jStorage is a small cross-browser key-value store library for persisting data locally in the browser, supporting strings, numbers, objects, arrays, and XML nodes. It also offers TTL-based key expiration and cross-tab change notifications, effectively acting as a local PubSub mechanism.

Use cases

• store user preferences in the browser
• cache data locally across page reloads
• persist key-value data in old browsers including IE6
• auto-expire stored keys with TTL
• sync state between browser tabs
• simple client-side pubsub messaging

When to choose

• you need broad legacy browser support including old IE
• you want a tiny dependency-free key-value storage layer
• you need TTL expiration or cross-tab notifications

When to avoid

• you only target modern browsers and can use the native localStorage API directly
• you need large-scale or indexed client-side storage like IndexedDB
• you need an actively developed project with new features
