effects.ts

import { ThunkAction } from 'redux-thunk';
import { ApplicationState, ApplicationAction } from './types';
import { loadUsersRequest, loadUsersSuccess, loadUsersError } from './actions';
import * as userService from '../services/userService';

type Effect = ThunkAction<any, ApplicationState, any, ApplicationAction>;

export const loadUsers = (): Effect => (dispatch, getState) => {
  dispatch(loadUsersRequest());
  // assume userService.loadUsers returns a Promise<User[]>
  return userService.loadUsers()
    .then(users => dispatch(loadUsersSuccess(users)))
    .catch(() => dispatch(loadUsersError()));
};

what is the type Effect doing here? Why is loadUsers not typed? How does loadUsers infer typing? Not following how this example demonstrates typing an async action creator with Redux.

I've updated the gist to correctly show how loadUsers can infer the type. I accidentally left it out, thanks for pointing it out!
