What is service worker?

A service worker is a script that your browser runs in the background, separate from a web page. A service worker enables features that don't need a web page or user interaction. Service workers can do things like: manipulating cache resources, handling browser requests, providing offline access, and many more. They can also be used to improve the performance and reliability of web applications. Please note that this API is still under active development and has the potential to revolutionize the way we use the web.

Can I see the information about cache storage?

Yes, while analyzing the service worker, this web application checks whether the cache storage is available and operational in your browser or not. Sometimes plugins or applications disable the service worker together with cache storage in your browser. This web application populates a dummy cache storage while registering the service worker. In the end, it analyzes both metrics to see if everything is running smoothly.
