Raw
angular-cheat-directives-ngclass.md

NgClass

  <div [ngClass]="{bordered: true, 'white-background': false}"></div>
  <div [ngClass]="['class1','class2','class3']"></div>

tip: You can use a classes object in your code and bind it to template

component code

  public classesObj = { /* implement logic that build classes in the object*/ }; // e.g. {bordered: true; strongly: true}

HTML template

  <div [ngClass]="classesObj"></div>
