I have two subjects: networkStateSubject
and authStateSubject
.
networkStateSubject
emits boolean
value:
true
if network connectivity is enabled,
false
if network connectivity is disabled.
authStateSubject
emits boolean
value:
true
if user logged in,
false
if user logged out.
I need to combine these two subjects, so that whenever both of their values are true
, new value (void
) is emitted from combined observable.
You can use combineLatest
and filter
to check for both values.
const connectedAndAuth$ = combineLatest([networkStateSubject, authStateSubject])
.pipe(
filter(([isConnected, isAuth]) => isConnected && isAuth),
map(_ => 1) //what do you mean emit a void value?
);
