General Info

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! - Source

Prerequisite

• Minimum NodeJS with version >= 16

Installation

Setting up a new project is quite simple with the Nest CLI. With npm installed, you can create a new Nest project with the following commands in your OS terminal:

npm i -g @nestjs/cli
nest new nest-be # example project-name

HINT

To create a new project with TypeScript's stricter feature set, pass the --strict flag to the nest new command.

After the installation, you'll see the result like this.
