5 Things You Need To Know About MERN Stack Development

Summary: Full-stack web application is in demand. The advent of new tech stack combinations and the urge to get a business digitally is growing parallel to it. MERN is one of the widely used tech stacks today in the web app development industry. The technology is used for faster & robust app deployment. Let’s check out some facts about MERN stack development services that will help in application development.

Necessity is the mother of invention- An old proverb that fits well into web app development. With the increasing requirement of consumers, there is an equal exemplary change in web development. The developers, too, are working hard with their full efficacy to provide a great website with a better user experience, less loading time, and mobile-friendliness.

The popular technologies for developing web application is HTML, CSS, & Javascript. But these cornerstones need to provide the above requirements. To fulfill the void, two new tech stacks, MERN and MEAN came into existence. They have become the favorites of web developers to develop incredible websites in no time. This blog explicitly discusses the MERN stack to better understand how well it will work for your development.

What is MERN Stack Web Development?

MERN combines MongoDB, Express JS, React JS, & Node JS. A perfect mixture that develops scalable web apps across the internet. The Javascript framework provides dynamic, responsive, and attractive websites. The stack is mostly used to create sophisticated online applications. This framework is open-source and well-known for supporting full-stack development.

Components of MERN Stack

The 4 pioneers of the stack are as follows:-

MongoDB:

MongoDB is a non-relational database that stores data in binary JSON-like documents. It contains cross-platform features that help in the quicker exchange of data. The web app can instantly run on multiple servers without any event of hardware system failure. The main features of this component are as follows:-

• It provides a document-oriented storage
• It has a single master with built-in replication support
• MongoDB has drivers for every language 
• It provides horizontal scalability to increase the balance of modern apps

ExpressJS:

A server-side backend framework that helps single-page, multi-page, & hybrid web apps. It helps to design faster and more secure applications with minimal architecture. ExpressJS develops a complex web app in no time. In its other known features:-

• It helps make NodeJS web app development faster & easier
• The framework is easy to configure & customize
• It consists of two templating engines, Jade and EJS, to manage the flow of data in a website
• Creates a REST API server
• Easy to connect with databases like MongoDB

ReactJS:

To avail faster and more interactive user interface, one needs the popular Javascript library-ReactJS. MERN stack developers have expertise in using the same Javascript code on multiple platforms. The application built using this framework is fast and highly scalable. In other features, it consists of the following:-

• It uses virtual DOM, which compares the component of the previous state and updates only the changed items in Real DOM
• A developer is allowed to build an app from several tools & libraries present in ReactJS
• The code is easily used on browsers and servers. So, one can create pages on the server wherever they want
• A user can create his component and use it several times in different apps

NodeJS:

It is an open-source and cross-platform framework that allows running outside server codes without any problem on a server. Based on Google Chrome’s V8 Javascript engine, the open-source, scalable network application works without an enclosed HTML page.

• It puts together multiple Javascript files
• It executes Javascript code outside of a browser
• Uses module system based on Common JS

Why should you choose MERN Stack Development Services?

As a Javascript framework, the MERN stack provides a user with both sides of the code- client and server. Switching between tiers is not required because they all use the same language. The many programming languages in a tech stack need to be connected. Therefore developers must work this out. A developer has to be familiar with JavaScript and JSON to succeed in app development. 

You can also approach a MERN stack development company if you have less experience understanding this tech stack. Such firms are way ahead in nurturing your application in the right direction with the correct technical assistance. A wise decision at the right time will help you ace the digital world with MERN.

Benefits of MERN App Development

• MVC architecture: The model view controller pattern divides an application into these three components. It helps a developer in managing specific development aspects. Thus, it helps in convenient app development for the MERN developer community.
• Open-source technology: MERN boosts developers to develop robust web apps. With its open-source code facility, the technology improves coding efficiency and gives tools for faster development. A developer can also mend the changes easily without any online hindrance. 
• Effective SEO: With MERN, a user can create SEO-friendly websites. It implements a user-friendly interface, content management, and seamless data sharing flow, which helps to maintain and manage overall SEO functionality.
• Code reusability: As every tech stack uses Javascript, it is very easy to reuse the code in the making of new modules of the application. In this way, it saves a developer’s time developing the app.
• Improved security: MERN stack development provides the best security as it has flawless components to make it happen. From MongoDB to NodeJS, every framework functions with utmost security for its features & functionalities in the app.

How do you use MERN Stack?

The MERN architecture builds an app in three tiers- frontend, backend,& database using Javascript & JSON.

React JS for Frontend Development

React helps build complex interfaces with simple components and connects the data to the backend server, leaving them as HTML. It is great for handling data-driven interfaces with simpler coding tactics. A developer can easily build intuitive forms, events, and lists and handle errors with great support. One prepares dynamic client-side applications using ReactJS in HTML.

Server Tier for ExpressJS & NodeJS

ExpressJS server-side framework runs inside a NodeJS server. It gives a web app a minimalistic and opinion-free framework. XML HTTP Requests, GETa, or POSTs from the front end of ReactJS connect to the ExpressJS functions that easily run the app. These functions help modify data in your MongoDB file using the lump.js drivers through callbacks or promises.

MongoDB Database Tier

MongoDB comes with a JSON document made in the respond.js frontend that helps manage app stores data like user profiles, content, comments, etc. can be sent to the state.js server. They can be directly stored in MongoDB for subsequent retrieval if they are legitimate. Again, if you’re building on the cloud, you should have a look at Atlas.

Where is MERN used the best?

MERN is a perfect web stack for a cloud-based project that needs a lot of JSON and dynamic web interfaces. It is used efficiently to make other apps like:-

Apps for calendars and tasks: You can learn much about the MERN stack by working on a straightforward project like a calendar or to-do app. The front end, or interface, of an app, like a calendar or to-do list, can be designed with ReactJS. The to-do app can save, access, modify, and display data thanks to MongoDB.

Forums with users: Another effective application for MERN is a social media platform, interactive forum, or website that enables message sharing and interactivity. The forum’s topic may or may not be predetermined in advance.

Social media: The MERN stack can be used to build an interactive forum as one social media application. These include postings, advertisements, a mini-web app integrated into the social networking page, etc.
