reactjs - 用于使用react-redux创建react-app的HMR

Question

使用 create-react-app 初始化的应用程序未启用 HMR 。这里有一篇关于如何启用它的博客文章:http://chrisshepherd.me/posts/adding-hot-module-reloading-to-create-react-app

ReactDOM.render(
  <App />,
  rootEl
);

if (module.hot) {
  module.hot.accept('./App', () => {
    const NextApp = require('./App').default;
    ReactDOM.render(
      <NextApp />,
      rootEl
    );
  });
}

我正在尝试做类似的事情，尽管我添加了 redux和react-router-redux混合:

App.js

import React from 'react'
import { Provider } from 'react-redux'
import store from './store/store'
import routes from './routes'

const App = (
  <Provider store={store}>
    { routes }
  </Provider>
);

export default App;

routes.js

import React from 'react';
import { browserHistory, Router, Route } from 'react-router';
import { syncHistoryWithStore } from 'react-router-redux';
import store from '../store/store';
import { AnonymousLayout } from '../layouts';
import { LoginForm } from './Login';

const history = syncHistoryWithStore(browserHistory, store);

export default (
  <Router history={history}>
    <Route path="/" component={AnonymousLayout}>
      <Route path="/login" component={LoginForm} />
    </Route>
  </Router>
);

index.js

import React from 'react'
import ReactDOM from 'react-dom'
import App from './client/App';

const rootEl = document.getElementById('root');

ReactDOM.render(
  App,
  rootEl
);

if (module.hot) {
  module.hot.accept('./client/App', () => {
    const NextApp = './client/App';
    ReactDOM.render(
        <NextApp />,
        rootEl
      );
  });
}

但是，我刚刚收到此错误:

Warning: [react-router] You cannot change <Router routes>; it will be ignored

有什么方法可以将 HMR 侵入这个项目吗？

丹·阿布拉莫夫 posted a solution这适用于我的情况:

index.js

// regular imports
ReactDOM.render(<App /> , document.getElementById('root'))

if (module.hot) {
  module.hot.accept('./App', () => {
    ReactDOM.render(<App />, document.getElementById('root'))
  })
}

store.js

import { createStore } from 'redux'

import rootReducer from './reducers'

const configureStore = () => {
  const store = createStore(rootReducer)

  if (process.env.NODE_ENV !== "production") {
    if (module.hot) {
      module.hot.accept('./reducers', () => {
        store.replaceReducer(rootReducer)
      })
    }
  }

  return store
}

export default configureStore
