Everything You Wanted To Know About Progressive Web App
Well, you may have already heard about ‘progressive web app’. It has been described as the future of all mankind. You may have heard some incredible things about a progressive web app. So we are not going to get into that. First and foremost, let’s define it. Well, it uses the web capabilities that we are using today to come up with an app-like experience for the user.
We all know what native app store apps are capable of. They work really well on our smartphones. But when we access one of those mobile web apps from a mobile web browser, it is not the same. The experience is underwhelming to put it lightly. And apparently, progressive web apps have the ability to fix this problem. Progressive Web Apps get it done with the help of new design concepts, new web APIs etc. We are strictly talking about browser mobile web applications here and nothing else. Why do we have such a limitation? Well, the browser comes with limited features in the first place. And then there are API standardization and security reasons attached to it.
Progressive Web Apps makes it possible for you to have the same experience of native apps when you deal with the mobile browser. It runs in a secure container, which everyone can access. In short, we can see that it is a collection of technologies, web APIs, and design concepts. All these elements provide an app like experience.
Progressive Web App makes use of the technology named Service Workers. It is a really powerful technology. But it can be confusing to many. It makes a lot of things possible including content caching, background content updating, push notifications, offline functionality etc. It also takes care of the connectivity changes.
You can describe Service Workers as a proxy. In fact, that is the ideal way to put it. You will be able to listen to events including fetch. The best thing is that you can exert full control on the event. You will also be able to check cached data. The script behaves like a proxy for the request.
We have already mentioned the incredible power of Service Workers. We also have to mention the flexibility it offers. And that is exactly what makes it complicated as well. You will be able to find samples of Service Workers.
We are talking about a simple design concept here. Developers can take advantage of this simple design approach. The caching capabilities of service workers will be an added advantage here. Without any doubt, it is a straightforward approach.
As far as Progressive Web Apps are concerned, we can say that it is a combination of marketing strategies, design patterns, and Web APIs. Service Workers provide the functionality of working in the background. App Shell allows it to load faster. In short, a web developer can dream of building mobile app experience with the help of Progressive Web Apps.
