@json-render/zustand

Zustand adapter for json-render's

StateStore

interface. Wire a Zustand vanilla store as the state backend for json-render.

Installation

npm install @json-render/zustand @json-render/core @json-render/react zustand

Requires Zustand v5+. Zustand v4 is not supported due to breaking API changes in the vanilla store interface.

Usage

import { createStore } from "zustand/vanilla";
import { zustandStateStore } from "@json-render/zustand";
import { StateProvider } from "@json-render/react";

// 1. Create a Zustand vanilla store
const bearStore = createStore(() => ({
  count: 0,
  name: "Bear",
}));

// 2. Create the json-render StateStore adapter
const store = zustandStateStore({ store: bearStore });

// 3. Use it
<StateProvider store={store}>
  {/* json-render reads/writes go through Zustand */}
</StateProvider>

With a Nested Slice

const appStore = createStore(() => ({
  ui: { count: 0 },
  auth: { token: null },
}));

const store = zustandStateStore({
  store: appStore,
  selector: (s) => s.ui,
  updater: (next, s) => s.setState({ ui: next }),
});
