Progressive Web App

For the past few years, you might have seen the term PWA (Progressive Web App) turning up all over the place on the web. Back in 2016, in the beginning, it wasn’t that big, but it has changed over time. It’s even expected to rise much more in the coming future and that’s one of the reasons why Google is focusing more on mobile user experience.

Progressive Web App Development

Progressive Web Application (PWA) is a web-based application designed with popular web technologies such as HTML, CSS, and JavaScript. It’s built to run on any platform, including desktop and mobile devices (iOS, Android). The purpose of PWA is to have the best possible webpage across all systems. To do that, web application content is cached in the device memory. Recent service worker advancements in the cache and push APIs allow users to receive push notifications or work offline. This is a benefit of PWA sites over other kinds of web pages.

PWAs applications don’t need separate distribution. It can be published to digital app stores such as the iOS App Store or Android Google Play but it’s not necessary. Developers can post the web application online, and users may add the PWA app to their mobile device home screen. 

Checklist for Progressive Web Apps Development

By developing a PWA, the goal is to deliver a product that functions similarly to a native app. To be defined as fully compliant with the spirit of the PWA, an application must meet certain conditions outlined by Google in its “Progressive Web Application Checklist” document:

  1. Faster after initial loading. High-performing sites engage and keep users better than low-performing ones, so performance is an important factor in the success of PWAs applications.
  2. Progressive. It could be used by every user in any browser. PWAs are web apps first and foremost, which means they must function across each browser rather than just one.
  3. Responsive. PWA should be accessed by users on any screen size – desktop, mobile, or tablet, and all content should be available at any viewport size.
  4. Installable. Without the need for an App Store, a PWA app should provide home screen icons.
