Expensive Consequences of E-Commerce Slowness
In the fast-paced realm of online shopping, being speedy means money. Research has found repeatedly that even one second increase in page loading time translates into a significant decrease in conversion rates. When retail companies use outdated and overly bulky off-the-shelf e-commerce themes, there is a risk of legacy architecture incapable of handling numerous concurrent users at sales peaks, such as Black Friday or during festival times.
For managers interested in expanding the capacity of their e-commerce stores, the technology stack used behind the scenes turns out to be the most crucial decision they have to make. For this reason, enterprise-scale businesses start moving away from standard CMS and towards custom MERN stack solutions.
Factors that Make MERN Stack Unique
The word MERN stands for four extremely powerful and JavaScript-centric technologies – MongoDB, Express.js, React, and Node.js. In contrast to conventional frameworks where developers need to link different programming languages in their backend and frontend application layers, the MERN stack is based exclusively on JavaScript.
MongoDB: An adaptable and NoSQL database that can cope with huge catalogs of products and dynamic data of users without fixed tables.
Express.js and Node.js: A super-fast backend layer that performs processing of various user requests simultaneously and does not block the server.
React: A high-performance frontend library that renders user interface instantly.
All of these factors make the development process quicker and enable fast data flow directly from the database to the user's screen.

Scalability for Increased Product Categories
Another key drawback of the standard relational database is its ability to deal with complex combinations of products (size, color, material, seasonality). As the number of products increases to hundreds and even thousands, the speed of queries in the database decreases, which slows down your web resource.
In MongoDB, part of the MERN, all information is stored as flexible JSON documents. Consequently, in case of a need for a new category of products that needs totally different parameters, there are no problems at all with that. Moreover, the event-driven architecture of Node.js makes it possible to manage tens of thousands of checkouts simultaneously.
Exceptional UI/UX Using React
Consumers in today’s world want to have smooth and application-like experiences while browsing using a regular web browser. In case a customer adds something to his/her shopping cart, the icon needs to change instantly without requiring the entire webpage to be refreshed.
This is where React comes into play because of its ability to use a "Virtual DOM." React updates only the particular components that need to change, thus offering hyper-responsive product filtering capabilities, instant search bar functionalities, and smooth checkout processes.
