redux

An adapter that lets json-render use Redux or Redux Toolkit as its state store. Redux is a JavaScript library for keeping application state in one managed store.

In plain words
What is it for?
Use it to connect a Redux store or Redux Toolkit slice to json-render, select the relevant state, and dispatch updates through a StateProvider.
Why use it?
It lets existing Redux state be used by json-render instead of maintaining a separate state system for the rendered interface.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

redux scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

@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.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

redux is a skill published in the GitHub repository vercel-labs/json-render (16,056 stars, last pushed 5d ago), licensed Apache-2.0. It adds 32 tokens to every session and 489 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
