为什么React Webpack生产版本显示空白页面？ [英] Why is React Webpack production build showing Blank page?

问题描述

我正在建立一个反应应用程序，目前 webpack-dev-server 工作正常（ hello world 文本显示），但webpack -p显示空白页面。对于生成构建chrome dev工具下的网络选项卡，显示 index.html 和 index_bundle.js ，大小为0 B（见图）但显然不是HTML文件大小为227 B& index_bundle.js 文件大小为195Kb（见图）

I'm building a react app, and at the moment webpack-dev-server works just fine( the hello world text shows up ), But webpack -p shows blank page. For the Production build The network tab under chrome dev tools, shows index.html and index_bundle.js to have size 0 B(see picture) But That is clearly not the case HTML file size is 227 B & index_bundle.js file size is 195Kb(see picture)

Chrome Devtools Elements标签显示以下内容（见图片）

Also Chrome Devtools Elements Tab shows the following(see picture)

我的webpack配置文件如下所示：

My webpack config file looks like this:

推荐答案

我想通了，我在没有设置本地服务器的情况下使用了browserHistory。如果我把它改成hashHistory它就有效了。要使用react-router浏览器历史记录在本地测试webpack生产，我需要这样做配置服务器：

I figured it out, I was using browserHistory without setting up a local server. If i changed it to hashHistory it worked. To test webpack production locally with react-router browser history i needed to do this Configure a Server:

您的服务器必须准备好处理真实的URL。当应用程序首次加载/它可能会工作，但当用户导航，然后在/ accounts / 23点击刷新时，您的Web服务器将收到/ accounts / 23的请求。您将需要它来处理该URL并在响应中包含您的JavaScript应用程序。

Your server must be ready to handle real URLs. When the app first loads at / it will probably work, but as the user navigates around and then hits refresh at /accounts/23 your web server will get a request to /accounts/23. You will need it to handle that URL and include your JavaScript application in the response.

快递应用程序可能如下所示：

An express app might look like this:

const express = require('express')
const path = require('path')
const port = process.env.PORT || 8080
const app = express()

// serve static assets normally
app.use(express.static(__dirname + '/public'))

// handle every other route with index.html, which will contain
// a script tag to your application's JavaScript file(s).
app.get('*', function (request, response){
  response.sendFile(path.resolve(__dirname, 'public', 'index.html'))
})

app.listen(port)
console.log("server started on port " + port)

如果有人使用带有浏览器历史记录的react-router部署到firebase，请执行以下操作：

And just in case anyone is deploying to firebase using react-router with browser-history do this:

{
  "firebase": "<YOUR-FIREBASE-APP>",
  "public": "<YOUR-PUBLIC-DIRECTORY>",
  "ignore": [
    "firebase.json",
    "**/.*",
    "**/node_modules/**"
  ],
  "rewrites": [
    {
      "source": "**",
      "destination": "/index.html"
    }
  ]
}
