The Web's future is offline
summary
The Web can work offline; technologies that enable this include AppCache, Service Workers, localStorage, and IndexedDB. AppCache uses a manifest that must be versioned so updates appear on the next load and has explicit caching rules and gotchas. localStorage/sessionStorage store string key‑value pairs synchronously and support cross‑window storage events. The navigator.onLine property and online/offline events let interfaces adapt, while Service Workers intercept fetches for resilient offline‑first behavior.
