The topic of the interactive forum may or may not be predefined.Īn interactive forum is just one use of the MERN stack for social media. The data to be stored, accessed, modified, shown in the to-do app is made possible using MongoDB.Īnother 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. You can design the frontend, i.e., the interface of the calendar or to-do app using ReactJS. A few examples of purposes where MERN is used are:Ī calendar or a to-do app is a rudimentary project that can tell you a lot about the mechanics of the MERN stack. Nonetheless, it is ideal for cloud-based projects where you require intensive JSON and dynamic web interfaces. Like other popular web stacks, it is possible to develop whatever you want in MERN. To make sense of the entire system, you need to understand only one language, i.e., JavaScript and the JSON document structure.
This perfectly complements the ReactJS framework, a front-end JS framework for developing interactive UIs in HTML while communicating with the server.Īs the two technologies work with JSON, data flows seamlessly, making it possible to develop fast and debug easily. It comes in a variant called MongoDB Atlas that further eases database management by offering an auto-scaling MongoDB cluster on any cloud provider and with just a few clicks.Įxpress is a server-side framework that wraps HTTP requests and responses and makes mapping URLs to server-side functions easy. The NoSQL database management system works well with NodeJS and thus, allows manipulating, representing, and storing JSON data at every tier of the application. Everything in it, including CLI and query language, is built using JSON and JS. MongoDB, which is the base of the MERN stack, is designed to store JSON data natively. For example, it allows the creation of a 3-tier architecture that includes frontend, backend, and database using JavaScript and JSON. There are many good reasons to use the MERN Stack.

Being developed on the Chrome JavaScript Engine enables Node to execute code faster. It comes with the node package manager or npm, enabling users to select from a wide selection of node modules or packages. NodeJS is an open-source JavaScript runtime environment that allows users to run code on the server. The JS library uses virtual DOM for doing everything. It allows you to code JavaScript and develop UI components. ReactJS is a JS library that allows the development of user interfaces for mobile apps and SPAs. For keeping the code precise, ExpressJS offers a range of middleware.
It saves you from creating multiple Node modules. It offers the Mongo shell that provides a JS interface for deleting, querying, and updating the records.ĮxpressJS is a NodeJS framework that simplifies writing the backend code.
MongoDB enables users to create databases, schemas, and tables. MongoDB is a NoSQL DBMS where data is stored in the form of documents having key-value pairs similar to JSON objects. Let’s learn more about these MERN Stack components: It is a JS runtime environment, i.e., it enables running JavaScript code outside the browser. The final component of the MERN stack is NodeJS.The third component is ReactJS, a JavaScript library for developing UIs based on UI components.It is a backend web application framework for NodeJS. The second MERN stack component is ExpressJS.The first component is MongoDB, which is a NoSQL database management system.There are four components of the MERN stack.

Npm install module_name -save MERN Stack Components Next, you need to open the folder on the CMD (or terminal) and enter the following command to initialize a package.json file:Ī standard JSON package looks as shown below:

It is a contraction for four different technologies as mentioned below:Ĭonsidering you’ve downloaded and configured all the four aforementioned technologies, you need to know how to create a new project folder to get started with the MERN stack. MERN Stack is a compilation of four different technologies that work together to develop dynamic web apps and websites. Thus, if one knows JavaScript (and JSON), the backend, frontend, and database can be operated easily. This is because the four technologies that make up the technology stack are all JS-based. The main purpose of using MERN stack is to develop apps using JavaScript only. MERN stack is a collection of technologies that enables faster application development.
