The progressive web apps represent, according to many, the future of interaction with our smartphones, to exploit their potential in an innovative way. Let's see what they are and how they work.
The apps purchased in traditional stores allow you to perform many operations, impossible with apps for Mobile Web browsers. The progressive web apps are used to fill this gap with new Web APIs, new designs and new buzzwords: that is, they allow you to perform the same operations that you would expect to run with native mobile browser apps, with a system that uses standard basic technologies and is accessible by anyone on the web.
The concept of progressive apps indicates a set of technologies that work in harmony, to offer an experience similar to that offered by an app on the mobile web.
After discovering what they are, it is also necessary to describe how Progressive Web Applications work by observing their more technical aspect. The term โprogressiveโ indicates a "progressive improvement" obtained thanks to modern web functions. In this way, in fact, they can also work with older browsers that do not support the new features.
The Service Workers of progressive web apps
The Service Workers of progressive web apps are extremely powerful technologies, which upload offline features, offer notifications, background content updating, content caching service and many other functions. A Service Worker is a script that works behind the scenes, independent of your app, and activates in response to events such as network requests, notifications, connectivity changes and more.
It can be defined as a "proxy", given that this technology allows us to notice a particular event every time the request from the network starts. We can handle that event with full control: our script behaves exactly like a proxy for the request.
The great power and flexibility of Service Workers make them very complicated and developers generally use pre-established schemes to configure the most common uses, such as offline use: Mozilla and Google are at the forefront in this respect.
