Top MERN Stack Development Company in India – MERN is one of the different versions of the MEAN stack, where the primary Angular frontend framework is substituted with React.js. Other versions of the MEAN stack include MEVN, with which any frontend JavaScript can function. So if you are looking for best MERN Stack Development Companies in India then do explore the blog.
What is MERN Stack
MERN stack is a type of JavaScript stack, which is mainly used for quicker and easier deployment of full-stack mobile and web applications. The MERN stack comprises four different technologies;
- MongoDB
- Express
- React
- Node.js
This stack technology is mainly designed to make the process of development much easier and smoother. All of these four stack technologies offer an end-to-end framework to the engineers to work in, and all of these technologies play a vital role in the creation of web applications.
Working of the MERN Stack
In a MERN stack, you can easily construct a three-layered architecture (database, frontend, and backend) by completely using JSON and JavaScript.
React.js Frontend
The top layer of the MERN stack is known as React.js, which is the asserting JavaScript framework for building dynamic web applications in HTML. React.js allows you to create complicated interfaces by using easy components. You just have to connect them to the data located on your backend server, and then render them using the HTML.
The most important part of React.js is managing data-driven and stateful interfaces with minimal pain and code, and it includes all the essential features that you can see in an advanced web framework. It includes features like error handling, excellent support for forms, lists, events, and more.
Node.js and Express.js Server Layer
The next layer is called the Express.js server-based framework, which functions inside a Node server. Express.js is mainly known as a quick, minimalist, and unopinionated web framework for Node.js. It includes powerful models that are used for URL routing and managing HTTP responses and requests.
MongoDB Database Layer
If your web application contains any data like, comments, content, user profiles, events, uploads, etc., then you will surely need a database that can easily function with Node, Express, and React.
In such a case, you will need MongoDB. JSON documents that you have created in your React front end can be delivered to the Express.js server, from where they will be completely processed and stored directly into the MongoDB database for future retrieval.
