Client-Side Storage
Client-side storage refers to web technologies that allow data to be stored locally on a user's device (e.g., browser or mobile app) rather than on a remote server. It enables web applications to save user preferences, cache content for offline use, and maintain state across sessions, improving performance and user experience. Common implementations include browser-based APIs like localStorage, sessionStorage, IndexedDB, and Web SQL, as well as platform-specific solutions in mobile and desktop apps.
Developers should learn client-side storage to build responsive, offline-capable web applications that reduce server load and network latency. It's essential for progressive web apps (PWAs), caching strategies, and storing user-specific data like settings or form inputs without requiring constant server communication. Use cases include saving shopping cart items, enabling offline document editing, and persisting authentication tokens for seamless user sessions.
