Jotai adapter for json-render's StateStore interface. Use when integrating json-render with Jotai for state management via @json-render/jotai.

AI-generated overview

Documents the @json-render/jotai adapter that backs json-render's StateStore interface with a Jotai atom.

What it does: This skill explains how to wire a Jotai atom as the state backend for json-render through the @json-render/jotai package. It covers installation, basic usage with StateProvider, sharing a custom Jotai store via Provider, and the jotaiStateStore options (atom and store). It produces integration guidance and code examples rather than runnable scripts.
When to use it: Use it when integrating json-render with Jotai for state management, or when json-render and existing Jotai components need to share the same state. It is also useful as a reference for the jotaiStateStore API.
Requirements: Requires the npm packages @json-render/jotai, @json-render/core, @json-render/react and jotai, plus a React/TSX environment. No scripts ship with the skill; it is instructions only.

@json-render/jotai

Jotai adapter for json-render's StateStore interface. Wire a Jotai atom as the state backend for json-render.

Installation

Usage

tsx

import { atom } from "jotai";import { jotaiStateStore } from "@json-render/jotai";import { StateProvider } from "@json-render/react";
// 1. Create an atom that holds the json-render stateconst uiAtom = atom<Record<string, unknown>>({ count: 0 });
// 2. Create the json-render StateStore adapterconst store = jotaiStateStore({ atom: uiAtom });
// 3. Use it<StateProvider store={store}>  {/* json-render reads/writes go through Jotai */}</StateProvider>

import { atom } from "jotai";import { jotaiStateStore } from "@json-render/jotai";import { StateProvider } from "@json-render/react";
// 1. Create an atom that holds the json-render stateconst uiAtom = atom<Record<string, unknown>>({ count: 0 });
// 2. Create the json-render StateStore adapterconst store = jotaiStateStore({ atom: uiAtom });
// 3. Use it<StateProvider store={store}>  {/* json-render reads/writes go through Jotai */}</StateProvider>

With a Shared Jotai Store

When your app already uses a Jotai <Provider> with a custom store, pass it so both json-render and your components share the same state:

tsx

import { atom, createStore } from "jotai";import { Provider as JotaiProvider } from "jotai/react";import { jotaiStateStore } from "@json-render/jotai";import { StateProvider } from "@json-render/react";
const jStore = createStore();const uiAtom = atom<Record<string, unknown>>({ count: 0 });
const store = jotaiStateStore({ atom: uiAtom, store: jStore });
<JotaiProvider store={jStore}>  <StateProvider store={store}>    {/* Both json-render and useAtom() see the same state */}  </StateProvider></JotaiProvider>

import { atom, createStore } from "jotai";import { Provider as JotaiProvider } from "jotai/react";import { jotaiStateStore } from "@json-render/jotai";import { StateProvider } from "@json-render/react";
const jStore = createStore();const uiAtom = atom<Record<string, unknown>>({ count: 0 });
const store = jotaiStateStore({ atom: uiAtom, store: jStore });
<JotaiProvider store={jStore}>  <StateProvider store={store}>    {/* Both json-render and useAtom() see the same state */}  </StateProvider></JotaiProvider>
