Do you know what MERN stack is and how it works? What technologies are included in it and is it a full-stack solution? Why should you use it? Want to know the answers, then read this article till the end.
When these technologies are blended to work together, they allow developers to create complex, powerful, and impressive web applications. Their amalgamation is designed to make the development process faster, more efficient, and smoother.
Each of the technologies has a big part to play in developing the most advanced web application software. They provide the possibility to master both the algorithmic and logical aspects of the backend along with UI design, user experience, and animated components of the frontend.
Let’s learn more about what this alliance of the most powerful technologies has to offer:
As mentioned, the first essential component of the MERN stack is MongoDB. So, let’s get to know the goal of this database in the MERN stack.
MongoDB is a NoSQL database that enables developers to manage the databases of web applications. It is used in the MERN stack to record documents of key-value pairs that are similar to JSON. It’s flexible and allows developers to create schema, tables, databases, etc.
Here are a few reasons to use MongoDB
Express is a NodeJS-based framework, which makes it simpler to write codes for the backend of the web application. The framework plays a key role in designing great web applications and APIs for it. Moreover, the ExpressJS framework includes support for many middlewares which makes code short and easier to write.
Here are some reasons to use ExpressJS:
Here are a few reasons to use React in the MERN stack:
Here are a few reasons why NodeJS has made it to the MERN list:
To make things simple, let's divide the MERN stack into two segments: Backend and Frontend. The below diagram shows how this alliance works collaboratively.
As you can see from the diagram, MongoDB, NodeJS, and Express are utilized for developing the backend of web applications. This means these frameworks take care of things like database management, scripts, HTML documentation, HTTP requests, and many other corresponding things.
The React framework's role here is simple and it is to execute HTTP requests. Developers can make Ajax calls, which allows them to set up dynamic data downloads without needing to reload the page again. Thanks to this, the resulting application is much faster than the average front-end application.
In simple words, MERN is a full-stack web application development solution that follows the traditional 3-tier architectural pattern. This includes client-side development with React, Backend logic, and runtime environment with Node and Express, and the database tier that comprises MongoDB.
Now when it comes to the reason why to use MERN is that first MongoDB works extremely well with NodeJS. This means storing, manipulating, and representing JSON data at every tier of the web application incredibly well.
Moreover, the combination of these technologies means that JSON data will flow naturally from the frontend to the backend. This makes building applications faster, more efficient, and reasonably easy to debug.
All these great advantages of MERN make it the most preferred choice for web developers of today.

MERN is one of the most powerful tech stacks available in the market. The harmonious alliance of four components included in the MERN stack helps make it a more comprehensive solution. However, if you prefer to work with Angular rather than React, you can just convert it to MEAN stack.
