#JavaScript obfuscator for Node.js

JavaScript obfuscator for Node.js and free alternative of js-obfuscator (which uses javascriptobfuscator.com) without any limits and sending data on server. Compatible with ES6. Tested on Angular2 bundle. https://gist.github.com/sanex3339/ffc2876123b52e6d11ce45369fd53acf

##Important: right now obfuscation of code which was minimized with UglifyJS may not work (tested on Angular 2 bundle). I will try to fix that soon or later.

###Installation

Install the package with NPM and add it to your devDependencies:

npm install --save-dev javascript-obfuscator

###Usage:

var JavaScriptObfuscator = require('javascript-obfuscator');

var obfuscatedCode = JavaScriptObfuscator.obfuscate(
    `
    (function(){
        var variable = 'abc';
        console.log(variable);
    })();
    `,
    {
        rotateUnicodeArray: false
    }
);

console.log(obfuscatedCode);
/*
var _0x8741 = [
    '\u0061\u0062\u0063',
    '\u006c\u006f\u0067'
];
(function () {
    var _0x45e59c = _0x8741[0];
    console[_0x8741[1]](_0x45e59c);
}());
*/

obfuscate(sourceCode, options)

###sourceCode Type: string Default: null

Any valid SourceCode

###options Type: Object Default: null

Options for JavaScript obfuscator:

{
    rotateUnicodeArray: false
}

###Available options ####rotateUnicodeArray Type: boolean Default: true

For more hard understanding of code, during each obfuscation all literal values are stored in array as Unicode codes sequence. This options will rotate all values inside array on a random value during obfuscation of code, and insert inside source code helper function which will rotate array values back to their original indexes.

This option affected only on visual code organisation, because we can easily get original array during debug process.

Not recommended for small source code, because helper function will attract attention.
