// A button that may exist as a button or a link
// a button only makes sense with an onClick handler
// a link with an href so we base the type of component we return
// based on those props

export const Button: React.StatelessComponent<ButtonInterface> = props => {
  const { onClick, href } = props;
  const Component = onClick ? StyledButton : StyledButton.withComponent('a');

  return <Component {...props}>{ props.children || 'Text' }</Component>;
};


// usage
// <Button href="#">Text</Button> ===> <a href="">Text</a>
// <Button onClick={() => func}>I'm a button</Button> ====> <button></button>




// export const Button: React.StatelessComponent<ButtonInterface> = ({ ...props }) => (
//     <StyledButton {...props}>
//         <Text>{props.text}</Text>
//     </StyledButton>
// );

// also feel like a transparent prop would suffice instead of having a separate button
// so we have the logic with the Link/button--- and props = styling. in this case:
// background-color: ${props => !props.transparent && 'somecolor'}..
export const ButtonTransparent: React.StatelessComponent<ButtonInterface> = ({ ...props }) => (
    <StyledButton transparent={true} {...props}>
        <Text>{props.text}</Text>
    </Button>

Button.defaultProps = {
    transparent: false,
    inline: false,
