export feature

boot up( application

application register


' component-manager: fundamental', SUPERVISOR , {

 instantiate :  incorrect} );} 
 default { name

: ' register-basic-component-manager',
boot up.
; Following, you can produce a brand-new part course relying on this part supervisor making use of the


 util as complies with: 

// ember-basic-component/app/components/ foo-bar. js  import  EmberObject   from
 ' @ember/ things'
