Developing a PWA Using Angular 7

For quite a while we have been noticing a huge interest in Progressive Web Applications (PWAs) in the front-end world.
More and more companies develop applications using the concept. Users creat catalogs (PWA Stats), where we may find the information about use cases and positives (improving conversion, increasing the number of subpages visited during the session or time spent on the page). Market giants, such as Microsoft also promote the technology by allowing developers to add PWA applications to the Windows Store.
