用RxJS替代Promise.resolve吗? [英] RxJS alternative to doing a Promise.resolve?

问题描述

RxJS中与Promise.resolve等价的是什么?我知道我可以做Observable.fromPromise(Promise.resolve(someValue));，但是必须有一种更清洁的方法.

What is the equivalent in RxJS to Promise.resolve? I know I can do Observable.fromPromise(Promise.resolve(someValue)); but there has to be a cleaner way.

推荐答案

此小插曲):

Observable.of is what you are looking for (see this plunk):

// You might need to add this import in RxJS versions earlier than 5
import 'rxjs/add/observable/fromArray';

// ... or this line in RxJS 5+
import 'rxjs/add/observable/of';

if (me.groups) {
  return Observable.of(me.groups);
}
