Using RXJS 5.5 pipe function : document.createElement is not a function

[RoyiNamir]

Using "rxjs": "~5.5.2", :

I have pipeable/lettable operators as fields :

hideIndicator = tap(x => this._loadingIndicator.hide());
log = tap(x => ...);
catchError = catchError(error =>....);

Later on I do this :

public post<T>(url: string, params: HttpParams)
        {
            this._loadingIndicator.show();
            return this.http.post<T>(urlJoin(this.actionUrl, url), {params})
                                    .pipe(this.hideIndicator, this.catchError);        //<--- notice pipe  as  operator
        }

This ^ code works fine. But I also have GET/DELETE/PUT commands so I don't want to reapeat :

.pipe(this.hideIndicator, this.catchError);.

So it's possible to declare an aggregte method like :

notice that now pipe should be imported. so let's do it :

And :

But I get an error :

@RoyiNamir it seems that you are hitting this issue where any import from rxjs/Rx will actually import the whole library including the DOM-related stuff.

Remove this line

import { Observable, pipe} from "rxjs/Rx";

and try the following:

import { Observable } from "rxjs/Observable";
import { pipe } from 'rxjs/util/pipe';
