How to access filtered elements in angular pipe

To access the filtered results of the pipe just define it as a variable via the as keyword

*ngFor="let bookmark of bookmarks | bookmarkFilter: filterText as filteredBookmarks"
Enter fullscreen mode Exit fullscreen mode

In the full example the bookmarkFilter pipe filters the list of bookmarks based on some text search. Further I need to check whether the filtered results contain only one element [showMoreText] = "filteredBookmarks.length === 1 ", to then display the full content of the bookmark:

<div class="mt-3" *ngFor="let bookmark of bookmarks | bookmarkFilter: filterText as filteredBookmarks">
  <app-bookmark-list-element
    [showMoreText] = "filteredBookmarks.length === 1 || bookmarks.length === 1"
    [bookmark]="bookmark"
    [userData$]="userData$"
    [queryText]="queryText"
    [filterText]="filterText"
    [isSearchResultsPage]="isSearchResultsPage"
  >
  </app-bookmark-list-element>
</div>
Enter fullscreen mode Exit fullscreen mode
