Where is RxJS 6 static merge?

In RxJS 6, how do I import a static merge function for merging a list of Observables?

I want to be able to do:

const merged$ = merge(
obs1$,
obs2$,
obs3$
);


I've tried:

import { merge } from 'rxjs/observable/merge'; and

import { merge } from 'rxjs/observable/merge';

import { merge } from 'rxjs/operators';

import { merge } from 'rxjs/operators';

but neither seems to give me what I want.

Importing has been made easy in RxJS 6:

import {merge} from 'rxjs';


You may want to read the official migration guide.

Another useful resource regarding importing in RxJS 6 is this talk by Ben Lesh who is the RxJS lead.

I believe now when the "creation" classes were removed the recommended way is importing directly from 'rxjs':

'rxjs'

import { merge as mergeStatic } from 'rxjs';


Previous alpha version of RxJS 6 used to have 'rxjs/create' file but this has been removed already: https://github.com/ReactiveX/rxjs/blob/master/CHANGELOG.md#600-alpha3-2018-02-06

'rxjs/create'

However this expects you to use path maps correctly otherwise you'll import a lot of things you don't need. If you don't use path maps or the build process hidden from you you can import directly the correct file:

import { merge as mergeStatic } from 'rxjs/internal/observable/merge';


As of RXJS 6. The merge is in the rxjs/operators

import { map, take, merge, switchMap, filter } from 'rxjs/operators';
