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: A NoSQL, document-oriented database.
Express.js: A server-side framework for building web applications.
Working of MERN stack:
React.js front end:
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.
Advantages of MERN stack:
Community support: React, one of the components of the MERN stack, has a large and active community of developers who contribute to its development and improvement.
Flexibility: React is a lightweight and flexible option compared to Angular, making it a great choice for building dynamic user interfaces.
Performance:React is known for its fast performance and ability to handle large and complex applications, making it a great choice for building high-performance web applications.
