Web Storage (localStorage, sessionStorage, cookies)

Web Storage is not accessible from Service Workers: 1) Service Workers run in a different context and cannot access localStorage or sessionStorage, 2) They should use IndexedDB or Cache API instead, 3) This limitation is due to Service Workers' non-blocking nature, 4) Web Storage is synchronous while Service Workers require async operations, 5) This architectural decision prevents performance issues in Service Workers, 6) Applications need to use different storage strategies for Service Worker functionality, 7) This separation maintains Service Worker's ability to operate independently, 8) Understanding this limitation is crucial for proper offline-first application design.
