angular - Angular2 Observable error handling in template -

i approach of new angular observables. prevents writing long chain of .done().fail().always(). in jquery. happening under hood in ng2 using | async pipe. how case when there might exceptional case while loading data myobservable. there way how figure out observable failed in template?

// sample.component.ts

class simplecomponent{    myobservable:observable<string>;    constructor(private _someservice:someservice){        myobservable = _someservice.getsomedatabyhttp();    } } 

// simple.component.html

<div>    <div>       {{myobservable | async}}    </div>    <div (anyerrorinobservable)="myobservable"> // kind of construction figure out observable failed load        oops, kind of error appeared while fetching myobservable.    </div> </div> 

i know can done using .catch(). hope there kind of better approach.

thanks advance

there no way handle errors in template. can use operators catch() ensure errors don't reach template.
