nvm allows this exceptional facility of installing and using different versions of nodes very quickly using the command line. When we want to use different versions of node js at different times, we can use nvm.

Install NVM (Node Version Manager)īefore we install node js and npm, let's know this specific term called 'nvm' which is nothing but a command-line tool known as Node Version manager.

There are many other dependencies and databases (for example, My SQL Server, Oracle, PostgreSQL, MongoDB LevelDB, etc.) like authentication engines, database drivers, etc., which are required in the application and they can be imported into the application development environment with the help of npm (Node Package Manager). As Nodejs is supported, so are npm and Express.js (Express is a backend web application framework for Node.js).

Specifically, Windows, Mac OS, and many Linux distributions support Node.js. Nodejs is supported on all the major operating systems out there. What are the Supported Operating Systems? Remember that we don’t have to install node js and npm separately, we just need to install node js as it already includes npm. When we install node js, npm (Node Package Manager), and/or Express Application Generator (if required), we simply refer to this newly formed development environment as an Express development environment. What is the Express Development Environment? It will be great if you have basic knowledge of frontends like HTML and CSS, as this can help you in creating basic web pages for displaying data. You should also know the normal software installation process. Prerequisitesīefore moving ahead, make sure you know the basics of JavaScript and backend web development like HTTP requests, what is a web server and databases. This article will discuss how to install Node js and Set up a Node.js development environment. We use npm (Node Package Manager) for handling various dependencies of our application. Its purpose is to execute the JavaScript code outside the browser window. It is used in the backend development of various web applications. Node.js is an open-source and free-to-use server-side runtime environment built on Chrome’s V8 JavaScript engine.
