Subscribe is deprecated: Use an observer instead of an error callback

RxJS deprecated some signatures of the subscribe method, which might have caused some confusion. The subscribe method itself isn\’t deprecated, only the variant we\’re using is deprecated. So here it looks like

.subscribe({ 
 next: (response) => { console.log(response); },
 error: (e) => { console.log(e); } 
 });
 
 
 or 
 
 
 .subscribe({
 next(response) { console.log(response) },
 error(e) { console.log(e); }
 });

import { of } from \'rxjs\';
 
 // deprecated
 of([1,2,3]).subscribe(null, null, console.info); // difficult to read
 // suggested change
 of([1,2,3]).subscribe({complete: console.info});

import { throwError } from \'rxjs\';
 
 // deprecated 
 throwError(\'I am an error\').subscribe(null, console.error);
 // suggested change
 throwError(\'I am an error\').subscribe({error: console.error});

import { of } from \'rxjs\';
 
 // recommended 
 of([1,2,3]).subscribe((v) => console.info(v));
 // also recommended
 of([1,2,3]).subscribe({
     next: (v) => console.log(v),
     error: (e) => console.error(e),
     complete: () => console.info(\'complete\') 
 })
