Introduction

MERN or MongoDB, Express, React, and Node combo of robust technologies enables users to enjoy all the considerations related to web development. Using the above-said technologies, we can efficiently work at every stage of web development, client-side, server-side or database-related services and requirements.

It is considered the complete solution for all your needs and follows a three-tier structural pattern, i.e., Front-end, application and database tiers all need to be under one roof. Earlier known as MEAN, abbreviated for MongoDB- Express- Angular –Node, now, with the evolution of technology, React has replaced Angular but has a similar background to JavaScript.

What is MERN

MERN comprises the best technologies, namely, MongoDB for database requirements, Express for web framework based on Node.JS needs, React, a JavaScript framework used on the Client side and Node.JS, the best JavaScript-based web server.

The middle tier or Application tier consists of Express and Node. If you are working with JavaScript and JSON technologies, then Node.JS is the best and most powerful platform based on JavaScript.

 

Why is it important?

With the evolution of modern-day technologies, businesses have parallelly changed accordingly. With React coming into the picture, the popularity of the MERN has also increased. It is considered the most promising and robust technology that makes your business more secure than ever. Its customer-friendly approach makes it the most demanding set of technologies, making it the present and future technology. Web Development has not been made so secure and sophisticated that it will raise the bar of your expectation every time you find a masterpiece.

Features of MERN

Collective features are useless unless the elements are discussed independently. These are as follows.

MongoDB

•     Database without a defined schema: it can easily manage multiple data types and documents with ease and flexibility.
•     Indexing data is so simple that it instantly fetches the required data from the repository. Therefore, primary and Secondary indices are the most crucial categorization feature that set it apart from others.
•     Data is stored as Documents and not in traditional tables. Instead, documents are stored in the Key-Value pair.
•     With Key value pairs, it is not only easy but also faster. It has a tremendous horizontal scalability potential. Sharding is also unique, distributing big data on multiple servers in smaller chunks (Shards) of data. The data can be accessed via Shard Key.
•     MongoDB eases the task of Replication and availability of data by storing a copy of data on various servers simultaneously. In case of hardware failure, your data can be accessed from other servers.

Express

•     Easy with strong APIs
•     Easy to go with HTTP and NodeJS by adding various functionalities to the existing technologies.
•     Best for mobile app development: With a colossal repository of third-party apps for better results for your project.
•     Easy and Smooth creation of Representational State Transfer Application Programming Interface (REST API) ensures excellent flexibility and functionality and uses HTTP for fetching data.

React

•     Simple to write and understand. the best Open Source JavaScript frameworks for front-end and best for building Mobile Apps.
•     Easy data binding with one-way data binding approach, it is easy to debug code and the application as a whole.
•     The cross-platform approach has allowed React to develop the fastest among its competitors. In addition, it has allowed the code to be reused to create applications for multiple platforms like iOS, Windows, and Web applications.
•     React is very easy to test. There are some functionalities that test your app rigorously, with some test cases that push the limits of your app.

Node

•     Real-Time Web app development is too in demand, and to achieve the proper and deep analysis of data in Real-Time is a work of art and Node achieves it hassle-free.
•     Caching even a single module is one feature that makes it the best in the business. There is no need to re-execute the entire code again and after modifications.
•     Data streaming is quick and even allows it to stream interactive files like audio and video files.
•     Object-oriented nature makes it more secure. It uses most of the secured features of OOPS to make your application secure and feature-oriented.
•     Backing up corporate companies like Google, Microsoft, Paypal, and many more uses Node.js to develop the applications.

Pros of MERN

•     Open source makes it one of the technologies with full community backing. Therefore You will get a resolution to your issue in no time.
•     Using MERN makes the creation and development of smaller apps much faster as it requires big time to develop because of minute details.
•     Smoother (Model View Controller) MVC support architecture ensures that the logic section does not get messed with in the presentation layer.
•     Cost-effective: All the mentioned technologies in MERN are built on JavaScript, which requires comparatively less investment and gets you more results.
•     Web Applications developed via MERN are SEO(Search Engine Optimization) friendly. Easy to perform SEO operations for sites like Google and Yahoo.
•     Better performance indicates faster response between all three sections, i.e. Front-end, database and Backend and creation of API (Application User Interface) to strengthen the security of your web app.
•     Applications based on MERN are developed faster and, therefore, the delivery. Also, the modifications are easy, like snapping of fingers.
•     As MERN is written only in JavaScript. Therefore it is easy to manage and comprehend all the sections altogether. Consequently, switching between both sides, Client and Server, is effortless.

 

Cons of Mern

As we know that MERN is accepted worldwide as its applications are endless. So the disadvantages are significantly less and with further development of the same will further reduce its shortcomings. Some of the cons are mentioned below.

•     Productivity

React is only a library, and it uses multiple libraries that limit the developer’s authority over it and therefore require more dedicated effort, especially in React code.

•     Large-Scale Applications

MERN is perfect for developing small applications, but developing Large Scale Applications is not the work of MERN. However, with the further Research and Development of MERN technologies, it will be extended to make Large Applications.

•     Error prevention:

MERN is more prone to Coding typing errors because Node.js in MERN does not use TypeScript to prevent coding errors as it s used by Angular in MEAN. React is lagging in these terms.

 

Future of Mern

Now all the spheres are touched by modern technologies of today. Following are the cases in which MERN can be critical.

AI (Artificial intelligence) is the talk of today and will be game-changing in almost all spheres of applications. Express and Node make it easy to adapt to the changes because of strong community support from across the globe.

Blockchain is best for decentralizing databases and making them further secure. MongoDB is one such technology in which a lot of work needs to be done, and the inclusion of Blockchain will only cement its position in the scene.

AR and VR (Augmented Reality and Virtual Reality)

AR and VR are the most sought-after technologies of the new age and have revolutionized business trends. These technologies provide a more immersive experience, and MERN, especially React, can catch the positives of MR (Mixed Reality= Augmented Reality + Virtual Reality). Whether in healthcare, education or any other sector, this has more potential than any other technology.

IoT (Internet of Things)

there has been an exponential increase in Internet of Things applications, and the business has grown to an unmatched level. Qualities like Data analysis and dealing with data from multiple physical sensors lead to better decisions and understanding of data and, ultimately, the applications.

PWA (Progressive Web Applications)

The importance and demand of PWAs have seen tremendous growth in recent years. It combines all the features of traditional and modern-day applications like Mobile and Desktop Applications into one. PWAs are the best and most modern ways to improve businesses by improving retention and conversion rates.

Trending Programming Languages

JavaScript can be called the Modern day Language of the Internet, and multiple applications can be obtained from one language. On the other hand, React is one of the universal languages to develop cross-platform applications without writing another code for different platforms.

Conclusion

Independent Development of languages has been on the page for a long time. Still, overall development combining the action of Front-end, Backend and database simultaneously has taken the world by storm because of its potential. This has also reduced the financial burden of hiring multiple developers by hiring one MERN Developer.
