Minify - JS-Confuser

Option name: "minify"
Option values: true/false

Input / Output

This example showcases how Minify transforms the code. Try it out by changing the input code and see changes apply in real-time.

Input.js

// Input.js
var { fullName } = { fullName: 'John Doe' };

console.log(fullName); // "John Doe"

// Output.js
var HtZhTw = 'John Doe';
console.log(HtZhTw);

Minification Techniques

Dead code elimination
Variable grouping
Constant folding
Shorten literals:
- true to !0
- false to !1
- Infinity to 1/0
- undefined to void 0
Remove unused variables and functions
Bracket to dot notation
Remove redundant braces
If statement to ternary operator
Expression consolidation

Usage Example

The provided code example will obfuscate the file input.js and write the output to a file named output.js.

Usage Example

import JSConfuser from "js-confuser";
import {readFileSync, writeFileSync} from "fs";

// Read input code
const sourceCode = readFileSync("input.js", "utf8");
const options = {
  target: 'browser',
  minify: true,
};

JSConfuser.obfuscate(sourceCode, options).then((result)=>{
  // Write output code
  writeFileSync("output.js", result.code);
}).catch(err=>{
  // Error occurred
  console.error(err);  
});
