Cookie consent

Overview

CookieConsent v3 is a cookie consent plugin written in plain JavaScript. According to its documentation it manages scripts, and therefore cookies, by blocking them until the visitor gives explicit consent, and it integrates into any web platform or framework. The documentation gives examples for HTML, React, Vue and Angular.

The documentation also states its limits: the plugin requires basic JavaScript knowledge, has no default categories or translations, is not a consent management platform (CMP), does not store consent records and does not implement the IAB TCF framework. A playground lets you try the plugin.

Highlights

• A lightweight plugin in plain JavaScript, described in the README as GDPR compliant (the documentation also mentions CCPA).
• Blocks scripts until explicit consent is given and provides opt-out options, according to the documentation.
• Version 3 supports individually togglable services and offers UMD and ESM variants; it targets modern browsers only.
• Three ways to install (npm, CDN, release download) and integration examples for HTML, React, Vue and Angular.
• The documentation states it can be controlled by keyboard and screen readers; a playground and Stackblitz examples are provided.
