注意这个页面中的css,js,img资源,用的是webpack.config.js 的publicPath
module.exports = {
devtool: '#source-map',
entry: entry_files,
output: {
filename: 'static/js/[name][hash].js',
chunkFilename: './static/js/[id].chunk.js',
path: path.join(__dirname, 'dist'),
//publicPath 上线替换真实的http,如果设置为/则需把dist下的文件放在项目的根目录
//publicPath:'http://localhost:3000/'
publicPath:'./'
// 这里的publicPath注意,后来HtmlWebpack插件资源注入页面模板时,是在这个地址下的

utils.js 判断生产环境,开发环境

原来html中没有css,js引入 是统一引入同名资源
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>index</title>
</head>
<body>
<div class="container">
<div class="row">
<div><p>index</p></div>
<div class="col-md-12 tcon">

</div>
<div class="row">
<div class="col-md-6">
<img >
</div>
</div>
</div>
</body>
</html>
