This structure contains almost exclusively references to DOM elements (and a couple of simple strings), rather than complete classes/functions. Hence the
eventBus
-option sticks out a fair bit, and I'd guess that it's mostly unused in e.g. third-party implementations.Given that we, in multiple places, mention that the default viewer shouldn't be used as-is I really don't think that we need to keep this special
eventBus
-option around. Furthermore, nowadays it's also a lot easier to (safely) access the existingEventBus
-instance in the viewer; see https://github.com/mozilla/pdf.js/wiki/Third-party-viewer-usage#initialization-promise which shows how to listen for the default viewer being initialized (and itseventBus
thus being available).
