how to use selectors in redux app with TypeScript?

Question

I try to use selectors from reselect library in my Redux app.

my selectors file looks:

import { createSelector } from 'reselect'

const postsSelectors = state => state.global.posts.allPostse;

export const getPosts = createSelector(
  [ postsSelectors ],
  (posts) => posts
);

and then I try to use in my component, like this:

const mapStateToProps = (state) => ({
  posts: getPosts(state),
});

When I try to compile all of this, I got this error:

I'm guessing that with how I declare types for props, which currently looks like that:

interface Props{
 posts(state: any): any
 loadStories(): void;
};

Help me please resolve this issue. Thanks in advance.

TypeScript is not expecting an array for the first argument. Just pass in your selector functions as arguments to createSelector, as in

export const getPosts = createSelector(
  postsSelectors,
  (posts) => posts
);
