PWA & Headless Commerce 2023: Everything You Should Know

In the eCommerce & technology world, the terms “headless” & “PWA” often go with each other. These can lead to some confusion, especially for non-tech-savvy store owners & novice developers. In this article, we will explain everything you need to know about headless commerce & PWA, their differences, as well as how headless PWA can benefit merchants. 

Understand the technologies

Headless Commerce

What is headless commerce

Headless commerce refers to selling online using the headless architecture. 

To understand headless technology, it’s important to understand the different components of an eCommerce website (If you do not know about it already)

An eCommerce website is a combination of its front end and backend. Whereas the front end is responsible for the store designs & user experience, the backend takes care of all website data & operation. 

The traditional eCommerce website model that we are common with works in a monolithic structure. This means the frontend and the backend are attached to each other. 

Headless Commerce, on the other hand, has the frontend decoupled from the backend. Those two are then connected with each other via API (Application Programming Interface).

headless vs monolithic

This backend-agonistic approach paves a new way for website developments, granting much more freedom & endless possibilities than ever before. 

The benefits of headless technology:

  • More flexibility: Different teams of your businesses (e.g your IT & your Marketing team) can work on the frontend & the backend simultaneously without affecting each other. 
  • Better personalization: Marketers can test lots of ideas and options to achieve the best-personalized user experience without interrupting shoppers’ buying journey on the frontend. 
  • Maximize speed: It’s easier to optimize speed for the frontend without affecting the backend. Also, you can build a data cache layer between your frontend and your backend, which can improve speeds. 
  • Better & faster customization & integration: you can customize your backend and frontend at the same time, making it faster to finish with fewer risks. 
  • Better omnichannel experience: Via API, one eCommerce backend can connect with several frontend devices, from traditional ones like phones or desktops to the less unconventional ones like Apple Watch, Billboard, IoTs. Thus, you can easily deliver your content to many digital touchpoints.

PWA (Progressive Web App) 

What is PWA? 

PWA stands for a technology that helps significantly improve user experience on web browsers. 

PWA is installed on the website frontends to make it load faster & smoother while enabling some functions of mobile apps like “push notifications” or “add to home screen”. App-like functions like these also are what set PWA from AMP (Accelerated Mobile Page) & responsive web designs. 

The benefits of PWA 

  • Better performance: PWA can improve your website loading page, specifically your mobile loading page from two to four times faster. 
  • Embrace mobile commerce: PWA shares some functions of the native mobile app. For example, it lets users add your website to their home screen & let you notify them on their mobile, which can improve your site traffic, engagement & conversion.
  • Save cost for mobile development

The difference between PWA & headless technology

We guess it’s not difficult to spot the difference between those two after understanding their definitions.  

Essentially, headless technology is about the relationship between a website’s frontend & backend, while PWA is a frontend application. 

Both have distinct benefits & they are independent of one another. You can build a headless website without PWA and vice versa. 

However, being interested in eCommerce or website technology, you may have seen these two are paired with each other lots of times. 

This leads us to another question: 

How headless PWA can significantly benefit merchants?

Whereas both two technologies have so many merits, the perk of headless PWA lies in only two words: user experience

With its flexibility, headless commerce lets merchants create storefronts & customize frontend experiences more easily than ever before. 

You can create different storefront designs for different touchpoints, from desktop, mobile, to Apple Watch, & IoTs. As each version of your website is optimized for its screen size, you are sure to offer a more addictive customer experience, thus, generate more sales & satisfaction. 

Moreover, without worrying about the backend, it’s easy to perform localization & personalization on the frontend. This may be quite restrictive to implement with the traditional architecture. 

Meanwhile, PWA makes your web speed faster & enhances the mobile experience. Especially when most online transactions now happen on mobile, it’s an urgent demand to have a lightning-fast web page (under 2 seconds, as Google suggested). 

When combined together, headless PWA can help eCommerce businesses to maximize their website’s user experience. It gives more room for marketers to implement website strategies for conversions while ensuring a smooth & effortless buying journey that customers love. 

Therefore, lots of eCommerce big guys like Lancome, Lego use headless PWA to drive sales online.  

PWA: headless or not?

Since it’s totally possible to achieve PWA with or without headless, many merchants will wonder if it’s worth losing the heads. Changing a monolithic eCommerce website into a headless structure seems to be a big thing, and evidently, it needs lots of consideration. 

Thus, here are the most significant differences between a PWA & headless PWA for your reference.

The bottom line

Headless technology is expected to be the future of eCommerce, opening up more freedom for businesses to provide top-notch user experience & revolutionize their selling experience. Meanwhile, PWA when used with the headless architecture, can help create a much faster frontend & improve mobile engagement with native-app features. 

While you can implement PWA without going headless and the other way around, headless and PWA are eCommerce businesses’ favorite duo. The pair helps companies craft the desirable eCommerce website for all devices that prompt sales effectively. 

We hope that this article has helped clear the confusion between headless & PWA.

Although it is possible to adopt PWA without becoming headless and vice versa, headless and PWA are quickly becoming the preferred combination for eCommerce companies. The duo provides assistance to businesses in the creation of appealing eCommerce websites that are optimized for all devices and efficiently stimulate purchases.

Headless PWA is a new technology that combines the flexibility of a headless CMS with the power of a progressive web app. With headless PWAs, you can create web apps that are fast, dependable, and visually appealing. Headless PWA works by separating your web app’s front-end and back-end. This means that the front end can be built with any framework or technology, and the back end can be run by a headless CMS. This allows you to select the best tool for the job while also making it simple to update your content without having to redeploy your entire app.
