redux

A json-render screen normally keeps its own data. This makes it use your app's Redux store instead, so there is one set of data rather than two copies that can drift apart.

WHEN TO USE

SCOPE

USE FOR

Back a json-render app's state with an existing Redux Toolkit slice instead of the default store.
Select just the UI slice of a larger Redux state tree for json-render to read.

@json-render/redux

Redux adapter for json-render's StateStore interface. Wire a Redux store (or Redux Toolkit slice) as the state backend for json-render.

Installation

npm install @json-render/redux @json-render/core @json-render/react redux
# or with Redux Toolkit (recommended):
npm install @json-render/redux @json-render/core @json-render/react @reduxjs/toolkit

Usage

import { configureStore, createSlice } from "@reduxjs/toolkit";
import { reduxStateStore } from "@json-render/redux";
import { StateProvider } from "@json-render/react";

// 1. Define a slice for json-render state
const uiSlice = createSlice({
  name: "ui",
  initialState: { count: 0 } as Record<string, unknown>,
  reducers: {
    replaceUiState: (_state, action) => action.payload,
  },
});

// 2. Create the Redux store
const reduxStore = configureStore({
  reducer: { ui: uiSlice.reducer },
});

// 3. Create the json-render StateStore adapter
const store = reduxStateStore({
  store: reduxStore,
  selector: (state) => state.ui,
  dispatch: (next, s) => s.dispatch(uiSlice.actions.replaceUiState(next)),
});

// 4. Use it
<StateProvider store={store}>
  {/* json-render reads/writes go through Redux */}
</StateProvider>

API

`reduxStateStore(options)`

Creates a StateStore backed by a Redux store.

Option	Type	Required	Description
`store`	`Store`	Yes	The Redux store instance
`selector`	`(state) => StateModel`	Yes	Select the json-render slice from the Redux state tree. Use `(s) => s` if the entire state is the model.
`dispatch`	`(nextState, store) => void`	Yes	Dispatch an action that replaces the selected slice with the next state

The dispatch callback receives the full next state model and the Redux store.

Local tool required

1 FOR THE AGENT

01
Install the json-render Redux adapter
Run npm install @json-render/redux @json-render/core @json-render/react plus redux or @reduxjs/toolkit so a Redux store can back json-render's state.

Listed as free: Connected services may require an account or charge fees.
Installation: One command — usually under 2 minutes.

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.

Run this outside your AI tool, using Node.js 22.20.0 or newer. Skills CLI 1.7.2 skips skill selection; prompts cancel installation without an interactive terminal. If choosing Project when asked about installation scope, open your project's folder before running this.

Install checklist

Check selected tools if a picker appears; Claude Code may be unchecked under Additional agents. ↑/↓ moves, Space toggles selections, Enter confirms.
Without a tool picker, check Installing to: for your intended tool. Stop if it names a different tool.
If asked, choose Symlink (Recommended) for shared files or Copy to all agents for separate copies; review the summary before confirming installation.
Install the find-skills skill? defaults to Yes, adding another skill for all projects. Choose No if you don't want that extra installation.

Skills CLI 1.7.2 sends install data to skills.sh by default, including the source, skill names, target tools and file details; GitHub sources are reported only when GitHub confirms the repository is public, while other remote sources can also be reported. Confirmed-public GitHub sources also trigger a security-audit request. Before installing, set the environment variable DO_NOT_TRACK=1 or DISABLE_TELEMETRY=1 to disable both.

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

After installing for Claude Code, open it in the installation project if you chose Project; Global makes the skill available across projects on this computer. Once Claude Code loads the skill, its description helps Claude decide when to use it.

If installation created a top-level skills folder that did not exist when your Claude Code session started, run /reload-skills in that session. Run it again after later changes in that folder.
