Moving Redux state mapper into a component

gistfile1.js

// Trying out a new syntax. It is:
//
//  - not magical except for the DecoratedComponent bit
//  - communicates that it returns props
//  - ...that are computed from Redux data
//  - resembles familiar functions like getInitialProps
//  - nice aesthetically

@connect(data => X.DecoratedComponent.getDataProps(data))
export default class X extends React.Component {

  static getDataProps(data) {
    return {
      propA: data.store.fieldA,
      propB: data.store.fieldB,
    };
  }
}

// instead of

@connect(data => ({
  propA: data.store.fieldA,
  propB: data.store.fieldB,
}))
export default class X extends React.Component {
}
