npm install -g code-obfuscator

npm install code-obfuscator
# or
bun add code-obfuscator

git clone https://github.com/openapphub/code-obfuscator.git
cd code-obfuscator
bun install

code-obfuscator --input <input-file> --output <output-file>
# Examples
code-obfuscator --input index.html --output obfuscated.html
code-obfuscator --input script.js --output obfuscated.js
code-obfuscator --input ./src/app.html --output ./dist/app.html

code-obfuscator --input index.html --output dist/index.html

code-obfuscator --input app.js --output dist/app.js

# Process multiple files
for file in *.html; do
 code-obfuscator --input "$file" --output "dist/$file"
done

The tool uses JavaScript Obfuscator with the following protection features:

• ✅ 压缩 (Compaction): Remove unnecessary whitespace and comments
• ✅ 控制流扁平化 (Control Flow Flattening): Transform code structure
• ✅ 死代码注入 (Dead Code Injection): Add meaningless code to confuse analysis
• ✅ 字符串数组 (String Array): Encode strings in arrays with transformations
• ✅ 标识符重命名 (Identifier Renaming): Use hexadecimal names
• ✅ 数字表达式 (Numbers to Expressions): Convert numbers to expressions
• ✅ 字符串分割 (String Splitting): Split strings into chunks
• ✅ 自我保护 (Self-Defending): Prevent code beautification
• ✅ 控制台禁用 (Console Output Disabled): Remove console statements

• ✅ 内联 JavaScript 混淆: Obfuscate <script> tags without src
• ✅ 外部 JavaScript 处理: Process external JS files referenced in HTML
• ✅ HTML 压缩: Minify HTML structure
• ✅ 路径保持: Maintain relative paths for external resources

The obfuscator uses optimized default settings, but you can modify obfuscator.ts for custom configurations:

const jsObfuscatorOptions = {
 compact: true,
 controlFlowFlattening: true,
 deadCodeInjection: true,
 stringArray: true,
 // ... other options
};
