MERN STACK - What is MERN Stack?

Hello Friends,

Welcome to code with Chakri blog.

I am Chakrapani Upadhyaya a full stack engineer.

In this article, you will learn that what is MERN? stack and why we need it.

What is MERN Stack?

MERN Stack is a combination of powerful and robust technologies that are used to create highly scalable web applications. It consists of M==>MongoDB, E==>Express JS, R==>ReactJS, and N==>NodeJS as its working components.

MONGO DB:

MongoDB is a No-SQL database used to store the application data and it is a document-oriented.

EXPRESS JS :

Express JS is a web application framework designed to support and host Node.js projects. Express JS manages the workflow between the front-end and the 

database and offers a smooth and secure transfer of data. 

ReactJS: 

A library created by Facebook. It is used to build UI components that create the user interface of the single page web application.

NodeJS: 

The JavaScript runtime environment. It is used to run JavaScript on a machine rather than in a browser.

Why We need MERN and Why it is so popular?

There are various stacks that are similar in composition to the MERN stack, including the MEAN and MEVN stacks.

• The MERN stack is popular because it is a combination of four powerful technologies: MongoDB, Express.js, React.js, and Node.js. Together, these technologies make it easy for developers to build full-stack web applications quickly and efficiently. 

• All the technologies in the MERN Stack are open source, which means they are free to use and have a vast community of developers who contribute to their development.

• MERN Stack is entirely depends on Javascript, Hence there is one programming language for User Interface and Backend(server side).

          Other programming like ASP.Net and Java uses Javascript for User interface and C# or Java for              server side, Hence we need to maintain two languages(Javascript and C#/Java) here.

• MERN Stack is highly scalable, which means it can handle large amounts of data and traffic. It is an excellent choice for businesses that expect their web applications to grow and expand.

Some Important difference between MERN and MEAN stack shown below.

Overall, MERN stack is a powerful and flexible stack that can be used to build a wide range of web/mobile applications. But, it's important to note that there is no one is "best" stack for web development, as the choice of stack depends on the specific requirements of the project and the preferences of the development team.
