Hi Guys, Welcome to Proto Coders Point. In this article, we’ll know about What MERN stack is and how it works!

The MERN Stack stands for MongoDB, Express JS, React JS, Node JS. This is a full tech stack for building scalable web applications. MERN Stack developer is a full-stack developer who works on such technologies. Here’s the MERN stack meaning & full form

M for MongoDB

MongoDB: A NoSQL Database which is differentiated from a traditional relational database

Objects -> Collection -> Documents -> Data

We can use documents instead of designing a database with tables. MongoDB helps us to do this with its document model.

In Mongo, you can store well data structures with subtopics and fields being objects as well. MongoDB takes care of almost all the features. You can literally keep whatever you want into the collection and it’ll store it!

E for Express JS

Express: Web Server. Express, is a back-end web application framework for Node.js. It facilitates the fast development of Node-based Web applications.

Some of the core features of the Express framework −

  • Allows us to set up middlewares to respond to HTTP Requests.
  • Defines routes that are used to perform different actions based on HTTP Method and URL.
  • Allows rendering HTML Pages dynamically based on arguments passed to templates.

R for React JS

React – The front-end JavaScript library for building interactive user interfaces or UI components.

Reactjs designs simple views for each state and will efficiently update and then render the right components when your data switches.

N for Node JS

Node – Base Server. It is a back-end JavaScript Runtime environment that executes JavaScript code outside a web browser.

Integration – Putting it all together

The MERN architecture allows you to easily build an architecture (frontend, backend, database) entirely using JavaScript and JavaScript Object Notation.

Express.js and Node.js make up the middle tier of the application. Express.js is a server-side framework and Node.js is a famous and powerful JavaScript server platform. Regardless of which tech stack you choose, either MERN, MEAN, or MEVN is the ideal approach to working with JavaScript anyway.

Feasibility of four best technologies, i.e. MongoDB, Express JS, React JS, and Node JS.

Most popular tech stack in 2021 which enjoys the support of the biggest community of developers with so much support

Thanks for reading and I hope you learned something, share it with your connections and let them know about such a wonderful tech stack.
