Welcome to What’s New in PWA! This post will cover what is new in the world of Progressive Web Apps and PWABuilder over the last year or so. We’ll take a look at some of the latest browser capabilities, go over some numbers on PWA adoption, and spotlight some Progressive Web Apps we’ve recently encountered through the PWABuilder service.

Let’s jump into the latest browser capabilities.

New Browser Capabilities

The last year has seen browser capabilities continue to expand to support more flexible Progressive Web Apps. Let’s highlight a few that have made Progressive Web Apps more flexible.

Window Controls Overlay

Window Controls Overlay is a newer feature that allows your Progressive Web App to look more like a native application by allowing usage of the space normally reserved for the browser’s window controls. This feature is available in both Edge and Chrome.

Windows 11 Widgets

Progressive Web Apps running on Edge can now define widgets for the Widgets Board on Windows 11. This is another great way for your app to integrate more fully on a native operating system.

Edge Side Panel

Progressive Web Apps running on Edge can now make use of the Edge Side Panel, which allows your app to run side-by-side with other content. This is great for productivity apps and apps that may be used in conjunction with other content.

PWA By The Numbers

All of the following data is sourced from the Web Almanac, a crowd sourced project for tracking web development trends. We’ll be taking a look at some of the data associated with progressive web apps, such as service worker and app capabilities usage.

Service Worker Usage

First, let’s take a look at service workers. Right now, just under 2 percent of all websites employ the use of a service worker. However, this number increases when looking at only the most popular websites. For the top 10,000 sites, service worker usage is around 8 percent. This makes sense, as more popular sites are more likely to to have the support required to update to the latest web technologies.

Let’s also take a look at what service worker features are being utilized:

App Capabilities Usage

Though many app capabilities aren’t exclusive to Progressive Web Apps, their usage is still a good indicator of how developers are making use of the modern web. Let’s take a look at some of the most popular app capabilities in order:

  1. Async Clipboard API - 10 percent
  2. Web Share API - 9 percent
  3. Media Session API - 7.5 percent
  4. Device Memory API - 6 percent
