Creating actions safely with redux typesafety

I've made a mistake several times by forgetting to properly extract the connected action creator from props, as shown below:

import {actionCreator} from 'my-actions';
interface Props {
  actionCreator: typeof (actionCreator);
}

const Foo: React.SFC<Props> = (props) => {
  // Oops, I forgot to access actionCreator from props
  // const { actionCreator } = props; 

  return (<Button 
    onClick={actionCreator} // It would be helpful if this caused a compile error - hint, hint Santa!
  />); 
} 

export const mapDispatch = (dispatch: Dispatch<Action>) => {
  return bindActionCreators({
     actionCreator,
  }, dispatch);
}

export const ConnectedFoo = connect(null, mapDispatch)

The code above will compile without any errors, but unfortunately, it won't trigger any actions in redux.

Answer â„–1

The issue lies in the fact that actionCreator was imported, making it visible throughout the entire module and causing no compile error to occur.

Here are a couple of potential solutions:

1.) Separate the container component and the presentational component into two distinct files: place the import, mapDispatch, and ConnectedFoo in connected_foo.ts, while putting Props and Foo in foo.tsx. This will trigger a compile error.

2.) Rename the property in Foo from actionCreator to something like action or onClick—presentational components should receive actual actions, not action creators.
