Answer 1

you could use a pipe to filter those projects based on your condition (that passes only for those 'unique ids') and apply them on your *ngFor in the template like this,

Define the pipe like this,

@Pipe({
  name: 'uniqueOnes'
})
export class UniqueOnesPipe implements PipeTransform {
  uniqueIds = [ 'id1', 'id2', 'id5'];

  transform(value: any): any {
    return value
            ? value.filter(project => { return   })
            : value;
  }

}
