Introduction
In the current day and age, MERN stack developers are in great demand due to the popularity of the MERN stack. A compelling technology, the MERN stack is widely used for building web applications.
Companies of all sizes and industries require web developers equipped with MERN stack skills to develop and maintain their web applications. Moreover, the job of a MERN stack developer is well-paying, and they can earn even more with the right skills and experience.
What Is a MERN Stack Developer?
A MERN stack developer is a web developer who is well-versed in implementing specific technologies to create web applications for companies and organizations. The MERN stack consists of four main components:
MongoDB
MongoDB is a NoSQL document database for storing and managing data. It is very scalable and ensures excellent performance. This component uses JavaScript for coding language which is a great advantage. Other features of MongoDB include indexing, replication, etc. You can refer to a MongoDB tutorial to hone your skills.
Express
Express is a web application framework for Node.js used to build web applications' back-end. With the help of Express, single-page, multipage, and hybrid web applications can be built. This component is used to provide server-side logic for mobile and web applications, and is widely used as a result. It is extremely efficient and scalable in nature.
React
Created by software engineer Jordan Walke, React is a JavaScript library that is used to build the front end of web applications. This component is utilized to devise user interfaces, especially for a single page web application. According to a source, nearly 8700 industrialists implement React. Some popular React applications include Netflix, Instagram, Uber, Airbnb, Twitter, Uber, and Reddit. It is easy for a beginner to learn the nuances of React and create web and mobile applications with the help of this front-end framework. React ensures highly fast performance due to the immutability of the data.
NodeJS
MERN stack developers must be well-versed in this technical skill, a JavaScript runtime environment used to build the back-end of web applications. You can utilize NodeJS to devise data streaming applications, JSON APIs-based applications, and Data-Intensive Real-time Applications (DIRT). This component is comparatively easy to master as it uses JavaScript for running codes of web-based projects and multiple web and mobile applications. If you are well-versed with front-end development and possess a good command of JavaScript, you will be able to effectively learn the nuances of NodeJS.
Each of these four technologies of the MERN stack play a significant role in providing an end-to-end framework for web developers. They play a crucial role in the development process of several web applications.
Why Is MERN Stack Used for Web Development?
Here are some reasons why the MERN stack is used for web development:
It is Cost-Effective in Nature
All four technologies that form the MERN stack are built in JavaScript. Consequently, they are cost-effective, and users can get great value for money or output for the amount they pay.
It Is SEO-Friendly
In this case, search engine optimization friendly means that Google, Yahoo, and other search engines can effectively search each page on the website, comprehend and correlate the content easily with searched text and effectively index it in the database. This means websites built using the MERN stack are generally SEO-friendly.
Ensures Fast Delivery
Any web application built with the help of the MERN stack is built very fast, ensuring faster delivery to the clients.
Open Source
All four components of the MERN stack are open-source technologies. As a result, developers can get solutions to their queries effectively.
It Is Easy To Switch Between Client And Server
MERN is very simple and fast as it is written in one language. Moreover, it is also easy to switch between client and server.
