Object Extraction - JS-Confuser

Option name: "objectExtraction"
Option values: true/false/0-1/Function

Input / Output

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

Input.js

// Input.js
var utils = {
  isString: (x) => typeof x === 'string',
  isBoolean: (x) => typeof x === 'boolean',
};
if (utils.isString('Hello')) {
  console.log('Correct type'); // "Correct type"
}

// Output.js
var et3UbC = (et3UbC) => {
  return typeof et3UbC === 'string';
};
if (et3UbC('Hello')) {
  console.log('Correct type');
}

Custom Implementation

`options.objectExtraction(objectName)`

Control which objects are changed. Returns a boolean.

Parameter	Type	Description
`objectName`	`string`	The object proposed to be changed.

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',
  objectExtraction: true,
  renameVariables: false,
};

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