backend applications. This has given rise to awesome projects like Angular, React, and Vue, which improve developer productivity and enable the creation of fast, testable, and extensible front-end applications. However, while plenty of superb libraries, helpers, and tools exist for Node (and server-side JavaScript), none of them effectively solve the main problem of Architecture.
Nest provides an out-of-the-box application architecture that allows developers and teams to create highly testable, scalable, loosely coupled, and easily maintainable applications. The architecture is heavily inspired by Angular.

My name is Azim, I love creating solutions. It just so happens I am a developer by profession and I get to solve problems every day. I couldn't be happier. I learned computer programming from Sheridan College. I took my studies further by doing what most developers do, view as many tutorials and work with as many frameworks and new technologies as possible. I work at Lazer Technologies as a React Native developer.
I spend my off time with my family. I am a father of two. My wife and I are kept busy by these two. I also enjoy doing origami and playing some Mario games on our Nintendo Switch with my children.
