Progressive web apps

More and more people are going online with mobile devices; many people no longer own a desktop computer. The different screen formats are now well under control with responsive web design. The new challenge is that the Internet connection to our smartphones and tablets is not guaranteed everywhere. In addition, web applications on mobile clients are competing with native iOS, Android and Windows Mobile applications, which each form a seamless integration with the devices’ hardware. Yet the development of native applications is more expensive, since the most important platforms should be supported as a minimum. Frameworks such as Cordova, which package web applications into native program shells, are also only workarounds and have limitations.
Thanks to the HTML5 APIs, progressive web apps function like native applications, can also be installed, are offline-enabled and do not have to be distributed through a store.
In this training course, you will learn how to create state-of-the-art, high-performance and reliable web applications based on progressive web apps, using practical examples.
