Progressive Web Apps (PWAs) are websites that look and act like apps; they’re fast and work offline, and can even be pinned directly onto a device’s homescreen. Plus they function independently of browser updates and are discoverable via search engines!

Progressive Web Apps differ from native mobile applications in that they utilize modern APIs to deliver an immersive user experience that works across browsers and devices. PWAs support an array of features like push notifications, offline functionality and integration into operating systems.

Building a Progressive Web App doesn’t have to be difficult or time consuming – in fact, it may even be simpler than creating traditional native apps! Before diving in and starting to code though, make sure you set goals that can be accomplished using available resources. Selecting an efficient technology stack such as AngularJS ReactJS Polymer could make this task simpler than expected!

Google Lighthouse, a free open-source tool included with Chrome DevTools, can help you evaluate the performance of a PWA. The benchmark criteria for any successful PWA include basic elements, like testing its mobile-friendliness and verifying HTTPS service, as well as more advanced items, like installing a service worker and web app manifest. Other important considerations may include caching strategies (stale-while-revalidate/preload), resource prioritization/adaptive loading for different network connections and caching strategies (stale-while-revalidate/preload), caching strategies (stale-while-revalidate/preload), caching strategies (stale-while-revalidate/preload), resource prioritization/adaptive loading for different network connections as well as caching strategies (stale-while-revalidate/preload).
