What is Redux DevTools?

Redux DevTools is a live-editing time travel environment for Redux with hot reloading, action replay, and customizable UI. If you don't want to bother with installing Redux DevTools and integrating it into your project, consider using Redux DevTools Extension for Chrome and Firefox.

Practical Code Example

// Redux DevTools: Chrome extension for state inspection, action history, and time-travel replay:
import { configureStore } from '@reduxjs/toolkit';

const store = configureStore({
  reducer: rootReducer,
  devTools: process.env.NODE_ENV !== 'production' // Enabled automatically in dev!
});
