[Solved]-Adding react-hot-loader to ejected create-react-app-Reactjs

if (module.hot && process.env.NODE_ENV !== 'production') {
  module.hot.accept('./reducers', () => {
    const nextRootReducer = require('./reducers'); // eslint-disable-line
    store.replaceReducer(nextRootReducer);
  });
}

return store;
