Redux DevTools Extension must be installed and window.__USE_DEVTOOLS__ = true must be in your app. Preferable at the root.

useReducerDevtools

useReducerDevtools is for using devtools with the useReducer hook.
It takes the result from useReducer, an initial state and an instance name as arguments.

useStateDevtools

useStateDevtools is for using devtools with the useState hook. useStateDevtools takes the result from useState, an initial state and an instance name as arguments.

const stateReducer = useReducer(reducer, initialState)
const countState = useState(initialState)

const [state, dispatch] = useReducerDevtools(
  stateReducer,
  initialState,
  'TODO'
)
const [count, setCount] = useStateDevtools(countState, initialState, 'COUNT')

Example

import React, { useState } from 'react'
import ReactDOM from 'react-dom'
import { useStateDevtools } from './use-devtools'

window.__USE_DEVTOOLS__ = true

export default function App() {
  const initialState = 0
  const countState = useState(initialState)
  const [count, setCount] = useStateDevtools(countState, initialState, 'COUNT')

  function handleDecrement(e) {
    e.preventDefault()
    setCount(count - 1)
  }

  function handleIncrement(e) {
    e.preventDefault()
    setCount(count + 1)
  }

  return (
    <div>
      <div>
        Count is {count} <button onClick={handleDecrement}> - </button>
        <button onClick={handleIncrement}>+</button>
      </div>
    </div>
  )
}

const rootElement = document.getElementById('root')
ReactDOM.render(<App />, rootElement)
