How to specify proptypes to allow nullable, required prop value?


How to specify proptypes to allow nullable, required prop value?

I wish this helpful for you I'm not sure if you could get it working in a chainable way (I've thought about it for maybe two minutes), but maybe you could use a custom validator?
code :
function allowNull(wrappedPropTypes) {
  return (props, propName, ...rest) => {
    if (props[propName] === null) return null;
    return wrappedPropTypes(props, propName, ...rest);
  }
}

MyComponent.propTypes = {
  nullOrNumber: allowNull(PropTypes.number.isRequired)
};

hope this fix your issue Ideally if prop('required',true) is working then prop('required',false) should also work. But you can try with removeAttr, hope this helps.
code :
function showBundles(){
        if (document.getElementById("embed").checked){
            $('#div_embed_bundles').show('fast')
            $('#select_embed').prop('required',true);
        }
        else {
            $('#div_embed_bundles').hide('fast')
            $('#select_embed').removeAttr('required');
        }
    }

this will help Change room: React.PropTypes.Object to room: React.PropTypes.object. You've made a typo, object property should start with o in lowercase.

help you fix your problem I have a component that receives a prop for its size. The prop can be either a string or a number ex: "LARGE" or 17.
code :
size: PropTypes.oneOfType([
  PropTypes.string,
  PropTypes.number
]),

I wish this help you , The issue lies in your propTypes definition:
code :
Game.propTypes = {
  game: PropTypes.shape.isRequired,
  actions: PropTypes.shape.isRequired,
};

Hope this helps It's because you are exporting the stateless component directly without any variable holding it meanwhile you are creating propTypes and defaultProps for StyledButton which doesn't exist. Try this.
code :
const StyledButton = props => <button>{props.children}</button>;

StyledButton.propTypes = {
  children: PropTypes.node,
};

StyledButton.defaultProps = {
  children: null,
};

export default StyledButton;
