2. Overview :
Writing software applications has never been easier, thanks to the rise of various frameworks
and development tools that have simplified the process over the years. One such toolchain,
the MERN stack (MongoDB, ExpressJS, ReactJS, NodeJS), allows developers to build and deploy
web applications quickly and efficiently by utilizing its core components.
Using the MEAN Stack (MongoDB, ExpressJS, NodeJS, and AngularJS) has been an increasingly
popular way to create web applications due to its productivity and robustness. The MERN
stack represents MongoDB, ExpressJS, NodeJS, and ReactJS. This article will demonstrate how
to build a simple real-time chat app with MERN stack using JavaScript and React.js from
scratch. We will also cover how to structure your application using ES6 modules and Babel.

3. What is MongoDB?
MongoDB is a powerful document-oriented database system. It has an index-based search
feature that makes data retrieval quick and easy. MongoDB also offers a scalability feature,
allowing it to handle large-scale data.
Developers can run their own MongoDB server on their computer for local development
purposes or use a cloud-based service such as AWS’s RDS. There are various tutorials
available on the internet on how to set up your server with specific instructions for Windows
or Mac OS X operating systems.

4. What is ExpressJS?
ExpressJS is a web application framework for Node.js. It is designed for building web
applications and APIs. ExpressJS provides features that make it easy to create web
applications. It includes a router, middleware, and an HTTP server. ExpressJS is open source
and released under the MIT license. It has over 120,000 GitHub stars on GitHub.
ExpressJS was originally developed by TJ Holowaychuk in 2009 and was later maintained by
StrongLoop. In November 2017, IBM acquired StrongLoop as part of its purchase of Red Hat’s
technologies portfolio, which included Red Hat’s JBoss Middleware business unit.

5. What is React?
React is a JavaScript library for building user interfaces. It lets you create reusable
components, making your code easy to read and maintain. Plus, React is fast and can be used
on the server and client sides. In short, React is awesome! We love it because it’s an easy way
to write readable, modularized code.
One of the best features of React is that it doesn’t just support Web development; React also
runs natively on Android and iOS mobile devices, with new versions being released soon for
Windows Phone 8/8.1 and BlackBerry 10 operating systems.

6. What is Nodejs?
Nodejs is a powerful JavaScript runtime built on Chrome’s V8 engine. It is used for developing
server-side applications and networking applications. Nodejs is open source and cross-
platform. It has an event-driven architecture that makes it efficient and scalable. Nodejs
applications are written in JavaScript and can be run on any platform that supports Nodejs.
The real power of Nodejs lies in the asynchronous execution, which results in non-blocking
I/O operations. With this, developers get increased scalability because the process doesn’t
need to wait for a single operation to finish before starting another one.

7. MERN Benefits: Top Benefits Of Using
MERN Technology
Open-Source Technology
Allows You to Build Fast
Easy to Use
Allows for easy scalability
Provides a flexible framework
Great Community Support
Full-Stack Development
MERN (MongoDB, ExpressJS, React Native, and NodeJS) offers many benefits over
competing technologies; here are some of the top benefits that you may find useful.

8. Open-Source Technology
The MERN stack is a JavaScript-based open-source platform for developing web applications.
It is composed of MongoDB, Express.js, React.js, and Node.js. This stack can be used to
develop Single Page Applications (SPAs).
It uses JavaScript on both the front-end and back-end. This makes development faster and
easier as you only need to know one language instead of two or more.

9. Allows You to Build Fast
The main benefit of using the MERN stack is that it allows you to build fast. You can use
JavaScript for the front and backend, so you don’t have to learn two different programming
languages.
Plus, all the components of the MERN stack work well together, so there’s less debugging and
troubleshooting required. The result is a faster, more efficient development process.

10. Easy to Use
The main benefit of the MERN stack is that it is easy to use. This is because all four
technologies used in the stack are JavaScript-based.
This means developers only need to know one language to work with the entire stack. In
addition, all four technologies are well-documented and have a large community of
developers who can offer support.

11. Allows for easy scalability
The modular nature of a MERN stack application allows for easy scalability. Scaling an
application is important for any business as it allows the company to grow without facing
performance issues.
A MERN stack application can be scaled by adding more servers or by adding more features
to the existing codebase.

12. Provides a flexible framework
The MERN stack provides a flexible framework for developers to work in. This means that
developers can choose to use the language and tools they are most comfortable with, leading
to more efficient and effective development.
Additionally, using JavaScript on both the front-end and back-end allows for full-stack
development, which can make development faster and easier. The MERN stack also includes
a wide variety of open source libraries, which can help speed up development time.
These libraries provide a wealth of functionality that would otherwise need to be built from
scratch, saving valuable time and resources.

13. Great Community Support
The MERN community is large and passionate, and because the technology is relatively new,
there are many opportunities to get involved and make a name for yourself.
The community support is great for finding answers to problems, sharing code snippets, and
getting project feedback.

14. Full-Stack Development
The MERN stack is a JavaScript-based web development stack that enables full-stack web
development. You can create scalable, feature-rich web applications using the four main
technologies involved in the MERN stack.
When combined with Node.js, Express provides an extensible web application framework to
build server and client code for dynamic content generation and rendering on the fly; React
for building user interfaces; Redux for managing state; and MongoDB to store data. MERN
helps developers build fast websites without compromising scalability or functionality.

15. Let’s Wrap Up:
The MERN stack is a popular choice for web development and for a good reason. It offers
many benefits, including a reduced learning curve, improved performance, and increased
efficiency.

everything you need to know, from choosing the right tools to set up your development
environment. If you want to hire MERN Stack developers, feel free to contact us.
