Thus for ecommerce businesses, it is essential to employ the best technologies to leverage the benefits of a proliferating industry.

A respected ecommerce platform is scalable, consistent in display and maintains its integrity throughout. And for this, the CTOs of an ecommerce company will need to have a technology that renders strong support. Here Node.js ecommerce will come as a rescue.

Developing a Node.js ecommerce application will give you (IT business owners) best results by maintaining balance between user and application. In addition, Node.js helps in minimizing the loss or damages and gives best results without any hiccups.

Therefore, in this blog, we will see the basics of ecommerce. Moreover, we will have a close look as how Node.js will help in developing a state-of-the-art ecommerce web application.

What is ecommerce?

In simple words, ecommerce is a process that involves buying and selling of goods over the internet. The first ecommerce transaction happened on August 11 1994 and since then the ecommerce market has been expanding. As per a Statista report, the total ecommerce sales will reach up to a massive $6.542 trillion by 2023.

Moreover, with the outburst of the global pandemic, the ecommerce industry rose to a new high as people preferred buying things online.

Now, let us look at the impact developing a Node.js ecommerce application will have on your business.

Options to build a Node.js ecommerce website

There are basically two major options to build a Node.js ecommerce website:

·         Node.js ecommerce app with MEAN/MERN Stack

·         Node.js ecommerce app with Microservice Architecture

Node.js ecommerce app with MEAN/MERN Stack

The MEAN/MERN stack is an ideal choice for an ecommerce web application, especially in the initial stages. This is because the technology has the capability of responding quickly to the increase in traffic.

Now a question might strike you: How does the MEAN/MERN stack is able to handle the pressure so easily? The answer lies in the capabilities of the different components in the MEAN stack.

MongoDB: The database is based on NoSQL and it is incharge of execution and exchange of data storage. Through this, the Node.js ecommerce app will run smoothly without any server problems.

ExpressJS: It is the backend web-based framework whose main work is to develop web apps by rendering smooth interfaces.

AngularJS/ReactJS: The main purpose of AngularJS is to provide automatic view synchronization to the web development process.

NodeJS: It is lightweight and efficient as it is built on Chrome’s V8 JS engine. Moreover, it uses a non-blocking and event-driven input-output model to maintain its efficiency.

Process developing Node.js ecommerce web application with MEAN/MERN Stack

Being an open-source JavaScript framework, both the stacks (MEAN/MERN) are ideally a good choice for Node.js ecommerce development. Here is what exactly happens in the background:

·         It begins with Angular.js where all the requests are processed that are emerging from the client-side

·         After the requests are finished, it enters Node that controls the process on the server-side

·         Completing the above process, the request then proceeds to Express.js. At this point, it asks for the access to the database

·         After this, Mongo gathers the data as soon as the request is accepted and then it proceeds to Express.

·         Finally, the response is sent to Node which sends it to Angular.

An ecommerce website with a MEAN/MERN stack will be able to serve atleast 10k users. This is ample for a website in its initial stages.

Node.js ecommerce with Microservice architecture

Node.js and Micro services truly complement each other as it supports several frameworks such as Seneca.js. A Node.js ecommerce web application is scalable as it divides several functionalities into small suites.

Aesthetically too, Micro services is a better option to develop an ecommerce web app. It is exposed to clients via REST APIs so that the web app can communicate through an API gateway. Here is how an ecommerce oriented backend micro services architecture looks like:

If ecommerce companies adopt the micro service architecture pattern, there are several advantages. With the architecture pattern, there is an opportunity to code services that are independent of the database and programming language. Besides this, it eliminates the long-term commitment to the tech stack and cuts down the operations costs as well.

There are several examples of ecommerce businesses opting for the micro service architecture pattern:

eBay has employed the micro service architecture and has scaled beyond a billion users. This is because it is dynamic architecture and renders the ecommerce platform an opportunity to grow.

Another example is Cadenza which is a subscription based ecommerce platform. This platform too has used Nodejs for ecommerce web app development through microservice architecture. The ecommerce platform shifted from MEAN stack to microservice as they faced a hard time in managing 125 APIs.  The APIs were of different categories such as user management, product management, payment management, etc.

In addition, they also faced repetitive app crashes which distorted their overall user experience as well.

Building Nodejs for ecommerce is beneficial with both MEAN stack and Micro services architecture. MEAN Stack is convenient and easy to learn for the developers. While on the other hand Microservice is for the IT ecommerce business owners who already have monoliths.

In addition, the Microservice architecture gives complete control to the developers. Because of this, it is easier for them to build scalable ecommerce web applications.

The realm of ecommerce is ever evolving and thus Node.js for ecommerce becomes even more important. Node.js is a hot skill. Thus, it is essential for the CTOs to be careful while finding good Node.js developers. The future of your ecommerce business hugely depends on how you design a website. Therefore, better choose a good team composed of able developers.
