createReducer allows setting unknown fields to new state

[sregg]

See line 17 nane: action.payload.name, TS is nit complaining about that I typed nane instead of name.

If I add the type manually:

Then I see the error fine.

Is there a way to have the error without the manual type?

Thanks

Here's the code to repro:

import { createAction, createReducer } from 'redux-promise-middleware-actions';

interface IState {
  name: string;
}

const INITIAL_STATE: IState = {
  name: '',
};

const setName = createAction('SET_NAME', (name: string) => ({ name }));

export const NameReducer = createReducer(INITIAL_STATE, handleAction => [
  // intro screen
  handleAction(setName, (state, action) => ({
    ...state,
    nane: action.payload.name,
  })),
]);

Good point, I will try and add this. If you have a solution a PR is of course very welcome :)

Currently it would actually give you a warning if you only set the name property, but because you are spreading the state (...state) it has already set name (to the old value) and will not warn you because you are allowed to extend the object with a new nane prop.
