What is MERN stack web development?

A full stack web developer is a person who can develop both client or frontend and server or backend software. The MERN stack is an example of full stack web development that consists of the following open-source technologies:

MongoDB: a document-based open source database.

Express: A fast, unopinionated, minimalist web application framework for Node.js.

React: A JavaScript front-end library for building user interfaces.

Node.js: Javascript run-time environment built on Chrome’s V8 JavaScript engine that executes JavaScript code outside of a browser.

In web development process backend consists of a server which will serve up files like html, css and javascript, a database which can store user data such as their logins and passwords. Javascript code interpreted inside our browser, but the JS code was only useful in the browser. It did not have access beyond the browser.

Node.js:

Node.js was made to basically liberate javascript from the browser and allow programmers to use Javascript interact with the computer directly, for example on a server. It’s a low level technology that allows developer to interact directly with the hardware of the computer. Now that means developers can create desktop applications using Node.
