svelte-persistent-store

• Persists Svelte stores in localStorage or sessionStorage for state preservation across page reloads
• Designed specifically for Svelte applications (not framework-agnostic)
• Provides persistent versions of Svelte's core store types:
  • writable
  • readable
  • derived
• Uses JSON serialization to store values since web storage only accepts strings
• Key features:
  • Simple API matching Svelte's native store interface
  • Automatic synchronization between storage and store state
  • Supports both localStorage (persistent) and sessionStorage (temporary) backends

Target audience: Svelte developers who need to maintain application state across page refreshes or browser sessions.
