RxJs - waiting for all Observables to finish
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I've got this piece of code:
myModel.tags
.filter(...)
.map(...)
.forEach(t => context.dispatch(new MyAction(t)))
dispatch returns an Observable.
I'd like to execute other RxJs code only when those Observables are all completed.
Is that possible?

If you want to know when all Observables complete you have to collect all of them into an array and then use ideally forkJoin:
const obs = myModel.tags
.filter(...)
.map(...)
.map(t => context.dispatch(new MyAction(t)))
const done$ = forkJoin(...obs).subscribe(...);
The forkJoin observable creation method will emit just once with the array of all responses and then complete.
