我使用Webpack bundler和Webpack dev服务器进行本地开发。前端位于React.js + Redux中，后端位于Node.js和koajs中。Webpack dev服务器抛出错误 - 拒绝执行脚本，因为它的MIME类型（'text/html'）不可执行
在后端，我使用passportjs库进行用户认证和其他库koa-passport，passport-facebook，passport-google-auth通过Facebook或谷歌认证。基本上，我实施了koa-passport-example。
如果我的应用程序需要用户重定向到Facebook或谷歌登录页面，的WebPack开发服务器抛出错误：
GET http://localhost:8090/auth/bundle.js net::ERR_ABORTED
Refused to execute script from 'http://localhost:8090/auth/bundle.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.
如果我用的WebPack生成包，并将其驻留的Node.js服务器上，我不得到这个错误。我需要找出如何设置Webpack dev服务器来摆脱此错误消息。

展望的WebPack进一步，我们应该清楚什么是的WebPack并且它的用途。 Webpack是前端工具，它将构建前端项目，并具有管理类似gulp/grunt的任务的能力。它可以是服务器来提供静态内容。但它不是一个完整的后端服务器。您无法轻松构建后端API并管理复杂的路由。这包括登录功能等。使用Webpack作为开发工具来轻松修改并查看网页设计的更新结果，而不是重新发明轮子。如果您需要更多的功能，通过在监视模式下运行它并集成Webpack并同时运行后端服务器并设置代理，以便Webpack将推迟到后端服务器进行复杂的路由。您可以使用任何后端技术，尽管Webpack建立在Common.js库上，因此将它集成到node.js和express中似乎是最简单的，因为它们是javascript生态系统的一部分。
如果我可以发表评论我会，无论如何，我正在阅读DevServer的webpack文档，我认为服务器正在响应不正确的MIME类型，可能是因为它没有找到它的bundle.js脚本期待着它。我注意到控制台输出是'http://localhost:8090/auth/bundle.js'，在开发文档中，dev服务器期望它在根目录下。我认为，如果bundle.js真的在auth目录中，您可能需要通过publicPath选项告诉服务器它在哪里。
output: {
filename: 'bundle.js',
sourceMapFilename: '[file].map',
path: path.resolve('build/js/),// moves the bundle.js out of the root
publicPath: '/auth/' // it is recommended that the publicPath is declared in both output and devServer
// publicPath links the path of bundle.js to this path in the html.
},
devServer: {
contentBase: path.resolve(__dirname), // New
historyApiFallback: true,
publicPath: "/auth/" // Both publicPath options should be the same as what is in your html loading the scripts
},
据我了解webpack开发服务器，bundle.js不写入光盘。它几乎服务。
现在，所有这些都需要代理已经构建的node.js服务器或构建一个来处理您需要使用的api。 Webpack提供了一个开发中间件模块，用作基本node.js express服务器中的中间件。你可以看到中间件的基础知识here。你真正需要开始从文档通过NPM的WebPack-DEV-中间件安装和表达
npm install --save-dev webpack-dev-middleware express
然后在项目的根目录创建一个类似index.js一个新的服务器文件，因为你已经有了一个server.js。现在只需要处理api调用所需的路由和软件包即可创建所需的基本服务器。
const express = require('express');
const webpack = require('webpack');
const webpackDevMiddleware = require('webpack-dev-middleware');
const app = express();
const config = require('./webpack.config.js');
const compiler = webpack(config);
// Tell express to use the webpack-dev-middleware and use the webpack.config.js
// configuration file as a base.
app.use(webpackDevMiddleware(compiler, {
publicPath: config.output.publicPath
}));
// Serve the files on port 3000.
app.listen(3000, function() {
console.log('Example app listening on port 3000!\n');
});
这是从webpack网站，你需要做你自己的api路由。你会像正常的节点项目一样运行项目，它应该处理bundle.js请求。
我们不要忘记，有一个卡奥koa-webpack-dev plubin。我没有亲自使用koa，但如果你需要它，你可以看到如何使用它here。
