MERN Stack Development

Introduction –

The MERN stack comprises MongoDB, Express, React, and Node, representing the key technologies that form this stack.

• MongoDB —    document database
• Express(.js) — Node.js web framework
• React(.js) —     a client-side JavaScript framework
• Node(.js) —     JavaScript web server

MongoDB functions as a document database, while Express.js serves as the web framework for Node.js. React.js is utilized as a client-side JavaScript framework, and Node.js serves as the primary JavaScript web server. Express and Node constitute the middle or application tier. Express.js operates as a server-side web framework, complemented by Node.js, a widely adopted and robust JavaScript server platform. Whether one chooses any variant, ME(RVA)N represents an optimal method for handling JavaScript and JSON seamlessly across the entire development process.

What’s the functioning process behind the MERN stack?

It enables the construction of a three-tier architecture—front end, back end, and database—exclusively utilizing JavaScript and JSON, offering a seamless integration across the layers.

React Js  Front end

At the forefront of the MERN stack lies React.js, a declarative JavaScript framework designed specifically for crafting dynamic client-side applications within HTML. Its core strength lies in simplifying the creation of intricate interfaces by leveraging easily manageable components that connect seamlessly to backend server data, resulting in their smooth rendering as HTML.

Node Js and Express Js 

Node.js functions as an open-source, cross-platform runtime environment, enabling the execution of JavaScript code beyond the confines of a web browser. It’s essential to clarify that Node.js isn’t a framework or a programming language, Its primary use lies in constructing backend services like APIs for web or mobile applications.

Express, a lightweight framework, builds upon Node.js’s web server capabilities. It simplifies APIs, enhances functionality, and organizes applications using middleware and routing.

MongoDB Database tier

 MongoDB stands as an open-source NoSQL database management system, offering an alternative to conventional relational databases through its NoSQL (Not only SQL) approach. This database type is particularly beneficial for handling extensive distributed datasets. MongoDB specializes in managing document-oriented information, enabling the storage and retrieval of data efficiently.

Does MERN encompass a full-stack solution?

Absolutely. MERN embodies a complete solution structured around the traditional three-tier architectural pattern, encompassing the front-end display tier (React.js), the application tier (Express.js and Node.js), and the database tier (MongoDB).

Why opt for the MERN stack?

Let’s begin with MongoDB, the core document database powering the MERN architecture. MongoDB was purpose-built to efficiently handle JSON data (utilizing BSON, a binary version of JSON), and its entire framework, from command-line functionalities to its query language (MQL or MongoDB Query Language), revolves around the principles of JSON and JavaScript.

Express.js (running on Node.js) and React.js complete the JavaScript/JSON application, making the MERN stack comprehensive. Express.js functions as a server-side application framework that encapsulates HTTP requests and responses while simplifying URL mapping to server-side functions. On the other hand, React.js is a front-end JavaScript framework facilitating the creation of dynamic user interfaces in HTML and establishing communication with remote servers.
