webpack(三)---管理输出

1、输出多个 bundle

dist/index.html

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Output Management</title>
  </head>
  <body>
  <script type="text/javascript" src="app.bundle.js"></script><script type="text/javascript" src="print.bundle.js"></script></body>
</html>

webpack.config.js

 entry: {
        app: './src/index.js',
        print: './src/print.js'
    },
    output:{
        filename: '[name].bundle.js',
        path: path.resolve(__dirname, 'dist')
    },
 
2、设定 HtmlWebpackPlugin
npm install --save-dev html-webpack-plugin
然而 HtmlWebpackPlugin  它会用新生成的 index.html 文件,把我们的原来的替换
 
 
webpack.config.js
 const path = require('path');
+ const HtmlWebpackPlugin = require('html-webpack-plugin');

  module.exports = {
    entry: {
      app: './src/index.js',
      print: './src/print.js'
    },
+   plugins: [
+     new HtmlWebpackPlugin({
+       title: 'Output Management'
+     })
+   ],
    output: {
      filename: '[name].bundle.js',
      path: path.resolve(__dirname, 'dist')
    }
  };

3、清理 /dist 文件夹

npm install clean-webpack-plugin --save-dev

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
+ const CleanWebpackPlugin = require('clean-webpack-plugin');

module.exports = {
entry: {
app: './src/index.js',
print: './src/print.js'
},
plugins: [
+ new CleanWebpackPlugin(['dist']),
new HtmlWebpackPlugin({
title: 'Output Management'
})
],
output: {
filename: '[name].bundle.js',
path: path.resolve(__dirname, 'dist')
}
};

这个官网两处有坑:

 

看了一下githup上的写法,现在新版本的clean-webpack-plugin引入已经改为const CleanWebpackPlugin require('clean-webpack-plugin');  更改即可

然后运行npm run build 又报错如下

 

 里面参数去掉即可
new CleanWebpackPlugin()
