Hit Enter if you want to keep the default. It will then ask you some questions about the package name, version, entry point, and more. To create a project folder, enter the folder through the terminal, then run $ npm init. To begin our MERN stack tutorial, we’ll show you how to set up a server with Express.js and Node.js. The objective is to develop a simple project with the best possible structure so that you can use it as a boilerplate and elevate your MERN stack projects to meet industry standards. This demo is designed to highlight the MERN setup. Many developers fail to be good MERN stack developers because they lack the fundamental knowledge of JavaScript. So, before learning technologies like React or Node.js, it is important to ensure that your fundamentals are strong. However, it takes time to become a good MERN stack developer. Learning the MERN stack will help you become a full-stack developer, which is in high demand. These statistics should give you a clear idea of how stable and popular these technologies are. About 21 million websites use React to power their frontend. And MongoDB is also one of the most popular databases for developers. Node.js and React rank as the two most popular web frameworks and technologies, according to the most recent Stack Overflow developer survey. MongoDB, Express.js, and Node.js help you build the backend of an application, while React powers the frontend. Node.js: An open source, cross-platform, JavaScript runtime environment that executes JavaScript code outside of a browser.React: JavaScript library for building user interfaces.Express.js: A web application framework for Node.js.MongoDB: A cross-platform document-oriented database program.The phrase MERN stack comprises the following technologies that allow for faster application development: Once both are complete, we’ll connect the frontend to the backend. After that, we’ll walk you through building the frontend, using React to build our user interfaces. To demonstrate how the MERN stack works, we’ll first configure the server side by connecting Node.js and Express.js to MongoDB on the backend. We’ll outline the basics of the MERN stack and demonstrate how to use it by developing a simple CRUD application from scratch. This tutorial is all about understanding the MERN stack. Editor’s note: This MERN stack guide was last updated on 29 November 2023 to fix code errors and provide insights into deployment strategies for MERN apps.
