@espuni/browser

Browser SDK for the espuni Age Verification flow. Encapsulates the DC API → OID4VP/QR fallback so relying parties don't reimplement it, built over the shared @espuni/core logic.

• Prefers the Digital Credentials API (ISO 18013-7) when the browser supports it and the session carries orgIsoMdoc; otherwise falls back to the OID4VP QR/deeplink flow (av:// rewrite via core, configurable).
• Resolves the result via your backend's poll and/or SSE endpoint (poll is fetched with cache: 'no-store').
• Render-agnostic QR: pass a container (+ optional renderQr, defaults to window.QRCode/qrcodejs) or take the derived links from onLinks and render them yourself.

Decoupled from any specific backend: your server creates the session with the espuni API (or @espuni/node) and hands the browser the session plus the URLs on your backend for DC API submission and result polling.

<script src="https://unpkg.com/@espuni/browser"></script>
<script>
  espuni.verify({
    session,                              // from your server (createSession)
    dcApiSubmitUrl: '/av/dc-response/' + session.sessionId,
    pollUrl: '/av/session/' + session.sessionId,
    container: document.getElementById('qr'),
    onSuccess: (r) => console.log('verified', r.ageOver18),
    onFailure: (e) => console.warn(e.error),
  });
</script>

Or via npm: import { verify, hasDcApi } from '@espuni/browser'.

Ships ESM/CJS (import) and an IIFE global (window.espuni, for <script>/CDN). @espuni/core is bundled in — no runtime dependency.
