Example

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();
