For a long time, developers had to choose whether they would build a (mobile) web site or an app to reach their audience. Both have their own set of advantages and disadvantages. Web sites are platform independent, but lack functionality and cannot be used offline. Apps deeply integrate with the device on which they are installed but have to be developed for each platform and are not as easily updated.
The solution for that is called a Progressive Web App. Basically, it’s a website with added functionality. And there are a number of featues that a PWA requires.
First, a PWA-enabled website should contain an SSL certificate in order to prevent Man in the Middle (MitM) attacks between the app and the backend.
Sceond, it contains a JSON file called a Web Application Manifest. This file holds information about the name of the application, links to the web app icons or image objects and details about the splash screen.
Although the technology is promising, there are still some hurdles to be taken. Not all features of all mobile devices are supported yet. So is Touch ID not useable without an extra layer like Phone Gap or Cordova. Also, push notifications do not work on iOS devices because background processes are required for service workers and not supported (yet).
The word “progressive” in PWA stands for the idea that although not all functionality is supported by every device, the features that are enabled will work anyway, without breaking the entire app. So if push notification do not work, the site is still able to cache and refresh data. Basically, it’s the next step after progressive web sites, that enabled developers to build one site for many different screen resolutions and input types.
If PWA’s are going to be the next big thing is still a question. But they will pave the way for a smoother user experience across devices and a more generic design of apps anyway. The gap between native apps and websites has become narrower, although still not fully bridged.Overzicht blogs
