JS Obfuscator Advanced

A modern, advanced JavaScript obfuscation tool built as an ES Module. Transform your JavaScript code to make it harder to reverse-engineer while maintaining functionality.

Features

• Variable renaming with random identifiers
• String encoding using hex transformation
• Control flow flattening
• Dead code injection
• TypeScript and JSX support
• Configurable obfuscation options

Installation

npm install obfuscripter

Usage

import { obfuscate } from 'obfuscripter';

const sourceCode = `
  const greeting = "Hello World";
  let count = 0;
  
  function sayHello(name) {
    if (name) {
      console.log(greeting + " " + name);
    } else {
      console.log("No name provided");
    }
    return count++;
  }
`;

const obfuscated = obfuscate(sourceCode, {
  renameVariables: true,
  encodeStrings: true,
  flattenControlFlow: true,
  injectDeadCode: true
});

console.log(obfuscated);

Options

The obfuscator accepts an optional configuration object with the following properties:

| Option | Type | Default | Description | |--------------------|---------|---------|-----------------------------------| | renameVariables | boolean | true | Rename variables to random IDs | | encodeStrings | boolean | true | Encode string literals to hex | | flattenControlFlow| boolean | true | Flatten if-statements to switches | | injectDeadCode | boolean | true | Add unreachable code blocks |

Example with custom options:

const obfuscated = obfuscate(code, {
  renameVariables: true,
  encodeStrings: false,
  flattenControlFlow: true,
  injectDeadCode: false
});

Requirements

• Node.js 14+ (for ES module support)
• npm 6+

Disclaimer

While this obfuscator makes code harder to read, it is not a foolproof security solution. Obfuscation can be reversed with sufficient effort. Use additional security measures for critical applications.
