如何用 redux 和 react-router 组织状态?
How to organize state with redux and react-router?
Redux提倡使用单一状态的单一商店。然而,使用 react-router 你会得到多个页面,每个页面都有自己的顶级根组件。
应该如何将 redux 与具有多个页面的 react-router 应用连接起来? 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能也不可行。
如果您使用的是 redux + react-router,我强烈建议您也使用 redux-router - 这将允许您在商店中保留路线信息 - 我通常有以下设置。
redux-router: ^1.0.0-beta3 /
反应路由器": ^1.0.0-rc1 /
redux: "^3.0.2/
反应:“^0.14.0
//index.js [入口点]
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')
);
// 创建-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>
);
}
}
正如您所见,有一个高阶组件包裹了其余的路由
Redux-router不再兼容react-router v4,上述方案将无法使用
因此,我建议使用 redux-little-router。与 redux-router 不同,它不依赖于 react-router,而是它的替代品。
有了它,您可以执行以下操作:
从您的异步操作推送到新路由:
export function navigateAbout() {
return (dispatch) => {
dispatch(push('/about'))
}
}
在 redux-dev-tools 中查看你的路由器详细信息(当前路径、查询字符串和参数),并像访问任何其他 prop 一样从你的存储中访问这些详细信息:
function mapStateToProps(state) {
return {
string: state.router.query.string
}
}
PS。可以参考或使用this react boilerplate 已经实现的redux-little-redux
