1 copy-webpack-plugin
Copies individual files or entire directories, which already exist, to the build directory
webpack-copy-plugin is not designed to copy files generated from the build process; rather, it is to copy files that already exist in the source tree, as part of the build process.
## copy文件到打包的文件夹当中，只能copy已经存在的文件
2 filemanager-webpack-plugin
This Webpack plugin allows you to copy, archive (.zip/.tar/.tar.gz), move, delete files and directories before and after builds
## 文件管理插件，可以在打包前以及打包后 对所有的文件进行拷贝，压缩，移动，删除等相关操作
3 html-webpack-plugin
This is a webpack plugin that simplifies creation of HTML files to serve your webpack bundles.
## 以一个html文件为模板，生成一个html文件，并将打包生成的js文件注入当中
4 Clean plugin for webpack
By default, this plugin will remove all files inside webpack's output.path directory, as well as all unused webpack assets after every successful rebuild
## 只会移除webpack's output.path directory 目录下的文件，(比如你生成的目录是dist，那么它只会移除dist下面的文件，但是不包含dist本身)
5 webpack.ProvidePlugin
new webpack.ProvidePlugin({
$: 'jquery',
_: 'lodash'
})
## 垫片插件 ，当我们在代码中使用到相关的变量，但是没有引入相关的模块时，该插件会自动帮我们引入
6 add-asset-html-webpack-plugin
After webpack 4+, it is required to apply AddAssetHtmlPlugin after HtmlWebpackPlugin
## 必须要在HtmlWebpackPlugin插件之后使用它，往生成的html文件当中额外插入资源文件
7 webpack.DllReferencePlugin
new webpack.DllReferencePlugin({
manifest: path.resolve(__dirname, './dll', file)
}),
## 当打包第三方模块时，首先会通过这个映射去查找，查看这个模块是否被打包，如果找不到再去node_modules
