A Svelte store wrapper that persists state to localStorage or sessionStorage, with optional cross-tab synchronization via storage events. It supports custom serializers, read/write hooks, and error handlers.

Use cases

• persist user preferences like theme across page reloads
• keep shopping cart contents in localStorage
• sync Svelte store state across browser tabs
• store form drafts in sessionStorage
• reset a persisted store back to its initial value

When to choose

• you use Svelte or SvelteKit and need state to survive reloads
• you want cross-tab state sync with minimal setup
• you need pluggable serialization or storage backends

When to avoid

• you need server-side persistence or a database-backed store
• you're not using Svelte's store contract
• you need to persist large datasets beyond localStorage size limits
