NodeAutoCompleteKit

$nodeAutoComplete = $k->nodeAutoComplete('foo_node')
  ->setTitle($this->t('Foo Node'))
  ->setTargetBundle('foo')
  ->setCondition(
    $q->condition('status')->is()
  )
  ->setCondition(
    $q->condition('field_bar')->isIn(['x', 'y', 'z'])
  );

• The example above relies on the query service provided by query module. You will need to inject the service into your form & set the $q variable accordingly.
• Node filtering is provided by query module's NodeByFieldSelection class.
• If you do not wish to use the query service, you can use NodeAutoCompleteKit::setFilter method instead:

  $nodeAutoComplete = $k->nodeAutoComplete('foo_node')
    ->setTitle($this->t('Foo Node'))
    ->setTargetBundle('foo')
    ->setFilter('status', 1)
