按住shift鍵，單擊鼠標右鍵，選擇打開如下圖所示的命令窗口。
2.打開窗口，直接在窗口中執行。
醜八怪？main.js？demo.js？-哦？foo.min.js？-來源-地圖？foo.min.js.map？- source-map-root？http://onbook.me？-p？5?-c？-m？-包裝？- export-all混淆文件main.js和demo.js生成foo.min.js和foo.min.js.map並指定地圖的來源網站。
3.另壹種使用方法是將UglifyJS2包放入程序中，通過API壓縮JS文件或JS代碼。首先，創建壹個新的NPM項目文件package.json，然後下載UglifyJS2依賴包。
創建壹個新文件package.json
{
“姓名”:" nodejs-uglifyjs2 "，
“版本”:"0.0.1",
【描述】:？“醜八怪js2”，
「作者」:？“柯南？張？”,
“依賴關系”:{
}
}4.執行npm install uglify-js - save以下載UglifyJS2依賴包。
5.安裝完成後
創建壹個新的test.js並開始測試。
var？醜八怪？=?require(' uglify-js ')；
//代碼壓縮
var？結果？=?UglifyJS.minify("var？b？=?功能？()?{};",?{fromString:？true })；
console . log(" \ n = = = = = = = = = = = = = = = = = = = = = = = = = ")；
console.log(結果)；
//文件壓縮
結果？=?uglifyjs . minify([" demo . js "])；
console . log(" \ n = = = = = = = = = = = = = = = = = = = = = = = = = ")；
console . log(result . code)；
//多文件壓縮，指定來源？地圖和網站來源
結果？=?UglifyJS.minify(["main.js "，" demo.js"]，{
外包地圖:？" out.js.map "，
sourceRoot:？" http://onbook.me "，
沒錯
});
console . log(" \ n = = = = = = = = = = = = = = = = = = = = = = = = = ")；
console . log(result . code)；
console . log(result . map)；http://blog.fens.me/nodejs-uglifyjs2-js/
