How to compress js code in vscode

vscode压缩js代码的方法：

1、在拓展商店里搜索“minify”，安装，安装成功后点重新加载

2、使用：F1运行文件缩小器Minify压缩js代码。

使用Minify的方法介绍：

缩小您的js，css和html文件以节省传输带宽。直接调用每个缩小器，以允许传递设置：

JS： uglify -js v2.7.4

CSS： clean-css v3.4.21

HTML： html-minifier v3.2.2

使用F1 运行文件缩小器Minify。

包含Javascript和CSS文件的文件夹可以{dirname}.min.[css|js]使用F1 缩小为一个文件Minify Directory。可以为Javascript和CSS减少一个目录是可以接受的。

（可选）在已存在匹配的缩小文件（和/或目录）时，在保存时运行minify。启用您的用户或工作空间设置。设置默认值如下所示：

minifiy.css.root接受“ ${workspaceRoot}/ some / path”定义内部@import绝对根。

由于html-minifier还采用了clean-css和uglify-js，设置minifyJS或minifyCSS以true意志嵌入你为那些minifiers自动提供的设置。如果要使用一些其他方法，可以提供自己的设置作为对象。
