How to use SSR with Stores on SvelteKit

I am new to sveltekit and svelte in general, and I am trying to load data from an API to the stores, here is how I am doing it

    export const load = async ({ fetch }) => {
        const data = get(dataStore);

        if (browser && data) {
            return { status: 200 };
        }

        const res = await fetch('/data.json', { credentials: 'include', mode: 'cors' });
        const data = await res.json();

        if (browser) {
            dataStore.set(data);
        }

        return { status: res.status };
    };

my question is what is best approach to load data on SSR to the FE stores ?
