GDPR Compliant Cookie Consent Banner In JavaScript – GlowCookies


GlowCookies is a plain JavaScript library that displays a customizable, GDPR compliant cookie consent banner and automatically blocks third-party tracking codes (like Google Analytics, Facebook Pixel, etc) if the user rejects cookies.

How to use it:

1. Download the package and place the cookiesGlow.js library at the end of the document.

<link rel="stylesheet" href="/path/to/src/glowCookies.css" />
<script src="/path/to/src/glowCookies.js"></script>

2. Insert your own tracking codes or scripts as follows. The library currently supports Google Analytics, Facebook Pixel, and Hotjar. The first parameter is used to determine the language you wish to use. Available languages: ‘en’, ‘es’, ‘de’, ‘fr’, ‘th’, ‘sk’, or ‘pt_BR’.

glowCookies.start('en', { 
  analytics: 'G-XXX', 
  facebookPixel: 'XXX',
  HotjarTrackingCode: 'xxx',
  customScript: [{ type: 'custom', position: 'body', content: 'console.log('custom script');' }],
  // or 
  customScript: [{ type: 'src', position: 'head', content: '' }]

3. Specify the path to your own policy page. That’s it.

glowCookies.start('en', { 
  policyLink: ''

4. Customize the appearance of the cookie consent banner.

glowCookies.start('en', { 
  style: 1, // 1, 2, 3
  hideAfterClick: true,
  border: 'none', // or 'border'
  position: 'right', // or 'left'
  bannerDescription: 'banner desc',
  bannerLinkText: 'banner link text',
  bannerBackground: '#000',
  bannerColor: '#fafafa',
  bannerHeading: '<h2>Cookies</h2>',
  acceptBtnText: 'accept btn text',
  acceptBtnColor: 'green',
  acceptBtnBackground: 'red',
  rejectBtnText: 'reject btn text',
  rejectBtnBackground: 'lightblue',
  rejectBtnColor: 'blue',
  manageColor: 'white',
  manageBackground: 'blue',
  manageText: 'cookies text'
