javascript-obfuscator plugin for Webpack which supports sourcemaps

Note

This repo is forked from webpack-obfuscator. A few things have been changed to fix the sourcemap generation which does not work as expected in the original package. Since the obfuscation is done now in the optimizeChunkAssets hook, the selfDefending option may not work.

Installation

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

npm install --save-dev webpack-better-obfuscator

Usage:

var JavaScriptObfuscator = require('webpack-better-obfuscator');

// ...

// webpack plugins array
plugins: [
	new JavaScriptObfuscator ({
      rotateUnicodeArray: true
  }, ['excluded_bundle_name.js'])
],

obfuscatorOptions

Type: Object Default: null

Options for javascript-obfuscator. Should be passed exactly like described on their page.

Warning: right now plugin not supported souceMap and souceMapMode options!

excludes

Type: Array or String Default: []

Bundle name is output file name after webpack compilation. With multiple webpack entries you can set bundle name in output object with aliases [name] or [id].

Syntax for excludes array is syntax for multimatch package. You can see examples on package page.

Few syntax examples: ['excluded_bundle_name.js', '**_bundle_name.js'] or 'excluded_bundle_name.js'

Example:

// webpack.config.js
'use strict';

const JavaScriptObfuscator = require('webpack-better-obfuscator');

module.exports = {
    entry: {
        'abc': './test/input/index.js',
        'cde': './test/input/index1.js'
    },
    output: {
        path: 'dist',
        filename: '[name].js' // output: abc.js, cde.js
    },
    plugins: [
        new JavaScriptObfuscator({
            rotateUnicodeArray: true
        }, ['abc.js'])
    ]
};

Can be used to bypass obfuscation of some files.
