React offers you the freedom to pick tools, libraries, and architecture for developing web applications, whereas Angular gives you less freedom and flexibility to build the applications.

If you are techno-friendly, you know that a stack is nothing but an amalgamation of frameworks, coding languages, tools, and libraries that developers use to create robust web applications.

Mern-Stack uses four components to create effective web applications. These are:

1. MongoDB

MongoDB is an open-source document database that can store data of large volumes with scalability. Moreover, it can run over different servers, ensuring quick data integration within web applications.

Key features

  • MongoDB is well known for its flexible and scalable features.

  • It uses native applications to manage multiple copies of the database.

  • The data Is stored flexibly with JSON (Javascript Object Notation) base query language.

2. ExpressJS

ExpressJSis a minimalist and lightweight framework that developers use to build up back-end web applications. It runs on top of the NodeJS, maintaining the server and its routes.

Key features

  • ExpressJS simplifies server code writing, and developers don't need to write the same code repeatedly.

  • It is well known for its fast speed and minimal architecture.

  • Express is used to create single-page, multi-page, and hybrid web applications.

3. ReactJS

ReactJS is an open-source Javascript library that is used to create front-end web applications. It facilitates the way for developers to use a single code base on multiple platforms. Moreover, ReactJS offers tools to build scintillating user interfaces that enhance the quality of front-end web pages.

Key features

  • React follows a one-way data-binding protocol that means the data flows in one direction throughout the application, giving control over it.

  • It boosts the productivity of web app development and ensures faster rendering.

  • React has vast community support as well that enables connectivity amongst developers.

4. NodeJS

NodeJS is an open-source platform that is considered to be a Javascript runtime environment. It deploys the code outside the browser, on the back-end side.

Key features

  • NodeJS library executes quick coding and enhances scalability.

  • It is easy to use and paves the way for ExpressJS to work efficiently.

  • It assists you on both sides i.e. server-side and client-side as the single code runs along with the whole application.

Advantages of the Mern Stack Development

Mern stack development provides several benefits in which Javascript language is the most awesome one. Javascript is the language that is used for both web page development, i.e., front-end and back-end.

Thus, it eliminates the need for content switching, enabling the developers to build applications in less time and effort. On the other hand, the technology stack that deals with multiple languages create problems for developers to build efficient applications.

  • Developers need only to be acquainted with the use of the Javascript language and JSON.

  • The four components mentioned above of the Mern stack are well enough to create efficient web applications.

  • Mern stack offers the MVC(Model view controller) architecture to ensure the smooth flow of the web applications.

  • It allows developers to complete the development cycle from the front-end to back-end pages of the web apps.

  • The most beneficial feature of the Mern stack is cost-effective as it provides all development tools that ensure a full stack developer can create web applications. Hence, a client does not need to hire different developers to work on multiple aspects of the pages.

  • All the four components (ReactJS, ExpressJS, NodeJS, MongoDB) go smoothly with cloud integration.
