Package Exports

sync-tabs-zustand
sync-tabs-zustand/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (sync-tabs-zustand) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Install

$ pnpm add sync-tabs-zustand
# or

Usage

Simply add the middleware while creating the store and the rest will be taken care.

import { create } from "zustand";
import { syncTabs } from "sync-tabs-zustand";

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!
