我的webpack.config.js没有反应输出

Question

我的配置出了什么问题，它为index.html提供了没有反应输出的功能。使用这个工具几周，有没有更简单的方法呢？

const path = require('path');
const webpack = require('webpack');

module.exports = {
entry:[
'webpack-dev-server/client?http://localhost:8080',
'webpack/hot/dev-server',
 './src/index.js'
 ],
 output: {
 filename: 'bundle.js',
 path: path.resolve(__dirname, 'dist'),

 },
 module: {
 loaders: [{
    test: /\.jsx?$/,
    exclude: /node_modules/,
    loader: 'babel-loader',
    query:
    {
        presets:['es2015', 'react']
    }
  }]
 },
resolve:{
extensions :['.js','.jsx']
},plugins: [
new webpack.HotModuleReplacementPlugin()
],
devServer: {
contentBase:'./dist/',
compress: true,
hotOnly: true

}

};
