PDF.js Express Web Viewer contains APIs that allow you to export/import annotations from/to a document. Using those APIs and a server, you can set up realtime collaboration easily. This guide provides a simple example that covers:

  • Authenticating users
  • Exporting/Importing annotation data to/from server
  • Setting the user permissions of each annotation on both server and client side

You can find the full version of the sample in your download package, WebViewer/samples/annotation/realtime-collaboration/.
