MERN is JavaScript technology that makes an enterprise agile. The four technologies that the acronym MERN stack is comprised of are MongoDB, Express, React, and Node.

In simple words, the MERN stack can be defined as a collection of powerful inventions which support flexible expert software, online, and mobile applications.

How Does the Mern Stack Function?

The MERN stack architecture is as shown below. From the figure, we can see that it is a full-stack architecture that comprises a database, a front-end, and a back-end.

The main advantage of MERN is that it only requires knowledge of one programming language and the JSON document structure because the entire project can be completed with JavaScript and JSON.

Let us break it down into its constituent parts:

MongoDB: If your application does any sort of data save, then you’ll need a database for it. Like a social media app that keeps a record of user profiles, content, likes, comments, etc. Although there are other databases, MERN makes use of MongoDB.

  • Cloud-ready
  • Open source
  • Easy to use
  • High performance
  • Scalability
  • Flexible data model

Express.js: This is a simple, flexible Node.js web application framework. Express makes the job of managing HTTP requests and answers as well as forwarding URLs much easier.

  •       Easy APIs
  •       Templating engines
  •       Database integration
  •       HTTP management
  •       Large community
  •       Customizability
  •       Boosts productivity

React.js: An open-source, JavaScript front-end library is an open-source JavaScript library. Meaning to this term, it means it is being maintained by the community of developers and businesses alongside Facebook, now Meta. In React, we can construct our user interface by using the data available in our back-end to create it as HTML.

  •       Popular Companies are Using it
  •       JSX.s
  •       Syntax on server
  •       Huge community
  •       Flexible 
  •       Component can be reused
  •       Performance will also enhance

Node.js: Node.js is an event-driven, asynchronous JavaScript runtime designed for building scalable applications on the network. Node.js can handle multitudes of connections simultaneously, and it will consume relatively limited system resources if no work actually needs to be done. Think of auto-scally apps that increase their CPU and RAM because they need more processing strength to handle a larger volume of requests and less when the quantity of requests declines.

  • Versatility
  • Cross-platform
  • Active community
  • Vast ecosystem
  • Non-blocking I/O
  • Calability

Is Mern Stack Highly in Demand?

The primary reason MERN stack has gained much more popularity recently is that it uses the most popular technologies on offer. Besides, you do not need to switch between front-end and back-end environments. So, as a developer, you need only to know JavaScript and JSON. This will save you time and enable you to finish a project much more quickly. In terms of code reuse or high performance, the MERN stack is also more flexible and user-friendly. Mern stack developers are also in high demand. The Mern Stack developer salary on average in Pakistan is PKR 81,667 per month.

 Can We Call Mern Front-end or Back-end?

In a nutshell: both. The MERN stack makes it possible to design the algorithmic and analytical part of the back-end and the design, UX, and animation part of the front-end.

The business finally benefits from this because hiring cost is reduced as only one MERN stack developer is required to do the job.

Advantages of Mern Stack

Well known companies and brands such as UberEats, Netflix, Facebook, and Airbnb are utilizing MERN in their technological systems. Among the benefits that they receive is as follows:‍

  • Saves time
  • Cost-efficient
  • Market hour to kick off is reduced
  • Customer support
  • Accessible for engineers
  • Seamless user experience

Conclusion

MERN is a technological stack for web application development that is based on JavaScript. Professional developers frequently use it due to its scalability, efficiency, and total reliance on JavaScript.

After viewing the discussion above, it can be concluded that Mern Stack development is in good demand. This has given a rise of the demand of Mern stack developers.

FAQs:

1. What is the MERN stack?

The MERN stack is a collection of four powerful JavaScript technologies: MongoDB, Express.js, React.js, and Node.js. It is used to develop full-stack applications, encompassing both the front-end and back-end, all using JavaScript.

2. What are the components of the MERN stack?

The four components of the MERN stack are:

  • MongoDB: A NoSQL database for storing application data.
  • Express.js: A web application framework for Node.js to manage HTTP requests.
  • React.js: A front-end library for building user interfaces.
  • Node.js: A JavaScript runtime environment used for building back-end services.

3. Why is the MERN stack popular?

MERN stack is popular because it uses JavaScript for both the front-end and back-end, making it easier to develop full-stack applications. It is flexible, scalable, and reduces the need to switch between different programming languages, which speeds up the development process.

4. What are the advantages of using the MERN stack?

  • Saves Time: Developers can work with a single programming language, JavaScript, throughout the entire application.
  • Cost-Efficient: Hiring a single developer to manage both the front-end and back-end reduces costs.
  • Scalability: The stack is highly scalable, making it ideal for growing businesses.
  • High Performance: MERN applications are known for their flexibility and high performance.

5. Is the MERN stack only for web applications?

While the MERN stack is commonly used for web applications, it can also be used to build mobile applications, particularly when using React Native, which is based on React.js.

6. Do I need to know multiple programming languages to work with the MERN stack?

No, the MERN stack allows you to build both the front-end and back-end using JavaScript and JSON, which makes it easier for developers to work on both sides of the application without needing expertise in multiple languages.

7. Is the MERN stack suitable for large-scale applications?Yes, the MERN stack is highly scalable and can handle large-scale applications, such as social media platforms, e-commerce sites, and real-time apps.

8. What kind of developers use the MERN stack?

MERN stack is popular among full-stack developers who are proficient in JavaScript. It is also widely used by developers working on web and mobile applications due to its flexibility and the unified language for both front-end and back-end development.

9. Is MERN stack in demand?

Yes, MERN stack development is in high demand because of its efficiency, scalability, and the ability to complete projects faster. MERN stack developers are highly sought after in the tech industry.

10. Which companies are using the MERN stack?

Several well-known companies like UberEats, Netflix, Facebook, and Airbnb utilize the MERN stack in their technology stacks for building scalable and flexible applications.

11. How does MERN compare to other tech stacks?

Compared to other tech stacks like MEAN (Angular instead of React) or LAMP (Linux, Apache, MySQL, PHP), MERN is more developer-friendly due to the use of JavaScript across the entire stack, simplifying the development process.

12. What are some challenges of using the MERN stack?

While the MERN stack is powerful, it can have challenges such as:

  • Steep learning curve for beginners, especially with MongoDB and React.
  • Handling the asynchronous nature of Node.js can be complex.
  • Requires adequate knowledge of JavaScript for both front-end and back-end development.

13. How does MERN Stack improve developer productivity?

MERN stack improves productivity because developers only need to learn JavaScript and JSON. This uniformity across the stack makes it easier to manage code, share components, and build applications more quickly.

14. Can a single developer handle both front-end and back-end using MERN?

Yes, since the MERN stack uses JavaScript for both the front-end (React.js) and back-end (Node.js/Express.js), a single developer can handle the entire development process, reducing the need for multiple specialists.

15. What is the average salary for MERN stack developers?

The average salary for MERN stack developers varies by region. For example, in Pakistan, the average monthly salary is around PKR 81,667. Salaries may be higher in other countries depending on demand and location.
