#git

🧰 Not standalone. This skill ships with vercel-labs/json-render and only works together with that tool — install the tool first, then add this skill.

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.

@json-render/jotai

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

API

`jotaiStateStore(options)`

Creates a StateStore backed by a Jotai atom.

Option	Type	Required	Description
`atom`	`WritableAtom<StateModel, [StateModel], void>`	Yes	A writable atom holding the state model
`store`	Jotai `Store`	No	The Jotai store instance. Defaults to a new store. Pass your own to share state with `<Provider>`.

Copy & paste — that's it

npx skills add vercel-labs/json-render --skill "jotai" --full-depth

Run this in your project — your agent picks the skill up automatically.

Installation

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

Usage

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 state
const uiAtom = atom<Record<string, unknown>>({ count: 0 });

// 2. Create the json-render StateStore adapter
const 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:

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>
