SelectorsFromSlices type​

Extracts the bound selectors type from an array of slices.

Signature:

export type SelectorsFromSlices<S extends SliceArray> = {
    [K in S[number]['name']]: {
        [SelectorKey in keyof Extract<S[number], {
            name: K;
        }>['selectors']]: (...payload: RemoveFirstParameter<Extract<S[number], {
            name: K;
        }>['selectors'][SelectorKey]>) => ReturnType<Extract<S[number], {
            name: K;
        }>['selectors'][SelectorKey]> extends void ? any : ReturnType<Extract<S[number], {
            name: K;
        }>['selectors'][SelectorKey]>;
    };
};

Remarks​

This utility type creates a nested object structure where each slice name maps to its selectors. Selectors are bound to the store and can access the current state.

Example​

const { selectors } = createStore([userSlice, cartSlice], initialState);
// const userName = selectors.user.getUserName()
// const cartTotal = selectors.cart.getTotal()
