how to return an empty observable

Question

according to this answer How to return an empty observable in rxjs i have tried all of it but it did not work for me

here is my code

post(url):Observalbe<any>{
   if(this.holder.nullConnection()){ //checking internet connection
      //return empty observalbe
      return Observable.empty() ;
    }else{
      return this.http.post(this.configurator.restServerBaseUrl+url,data)
      .map((result:Response)=> {
        return result.json()
      })
    }
}

i have tried almost all the answers as per the stack question you can see above any help to return an empty obserable.

Solution

Observable.of() should work for your case:

import {Observable} from 'rxjs/Observable';
import 'rxjs/add/observable/of';
// or import {Observable} from 'rxjs/Rx';

return Observable.of();

or

import {EmptyObservable} from 'rxjs/EmptyObservable';

return new EmptyObservable();

@GünterZöchbauer [ts] Property 'of' does not exist on type 'typeof Observable'. this is the error
