I have a pipe which utilizes the httpClient to give a response observable. I have list of request URLs. So, the code looks like this:
let observables = urls.map(url=>myPipe.transform(url));
forkJoin(observables).subscribe(results=>console.log(results));
I want to create a Map/Object which will map the request urls to their respective responses. Like:
{
url1 : response1,
url2 : response2
...
}
I want them to be available at once, so using forkJoin.
CodePudding user response:
I assume your pipe transforms url to http request, so
try this:
let observables = Object.fromEntries(urls.map(url=>[url, myPipe.transform(url)]));
forkJoin(observables).subscribe(results=>console.log(results));
at first we create an object {url: Observable}
, and then with forkJoin
we can do exactly what you asked
