Cookie Choice is a endpoint that serves a JS library for rendering a cookie consent banner. Endpoint is a Cloudflare Worker to take advantage of the geolocation.

Demo

• Live demo: https://pioug.github.io/cookie-choice/example.html
• "Noop" fuction if not in Europe: https://cookie-choice.pioug.workers.dev/cookie-choice.js?privacy-policy-link=https://github.com/pioug/cookie-choice
• Function to render the banner: https://cookie-choice.pioug.workers.dev/cookie-choice.js?privacy-policy-link=https://github.com/pioug/cookie-choice&force=true

Why?

• Low latency thanks to Cloudflare CDN
• Visitor's location provided by Cloudflare (neither IP geolocation service nor browser geolocation API are needed)
• Library served only when cookie consent law applies to visitor's country
• Small overhead when cookie consent is not required

Installation

1. Build the library:

npm ci
npx rollup -c

2. Deploy cloudflare-worker.js to Cloudflare Workers.

Usage

const privacyPolicyLink = "https://my.privacy.policy/";
const force = true;
const {
  renderCookieChoice
} = await import(`https://my.cloudflare.worker/cookie-choice.js?privacy-policy-link=${privacyPolicyLink}&force=${force}`);
renderCookieChoice();
document.body.addEventListener(
  "cookieChoice:accept",
  {
    once: true
  },
  () => {
    console.log("Thanks for the cookies!");
  }
);
