MERN Stack: A Detailed Beginner’s Guide 2024

MERN stack is a set of technologies that allows for speedier application development. It is used by developers worldwide and, mastering it is quite straightforward.

What is MERN Stack?

Like most of the tech stacks, the name "MERN" is an acronym representing its core technologies. The MERN stack, tailored for web development, comprises MongoDB, Express, React, and Node.js. There are also other stacks in the family such as MEAN (MongoDB, Express, Angular, Node) and MEVN (MongoDB, Express, Vue, Node). Think of it as the complete set of tools for full stack developers. 

Now, let’s break down each component of MERN.

  • MongoDB – The database component. MongoDB is a non-relational (NoSQL) database management system (DMS). There are several reasons why MongoDB is a tool of choice for many full stack developers. It is especially valued for its fast responses, high scalability, simplicity, and flexibility. 
  • Express.js – The server-side web framework for the back-end, layered on top of Node.js. It simplifies writing back-end code by keeping it precise and allowing usage of middleware. It is popular in the full stack development community for its efficiency, speed, and scalability.
  • React.js– React is a library originally built by Meta. It’s used to modularize code and build reusable UI components for the frontend’s user interface.
  • Node.js– Node is an open-sourced JavaScript runtime environment. Its major role is allowing JavaScript to run outside the web browser by converting it into code the server can read. Quick code execution and high scalability make it a top choice among developers.

What the MERN stack is used for?

The MERN stack is used to create web applications that demand a strong back-end logic, dynamic front-end interfaces, and efficient data store and retrieval mechanisms. It allows developers to create full-stack apps exclusively in JavaScript, speeding the development process and increasing code reuse and maintainability.

Why use the MERN stack?

MERN stack is simple, fast, and versatile. Here’s why web developers and software engineers prefer this tech stack.

  • JavaScript-only: No need for specialized developers
  • Faster ramp-up time
  • Ideal for modern web apps JSON-rich, cloud-native, dynamic interfaces
  • Easy scaling
  • All open-source, continually updated
  • Large community support

Learning the MERN stack as a fresher is advantageous for several reasons:

1. Full-Stack Development Capability: The MERN stack enables you to build complete web applications, covering both front-end and back-end development.

2. High Demand in the Job Market: Startups and MNCs alike prefer the MERN stack due to its efficiency and performance. Learning it can enhance your employability.

3. Real-World Applications:
Many leading tech companies, including Facebook, Netflix, and Airbnb, use components of the MERN stack. As a fresher, building projects with the MERN stack can create impressive portfolio that showcase your ability to develop robust web applications.

4. Educational Value:
Working with a full-stack technology improves your problem-solving skills and understanding of how different parts of a web application interact.
