如何用redux和react-router组织状态？

Question

Redux主张使用单一商店的单一商店.但是,使用react-router,您可以获得多个页面,每个页面都有自己的顶级根组件.

应该如何使用具有多个页面的react-router应用程序连接redux？React-router 1.0不再允许您将props传递给路由,因此使路由器成为包含所有页面状态的顶级组件不再可行,也不可行.

如果您正在使用redux + react-router,我强烈建议您使用redux-router - 这将允许您在商店中保留路由信息 - 我通常会进行以下设置.

redux-router:^ 1.0.0-beta3 / react-router":^ 1.0.0-rc1 / redux:"^ 3.0.2/ react:"^ 0.14.0

//index.js [切入点]

import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route } from 'react-router';
import { Provider } from 'react-redux';
import createStore from './utils/create-store';
import routes from './bootstrap/routes';
import { ReduxRouter } from 'redux-router';

const store = createStore(routes);

ReactDOM.render(
    <Provider store={store}>
        <ReduxRouter>
            {routes}
        </ReduxRouter>
    </Provider>,
    document.getElementById('root')
);

// create-store.js

import { applyMiddleware, createStore, combineReducers, compose } from 'redux';
import * as reducers from '../reducers/index';
import promiseMiddleware from './promise-middleware';
import { routerStateReducer, reduxReactRouter } from 'redux-router';
import history from './history'

/**
 * Sets up the redux store.  Responsible for loading up the reducers and middleware.
 *
 * @param routes
 */
export default function create(routes) {
    const composedReducers = combineReducers({
        router: routerStateReducer,
        ...reducers
    });
    const finalCreateStore = compose(applyMiddleware(promiseMiddleware),
        reduxReactRouter({
            routes,
            history
        }))(createStore);
    let store = finalCreateStore(composedReducers);
    return store;
}

// routes.js

import React from 'react';
import { Route } from 'react-router';
import  App from './app';

module.exports = (
    <Route component={App}>
        ...all your routes go here
    </Route>
);

// app.js

import React, { PropTypes } from 'react';
import { connect } from 'react-redux';

export default class App extends React.Component {

    render() {
        const { props: { children } } = this;
        return (
            <div className="app-container">
              {children}
            </div>
        );
    }
}

因此,您可以看到有一个更高阶的组件包装了其余的路由
