Importance of Ecommerce PWA


Let’s have a look at Why Ecommerce PWAs are essential?

Nowadays, a major chunk of customers uses their mobile for browsing through the store for shopping. So the webstore owner needs to focus on that part of the customer group.

On the other hand, many customers from the mobile user group avoid downloading the app at the start when they are ordering for the first time from any e-commerce site.

The reason behind that, the native application needs more space in their respective devices, which sometimes creates problems for them.

On the other hand, if the store owner has a PWA for e-commerce store, then it can act like a native application for the user without requiring much space.

In comparison to native apps, the PWAs are faster and also work in poor network connections.

When to Develop Ecommerce PWA

There are some cases by which the store owner will get to know when they need to develop a PWA for their webstore:

  • The store owner who has just started their online store or is new to the e-commerce business.
  • In case, the store owner can see a decrease in the growth of the conversion rate on their website.
  • The store owner wants to develop a native app for their webstore to increase revenue, but they are on a tight budget.
  • To provide a great browsing experience for the mobile user.
  • Focus on mobile users as their numbers are more.
  • The store owner doesn’t want to publish their app on the store.

Prerequisite to Build Ecommerce PWA


Below are some points which need to be followed before developing PWA for a webstore:

I. Create an app shell

An application shell (or app shell) architecture is one way to build a Progressive Web App that instantly loads on your user’s screens, similar to what the user sees in native applications.

With the help of an app shell, the PWA perform fast with high performance.

This element is essential for an application with dynamic content and relatively constant navigation.

II. Service Worker

A Service Worker helps the Progressive Web Application to work in offline mode or poor internet connection, so it is such a main component which PWA should include.

This network script keeps scanning the system, and it determines where it should download content – from the cache or server.

Note- HTTPS server is needed to implement it.

III. Manifest file

The manifest file contains all the relevant data about the PWA such as the splash screen. The splash screen appears at the loading time of the application which the user will able to see.

It is also used to add the description of the PWA, PWA name, application icon, etc.

IV. Push Notification

To make the PWA similar to the native application, it’s worth enabling the push notification into it. It helps a lot to attract more users and also helps to retain the existing ones.

The service worker and Push API is the main factor behind the functioning of push notification.

Benefits of Having PWA of a Webstore
