MERN stack is a popular choice for building full-stack web applications, as it allows for a seamless flow of data between the front-end and back-end. It is in high demand these days and makes for a lucrative career option for youngsters. 

So, how do you learn it?

Well, MERN is a collection of technologies that are commonly used together to build web applications - the acronym stands for MongoDB, Express.js, React, and Node.js. If you are a student of computer science engineering, you will probably have an idea about them. But if you are starting out your study in the field of programming, you can take up a Bachelor of Computer Application, or BCA course, to get introduced to these platforms. Once you start exploring a BCA program, you can gradually dive deeper into MERN.

What is MERN Stack?

The MERN is the acronym for four technologies. MERN allows developers to use a single language (JavaScript) throughout the entire development process. As a result, it simplifies the development process and makes it easier for developers to switch between the front-end and back-end of the application.

Components of MERN Stack

  1. MongoDB: MongoDB is a NoSQL database that stores data in a JSON-like format. It is known for its scalability and flexibility and is often used in modern web applications.
  2. Express.js: Express.js is a minimal web application framework that runs on top of Node.js. It is used to handle routing and middleware in the application.
  3. React: React is a JavaScript library for building user interfaces. It was developed and maintained by Facebook and is known for its efficient performance and ability to handle large and complex applications.
  4. Node.js: Node.js is a JavaScript runtime that allows you to run JavaScript on the server side. It is built on Chrome's V8 JavaScript engine and is known for its speed and ability to handle a large number of concurrent connections.

Advantages of Using MERN Stack

The MERN Stack (MongoDB, Express.js, React, Node.js) offers several advantages for web development, including:

  • Full-stack JavaScript development, allowing for a consistent language throughout the stack.
  • A consistent set of tools for development and high scalability and performance.
  • Large and active community for support and resources.
  • High performance and flexibility with MongoDB as a NoSQL Database.
  • React for building dynamic and interactive user interfaces.
  • Node.js for building high-performance server-side applications.
  • Express.js for building the backend and API with minimal effort.

MERN stack is a popular choice for building web applications, and you'll likely find a lot of resources, tutorials, and support for working with these technologies. This makes it easier to find answers to questions and learn new skills. 

Career Opportunities for MERN Stack Developers

A MERN developer's salary can vary depending on factors such as the company, location, and the developer's experience level. The average salary for a Full Stack Developer in India is around ₹6,50,000 per year and it can go up to ₹12,00,000 per year, depending on the company and location.

FAQ - MERN stack

Is MERN stack good for beginners?

The MERN stack (MongoDB, Express.js, React, and Node.js) is a popular development stack that can be a good option for beginners who want to learn web development. Each of the technologies in the stack is widely used and well-documented, making it easier for beginners to find resources and tutorials to learn from.

Is MERN and full stack the same?

No, MERN and full stack are not the same. MERN refers to a stack of technologies that includes MongoDB, Express.js, React, and Node.js, which are used to build web applications. Full stack, on the other hand, refers to a developer who is proficient in all aspects of web development, including both the front-end (client-side) and back-end (server-side) technologies. A full-stack developer may use the MERN stack but also use other technologies such as Angular, Vue.js, or even a different database like MySQL.

Which is better: NodeJS or MERN stack?

Both Node.js and the MERN stack are popular technologies that are in high demand in the job market.

Node.js is a versatile technology that is used in a wide range of applications, from web development to IoT and robotics. Node.js developers are in high demand for building fast and efficient web applications, real-time applications, and APIs. Node.js is also popular in the startup community and is used in many popular web apps and services.

The MERN stack is also a popular choice for building web applications, particularly those that require a MongoDB database and a React front end. The MERN stack combines the power of Node.js with the flexibility of MongoDB, Express.js, and React, making it a popular choice for full-stack web development.
