+# Zustand Sync Tabs [![Version](https://img.shields.io/npm/v/zustand-sync.svg?colorB=green)](https://www.npmjs.com/package/zustand-sync) [![Downloads](https://img.jsdelivr.com/img.shields.io/npm/dt/zustand-sync.svg)](https://www.npmjs.com/package/zustand-sync) ![npm bundle size](https://img.shields.io/bundlephobia/minzip/zustand-sync)

+> Zustand middleware to easily persist and sync Zustand state between tabs / windows / iframes (SameOrigin)
+
+> Motivation: Recently I got cought up in several issues working with persist miggleware and syncing tabs with zustand. This is a simple light weight middleware to persist and instantly share state between tabs or windows
+
+- ✅ 🐙 (495 Bytes gZiped) < 0.5 kB size cross-tab state sharing middleware for zustand
+- ✅ Full TypeScript Support
+- ✅ solid reliability in 1 writing and n reading tab-scenarios (with changing writing tab)
+- ✅ Fire and forget approach of always using the latest state. Perfect for single user systems
+- ✅ Sync Zustand state between multiple browsing contexts
+
+> Checkout `[persistnsync](https://github.com/mayank1513/nextjs-themes/tree/main/packages/persistnsync#readme)` if you are looking for persisting state locally over reload/refresh or after closing site
+
+## Install
+
+```bash
+$ pnpm add zustand-sync
+# or
+$ npm install zustand-sync
+# or
+$ yarn add zustand-sync
+```
+
+## Usage
+
+Simply add the middleware while creating the store and the rest will be taken care.
+
+```ts
+import { create } from "zustand";
+import { syncTabs } from "zustand-sync";
+
+type MyStore = {
+  count: number;
+  set: (n: number) => void;
+};
+
+const useStore = create<MyStore>(
+  syncTabs(
+    set => ({
+      count: 0,
+      set: n => set({ count: n }),
+    }),
+    { name: "my-channel" },
+  ),
+);
+```
+
+⚡🎉Boom! Just a couple of lines and your state perfectly syncs between tabs/windows and it is also persisted using `localStorage`!
