Q: add a property

[basz]

Hi,

I'm trying to add an option to some Errors but looking at your code the options are not stored inside the instance.

Also, the 'ember way' of using reopen does not work as these errors are not an ember object.

MaintenanceError.reopen({
  useRouter: true, /* would navigate away from the UI where the issue happened */
  useNotification: true, /* use a notification service */
});

So my question is a JS one. How would I add a property to an error definition?

To answer my own question, something this seems to work

const MaintenanceError = defineError({
  name: 'MaintenanceError',
  message: 'Down for maintenance.'
});

MaintenanceError.prototype.useRouter = true;
MaintenanceError.prototype.useNotification = false;

MaintenanceError.prototype.withNotification = function() {
  this.useRouter = false;
  this.useNotification = true;

  return this;
};

MaintenanceError.prototype.withRouter = function() {
  this.useRouter = true;
  this.useNotification = false;

  return this;
};

export default MaintenanceError;
