Introduction To MERN Stack

To begin with, MERN stands for MongoDB, Express, React, Node. These are the four software tools that combine and make up a stack. In addition, this is a JavaScript Stack that helps in easier and faster deployment of full-stack web applications.


MongoDB is an open-source, NoSQL database that does not require proper relational tables to store the necessary data in it. In addition, its user various formats other than relational tables to store data. Moreover, it does not run on the table-like relational database structure and comes with a different mechanism for storing and retrieving data. MongoDB stores data in a format known as BSON (Binary JavaScript Object Notation) and uses it when storing documents in collections. Above all, this software tool uses JavaScript for coding and supports a flexible document model. To further learn about it, one can visit MERN Stack Training in Delhi. Apart from these, given below are some of the features of MongoDB.

  • Schema-less Database
  • Indexing
  • Document Oriented
  • Faster Solution
  • Scalability
  • High Performance
  • Replication and Highly Available
  • Aggregation
  • Simple Environment Setup


ExpressJS is one of the JavaScript frameworks that help in backend development. Moreover, it is one of the significant functions of MERN & MEAN Stack that helps in building fast and robust productions web applications. In addition, it provides a platform for creating and maintaining robust servers. This software tool is beneficial for easily building and designing web and mobile applications. Above all, it provides server-side logic for mobile and web applications. ExpressJS uses robust web servers to organize an application’s functionality with routing and middleware. Apart from these, given below are some of the features of ExpressJS.

  • Easy web and mobile application development
  • Simple Environmental Setup
  • Easily connects with databases
  • Middleware
  • Built-in Router
  • Single-threaded and Asynchronous.


It is an open-source front-end JavaScript library useful for building web applications. In addition, it is beneficial for creating user interfaces, especially for a single-page web application. Above all, it facilitates a user to build reusable UI (User Interface) components. Therefore, developers use this software tool to create large web applications for changing the data of a page without reloading it. Moreover, it is a very fast, simple, and scalable solution that can also combine with other JavaScript libraries or frameworks. Apart from these, given below are some of the features of React.

  • Easy To learn
  • Simple
  • Data Binding
  • Native Approach
  • Performance
  • Testability


Node.js is an open-source server environment that executes JavaScript code outside a browser. In addition, it is useful in building and developing backend services like net applications, mobile applications. Moreover, it is very simple to use and it helps in agile development and prototyping. Above all, it is beneficial for developing any net service or any net or mobile application. Node.js is capable of running on various operating systems such as Windows, Mac, Linux, Unix, etc. Apart from these, given below are some of the features of React.

  • Easy Scalability
  • Easy to learn and debug code
  • Real-time web apps
  • Caching Advantage
  • Data Streaming
  • Object-Oriented Approach
  • Event-Driven
  • Corporate Support
