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：

"minify.minifyExistingOnSave": false,"minify.js": { "mangle": true, "compress": { "sequences": true, "properties": true, "dead_code": true, "drop_debugger": true, "unsafe": false, "unsafe_comps": false, "conditionals": true, "comparisons": true, "evaluate": true, "booleans": true, "loops": true, "unused": true, "hoist_funs": true, "keep_fargs": true, "keep_fnames": false, "hoist_vars": false, "if_return": true, "join_vars": true, "collapse_vars": false, "reduce_vars": false, "side_effects": true, "pure_getters": false, "pure_funcs": null, "negate_iife": false, "drop_console": false, "passes": 1, "global_defs": {} }, "output": { "ascii_only": false, "inline_script": false, "max_line_len": 32000, "braces": false, "semicolons": true, "comments": false, "shebang": true, "preamble": null, "quote_style": "best" }},"minify.css": { "advanced": true, "aggressiveMerging": true, "compatibility": "*", "inliner": {}, "keepBreaks": false, "keepSpecialComments": "*", "mediaMerging": true, "processImport": true, "processImportFrom": ["all"], "rebase": true, "restructuring": true, "root": "${workspaceRoot}", "roundingPrecision": 2, "semanticMerging": false, "shorthandCompacting": true},"minify.html": { "caseSensitive": false, "collapseBooleanAttributes": true, "collapseWhitespace": true, "conservativeCollapse": false, "customAttrAssign": [], "customAttrCollapse": "", "customAttrSurround": [], "customEventAttributes": [ "^on[a-z]{3,}$" ], "decodeEntities": false, "html5": true, "ignoreCustomComments": [ "^!" ], "ignoreCustomFragments": ["<%[\\s\\S]*?%>", "<\\?[\\s\\S]*?\\?>"], "includeAutoGeneratedTags": true, "keepClosingSlash": false, "maxLineLength": false, "minifyCSS": true, //uses minify.css settings if true "minifyJS": true, //uses minify.js settings if true "minifyURLs": false, "preserveLineBreaks": false, "preventAttributesEscaping": false, "processConditionalComments": false, "processScripts": [], "quoteCharacter": "\"", "removeAttributeQuotes": false, "removeComments": false, "removeEmptyAttributes": false, "removeEmptyElements": false, "removeOptionalTags": false, "removeRedundantAttributes": false, "removeScriptTypeAttributes": false, "removeStyleLinkTypeAttributes": false, "sortAttributes": false, "sortClassName": false, "useShortDoctype": false}

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。
