API Reference

@json-render/zustand

Zustand adapter for json-render's StateStore interface.

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

Installation

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

zustandStateStore

Create a StateStore backed by a Zustand vanilla store.

import { zustandStateStore } from "@json-render/zustand";

Options

Option	Type	Required	Description
`store`	`StoreApi<S>`	Yes	A Zustand vanilla store (from `createStore` in `zustand/vanilla`).
`selector`	`(state: S) => StateModel`	No	Select the json-render slice from the store state. Defaults to the entire state.
`updater`	`(nextState: StateModel, store: StoreApi<S>) => void`	No	Apply a state change back to the store. Defaults to a shallow merge.

Example

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

const bearStore = createStore(() => ({
  count: 0,
  name: "Bear",
}));

const store = zustandStateStore({ store: bearStore });

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

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 }),
});
