Proper Way To Get Current State With Immer ?

🙋‍♂ Proper Way To Get Current State

What is the proper way of getting the current state with immer. Do you reassign the output of produce to the state or use something else like "current" which can be imported from the immer package?

Does reassigning not negate the immutability practice of Immer, especially if using Typescript and the state was defined as read-only to enforce immutability. This has not been clear to me from the documentation, hence the question :

import { produce } from "immer";

type AppState = {
    readonly photos: string[];
};

// should state not be read-only and declared with const?
let state: AppState = {
    cards: []
};

// get photos straight from the state at any time. 
// what's the right way??
export const getPhotos = () => state.photos;

export const addPhotos = (...recents: string[]) => {
   // re-assigning state here so we can use its latest update ??
    state = produce(state, (draft) => {
        draft.photos.push(...recents);
    });
    return state.photos;
};

Review the issue's questions about produce, current, reassignment, and readonly TypeScript state. Clarify the recommended way to read the current state and whether reassigning the result of produce preserves Immer's immutability model; done means the documentation explicitly answers these cases.
