Progressive Web Application (PWA) is a type of web application that uses modern web technologies to provide an app-like experience to users, combining the best features of web and mobile apps. Using PWAs makes it easier for the organization to manage single application infrastructure work on any device (desktop, tablet, mobile), regardless of the operating system, and enable access through a web browser. PWAs are built using web technologies such as HyperText Markup Language (HTML), Cascading Style Sheets (CSS), and JavaScript, and can be easily installed on a user’s device, just like a native mobile app, without getting into the hassle of registering applications with app stores.  They can also work offline, which makes them ideal for working under lower bandwidth with poor internet connectivity. PWAs use a service worker to cache app data so that users can continue using the app even when they’re not connected to the internet.
For example, an insurance company can create a PWA that allows policyholders to access their policies, make payments, file claims, and receive updates on the status of their claims. By using a PWA, the insurance company can offer a more streamlined and user-friendly experience for customers, regardless of the device they are using.
