Question

What is React proptype array with shape?

Answer 1

If you want to pass an array of objects to a component with a particular shape then use React.PropTypes.shape() as an argument to React.PropTypes.arrayOf().

ReactComponent.propTypes = {
  arrayWithShape: React.PropTypes.arrayOf(React.PropTypes.shape({
    color: React.PropTypes.string.isRequired,
    fontSize: React.PropTypes.number.isRequired
  })).isRequired
}
