具有Create-React-App,Express,Redux和React-Router的SSR

我们有一个React App,现在我们想使其成为同构(SSR)。 我们深深地使用Redux。所有的xhr请求都通过Redux动作并保存在reducer上。​​

我对react ssr有疑问。

1。我应该对此流程使用同构提取吗?或者我可以改用axios?

2。在执行动作分派和接收到数据时,server.js中的存储没有更新。我该怎么办?

我们有一些页面希望urlParams调度操作。

这是我们的Express服务器文件:

import cStore from './store'

app.use(express.static(path.resolve(__dirname, "../dist")));
app.use('/public', express.static(path.resolve(__dirname, "../public")));
app.use(cors())
app.get("*", (req, res, next) => {


    
    const store = cStore();

    const context = {};
    const dataRequirements =
        routes
            .filter(route => matchPath(req.url, route)) // filter matching paths
            .map(route => route.component) // map to components
            .filter(comp => comp.fetchMe) // check if components have data requirement
            .map(comp => {
                comp.fetchMe(store, req.params[0])
            }); // dispatch data requirement

如您在上面的片段中看到的,我在每条路由上调度fetchMe操作,并将存储和url发送到映射的组件,并将store.getState()保存在window.REDUX_DATA

这是我的组件fetchMe操作之一:

Tour.fetchMe = (store, obj) => {
    let tourId = obj.split("/").pop() //split last part of url that show me tourId
    store.dispatch(fetchTourData(tourId))
}

这是我的store.js文件,我从那里分发操作,结合了reducer和创建redux存储的cStore函数位于此处:

import { createStore, combineReducers, applyMiddleware } from "redux";
import thunkMiddleware from "redux-thunk";
import { fetchToursIso } from "./store/isomorphic/api";


const storeTourData = (res) => ({
    type: "FETCH_TOUR_FULFILLED",
    payload: res,
});


const tourReducer = (state = [], action) => {
    switch (action.type) {
        case "FETCH_TOUR_FULFILLED":
            return action.data;
        default: return state;
    }
};



export const fetchTourData = (tourId) => (dispatch) => {
    fetchToursIso(tourId).then(res => {
        dispatch(storeTourData(res))
    })
};

const reducer = combineReducers({
    tour: tourReducer,


});

export default (initialState) =>
    createStore(reducer, initialState, applyMiddleware(thunkMiddleware));

此流程正确吗?或者我必须使用另一种方法。

谢谢。
