DISCLAIMER: If you are looking for Jscrambler 3.8 or below please go to this page.

How to Use


Install the Jscrambler webpack loader.

npm install -D jscrambler-loader

Option -D will make sure it is installed as a devDependency.

Setup your .jscramblerrc config file

In order to start using jscrambler-loader you will need to setup your configuration file named .jscramblerrc. This file will contain all the necessary options for your application protection.

You may put your config file in one of these directories.

Here's an example of how your .jscramblerrc file should look like:

// .jscramblerrc
  "keys": {
    "accessKey": "XXXXXX",
    "secretKey": "XXXXXX"
  "applicationId": "XXXXXXXXXXXX",
  "params": [
      "name": "whitespaceRemoval"
      "name": "charToTernaryOperator"

You will need your credentials and Application ID in order to protect your application. Navigate to your profile page and grab your accessKey and secretKey at the API Credentials section.

Your applicationId can be found inside your application page just below your application name. Click the copy to clipboard icon to copy the applicationId.


You can also grab your current configuration on your application page. This will download a .json file containing a valid configuration with your currently selected options.

download config file location

Keep in mind that the params object is optional and if it is not provided we will use your previous configuration.

Webpack Config

This is a simple example on how to add jscrambler-loader to your webpack configuration:

// webpack.config.js
module.exports = {
  entry: './index.js',
  output: {
    filename: 'bundle.js'
  module: {
    loaders: [
       test: /\.js$/,
       exclude: /node_modules/,
       loader: 'jscrambler-loader'

This will use your .jscramblerrc as your Jscrambler protection configuration.
