react-results-proptypes v0.5.1

Results PropTypes for React

$ npm install react-results-proptypes

import { unionOf, maybeOf } from 'react-results-proptypes';

// this would be declared somewhere else in the app and imported
const MyUnion = Union({ A: null, B: null, C: null });

const MyComponent = React.createClass({
  propTypes: {
    maybeAString: maybeOf(React.PropTypes.string),
    thingFromMyUnion: unionOf(MyUnion, {
      A: React.PropTypes.string,
      B: React.PropTypes.number,
      C: null,
    }),
  },
  ...
});

The component above would pass checks if:

• maybeAString were Maybe.None() or Maybe.Some('string')
• thingFromMyUnion were any of
  • MyUnion.A('blah'),
  • MyUnion.B(42),
  • MyUnion.C()
