Simple-Node-Obfuscator

What it is:

A simple wrapper around the javascript-obfuscator npm pacakge that will include and produce complete code file structre.

What it is not:

Some kind of magical obfuscator package built from scratch. The main goal for this module is to provide the same file structre for your obfuscated code.

source -> src/server/server.js
compiled -> dist/server/server.js

This also works for multiple file layers such as src/**/**/**/**/*.js.

Example:

const Compile = require("simple-node-obfuscator");
const path = require("path");

const options = {
  compact: true,
  controlFlowFlattening: true,
  controlFlowFlatteningThreshold: 1,
  numbersToExpressions: true,
  simplify: false,
  stringArrayShuffle: true,
  splitStrings: true,
  stringArrayThreshold: 1,
};

Compile("files/**/**/**/*.js", "dist", "files", options);

Function:

Compile(src, dst, mainDirectory, options) => void

src -> Source directory for the JavaScript files > "src/**/**/*.js"
dst -> Destination directory for the JavaScript files > "dist"
mainDirectory -> Name of the main directory for the JavaScript files > default "src"
options -> These Options are for javascript-obfuscator npm package, you can find all the options available here: https://www.npmjs.com/package/javascript-obfuscator

Output:

Example of a simple Express app.

const express = require("express");
const app = express();

app.get("/", (req, res) => {
  return res.status(200).send("Hello, World!");
});

app.listen(3000, () => "Express running on port 3000");

Produces the following.

(function (_0x14af18, _0x500824) {
  const _0x5d622a = _0x4cd0;
