Angular 7 - virtual scroll combined with async subscription











up vote

I am using async in my Angular 7 project to automatically subscribe my data I want to display. The data is displayed as a table with about 2000 items.



The following code is from my template:



<table class="table table-responsive">
<tr *ngFor="let s of data | async | searchFilter: {keyName: searchText}">
<td>Display some data: {{s.someProperty}}</td>
</tr>
</table>


It is not clear to me how to use this new feature of Angular 7 for only rendering viewable data with still using my pipes async | searchFilter: {keyName: searchText}.



I want to try out this feature because of performance reasons.

  • What have you tried so far? Shouldn't a simple parenthesis wrapper work? (data | async) | searchFilter..?
