Out of the Shadows
summary
Explains how Service Workers use the fetch event and the Cache API to provide offline fallbacks and saved-page lists, implementing patterns like cache-first and network-first (check cache, then fetch-and-stash). Gives concrete examples—an offline HTML “dinosaur” page, reliably loadable saved-post bookmarks, and an artwork that only shows when offline—and mentions the Google-backed sw-toolbox library and the requirement for HTTPS and same-origin scope.
