        applicationId: '',
        params: [
          {
            name: 'whitespaceRemoval'
          },
          {
            name: 'charToTernaryOperator'
          }
        ]
      },
      files: [
        {
          expand: true,
          cwd: '/example/src/'
          src: ['foo.js', 'bar.js'],
          dest: '/destination/'
        },
        {
          expand: true,
          cwd: '/otherexample/'
          src: ['foo.js', 'bar.js'],
          dest: '/otherdestination/'
        }
      ]
    }
  },
});

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.

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