A tiny, type-safe wrapper for localStorage powered by Zod. Validate and persist structured data in the browser with full type safety.

  • ✅ Schema-based storage with Zod
  • ✅ Type-safe reads and writes
  • ✅ Easy to use in React, Next.js, or vanilla JS
  • ✅ Small, dependency-light footprint
npm install local-storage-typed zod
import { z } from "zod"; import { LocalStorageTyped } from "local-storage-typed"; const store = new LocalStorageTyped({ user: z.object({ id: z.string(), name: z.string(), email: z.string().email(), }), theme: z.enum(["light", "dark"]), }); // Save data store.set("user", { id: "123", name: "Alice", email: "[email protected]", }); // Read data (typed!) const user = store.get("user"); console.log(user?.name); // "Alice" // Remove store.remove("user"); // Clear all schema-defined keys store.clear();
