# Blink Features JS Check - Do not use Chromium’s experimental features

The blinkFeatures / enableBlinkFeatures flag can be used to selectively enable Blink (Chromium web browser engine) features, which increases the overall attack surface for production applications.

#Risk

Experimental features may introduce bugs and increase the attack surface of the application.

#Auditing

Search for blinkFeatures / enableBlinkFeatures flags set to true within the webPreferences of BrowserWindow:

        mainWindow = new BrowserWindow({
  webPreferences: {
    enableBlinkFeatures: 'CSSVariables'
  }
});
