Code snippets

import PropTypes from 'prop-types';
import React from 'react';
import { StyledButton } from './StyledButton';

const Button = ({
  disabled,
  tag,
  as,
  onClick,
  onMouseOver,
  onMouseOut,
  ...rest
}) => (
  <StyledButton
    as={!as && tag ? tag : as}
    disabled={disabled}
    onClick={onClick}
    onMouseOver={onMouseOver}
    onMouseOut={onMouseOut}
    {...rest}
  />
);

// This is to work around: https://github.com/kadirahq/react-storybook-addon-info/issues/26#issuecomment-229029177
Button.displayName = 'Button';

Button.propTypes = {
  /** The html tag of the button to render with */
  tag: PropTypes.oneOf(['button', 'a']),
  /** The html type of the button, tip: use submit in forms */
  type: PropTypes.oneOf(['button', 'submit']),
  /** The variant colors of the button  */
  variant: PropTypes.oneOf(['primary', 'standard', 'outlined', 'subtle']),
  /** The size of the button  */
  size: PropTypes.oneOf(['small', 'medium', 'large']),
  /** Sets the disabled prop  */
  disabled: PropTypes.bool,
  /** On click callback function  */
  onClick: PropTypes.func,
  /** On Mouse Over callback function  */
  onMouseOver: PropTypes.func,
  /** On Mouse Out callback function  */
  onMouseOut: PropTypes.func,
};

Button.defaultProps = {
  tag: 'button',
  type: 'button',
  variant: 'standard',
  size: 'medium',
  disabled: false,
};

I think there is a point here concerning static build issues. https://github.com/storybooks/storybook/tree/next/addons/info#the-faq

Also, this worked for me to get around the issue as well "storybook:build": "NODE_ENV=development build-storybook -c .storybook -o build"
