How to detect the first attendee join the meeting.

What happened and what did you expect to happen?

Hi,

I want to set a host person who join the meeting first, but I'm not sure how to determine who is the first attendee join the meeting.

Hope you can help.

Thanks,

Reproduction steps

we have the hook useRoster() to return all attendees in the meeting session but it's not enough information to detect which is the first one join the meeting.

From JS SDK side, there is no standard way of knowing who joined first. You can use the realtimeSubscribeToAttendeeIdPresence and check the order of the attendees.

From my testing the realtimeSubscribeToAttendeeIdPresence update for an attendee comes like this: Scenario

• Attendee venky1 joins a meeting (Meeting A) as first attendee.
• Attendee venky2 joins the same meeting as second attendee.
• Then later venky3 joins as third attendee.

The Attendee venky3 receives three updates like below:

[DEMO] <venky3 AttendeeId> present = true (19dcc9cc#venky3) <-- Self, but third attendee
(index):2 [DEMO] <venky1 AttendeeId> = true (b03536dc#venky1) <-- First attendee
(index):2 [DEMO] <venky2 AttendeeId> present = true (dfa815ea#venky2) <-- Second attendee

You can use the pattern and see whether this satisfies your use case.

A better way is to use server side meeting event notifications:
