Some simple hot reloading

modulehot.js

if (module.hot) {
  module.hot.accept('./components/root/RootComponent.js', () => {
    const FdyRootComponent = require('./components/root/RootComponent.js').FdyRootComponent

    ReactDOM.unmountComponentAtNode(node)
    ReactDOM.render(
      <Provider store={store}>
        <RouterProvider router={router.routerInstance}>
          <FdyRootComponent />
        </RouterProvider>
      </Provider>,
      node)
  })
}
