How to set a team for state in redux?

Question

typescript

const cart = {
  products: (localStorage.getItem("cart") || []),
};

export const CartReduser = (state = cart, action: any) => {}

As a result, the error Object literal's property 'products' implicitly has an 'string | any[]' type.
How to set type for state? More precisely, for products

, localstorage simply returns an array of objects with id and name
