Better way of reusing event listeners for hooks

import { Accessor, onCleanup, onMount } from 'solid-js';
import { createSignal } from 'solid-js';

export const useWindowSize = (): {
    width: Accessor<number>;
    height: Accessor<number>;
} => {
    const [width, setWidth] = createSignal(0);
    const [height, setHeight] = createSignal(0);

    const handle = () => {
        setWidth(window.innerWidth);
        setHeight(window.innerHeight);
    };

    onMount(() => {
        window.addEventListener('resize', handle);
        handle();
    });

    onCleanup(() => window.removeEventListener('resize', handle))

    return { width, height };
}

import { Accessor, onCleanup, onMount } from 'solid-js';
import { createSignal } from 'solid-js';

type Callback = (width: number, height: number) => void;

const cbMap: {[key: string]: Callback} = {};

const unsub = (uuid: string) => {
