Webpack dev服务器不会自动重新加载

Question

所以我设置了webpack webpack-dev-server,但是webpack-dev-server没有自动重新加载.如果我修改文件并保存它,那么在我手动刷新之前,浏览器没有任何变化.

这是我的webpack配置和运行的脚本文件webpack-dev-server.有没有人看到任何可能阻止自动重载工作的东西？

我通过阅读多个教程,文档和阅读react-create-app生成的文件将这些放在一起.

配置/ webpack.config.dev.js

'use strict';

const ExtractTextPlugin = require('extract-text-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const autoprefixer = require('autoprefixer');
const webpack = require('webpack');

const extractSass = new ExtractTextPlugin('style.css');

module.exports = {
    entry : './src/index.jsx',
    eslint: {configFile: './src/.eslintrc.json'},
    module: {
        loaders: [
            {
                exclude: /node_modules/,
                include: ['src'],
                loader: 'babel',
                test  : /(\.js|\.jsx)$/
            },
            {
                exclude: /node_modules/,
                include: ['src']
                loader : extractSass.extract([ 'css', 'postcss', 'sass' ]),
                test   : /\.scss$/
            }
        ],
        preLoaders: [
            {
                exclude: /node_modules/,
                loader : 'eslint',
                query  : {presets: [ 'react', 'latest' ]},
                test   : /(\.js|\.jsx)$/
            }
        ]
    },
    output: {
        filename  : 'bundle.js',
        path      : 'dist',
        publicPath: '/'
    },
    plugins: [
        extractSass,
        new HtmlWebpackPlugin({
            inject  : true,
            template: paths.appHtml
        }),
        new webpack.HotModuleReplacementPlugin({multistep: true})
    ],
    postcss: () => [
        autoprefixer({
            browsers: [
                '>1%',
                'last 4 versions',
                'Firefox ESR',
                'not ie < 9'
            ]
        })
    ]
};

脚本/ dev.js

跟着跑 $ yarn run dev

'use strict';

const WebpackDevServer = require('webpack-dev-server');
const config           = require('../config/webpack.config.dev.js');
const webpack          = require('webpack');

const compiler = webpack(config);

const server = new WebpackDevServer(compiler, {
    clientLogLevel    : 'warn',
    compress          : true,
    contentBase       : 'public',
    filename          : config.output.filename,
    historyApiFallback: true,
    hot               : true,
    inline            : true,
    lazy              : false,
    noInfo            : true,
    publicPath        : '/',
    quiet             : true,
    stats             : 'errors-only',
    watchOptions      : {
        aggregateTimeout: 300,
        poll            : 1000
    }
});

server.listen(8080, 'localhost', () => {
    console.log('Listening on port 8080');
});

根据webpack dev server 文档，您应该将此入口点添加到 webpack 配置中以支持自动刷新。

config.entry.unshift("webpack-dev-server/client?http://localhost:8080/");
