Using ngclass in Stencil.js

Question

The below is the code in Angular 2. Could someone explain how to use ngclass in Stencil.js.

I have created the component is Angular2. Now trying to recreate the same in Stenciljs:

<div class="inner_holder" [ngClass]="isSelected(day)">
  <div class="col day">{{day.month}}</div>
     <div class="col date">
       <span>{{day.date}}</span>
     </div>
</div>    

TypeScript Code:

isSelected(day) {
  return (day.fullDay === this.selectedDay) ? "active" : "";
 }

You can also use following syntax:

<div 
  class={{
    'error': this.hasError,
    'hidden': !this.isOpen
  }}
