ReactJS propTypes composition

component.jsx

class Component1 extends React.Component {
  static propTypes = {
    some: React.PropTypes.bool,
    prop: React.PropTypes.string,
    types: React.PropTypes.object,
  }
}

class Component2 extends React.Component {
  static propTypes = {
    additional: React.PropTypes.object.isRequired,
    some: React.PropTypes.bool,
    prop: React.PropTypes.string,
    types: React.PropTypes.object,
  }
  
  render() {
    let { additional, ...other } = this.props
    return (
      <Component1 {...other} />
    )
  }
}

@erikras see, I'm still a JS syntax noob! That thing with the ...Component1.propTypes is EXACTLY what I was hoping for! This is perfect, thank you so much!

And I agree that Redux helps with propTypes-hell, just in my special usecase, I'm dealing with props that don't make sense to be stored in a reducer, so that's why I was asking.
