React: PropTypes.oneOf([PropTypes.shape(...)])

[brigand]

I have a component that expects one type of object or another. I've tried variations of this:

C.propTypes = {
  foo: PropTypes.oneOf([
    PropTypes.shape({
      x: PropTypes.string
    }).isRequired,

    PropTypes.shape({
      y: PropTypes.string
    })
  ]).isRequired
};

<C foo={{y: 'text'}} />

The warning:

Warning: Failed propType: Invalid prop foo of value [object Object] supplied to C, expected one of [null,null].

Is this a bug, limitation, or am I doing it wrong?

I think you want PropTypes.oneOfType. oneOf is basically an enum.

Oh darn, thanks.

No problem. You're not the first one to do that (and I'm willing to bet you won't be the last :) )

Same here, I was super confused by the error message 👍
