Progressive Web App Explained

The most straightforward definition of a progressive web app is a browser-based application that has the appearance and capabilities of a native mobile app. They are applications that are developed utilizing web-based technologies such as HTML, CSS, and JavaScript, among others. Progressive web applications can be run in any browser and are built to be very responsive. They can include all the features and functionality of native mobile applications, as well as a mobile design. Progressive web apps are designed to take over Native mobile app functionality without forcing the end-user to go to an app store or play store to buy or download something. Progressive web apps are developed with React and similar frameworks, hiring a React developer is ideal for developing a progressive web app.

The main advantage of progressive web applications is it doesn’t ask the user to go to an app store and download an app. Instead, users can get access to the app directly from the internet by clicking on a link or by a simple google search. This reduces the barrier to use, resulting in skyrocketed user engagement with applications.

Furthermore, like a smartphone app from an app store or play store, they can send web push alerts, function offline, and be accessed from the home screen. Tech giant like Tinder, Twitter, Alibaba, Pinterest, Uber, TikTok, Spotify, and Jumia has adopted progressive web apps for their business due to their ability to function on both Android and iOS without much change.

How Does a Progressive Web App Work?

A PWA must be downloadable and installable on your device (phone, tablet, PC, or Mac), with an app icon/shortcut and all. Each time a user accesses a progressive web app, it will download updates automatically in the background. When you update your web application, not just visitors to the app site, but also PWA users, will receive access to all new features without having to do anything.

A service worker script in a PWA which runs on the browser is responsible for doing background operations like alerts, push messages, and sync. When a user interacts with a PWA, the PWA can check their device’s capabilities and run a service worker script in the background to perform the task. To, store and display the details like the program’s icon, background color, name, short name, and so on to the user, PWA consists of a simple JSON file known as a Web app manifest. Only when PWA is launched does it start running in the background. This is how the progressive app works.

Why Progressive Web Apps?
