Benefits/advantages of Progressive Web Apps:

The following benefits can explain to you clearly why progressive web apps are the talk of the town:

  • You do not require multiple codebases for your app if using a progressive web app model. It helps you maintain everything under one single roof at a cheaper price than that of if you opt for a full suite of mobile apps.
  • You get easy access to user retention features such as offline usage, push notifications, and background syncing, which sometimes may not be available even with native apps in the traditional web.

How to get your website on a Home screen?

If your website appears on the home screen of your users, it exceptionally increases user retention and engagement. Progressive web apps make it possible within no time. Here is the procedure you should follow to get your website on the home screen of your users.

#1: Configuring the manifest

Your website should be able to show the browser about the progressive web app, and it is possible with presenting a JSON file. This file should include information about how the app should respond, how it defines specific criteria, and what images or icons should be used to make it available. This will help in creating the best app-like experience for your users and meanwhile, you can craft your progressive web app in such a manner.

PWAs leave the choice to you to decide which icon and title to be used when your website appears on the home screen, along with setting the background color and other privileges while launching the app. You can even change or apply a color to the navigation bar of the website to match with the theme color.

#2: Setting up a service worker

A service worker is the backbone of a progressive web app that runs as a script individually from the web page in the background. Also, to make your app work offline effectively it should be used to cache assets and files and the experienced professional service workers capable of doing it easily.

Meanwhile, you can send or receive messages for supporting push notifications or background syncing.

#3: Developing a custom install experience

This is the crucial part that gets success for you. You would have already introduced manifest and service workers to enable your PWA’s working functionality.

Now, your app requires a small trigger that can motivate the users to install it. If the user is technically savvy, they can install the application by themselves. But for those who do not know how to go with it, you can provide simple instructions to install the application.

Remember that the installation prompt can happen either before or after the user creates an account. So set the code accordingly so that you do not lose users.

#4: Analysing performance

After completing the aforementioned procedure, finally, comes here the testing part. Enable automated testing using Google Lighthouse, which has its own PWA tester.

This procedure is simple to access and perform as well. If you are using the Chrome browser then go to the Developer Tools where you can find the Audits tab. Under that audit tabs select the Progressive web app option and click the generate report.
