Answer 1

Just for readability created library ngx-if-empty-or-has-items it will check if an object, set, map or array is not empty. Maybe it will help somebody. It has the same functionality as ngIf (then, else and 'as' syntax is supported).

arrayOrObjWithData = ['1'] || {id: 1}


  You will see it


 or 
 // store the result of async pipe in variable
 

  {{obj.id}}


 or

noData = [] || {}

   You will NOT see it
