@json-render/jotai

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

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>

How to use it

Copy the folder

Take vercel-labs/jotai from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npm. Without those the skill loads but fails at the first command.
