I've never used generators before. I was wondering if this is correct:
- i want to fetch all items in an api using do-while and also generators

export async function* fetchAllItems<T>({
  baseUrl = "https://api.example.com/things",
  limit = 250,
}: {
  baseUrl?: string;
  limit?: number;
} = {}): AsyncGenerator<T, void, unknown> {
  let cursor: string | null = null;

  do {
    const url = new URL(baseUrl);
    url.searchParams.set("limit", String(limit));
    if (cursor) url.searchParams.set("cursor", cursor);

    const res = await fetch(url, { headers: { Accept: "application/json" } });
    if (!res.ok) throw new Error(`HTTP ${res.status} fetching ${url}`);
    const json = await res.json();

    const items = (json?.items ?? []) as T[];
    cursor = (json?.nextCursor ?? null) as string | null;

    for (const item of items) yield item;
  } while (cursor);
}
