What is a cookie banner javascript?

A cookie banner javascript is a tool that creates cookie consent notices for websites. Under GDPR and similar privacy laws, websites must inform visitors about cookie usage and obtain consent before setting non-essential cookies like analytics or advertising trackers.

TinyConsent's cookie banner javascript provides real script blocking with just one line of code. Unlike complex solutions that require configuration files and npm packages, our approach is simple: paste a script tag, and your consent infrastructure is ready.

Frequently Asked Questions

Does this work with React/Vue/Angular?

Yes. Since it's a simple script tag that loads asynchronously, it works with any JavaScript framework including React, Vue, Angular, Svelte, and Next.js.

How big is the JavaScript file?

The initial loader is under 5KB gzipped. Additional resources load on-demand to keep your page fast.

Does it conflict with other scripts?

No. TinyConsent uses an isolated scope and doesn't pollute the global namespace. It's designed to coexist with any other JavaScript.

Can I trigger the banner programmatically?

Yes. TinyConsent exposes a JavaScript API for programmatic control: showing preferences, checking consent status, and more.

Is the JavaScript open source?

The core consent logic is proprietary, but we provide documentation for all public APIs and integration methods.
