Top 5 JavaScript tools for Ecommerce Platforms

Ecommerce platforms are online systems that allow businesses to sell products and services to customers over the internet. Ecommerce platforms have grown in popularity in recent years as more and more people shop online. By 2023, online retail sales will reach $6.51 trillion, adding 22% to all retail sales, according to research by eMarketer and Statista.

JavaScript (JS) is a programming language widely used in developing ecommerce platforms. It allows developers to create interactive and dynamic websites. In addition to client-side development, JS can also be applied to the server side using technologies such as Node.js, enabling developers to use the same language both on the frontend and backend of web applications.

This article will walk you through the perks of using JavaScript in ecommerce and highlight five (5) top JavaScript tools for ecommerce.

Advantages of Using JavaScript in Ecommerce

  1. Improved User Interaction: User experience is crucial for any online store, as it often influences user retention. JavaScript enables you to create responsive forms, which adjust to various screen sizes and resolutions. This keeps users on board as they fill out forms during purchases, improving their experience.
  2. Enhanced Performance: The loading time of a website affects its user experience and search engine optimization (SEO). According to research, 47% of users expect a website to load in no more than two seconds. JavaScript allows you to load content simultaneously, which can help improve the performance of ecommerce sites and reduce page load time.
  3. User Personalization: JavaScript allows you to personalize content and products based on a user's search history, browsing history, and other factors. This can improve the product's relevance to the user and increase the likelihood of conversion.
  4. Cross-platform support: With JavaScript, businesses can create ecommerce websites that will work on any major web browser, allowing you to reach a broad audience. It can also be used to develop the backend for ecommerce platforms, web storefronts, and mobile applications. This versatility makes it a popular choice among developers, allowing them to use the same language across different platforms and enhancing the overall development experience.

Below is a list of five tools that can be highly beneficial for different aspects of an ecommerce platform.

1. Node.js Ecommerce Backend: Medusa

Medusa is an open source composable commerce platform built on Node.js with which developers can build custom ecommerce applications. Medusa is an ecommerce platform that provides a robust set of features for managing orders, exchanges, returns, customers, customer groups, products, collections, regions, prices, taxes, sales channels and more.


With Medusa, businesses can easily configure and manage multiple regions and currencies, integrate with various fulfillment providers, payment providers, and other third-party services using its plugin system, and use advanced pricing strategies with conditions based on the amount in the cart or promotions and discounts.

2. Static Site Generator: Gatsby

Gatsby is a static site generator and a modern web framework based on React.js. It is used to build fast, efficient websites, and web applications. Static site generation preloads the entire website at build time, resulting in faster load times and better performance.

In addition to using GraphQL, Gatsby allows developers to easily fetch and manipulate data from different sources, such as headless CMS, APIs, and databases.


Benefits of Using Gatsby for Ecommerce

  • Flexibility: With Gatsby, developers can customize the appearance and feel of ecommerce sites and even add interactive features like user reviews and product filtering.
  • Speed and Performance: As stated earlier, an ecommerce site's load time is vital. With Gatsby, websites are pre-rendered, which results in faster load times and improved performance. This is important for ecommerce websites, as customers are more likely to only return to websites that load quickly.
  • It is SEO Friendly: SEO helps ecommerce websites increase brand visibility, which leads to more customer visits and revenue increase. Gatsby websites are pre-rendered, which makes them easily crawlable by search engines. It helps ecommerce businesses to be be easily found by customers through search.
  • PWA support: Progressive Web Applications (PWAs) are web apps that can be installed on the user's device and work offline. By default, Gatsby websites are PWAs, which means that ecommerce websites can provide consumers with a more app-like experience.

3. Automated Testing: Nightwatch.js

Nightwatch.js is a Node.js-based automated testing framework used to test web applications. It allows developers to create automated tests that simulate user interactions, such as filling out forms and submitting data.

With Nightwatch.js, developers can write tests that can be used to test the functionality of web applications and their performance and usability across different browsers. This allows developers to focus on writing code while ensuring that their application works as expected.
