The web application development scenario of the twenty-first century is vastly different from that of a few years ago. Previously, you develop mobile and web apps using coding languages such as HTML, CSS, and JavaScript. Today, we have multiple industry-tested server-side technologies, development frameworks, and runtime environments at our disposal. One such technology is the MERN stack. So, previously if you have your preferred technological stack, it’s the best time to switch to MERN. In order to learn about this technology, we suggest you enroll in the MERN Training. Such training will help you move forward in your career and make you understand that it has vast growth ahead.
MERN Stack: Meaning
MERN is an abbreviation for MongoDB, Express.JS, ReactJS, and Node. It is an open-source framework that you can use to create dynamic websites and mobile apps. In other words, MERN is a collection of four prominent technologies. The MERN stack enables modern businesses to develop and deploy robust applications. However, MERN uses JavaScript to facilitate and accelerate full-stack web app development. Moreover, this full-stack JavaScript framework includes,
- Libraries
- Frameworks
- Databases
MERN Stack Components
MERN Stack involves four key components, which are as follows:
● React
Meta or Facebook created ReactJS, a front-end JavaScript library, for their own use. It is also known as React, and you can use it to create dynamic single-page web apps. However, the primary goal of React is to improve app speed and performance. Thus, it has the following characteristics:
- Nested components
- One-way data binding
- Reactive data flow in a single direction
- Virtual document object model (DOM)
● MongoDB
MongoDB is the most widely used non-structured query language (NoSQL) database. It stores dynamic data in a binary version of JSON known as BSON (Binary JavaScript Object Notation). However, MongoDB allows you to run multiple databases at the same time.
● Node JS
Node.js is an excellent web server, or you can say it is JavaScript outside of a browser. However, developers primarily use it to create backend API services and traditional web and mobile apps. Also, Node.js is available on multiple platforms, including Mac OS X, Linux, Unix, and Windows. Thus, it has the following features:
- Free ASCII text file pattern
- Dynamic webpages
- Asynchronous, event-driven model
- Node package manager (NPM)
● Express JS
Express.js is a lightweight version of the Node.js framework. However, programmers can use it to create mobile apps, backends, and moderately complex websites. Moreover, Express.js is a robust, asynchronous, and fast framework. It also includes the following features:
- Single-page and multi-page web applications
- Content bargaining
- HTTP methods Put, Get, Delete, or Post
Use Cases of MERN Stack
The MERN stack helps to improve the overall performance of any application. It will be especially beneficial for managing large and complex projects. However, it is better suited for the development of mobile applications. Here are some MERN use cases:
● Apps for expense tracking
The MERN stack will allow you to create data-intensive expense tracker apps. It will assist users in keeping track of their day-to-day expenses. With this JavaScript framework, you can include data visualization features such as:
- Keep track of your everyday costs.
- Control your tax deductions.
- Keep track of your sales and receipts.
- Actual vs. budgeted spending
● Remote learning applications
Another usage is the development of web-based educational programs. However, the COVID-19 pandemic is a tipping point to embrace an era of remote learning. As a result, MERN-based online classroom applications can have the following features:
- Track the development of your students.
- Upload lectures with chapters
- Share documents via in-app messaging
● Media Streaming applications
One of the uses of MERN is the creation of interactive social media forums. You may use this JavaScript framework to develop a social networking page that has the following features:
- Online Advertisements
- Accumulated Web News
- Commenting and Liking
Conclusion
Hopefully, you may find this article informative. We have compiled the different components and use cases of the MERN Stack. By looking at this overview, if you desire to have a career in this domain, we suggest you enroll in the MERN Online Course.
