Hi, Max

export function CustomComponentDecorator(_props) {
  _props = Object.assign({}, defaultProps, _props);
  return function (cls) { }
}

Where do we get defaultProps variable from?

Hi, Max
I code with angular13 and I get an error in the compilation phase not runtime check.

Unexpected value ‘AppComponent’ declared by the module ‘AppModule’.
Please add a [@Pipe](http://twitter.com/Pipe)/@Directive/@Component annotation.

What do I need to do?
thanks
