Reusbale fetch api with error handling

fetchAPI.js

export async function fetchData(header, query, url) {
  try {
    const timeout = 8000;
    const controller = new AbortController();
    const id = setTimeout(() => controller.abort(), timeout);
    const response = await fetch(url, {
      method: "POST",
      headers: { ...header },
      body: JSON.stringify(query),
      timeout: timeout,
      signal: controller.signal,
    });
    clearTimeout(id);
    if (!response.ok) {
      const message = `An error has occured: ${response.status}`;
      throw new Error(message);
    }
    const data = await response.json();
    return data;
  } catch (error) {
    return { err: error };
  }
}
