Progressive Web Applications

A Progressive Web App (PWA) is a mixture of app and website and is currently on everyone’s lips. The advantages of both applications are combined and used for a better user experience. With the mobile first approach, the classic desktop site is currently dying out anyway. You can find out here how classic native apps will also have to struggle with PWA and why the trend can no longer be stopped.

Functions of Progressive Web Applications

There are over 3.3 million apps in the Google PlayStore and around 2.2 million in the AppStore. The user quickly loses track of things. In view of the oversaturation of the market, so-called progressive web apps (PWA) were created. These are not installed, but carry out their functions via the browser. At the moment, all commercially available browsers are even better adjusted to deal with PWAs. So the trend is towards Progressive Web Application Development and away from the native app Development. On the one hand, this is due to the low hurdle for the user. Installing an app and thus giving up valuable storage space means much more effort and effort than opening a website with the browser.

To this end, the operator of the PWA receives control back from the download stores. The lengthy authentication process is eliminated, as are community guidelines and special design specifications. In addition, there are no corresponding fees if PWAs are sold.

The boundaries between app and website are disappearing

What else does the PWA have in common with an app?

What then does the A in PWA stand for if everything will take place in the browser in the future?

Because they perform the functions in the browser that apps used to take over.

  1. Outwardly, they are similar to the design of an app. For first-time users, it will be hard to tell the difference.
  2. They cache content, work in offline mode and with poor reception.
  3. They can be placed on the start screen. The bookmark opens the browser and accesses the content of the PWA directly. It feels just like an app!

The heart: service workers

Service workers are the most important part of PWA. These contain JavaScript that lets your app run in the background. This means that it can take over all functions such as updating or caching. Service workers take on “invisible” tasks that contribute to the optimal use of your services. They keep the PWA up to date so that users don’t have to wait a long time for an update to load. They regulate offline access accordingly and only show the missing Internet connection when it is needed – not beforehand.

Service workers are therefore fundamentally important for PWA. They’re the reason people think they’re using an app when they aren’t.

Web manifest

With the Web Manifesto, the PMA becomes even more intuitive for the user. This manifest makes it possible to save the PWA on the mobile interface. The manifest thus fulfills a classic app function. The manifest also enables useful services such as push notifications and the use of geolocation. This also makes the PWA more visible than an open tab in the browser. With the full-screen mode (there is no URL bar etc.), a progressive web app can no longer be distinguished from a normal app.

Mobile first

Every website has to be responsive by now. There is no getting around it. It remains to be seen in the near future whether it will have to be based on PWA standards in the future. The growing popularity of browser support and increasing conversion rates, especially with occasional visits, speak in favor of PWA. In general, the future stands and falls with support and standards on the browser side. The potential seems unlimited.

Takeaway

  • PWAs are app-like websites
  • PWAs do not have to be obtained from the Play Store, AppStore, etc.
  • Service Worker (JavaScript) enables (almost) all functions of native apps
  • PWAs are the future
