The Bottom Line

Gone are the days when developers had to rely on multiple technologies scattered across the web world to build a robust web app solution.

Now, MERN has redefined the way web apps are built, it includes MongoDB, Express.js, React.js, and Node.js.

Indeed, this amalgamation vouches for excellence and creativity at its best enabling seamless data and code flow for a remarkable user experience.

To help you understand the nitty-gritty involved in the MERN and what all it involves that is creating a stir in the world of web app development, we have brought you this post…Let’s begin.

What is MERN?

MERN stands for 4 different technologies that work together and help in developing dynamic web apps and websites.

M – MongoDB

E – ExpressJS

R – ReactJS

N – NodeJS

MERN Stack Components

As we have discussed above there are 4 components within the MERN, let’s unleash the power of each below:

MongoDB

As we all know, MongoDB is a NoSQL DBMS that stores data in the form of documents.

These data sets hold key-value pairs similar to JSON objects, letting developers build databases, schemas, and tables effortlessly.

Furthermore, with this developers also get the option to access a Mongo shell which is highly useful for the JS interface and extensively used for deleting, querying, and updating the records.

ExpressJS

Backend developers have dealt with the challenges of simplified backend code and often face trouble while doing so.

To ease down the woes ExpressJS comes to the rescue, it is a NodeJS framework that simplifies writing the backend code.

Using this, developers can create multiple Node modules and it does not stop here, but to keep the code precise, developers can use ExpressJS which comes packed with a wide range of middleware.

ReactJS

In the developer fraternity, everyone is well versed in the benefits ReactJS brings to the table, and in the MERN it is one of the components that opens a glut of benefits.

It is a JS library enabling developers to soak their feet into the innovative user interface development for mobile apps and SPAs.

Leveraging this technology, developers can code JavaScript and make UI components clutter-free.

Here, the integration of the virtual DOM into the JS library ensures a seamless development journey.

NodeJS

To be precise, NodeJS is an open-source JavaScript runtime environment.

It is used by the developers to run code on the server and comes packed with the node package manager or npm.

With this technology, developers can easily select from the available wide range of node modules or packages.

Since NodeJS is developed on the Chrome JavaScript Engine it ensures coding execution is faster, smoother, and seamless.

Compelling reasons to use MERN

Often, it is being asked why we should use MERN when there are other options available in the market.

So the first and foremost reason is to understand the basic 3-tier architecture required to build a web app consisting of frontend, backend, and database using JavaScript and JSON.

MERN addresses this architectural demand under one roof with:

MongoDB, one of the base components of the MERN stack, is designed to store JSON data natively. It includes CLI and query language which is built using JSON and JS. On the other side, the NoSQL DBMS aligns with NodeJS enabling it to manipulate, represent, and store JSON data at every tier of the Full-stack development.
There is a variant of MongoDB – MongoDB Atlas which helps in smoothing down the database management by offering an auto-scaling MongoDB cluster on any cloud and this can be done with just a few taps.
Express being a server-side framework includes HTTP requests and responses while ensuring to map URLs to server-side functions seamlessly. It further fits the demand of the ReactJS framework to build interactive UIs in HTML while communicating with the server.
MERN as a whole helps to build web app solutions fast and debug easily and to make this work developers do not require a bunch of technologies, but only one language, i.e., JavaScript and the JSON document structure.

Tips to bring efficiency as a MERN Stack developer

MERN stack is a combination of innovative technologies, hence it is highly valuable to stay alerted about what is going on in there. Developers must attend conferences, join community groups, and read to stay informed.
MERN is based on the JavaScript language, thus, it is highly recommended to learn and explore every bit of JavaScript fundamentals. This helps to ease down the process of learning and implementing the MERN stack in the projects without facing any challenges.
It is noteworthy to get equipped with the revolutionary library- React.js, which is embraced by tech giants across the world. There is always a hustle in this library as it is constantly updating and evolving at a rapid scale, so stay informed to gain a learning edge.
It is always a good choice to invest time in new technology and nothing fits the bill here rather than contributing to the open-source projects which involve the MERN stack. With such projects, developers can get hands-on practice on live projects and get the experience and skills required to build a scalable web app solution.
Gain intensive information about Express.js which is a huge hit among the startups for MVP. On the other side, invest time in learning and exploring more about MongoDB. The tutorials and learning activities can be availed through online resources or courses.
Always stay alert on the learning curve and strive hard to learn and explore continuously. Be ready to embrace new ideas and technologies to acquire skills that can help you stand tall and bright in the ever-flourishing competitive world.
Get involved with the MERN community to get assistance as and when required. There are a whole bunch of MERN developers with skills at par excellence to help you sail ahead.

The Bottom Line

The future for MERN is bright and promising, however, the only need of the hour is to stay updated and apply the best of skills and knowledge to build intuitive app solutions.

Businesses, on the other hand, must Hire MERN Stack Developers to open the plethora of opportunities and possibilities in their web app solution using MERN stack.
