Learn NestJS from Scratch

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 which are available for the underlying platform.

Philosophy

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.

Who is this course if for

• Any developers willing to apply TypeScript on the back-end

• Developers eager to learn how to develop performant, secure, and production-ready REST APIs following best practices

• Developers who want to follow building a practical, real-world application from zero to production

• Front-end developers who want to move to the back-end development
