svelte-persisted-store

• A Svelte store that persists data to localStorage or sessionStorage, with cross-tab synchronization capabilities.
• Purpose: Provides persistent state management for Svelte applications by automatically saving store values to browser storage.
• Key Features:
  • Automatic persistence to localStorage (default) or sessionStorage
  • Tab synchronization (enabled by default)
  • Custom serialization support (defaults to JSON, can use libraries like devalue)
  • Error handling hooks (onWriteError, onParseError)
  • Value transformation hooks (beforeRead, beforeWrite)
  • Standard Svelte store interface with additional reset() method
• Target Audience: Svelte developers needing persistent client-side state that survives page refreshes and syncs across tabs.
• Usage Patterns:
  • Works like regular Svelte stores (subscribe, update, set)
  • Supports Svelte's auto-subscription syntax ($store)
  • Can be read with get() from 'svelte/store'
• Storage Options:
  • local (default) - persists across sessions
  • session - persists only for current session
