Ensuring user privacy and data protection is more important than ever, especially for websites operating within the European Union (EU). The General Data Protection Regulation (GDPR), which came into effect in May 2018, is designed to protect the personal data and privacy of EU citizens.

One of its key components is obtaining user consent before processing their personal information, particularly through cookies that track online behavior. This regulation applies not just to EU-based websites, but to any site that serves EU users, making GDPR compliance a global concern.

Failure to comply with GDPR can result in substantial fines. Depending on the severity of the violation, penalties can range up to 4% of a company’s annual global turnover or €20 million—whichever is higher. Several high-profile cases have resulted in major fines for companies like Google, H&M, and British Airways, underscoring the seriousness of GDPR enforcement.

For websites, this means implementing a clear and accessible cookie consent mechanism is essential. Users should be informed about the types of cookies being used and must be given the option to opt-in or opt-out of non-essential cookies.

In this post, we explore 11 JavaScript libraries that can help you seamlessly integrate GDPR-compliant cookie consent mechanisms, ensuring your website meets regulatory standards while maintaining a smooth user experience.
