Importance of MERN stack and its Future Prospect

MERN Stack stands to be the abbreviated acronym of Mongo DB, Express(.js), React(.js) and Node(.js). These four technologies also make up the backbone of MERN Stack. With technology starting to dominate our lives, web and mobile applications are becoming the one-stop solutions for many things— from buying household groceries to purchasing international flight tickets.

However, do you know how does a developer constructs a web-application? Well, if you don’t know, then the answer to this is that— a developer makes use of a ‘Stack’ to develop such web apps. MERN Stack is one of the favorites of Technological developers. With the help of MERN Stack, one can create a 3-tier architecture (Frontend, Backend, and Database), using only JavaScript and JSON. Also, MERN developers enjoy the growing market demand to bank upon their expertise. The same fetches them a handsome salary and multiple job role options, too.

We here at AddSkill, have compiled point-to-point data at your hand on MERN Stack, so that you can get a 360 knowledge about the rising importance of the Stack, including its prospects. In this write-up we shall delve deep, into why MERN Stack development can be your choice, practically stating and analyzing its needs and future scenarios.

However, we understand not to state the relevant nitty-gritty about MERN Stack, viz., what it is made up of, why is it in use, etc. would not clear the doubts of your mind. So, before we jump in discussing the importance and future aspects of MERN, here goes a brief discourse of it catering to relatable issues other than the mentioned two topics.

What MERN Stack Is?

MERN Stack is one of the several variations that MEAN Stack has. It is a combination of MongoDB Express and Angular Node, where the traditional structure of Angular.js frontend framework is replaced with React.js. Other variants of it include MEVN (MongoDB, Express, Vue, Node), and any frontend JavaScript framework can work over here.

MERN is made up of four key technologies and they are as follows—

  • MongoDb: It works as a document database
  • Express(.js): It is a Node.js web framework
  • React(.js): It is a client-side JavaScript framework
  • Node(.js): It acts as a premium JavaScript web server.

How Does MERN Work?

The MERN Stack allows one to easily construct a 3-tier design (Frontend, Backend, and database) using JavaScript and JSON.

React.js Front End

The top structure of MERN is REACT.js, the declarative JavaScript framework for creating a dynamic client-side application in HTML. React permits one to build up complex interfaces with the help of simple components, connecting the data with one’s backend server and rendering them as HTML. React is apt for a modern web framework as it is stateful, data-driven, having interfaces with minimal code and minimal pain—that makes it worthy for forms, error handling, event list, etc.

Express.Js and Node.js Server Tier

The next part is The Express.js server-side framework that runs inside a Node.js server. Express.js is a platform for Node.js that operates itself in a fast, unopinionated, minimalist web framework model. And this is exactly what Express.js needs to run its powerful models for URL routing, to match an incoming URL with a server function or handling HTTP requests and responses.

By designing XML HTTP requests with the help of Angular.js front end one can connect Express.js functions with it, to power an application. Interestingly those functions in turn make use of MongoDB’s Node.js driver.

MongoDB Database Tier

When an application stores any data, for. E.g., User profiles, uploads, events, etc. then it becomes necessary to use a database that can easily work with Angular, Express, and Node.

Here, in this case, a developer chooses to use MongoDB. JSON documents that are created inside Angular .js front-end, can be sent to the Express.js server— where the valid ones from them get processed, and then they are directly stored in MongoDB for later references.

The Importance of MERN Stack

MERN Stack uses MongoDB. It acts as a document database at the root of MERN Stack. MongoDB was primarily designed to store JSON data natively. However, we can also say MongoDB uses a binary version of JSON, called BSON. The total command line of MongoDB interface with its query language (that is either MQL or MongoDB query language) and it is completely built on JSON or JavaScript. Such technologies make MERN Stack a good catch for developers to learn and also the technology used over here is swift.

More to it, MongoDB collabs very well with Node.js. Such collaboration makes storing, manipulating, and representing JSON data at every tier of one’s application incredibly easy. For cloud Native application MongoDB is also handy. It gives one an auto-scaling MongoDB cluster on the cloud provider of one’s choice and is as easy as a few buttons clicks.

Express.js (that runs on Node.js) and React.js make MERN stack a Full-stack application too. Express.js is a server-side application framework that tracks HTTP requests and responses and makes the mapping of URLs easier to server-side function. React.js is a part of the fronted JavaScript framework. It helps to build interactive user interfaces in HTML and facilitates communication with a remote server.

This type of combination directly points out that JSON data floats naturally from front to back which makes it faster and reasonably simple to debug. Plus, the knowledge of one programming language and the JSON document structure is enough to understand the whole system.

Therefore, discussing the possible areas where MERN Stack claims an edge over other technologies we come to an understanding of why MERN is so important for today’s developers to learn, who are looking to move quickly, particularly for those with React.js experience.

Future of MERN Stack

MERN Stack is ideally suited for cases that heavily use JSON technology, are cloud-native, and also have a dynamic wave interface in it. Thus, many projects are banking upon the benefits of MERN Stack. These projects are-

  • Workflow Management
  • News Aggregation
  • To-do apps with Calendars
  • Interactive forums and social products.

The main advantage of MERN is that everything in a line of code is written in JavaScript. JavaScript is an accepted universal programming language since it is used for both server-side and client-side. In other words, it is used for both frontend and backend side. Because of this, there is zero need for context switching in MERN Stack. Plus, for developers, only one language, i.e., JavaScript is enough to operate MERN Stack—making it a million times easier. These things only open possibilities for MERN Stack to grow more and more in the future, which will be highly tech-driven.

Node.js also experiences far more potential in conjunction with the MERN Stack. It is a technology that has been built on chrome’s JavaScript runtime, to build more conducive fast operating network applications with easy scalability Node.js’s efficiency and ease make it a perfect platform for a real-time application that runs across distributed devices, especially in people who use and need many data.

Therefore, we can infer from this discourse that working in MERN Stack delivers powerful results, simply and efficiently. Knowing the way around handling MERN Stack is an important skill, since building and deploying solid MERN apps is likely to take place in huge amount in future which will be controlled by technologies, without a single doubt.

Conclusion

We have logically analyzed why most likely MERN Stack will experience a flood in its use in the future. To handle MERN Stack effici
ently, one needs not only the knowledge of JavaScript, but he/she should be familiar with ES6 fundamentals, along with the basic concepts of React.js and Node.js.
