I am going to comment on here, because I think my issue might be related to this.
I am trying to call a function when someone left a session. e.g.
- otSession.current.state.streams.length == 1
- User leaves
- otSession.current.state.streams.length == 0.
However, when I pass the otSession (ref to OTSession) to my component, then in the componentDidUpdate hook I see that prevProps.otSession.current.state.streams.length
will always == this.props,otSession.current.state.streams.length
.
I am assuming the issue might be in the actual library, where streams might be mutated with something like .push() instead of recreated with concat or the spread operator.
EDIT: Solved this need by managing the stream state myself in the component.
componentDidUpdate(prevProps, prevState) {
if (prevProps && prevProps.otSession && prevProps.otSession.current && prevProps.otSession.current.state && prevProps.otSession.current.state.streams) {
let newSubscriberCount = prevProps.otSession.current.state.streams.length;
if (this.state.subscriberCount != newSubscriberCount) {
if (this.state.subscriberCount > newSubscriberCount) {
console.log('person left')
}
this.setState({subscriberCount: newSubscriberCount })
}
}
}
