ReactJs: What should the PropTypes be for this.props.children?

Question

Given a simple component that renders its children:

class ContainerComponent extends Component {
  static propTypes = {
    children: PropTypes.object.isRequ         


        

Answer 1

If you want to match exactly a component type, check this

MenuPrimary.propTypes = {
  children: PropTypes.oneOfType([
    PropTypes.arrayOf(MenuPrimaryItem),
    PropTypes.objectOf(MenuPrimaryItem)
  ])
}

If you want to match exactly some component types, check this

const HeaderTypes = [
  PropTypes.objectOf(MenuPrimary),
  PropTypes.objectOf(UserInfo)
]

Header.propTypes = {
  children: PropTypes.oneOfType([
    PropTypes.arrayOf(PropTypes.oneOfType([...HeaderTypes])),
    ...HeaderTypes
  ])
}
