官网：
https://www.npmjs.com/package/javascript-obfuscator

民间安装方式

npm init -f
npm install formidable --save
npm install -g javascript-obfuscator

官网安装方式

npm install --save-dev javascript-obfuscator

默认不用参数的加密直接执行也可以

javascript-obfuscator input.js --output output.js

---

使用部分自定义参数

--target 'browser-no-eval'
--disable-console-output true
--debug-protection true
--debug-protection-interval true
--identifier-names-generator 'hexadecimal'
--string-array true
--rotate-string-array true
--string-array-encoding 'rc4'
--string-array-threshold 0.8

更多的详细配置参数可以看官网

javascript-obfuscator 1.js --output 2.js --compact true --target 'browser-no-eval' --disable-console-output true --debug-protection true --debug-protection-interval true --identifier-names-generator 'hexadecimal' --string-array true --rotate-string-array true --string-array-encoding 'rc4' --string-array-threshold 0.8

官方推荐的三种配置

1.性能将比没有混淆的情况下慢50-100%

{
    compact: true,
    controlFlowFlattening: true,
    controlFlowFlatteningThreshold: 1,
    deadCodeInjection: true,
    deadCodeInjectionThreshold: 1,
    debugProtection: true,
    debugProtectionInterval: true,
    disableConsoleOutput: true,
    identifierNamesGenerator: 'hexadecimal',
    log: false,
    renameGlobals: false,
    rotateStringArray: true,
    selfDefending: true,
    stringArray: true,
    stringArrayEncoding: 'rc4',
    stringArrayThreshold: 1,
    transformObjectKeys: true,
    unicodeEscapeSequence: false
}

2.性能将比没有混淆的情况下降低30-35%

{
    compact: true,
    controlFlowFlattening: true,
    controlFlowFlatteningThreshold: 0.75,
    deadCodeInjection: true,
    deadCodeInjectionThreshold: 0.4,
    debugProtection: false,
    debugProtectionInterval: false,
    disableConsoleOutput: true,
    identifierNamesGenerator: 'hexadecimal',
    log: false,
    renameGlobals: false,
    rotateStringArray: true,
    selfDefending: true,
    stringArray: true,
    stringArrayEncoding: 'base64',
    stringArrayThreshold: 0.75,
    transformObjectKeys: true,
    unicodeEscapeSequence: false
}

3.性能会比没有混淆的情况稍微慢一些

{
    compact: true,
    controlFlowFlattening: false,
    deadCodeInjection: false,
    debugProtection: false,
    debugProtectionInterval: false,
    disableConsoleOutput: true,
    identifierNamesGenerator: 'hexadecimal',
    log: false,
    renameGlobals: false,
    rotateStringArray: true,
    selfDefending: true,
    stringArray: true,
    stringArrayEncoding: false,
    stringArrayThreshold: 0.75,
    unicodeEscapeSequence: false
}
