Typescript
This is a typescript definition that was quickly developed. It probably has room for improvement.
declare module 'reduction-sauce' {
import {MapStateToProps, MapDispatchToPropsFunction, MapDispatchToPropsObject, MergeProps, Options, ClassDecorator} from 'react-redux'
export function reductionReducer(): any;
export function reductionSauce(
reductionOptions: {key: string},
mapStateToProps?: MapStateToProps,
mapDispatchToProps?: MapDispatchToPropsFunction|MapDispatchToPropsObject|Object,
mergeProps?: MergeProps,
options?: Options): ClassDecorator
}
