MongoDB stores data as JSON-like documents. Mongoose ORM (Object-Relational Mapping) . It allows easy integration with Node.js.

Get In-depth Knowledge of MongoDB with the following self-paced course.

2. ExpressJS

Express is a lightweight framework that enables web application development. This allows you to handle only HTTP requests and responses, and manage sessions and authentication with some middleware modules.

3. ReactJS

React is a library written in Javascript for building the front end of applications. In ReactJs programmers can build reusable elements and Manage application state efficiently. Also, React supports server-side rendering, which allows developers to improve performance and increase the SEO of their applications.

Get In-depth Knowledge of ReactJS with the following self-paced course.

4. NodeJS

Node.js is a JavaScript runtime environment that provides developers with a platform to run code written in JavaScript outside of the browser. Additionally, Node.js builds server-side applications on top of his MERN stack with many built-in modules for file I/O, networking, and security.

Benefits of Learning MERN Stack

  • JavaScript can be used to build front-ends and back-ends.
  • Integrating JavaScript reduces the time and money spent learning other programming languages.
  • MERN Stack is a quick, easy, and low-cost.
  • The Mern stack libraries and tools are sufficient to build complete software applications. MongoDB, a library, uses the JSON (JavaScript Object Notation) language to manage and store data. This format is now widely used for encoding and decoding full-stack applications that are transferred between clients and servers, and vice versa.
  • The Mern stack is based on MVC architecture.
    1. Model - MongoDB performs database-related tasks.
    2. Views - UI for React Design frontends or applications.
    3. Controller – ExpressJS backend manages the logic.
  • Its modules and functions are highly adaptable.
  • Scalability: You can scale MongoDB horizontally by adding servers.

Advantages of Mern Stack

1. MVC

  • MERN stack is easy to understand because it has a simple Model-View-Controller structure.
  • Another important advantage is that MERN applications are designed to be shared using micro-services, where each service works independently. T
  • MERN is ideal for creating reliable programs.

2. Full-Stack

  • MERN Stack tools make it easier for programmers to write programs fast and with less effort.
  • With  API calls, Programmers can focus more on solving problems, adding new features, and improving the product.

3. Easy Learning technology

  • It is a combination of a programming language, a framework, and a runtime system.
  • MERN is a programming language that works on the online also as well as offline.

4. Maintenance

  • With the MERN stack, programmers can build software that is easier to handle as compared to other traditional web applications.
  • The MERN architecture has multiple tiers, making it scalable and maintainable.
  • This way of building applications not only saves time but also proves to be a cost-effective solution.

5. Flexibility

  •  MERN  allows the components of the tech stack to be open source while avoiding license problems.
  • It is especially good for software that needs a clear separation of reliable data and business logic.
  • It simplifies the code for the front end, back end, and database separately, And it makes all so much easier.
