=== Service Worker ===
As a type of Web Worker, the Service Worker is a also a JavaScript source file that runs in the background of the browser on a thread that is separated from the main thread. It acts as a proxy server between the application on the browser and the Internet. It is euqipped with utilities that help intercept network request and perform some actions with that requests. Those actions include relaying the request to its intneded destination, dropping the request, caching of the request contents or responding to the request with the cached data. In addition, it can act on the requests differently based on each of the request or the current network status.
For those utilities, the Service Worker enables your applications to be capable of working offline. It allows the developer to write the strategies for that such as "network-first-then-cache", "cache-first-then-network" or "cache-only"...etc. Service Worker is an essential component of any Progressive Web App (PWA).
