ConsentBanner

ConsentBanner is a ready-to-use consent banner that appears automatically in opt-in jurisdictions (like GDPR) where explicit consent is required before tracking. In opt-out jurisdictions (like CCPA), the banner won't appear — users get an opt-out mechanism instead. It includes reject, accept, and customize buttons with configurable layout.

Basic Usage

import { ConsentManagerProvider, ConsentBanner } from '@c15t/nextjs';

export function ConsentManager() {
  return (
    <ConsentManagerProvider options={{ mode: 'c15t', backendURL: '/api/c15t' }}>
      <ConsentBanner />
    </ConsentManagerProvider>
  );
}

Customizing Content

Override the default title, description, and button labels:

<ConsentBanner
  title="We value your privacy"
  description="We use cookies to enhance your browsing experience and analyze site traffic."
  acceptButtonText="Accept all"
  rejectButtonText="Reject all"
  customizeButtonText="Manage preferences"
/>;

Button Layout

The layout prop controls button arrangement. Each item is either a button ID or an array of button IDs (which groups them together):

{
  /* Default: reject and accept grouped, customize separate */
}
<ConsentBanner layout={[['reject', 'accept'], 'customize']} />;

{
  /* All buttons in one group */
}
<ConsentBanner layout={[['reject', 'customize', 'accept']]} />;

{
  /* Accept first, then reject and customize grouped */
}
<ConsentBanner layout={['accept', ['reject', 'customize']]} />;

Primary Button

Highlight specific button(s) as the primary action:

{
  /* Single primary */
}
<ConsentBanner primaryButton="accept" />;

{
  /* Multiple primaries */
}
<ConsentBanner primaryButton={['accept', 'customize']} />;

Legal Links

Control which legal links appear in the banner description:

{
  /* Show all configured links (default) */
}
<ConsentBanner legalLinks={undefined} />;

{
  /* Show no links */
}
<ConsentBanner legalLinks={null} />;

{
  /* Show specific links */
}
<ConsentBanner legalLinks={['privacyPolicy', 'cookiePolicy']} />;

Info

Legal link URLs are configured in the ConsentManagerProvider options via the legalLinks prop, not on the banner itself.

Compound Components

Build fully custom banner layouts using sub-components:

<ConsentBanner.Root>
  <ConsentBanner.Overlay />
  <ConsentBanner.Card>
    <ConsentBanner.Header>
      <ConsentBanner.Title />
      <ConsentBanner.Description />
    </ConsentBanner.Header>
    <ConsentBanner.Footer>
      <ConsentBanner.FooterSubGroup>
        <ConsentBanner.RejectButton />
        <ConsentBanner.AcceptButton />
      </ConsentBanner.FooterSubGroup>
      <ConsentBanner.CustomizeButton />
    </ConsentBanner.Footer>
  </ConsentBanner.Card>
</ConsentBanner.Root>;

ConsentBanner.Root — Outermost container, provides theme context
ConsentBanner.Card — Main content card with optional focus trapping
ConsentBanner.Header — Contains title and description
ConsentBanner.Title — Heading, defaults to translation consentBanner.title
ConsentBanner.Description — Description text, supports legalLinks prop
ConsentBanner.Footer — Action buttons container
ConsentBanner.FooterSubGroup — Groups related buttons together
ConsentBanner.RejectButton — Rejects all consent
ConsentBanner.CustomizeButton — Opens the consent dialog
ConsentBanner.AcceptButton — Accepts all consent
ConsentBanner.Overlay — Optional backdrop overlay
