What is the MERN Stack?

MERN Stack is specially designed to make website development easy. The MERN Stack segment into four modules MongoDB, Express, React & Node JS. And these modules are the combination of technologies used to create a website application. It becomes more manageable this way as these components are a blend of the libraries, databases, frameworks, etc.

In short, MERN Stack is a JavaScript stack which is a developer to make web development an easy task. These frameworks provide end-to-end frameworks for web applications. 

Now that we know what exactly MERN Stack is let us now study the components in detail.

1. MongoDB:

MongoDB is a document-oriented, shared database, and an efficient, built for radical website application developers. Hence, this makes it more productive and responsive. It is a non-relational (no SQL) document-based database. And because of no SQL, it has no schema design with tables & columns like a relational database. All the data used in MongoDB is stored in a document form with JSON i.e., JavaScript Object Notation based query language. The content, volume, and the number of fields in the documents can differ from one to the next. This means that the data structure to be changed over time. MongoDB is best known for being adaptable and easy to estimate.

2. Express:

Express is a manageable & controlled Node JS website application framework that executes a tough set of traits for website & mobile applications. Express is a MERN Stack module used as a website application framework for Node JS. Rather than writing the webserver code by hand on Node JS, the developers can make use of Express by writing server code and quickly build their tasks. You never have to repeat the same code again and again because of the Node JS HTTP module.

The Express framework is designed for building robust mobile applications, website applications, and APIs. It is renowned for its speed and simple configuration, with many structures available as plugins.

3. React:

React is used for creating interactive User-Interfaces using JavaScript libraries. React was initially created by a software engineer at Facebook, & was later open-sourced. It is managed by Facebook & a community of development companies and individual developers. These libraries are used for creating views provided in HTML in a declarative form. Hence, there is no question of stressing out yourself while developing a website application. React makes use of a full-featured programming language (JavaScript) to construct repetitive or conditional DOM elements. Here, you can make use of the same code to execute on a server as well as the browser.

React holds the MERN Stack, meaning it is the only feature component that makes it different from MEAN Stack.

4. Node JS:

Node JS was first developed for Google Chrome & later converted to be an open-source framework by Google Itself. It is built on Chrome’s V8 JavaScript engine & designed to build scalable web applications. It can perform JavaScript code outside of a browser too.

Node JS mechanisms without an enfolding HTML page, instead of using its module system based on Common JS, to put together several JavaScript libraries.
