How to get the size of a filtered (piped) set in angular2

Question

I wrote my own filter pipe as it disappeared in angular2:

import {Pipe, PipeTransform} from \'angular2/core\';

@Pipe({
  name: \'myFilter\'
})
export class          


        

Answer 1

You still must call the filter a second time but you can use it directly like this :

{{ (customerData | myFilter:searchTerm)?.length }}
