响应Redux路由器错误

Question

我正在尝试安装一个Redux + React路由器应用程序。我认为问题在于ImmutableJS，但我不知道如何解决它。

client.js

import { fromJS } from 'immutable'
import React from 'react'
import { render, unmountComponentAtNode } from 'react-dom'
import { AppContainer } from 'react-hot-loader'

import { Provider } from 'react-redux'
import { match, Router, browserHistory } from 'react-router'
import { syncHistoryWithStore } from 'react-router-redux'

import { createStore, combineReducers, compose, applyMiddleware } from 'redux'
import { routerReducer, routerMiddleware } from 'react-router-redux'

function createSelectLocationState(reducerName) {
  let prevRoutingState;
  let prevRoutingStateJS;

  return (state) => {
    const routingState = state.get(reducerName); // or state.routing

    if (!routingState.equals(prevRoutingState)) {
      prevRoutingState = routingState;
      prevRoutingStateJS = routingState.toJS();
    }

    return prevRoutingStateJS;
  };
}

function configureStore(history, initialState) {
  const reducer = combineReducers({
    routing: routerReducer
  });

  return createStore(
    reducer,
    initialState,
    compose(
      applyMiddleware(
        routerMiddleware(history)
      )
    )
  );
}

const initialState = fromJS(window.__INITIAL_STATE__);
const store = configureStore(browserHistory, initialState);
const history = syncHistoryWithStore(browserHistory, store, {
  selectLocationState: createSelectLocationState('routing')
});
const rootNode = document.getElementById('root');

const renderApp = () => {
  const routes = require('./routes');

  match({ history, routes }, (error, redirectLocation, renderProps) => {
    render(
      <AppContainer>
        <Provider store={store}>
          <Router {...renderProps} />
        </Provider>
      </AppContainer>,
      rootNode
    );
  });
};

// Enable hot reload by react-hot-loader
if (module.hot) {
  const reRenderApp = () => {
    try {
      renderApp();
    } catch (error) {
      const RedBox = require('redbox-react').default;

      render(<RedBox error={error} />, rootNode);
    }
  };

  module.hot.accept('./routes', () => {
    setImmediate(() => {
      // Preventing the hot reloading error from react-router
      unmountComponentAtNode(rootNode);
      reRenderApp();
    });
  });
}

renderApp();

我知道这个错误：

Uncaught : state.get不是函数

​

在state中，这个对象

我用"react": "^15.3.2"，"redux": "^3.6.0"，"react-router": "^3.0.0"

更新1我现在使用来自redux-immutable的combineReducers

import {combineReducers} from 'redux-immutable'

但是得到一个错误：

Uncaught : routingState.equals不是函数

在此：

我修正了上面的问题，但是还有一个错误

我在这存储库中发布的所有代码

Answer 1

问题仍然存在于src/index.js文件和route.js的require语句中。

当您使用具有require es6模块的default时，您必须使用required模块中的默认值。就像，

const routes = require('./routes').default;

这解决了你的问题，没有任何其他改变你的git回购。

Answer 2

您使用的combineReducers不使用immutable。通过设置immutable，每个分支都是fromJS(blah)，但不是在状态的最高级别上。使用redux-immutable代替：

import {combineReducers} from 'redux-immutable';
