How to make a massive delete in angular 4 with an array of ids

Question

I'm trying to make a massive delete, in order to do that I have an Array<number> of the ids I want to delete. I can't pass this array as a parameter to the method this._httpService.delete(uri,options). The type of _httpService is Http.

So I'm looping the array and inside the loop I'm making single calls, but each call is async and I have certain logic to run when the loop ends.

Actually you can send the id array in the body of a DELETE request, according to this answer, like so:

http.delete('/api/something', new RequestOptions({
    headers: headers,
    body: anyObject    // this would contain your ids
}))

So instead of issuing hundreds of requests, have your app make just one with all ids in the body.
