The web and app development industry has gone a far level ahead as what it was earlier. Developing a web app provides tonnes of unique and creative web designs to work on. They are all built utilizing 'tech stack' comprising of robust and scalable technologies that are ruling the web development industry nowadays.

For businesses to ensure fast web development and high-level efficiency must have to choose the right tech stack to deliver inevitable web experience to the users. Wondering how? Let's check out!

What is the MERN stack?

MERN stack is a collection of robust and powerful technologies used to develop scalable master web applications, comprising front-end, back-end, and database components.

The set of incredible technologies it includes are Mongo DB, Express, React  JS, and Node.js.

MongoDB: A document database that is used mainly by the back end application to store its data as JSON documents.

Express: A back end web application framework that runs applications on Node.js

React: A JavaScript front-end library for interactive front-end development

Node.js: A JavaScript runtime environment that lets you run your application back end in JavaScript

MERN Stack Components- A Closer Look

Let's have a sneak peek into the MERN stack components which makes web development all the way easier to do.

MongoDB: A cross-platform document database

MongoDB is a document database in which data is stored in flexible documents with a JSON (JavaScript Object Notation) based query language. The content, size, and number of fields in the documents can differ from one another which means that the data structure can be changed over time. MongoDB framework is best known for its flexible and scalable features. Check out some use cases of MongoDB here.

Why use MongoDB?

  • It makes all the way easy to index documents

  • Ensure scalability as large data can be handled easily by dividing it into several machines

  • Schema Less as any type of data stored in a separate document

  • It’s really simple to set up a MongoDB environment

  • It supports flexible document-model which is fast to create 

Express: A back-end web application framework

Express is a web application framework for Node.js. The framework simplifies the task of writing server code. For developers, there is no need to repeat the same code, as did earlier with the Node.js HTTP module.

The express framework is designed to build robust and scalable web applications and APIs. It is popularly known for its fast speed and minimal architecture.

Why use Express?

  • Asynchronous and Single-threaded.

  • It is fast and scalable

  • It helps with code reusability using built-in router.

  • Robust API

React: Library for building User interfaces

React was developed by Facebook developers. The library is used for developing views in HTML. Instead of using templates to automate the creation of repetitive HTML elements, React uses a comprehensive programming language to built repetitive DOM elements. With this, we can run the same code on both the server and the browser. It completely differentiates MERN from MEAN.

Why use React?

  • ReactJS supports Components that are basically building blocks of UI where each component has a logic. The components also support code reusability and make the web application easier to develop and understand.

  • Features like Virtual DOM, JSX, and Components make it much faster than the other frameworks.

  • React Native can easily code for Android and IOS apps using JavaScript and ReactJS.

Node.js: A JavaScript runtime environment

Node.js is built on Google Chrome and open-sourced by Google. The framework is built on Chrome’s JavaScript engine. It is designed to develop scalable network applications and also to execute JavaScript code outside of a browser. It works great when enclosed with HTML page instead of using its module.

Why use Node.JS?

  • It supports open-source JavaScript Runtime Environment

  • It has a single-threaded model

  • Node.js has a fast code execution as it is built on Google Chrome’s JavaScript Engine

  • It is highly scalable

Advantages of MERN stack:

MERN is the most popular stack after MEAN. Here are some of the advantages of using MERN stack:

  • It includes the entire web development cycle from front-end development to back end development

  • It facilitates the MVC (Model View Controller) architecture that make the web development process work smoothly

  • MERN is considered a cost-effective stack as with open-source support, accessible set-up and reduced learning time, it may have the lowest development cost

  • With the JavaScript stack, developers only need to be proficient in JavaScript and JSON

  • The four robust technologies are feasible enough to develop a full-fledged software

  • The framework comes with a pre-built extensive suite of testing tools

  • MERN framework helps to build flexible and scalable websites

  • The four technologies provide smooth integration with cloud platforms

 Why should Startups hire a MERN developer?

  • The entire web development cycle from front end to back end development using JavaScript come under this

  • Facilitates the MVC (Model View Controller) architecture to make the development process flow smoothly

  • MERN developers only need to be proficient in JavaScript and JSON

  • Facilitates with pre-built testing tools

  • Open-source framework and backed by good community support

Key Takeaways

  •  JavaScript supports businesses with high-quality performance and scalability that helps them boost their revenues

  • The robust technologies empower new-aged developers to develop websites with a seamless experience that give users a sense of fullfillment

  • Assist in creating new ideas that can help develop a master product with unique features

  • It diminishes the necessity for context change

Why did Startups choose the MERN stack for development over MEAN?

We already went through all the core components of the MERN stack. Each component has some of the other unique and useful features to offer and it directly affects a Startup agile development process.

Great community:

MERN has built a great community behind it. The reason behind its great community is JavaScript. As a Startup owner, you can always access tons of resources related to MERN or its components. Each one of the components is well-documented and provides scalable solutions. With this, Startups are free-to-play with their ideas.

Full Stack:

MERN offers a full-stack development environment which leads to end-to-end development. With this, Startups do not have to worry about other technologies or tools as they get everything in the stack itself.

MVC Architecture Support:

MERN supports Model View Controller architecture, which makes it easy for developers to develop workflow.

Low learning curve:

MERN is easy to learn and implement. The learning curve becomes easier if the developer is already familiar with JavaScript. The availability of proper tutorials, documentation, and community support also helps new learners in pursuit of expertise.

Pool Of Talent available:

A Startup needs good talent to bring their ideas to real-life. MERN is popular among developers due to JavaScript affiliation. In short, Startups will find no problem finding the talent for their projects.

Open Source:

All the four components are open source, which means that a Startup does not have to worry about licensing problems with MERN.

Testing tools:

MERN comes with its own set of the testing tools suite. So it’s easy for new developers to test the software with the testing tools provided within the framework

Last words

This leads us to the end of our article, where we briefly discussed MERN and then shifted our focus on the benefits and popularity of MERN. All these factors are more than enough to make MERN a viable technology candidate for any startup. Your startup is unique and it requires a solid suite of skills that fulfill your startup's development needs. A smart decision of hiring a full stack developer gives you and your business lucrative opportunities to work with latest talent skills and also to boost revenues.
