Difference between MEAN Stack and MERN Stack

  • Last Updated : 06 Nov, 2020

In the field of web development, full-stack development is playing a vital role. A full-stack development provides a solution for perfect solutions for front-end, back-end, testing, mobile application. In today’s world, the demand for a full-stack developer is rising tremendously. A full-stack developer can take care of the entire design structure of a project. There exist different full-stack development frameworks like MEAN stack and MERN stack. Now let us understand the variations in both of them.

MEAN stack: MEAN is an abbreviation that stands for MongoDB, ExpressJS, AngularJS, Node.js. This framework provides quick and easy development of web and mobile applications. The main components of MEAN are as follows-

  • MongoDB: It is used to store the data of back-end applications as JSON files.
  • ExpressJS: It is a back-end application that runs on top of Node.js.
  • AngularJS: It is the front-end framework that runs the code in the browser.
  • NodeJS: It provides runtime system for JavaScript on the back-end web application.

One of the prominent advantages of using MEAN stack is that the whole code is in JavaScript. So, it is easy for beginners to explore and learn. Also, its unified offerings can significantly reduce development time and cost. The MEAN stack contains various supporting libraries and reusable modules which deliver a scalable minimum viable product.

Working of MEAN stack: The MEAN stack architecture is used to build web applications in JavaScript, and handling JSON, incredibly easy.



Angular.js front end: Angular.js is at the top of the MEAN stack. It is a self-styled “JavaScript Framework”. Angular.js allows you to extend your HTML tags with metadata to create dynamic, interactive web experiences in much more powerful ways.

Express.js and Node.js Server Tier: Express.js is the next step of MEAN stack, running on a Node.js server. Express.js is a fast, minimalist web framework for Node.js. Express.js has powerful models for URL routing and handling HTTP requests and responses.

MongoDB Database Tier: If we need to store any data, then we need a database like MongoDB. JSON documents created in Angular.js front end are sent to the Express.js server, where they are processed and stored directly in MongoDB for later retrieval.

MERN stack: MERN is an abbreviation which stands for MongoDB, ExpressJS, ReactJS, Node.js. This framework also provides quick and easy development of web and mobile applications using java as its main component. Main components of MERN are as follows.

  • MongoDB: It is a document-oriented No-SQL data store used to store back-end applications.
  • ExpressJS: It is a layered framework built on top of NodeJS that takes care of the website’s back-end functionality and structure.
  • ReactJS: It is a library that facilitates creating the user interface components of single-page web applications.
  • NodeJS: It is a runtime environment capable of running JavaScript on a machine

Working of MERN stack:

React.js front end: React.js is at the top of the development stack. It is declarative JavaScript framework for creating dynamic client-side applications. React.js let us build up complex interfaces through simple components, connect them to data on our backend server.

Express.js and Node.js server tier: It plays same roles in MERN stack as in the MEAN stack as mentioned above.

MongoDB Database tier: It plays the same roles in the MERN stack as in the MEAN stack as mentioned above.
