@cloudpdf/web

Framework-free browser code for CloudPDF's plugins: the one home in the CloudPDF tree for code that touches the DOM, as @embedpdf/web is for EmbedPDF's. The plugins themselves stay DOM-free and take what they need from the host through a port.

The protected display player

browserProtectedPlayer() plays the frames of @cloudpdf/plugin-protected-display: the page as DRM-protected video, in two videos with the keys of one viewing session, through Encrypted Media Extensions and Media Source. FairPlay in Safari, Widevine in Chrome, Edge and Firefox.

import { protectedDisplayPlugin } from '@cloudpdf/plugin-protected-display';

protectedDisplayPlugin({
  // Loaded only for a user who sees the pages as protected video.
  player: () => import('@cloudpdf/web').then((web) => web.browserProtectedPlayer()),
});

The plugin decides which DRM system plays, which frames show and where they sit, and speaks to the server; the player plays what it's given. The CloudPDF viewer (@cloudpdf/viewer) wires this up. Docs: https://www.cloudpdf.com/docs/viewer/features/screenshot-protection
