js文件加密

加密脚本

const JavaScriptObfuscator = require('javascript-obfuscator');
const fs = require('fs');

let inputContent = '';
try {
  console.log('read file...');
  inputContent = fs.readFileSync('./index.js', 'utf8');
  console.log('read file success');
} catch (err) {
  console.error(err);
  process.exit(1);
}

console.log('obfuscating...');

tips

使用前需要修改脚本输入和输出位置
