Benefits of using Progressive Web Apps(PWA)
It is not something like an innovative concept in the software industry. As such designs have been created many times on the web platform with different strategies in history. The mobile-friendly websites are already there which is sharing the same concept as this. PWAs, however, present all this and more further without dropping any of the existing features that make the web great.
PWAs can be cached by the device’s web browser and used even when the user is in offline mode. It is based on the saving of data that users earlier accessed, for instance, pages. If a user tries to access those that they have not visited online, an application can show a custom offline page. This ability is imperative for retailers, as it enables them to restrict users from abandoning their catalogs and intensifies customer retention.
Another benefit of PWA is that they are being designed like mobile applications while still having the full functionality of websites with effective data and database access. It is the responsibility of the developer here to take care while developing a web application which is having the same user experiences as a mobile application by taking full advantage of existing frameworks and libraries. What makes PWA different from the native applications lets say is that you can get access to them through URLs as we discussed earlier and that they are for indexable by search engines. Enterprises can get significant advantages by doing it.
PWAs use efficient caching algorithms for serve text, images, and other content, which allows users to act like websites and remarkably enhances the operating speed. Simultaneously with the enhanced operating speed, excellent performance is an extra added quality that has an impression on user experience and growth rates. PWAs can be helpful to retailers and content providers as it facilitates a confident user experience than mobile applications by enhancing retention and customer loyalty.
Zero installs & No app store submission
Since it is not a platform-dependent mobile application so it takes very little time to download, and visitors do not need to route through Google Play or the Apple Store, but they can directly download the application onto their device without the necessity to undergo some tedious and deliberate App Store submission process.
Also, as PWA’s are web-based applications so no need to go through Apple’s App Store, Google Play, or Windows Phone Apps time taking process and can be push production build(or updated build) without following any approval process and all the updates will be automatically downloaded and updated when users relaunch the application.
PWA also allows creating the push notification the same as any mobile application has it. It allows businesses to the great capability of advertising the content. Like for any e-commerce sites, it could be a game-changer in sales, as it will directly be displayed on the device’s screen with an application icon and getting read far more easily than any advertising e-mail, or for any ticket system, give a status update to the ticket reporter via push notification, etc.
The web application manifest is a predefined file with a predefined format that contains the metadata associated with a web application. It including application name, application icon related details, URL to launch the web application, configuration data, display mode, etc. This data will be useful while listing the application on the home screen with the native application.
The service worker is one of the core parts of PWA. It is a JS file which operates as a type of web worker. The service workers work separately from the main browser thread. This proposes a distinct approach from conventional web programming — the API is non-blocking, and can send and receive information within various contexts. You can give a Service worker something to work on and get the result whenever it is available using a Promise-based approach. In short, it provides a scriptable network proxy in the web browser to execute the web/HTTP requests programmatically.
We can also add and define web storage, web assembly, database libraries, and application cache control to the technology
