Can I convert a boolean or a primitive into an observable?

Question

I have a javascript function which returns an boolean in some cases or an Observable in some other cases. Can I somehow always return an Observable by creating Observable out of a boolean?

Answer 1

You want the rxjs .of() method (https://github.com/Reactive-Extensions/RxJS/blob/master/doc/api/core/operators/of.md) so you can return a observable that emits a boolean

return Observable.of(boolean);
