Obfuscate JavaScript files via javascriptobfuscator.com.
IMPORTANT: It is possible that your code can be viewed and/or stored by javascriptobfuscator.com. Please DO NOT include any sensitive data. If you care about your code, split and uglify them before obfuscating.
You can install it globally as a command:
npm install -g js-obfuscator
echo "var fs = require('fs')" | jsobfuscate -o keepIndentations=false
var _0x40c7=["\x66\x73"];var fs=require(_0x40c7[0]);
Or install it as a dependency:
npm install js-obfuscator --save
var jsObfuscator = require('js-obfuscator');
jsObfuscator ( <string> input [, <object> options ] )
Returns: a Q promise.
Or you can use it with Grunt ~0.4.0:
If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
npm install js-obfuscator --save-devOnce the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
