javascript-obfuscator混淆

安装

npm install javascript-obfuscator -g

配置

重度混淆，性能低

性能下降50-100%

{  
    "compact": true,  
    "controlFlowFlattening": true,  
    "controlFlowFlatteningThreshold": 0.75, // 设置为0到1之间的值  
    "deadCodeInjection": true,  
    "deadCodeInjectionThreshold": 0.4, // 设置为0到1之间的值  
    "debugProtection": true,  
    "debugProtectionInterval": 1000, // 设置为一个正整数，表示毫秒数

    "simplify": true,  
    "splitStrings": false,  
    "stringArray": true,  
    "stringArrayEncoding": [], // 你可以根据需要添加支持的编码算法，如 ["base64", "rc4"]  
    "stringArrayIndexShift": true,  
    "stringArrayWrappersCount": 1,
