persistent-svelte-store

Description

A generic persistent writable store, built from scratch in TypeScript according to the Svelte store contract. Store value is stored in localStorage as a JSON string, but this is transparent to user. The store is reactive across tabs or windows using the Broadcast Channel API.

Example

Create a store and supply a type

stores.ts

import { persistentWritable } from "./persistentStore";
export const store = persistentWritable<object>("storeKey", {});

Use like any writable store

App.svelte

<script lang="ts">
  import { store } from "./stores";
  $store = { id: 1 };
  console.log($store.id);
</script>
