Why is MERN Stack Popular for Web Application Development?

Companies require a combination of technologies to build and run an application smoothly. This combination of technologies in use is called a technology stack. It can be assumed that without these stacks, it is impossible for any company to complete a web application development project successfully. These technology stacks generally comprise of libraries, frameworks, languages, databases, front- and back-end tools, etc.to build a project.

MERN which stands for MongoDB, Express, React, and Node, is an essential technology stack in full stack development. Technology stacks help different companies fulfill their project requirements according to their product roadmap. 

The primary objective of MERN stack development is to help companies deal with difficult projects with the help of JavaScript-based tools. It helps achieve accuracy in the projects with the help of programming languages and with the coordination between the frontend backend development processes.

A MERN stack developer is adept at using all tools and technologies to build stunning applications. 

Web Application Development: Principles, Concepts, and Methodologies

Web application development deals with building applications that exist on remote servers and are rendered on clients’ (or end-users) browsers or devices. Mostly, it is not necessary to download web applications as they can be accessed from browsers such as Google Chrome or Safari.


A web application is stored on a remote server as a program and is delivered over the internet browser interface. Web applications can be used and designed for various uses and – can be utilized by companies or individuals. Web applications may  also provide subscription-based services.

Web application development is an important aspect for companies nowadays as it helps them to propagate information and spread awareness  through various browsers over the internet. Sincethe internet is used by many people, it is easy for companies to make their projects known to the public through web application development.


It is important to follow certain rules and guidelines while developing a web application. These guidelines help the right process of web application development . 
These principles can be stated as follows:

1. Multiple deployments can be accommodated by one code-base during the process or cycle of web development.

2. Explicitly declare and isolate dependencies such as external libraries and services that have been used for the software.

3. All the various types of services that run on your web have to stay detached.

4. Each software development stage has to be built and run separately.

5. Make processes that can store the data and information outside the web application.

6. Use port binding to export services and keep the software self-contained.

7. The fast launching and shutting down process should be applied to make the application more sustainable.

8. Keep the development and production stages of the application similar and intertwined with each other.

9. Manage the admin activities as a separate department from the web application development process.

Therefore, these are the principle guidelines that should be kept in mind whenever anybody is  developing a web application.


Various companies or individual developers opt for a variety  of methodologies so that it is easier  for them to develop a web application that the public can understand and for any company to use and accommodate in their project.
