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:
- Authorizing 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/.
