Package Exports

js-obfuscator

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (js-obfuscator) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

js-obfuscator

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-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('js-obfuscator');
