React/Express沒有正確地路由鏈接

Question

所以，我有一個反應項目，工作正常，除了快遞。我很難找到MERN堆棧教程正確路由與快速。

我發現了一些SO帖子，但沒有在我的項目中工作。當我將某人快速鏈接到反應路線時，我得到'未找到'。我一直在討論這個公平的問題，因此評論了靜態中間件。

module.exports = app;

import React from 'react'; 
import { Route, Switch } from 'react-router-dom' 
import {Home} from './Home' 
import {NotFound} from './NotFound' 

import {Header} from './Header' 
import {Foot} from './Footer'

API是不相關的..

我該如何解決這個問題？

Answer 1

請確保您所有的文件require()都有modules.export。在這種情況下，將它添加到root.js：通過接受這個作爲答案的努力去

module.exports = router; 

謝謝，這很酷;）

Answer 2

您可以將反應項目添加爲靜態內容來表示應用程序。

app.use(express.static('client/build)); // path must be relative to your express app 

// or if you like to make it work on a sub root 
app.use('/reactapp', express.static('client/build')); 

如果您有創建反應的應用程序內創建你的項目，你應該添加反應項目的package.json文件的代理爲您的明確程序。

{ 
    "proxy": "http://localhost:500" // port can change according to your settings 
} 

有一個詳細的教程here。此外，create-react-app文檔還包含有關使用Node的一些信息。
