Everything You Should Know About the Well-Known MERN Stack

Developers or businesses seeking MERN stack development are adopting the future of building web apps. The MERN stack consists of a total of four coding languages, similar to one another. The developers can use all four technologies as one for creating diverse web apps and services. 

The four frameworks, technologies, or coding languages in the MERN stack are MongoDB, Express.js, ReactJS, and Node. This is also the full form of the abbreviation MERN. Over time, it has become a popular preference for businesses to develop full-stack web apps. 

This is mostly because the MERN stack allows easy data flow between both the front end and the back end. Thus, it has become a very rewarding career option for most of the young developers out there, as businesses are demanding this skill on priority. 

In this guide, you will get a deep understanding of the MERN stack and all of its associated technological attributes. 

What is the General Understanding of MERN Stack?

MERN stack is the set of several JavaScript technologies used for developing full-stack web apps. The developers use it for creating dynamic web applications that replicate high performance. The working of this stack is approached through the MVC (Model-View-Controller) architecture. 

Here, MongoDB becomes the data model, ReactJS creates the UI, ExpressJS implements the controller, and Node.js acts as the backend runtime environment. In combination, these frameworks deliver a complete full-stack development experience. 

Why Should One Become A MERN Stack Developer?

The MERN stack provides you with a plethora of benefits to the developers. It is scalable, fast, simple, and flexible for a MERN stack developer to personalize the UX and improve the performance of a web app. If you want to build a career out of web app development, it is better to be full-stack to create a rewarding one. 

Learning web development using the MERN stack would enable you with skills to handle both front-end and back-end development together. Here are some of the reasons that explain why you should become a MERN stack developer:

  • Versatility

MERN stack can be used to develop web apps of all types and complexities, from an eCommerce or blogging site to business apps or news portals. 

  • Independent Module Modification or Customization

mern stack development boasts the principles of scalability, high availability, and modularity. Every part of your development project can be modified independently, while the others can remain unaffected. 

For instance, if a bug is identified in one of the modules and needs fixing, it won’t affect the other modules in the setup. But if the bugged module gets patched or replaced, there might be a need for making some changes to other modules.

What are the Perks of Using MERN Stack for Developing Web Apps?

MERN stack brings to you a plethora of web development advantages, some of which include:

1. Open-Source Framework

MERN stack is completely open-source, which means you have access to all codes within. Thus, you can customize the code or tweak it per your needs. 

2. Highly Scalable

One of the best features of the MERN stack is high scalability. As the MERN stack uses MongoDB and Node.js, expanding the business with new web app features or switching between multiple components isn’t much more difficult. It is mostly because of the shared language concept!

3. Enhanced Functionality

The web apps that need enhanced features, such as Active Director or encrypted authentication support, preferably use MERN stack development. Using it, developers will be able to reduce the overall time. 

4. Better Accessibility

The most crucial benefit that helps novice developers use the MERN stack as their primary skill set is its accessibility. It means even though a developer isn’t proficient with a strong coding background, he or she can still get started with MERN stack basics. 

What are the Different MERN Stack Use Cases?

A MERN stack developer uses this framework for developing web apps that operate only with JavaScript functions. It is a naturally expected output because all the components of the MERN stack are based on JS. To help you get an understanding of the application of the MERNS stack, here are some of its user cases:

  • Apps for Tasks and Calendars

MERNS stack can be used for simple development projects such as a calendar or to-do application. Developers can use ReactJS to design the front-end interface of the app. For apps like to-do lists or calendars, MongoDB is another component that helps you get the data, change it, or show it. 

  • Create Forums

You can create an interactive forum, a website, or a social media site that allows people to share messages or communicate with one another. It is yet another popular use case for developers using MERN stack development. 

  • Social Media Product

MERNS stack can also be used for creating social media products, such as small web apps, posts, ads, interactive forums, or others built within the social media page. 

  • eCommerce Websites

The MERNS stack has the ability to help eCommerce platforms create an astounding experience for the end-users. Using React, developers can create attractive catalogs or carts, and Node & Express.js can be used for handling payments, order processing, inventory management, and others. 

  • CMS (Content Management System)

MERNS stack is highly suitable for developers to create CMS platforms for clients. These platforms are meant for creating, managing, and publishing content on your websites. React gives the UI, whereas Node and Express handle the backend functions or database connections. 

Bottom Line

To master MERN stack development, you must have specific SQL, CSS, HTML, Python, and Java skills. Big companies are looking for developers with MERN stack skills to handle their front-end and back-end development requirements as a whole. 

This article gives you a detailed idea of the foundation knowledge you need to become a MERNslS stack developer. But to ensure you master its utilization to the best, you must learn the basics and implement them in as many projects as possible. 

From creating a calendar to creating robust business applications, you must keep testing your limitations and exceeding them to be the best MERNS stack developers.
