MERN stack is a collection of technologies that enables faster application development. It is used by developers worldwide. The MERN stack’s main purpose is to develop apps using JavaScript only. This is because the four technologies that comprise the technology stack are all JS-based. Thus, if one knows JavaScript (and JSON), the backend, frontend, and database can be operated easily.
MERN Stack Full Form
The beauty of MERN lies in its focus on JavaScript. That’s right, all four technologies in this stack are built around this versatile language:
Why Choose MERN?
There are many good reasons to use the MERN Stack. For example, it allows the creation of a 3-tier architecture that includes frontend, backend, and database using JavaScript and JSON.
MongoDB, which is the base of the MERN stack, is designed to store JSON data natively. Everything in it, including CLI and query language, is built using JSON and JS. The NoSQL database management system works well with NodeJS and thus, allows manipulating, representing, and storing JSON data at every application tier.
It comes in a variant called MongoDB Atlas that further eases database management by offering an auto-scaling MongoDB cluster on any cloud provider with just a few clicks.
Express is a server-side framework that wraps HTTP requests and responses and makes mapping URLs to server-side functions easy. This perfectly complements the ReactJS framework, a front-end JS framework for developing interactive UIs in HTML while communicating with the server.
As the two technologies work with JSON, data flows seamlessly, making it possible to develop fast and debug easily. To make sense of the entire system, you need to understand only one language, i.e., JavaScript and the JSON document structure.
Use Cases of MERN
Like other popular web stacks, it is possible to develop whatever you want in MERN. Nonetheless, it is ideal for cloud-based projects where you require intensive JSON and dynamic web interfaces. A few examples of purposes where MERN is used are:
Calendars and To-do Apps: A calendar or a to-do app is a rudimentary project that can tell you a lot about the mechanics of the MERN stack. You can design the front end, i.e., the interface of the calendar or to-do app using ReactJS. The data to be stored, accessed, modified, and shown in the to-do app is made possible using MongoDB.
Interactive Forums: Another suitable use case for MERN is an interactive forum, which can be a social media platform or a website that allows users to share messages and communicate. The topic of the interactive forum may or may not be predefined.
Social Media Product: An interactive forum is just one use of the MERN stack for social media. These include ads, posts, a mini web app embedded in the social media page, etc.
Conclusion
Contemporary web developers with enough experience in React and JS prefer developing intuitive applications using the MERN stack.
