RxJS: How to Import Just

Question

I would like to use RxJS just.
For this I need Observable.just(null)what is impossible to do with Observable.from().

I'm trying to

import 'rxjs/add/operator/just';

But it is not present where it should be - node_modules/rxjs/add/operatortherefore it will not compile.

How can I add this statement?

Answer 1

It depends on the version of Rx.js:

• 4.0 includes a method .just;
• 5.0 no. Use the method instead .of.

Like this:

Rx.Observable.of(null).forEach(x => console.log(x))
