this.props.children and `react/prop-types` rule

Using this.props.children triggers the rule (“‘children’ is missing in props validation”).

Shouldn’t it be an exception?

All good points. [UPDATED] I think @AsaAyers is onto something, considering the Single Child section in the React doc:

With React.PropTypes.element you can specify that only a single child can be passed to a component as children.

  propTypes: {
    children: React.PropTypes.element.isRequired
  },

In other cases when this.props.children might be used (or not), this below could probably do the trick:

  propTypes: {
    children: React.PropTypes.oneOfType([
      React.PropTypes.arrayOf(React.PropTypes.node),
      React.PropTypes.node
    ])
  },
  getDefaultProps: function() {
    return {
      children: null // or [] I guess
    };
  },

Just to clarify, children should be defined as type node, like this:

propTypes: {
  children: React.PropTypes.node
}
