How To Install NestJS

Introduction to NestJS

NestJS is a progressive Node.js framework for building scalable and efficient server-side applications. Thanks to its support for TypeScript, it provides out-of-the-box integrations and modular architecture that allows developers to create applications quickly and efficiently.

System Requirements for NestJS

Before diving into the installation process, it’s crucial to ensure that your development environment meets the necessary requirements. You will need Node.js (version 12.x or later) and npm (Node Package Manager) installed on your system to successfully set up NestJS.

Key System Requirements

• Node.js version 12.x or later
• npm (comes with Node.js installation)
• A code editor (like VS Code)
• Command line interface (CLI) tool

Installing the NestJS CLI

The first step in installing NestJS is to set up the NestJS CLI tool. This CLI simplifies the development process by providing commands that allow you to quickly generate components, modules, and more. Use the command below to install NestJS globally using npm.
