First of all, let's figure out what a Progressive Web App or PWA is. These terms denote the existence of well thought out algorithms of using applications for the user’s benefit. PWA is the best way for developers to make their web applications load faster. Furthermore, they are more productive.

In short, PWAs are websites that use modern web standards. This is precisely what makes it possible to install them on the user's computer or device. In operation, they function as independent applications. The most famous example is Twitter, which launched mobile.twitter.com as a PWA on React and Node.js.

A PWA web application works offline without the internet connection using the data cached during the last time a user dealt with the application. If you visit a website from Chrome on a desktop having the appropriate flags enabled, you will be required to download the web app.
