Re-Shape Web Development With Progressive Web App
By now, you might have heard a couple of times that progressive web apps are the future of mobile. They are expected to give native app experience to users. Progressive web apps will drive the mobile web forward, bringing balance between the web and native applications. It is an upcoming technology that helps app developers India to reach out large user base beyond the walls of the rigid App and Play store. Well, that's all fine but, what is exactly Progressive Web App?
“In simple words, Progressive Web App takes the benefit of modern browser capabilities to deliver native app-like user experience.”
Native applications developed by mobile app development company are capable of sending a push notification, work in an offline manner, load on the home screen and so on. Mobile web applications that accessed in the browser does not hold capabilities to act like native apps. Progressive Web App is the way to fix things through a development of new web API using modern browser capabilities to deliver native app like experience.
How Does Progressive Web Apps Decide The Future Of Web Development?
In general, whenever you click on a website link, your browser will send the request to the server. Server will again send back the requested content to the browser. In this way, current request and response are generated.
Website extended with Progressive Web Apps adds an extra layer in the entire process. Here, when a user clicks on the website link, instead of requesting web server, the request query is passed to service worker that shows website content regardless of internet connection. It means, now we can develop a full-fledged offline version of our existing websites that allow users to enjoy seamless browsing experience if in case they drop their internet connection in between.
Not only that, Google has also introduced some interesting features in chrome browser followed by Firefox and Opera in their browsers.
