The service worker actually acts as a proxy server between the web application and the browser, as well as the network (if available). It allows (among other things) to describe the correct offline behavior of a web application, to intercept network requests and take appropriate action based on network availability, and to update the data located on the server when it is accessed. They also have access to push notifications and background sync APIs.
