Bits of .NET

Network flickers happen. If a request fails, don’t just show an error; try again—but wait longer each time to avoid overloading the server.

async function fetchWithRetry(url, retries = 3, delay = 1000) {
  try {
    return await fetch(url);
  } catch (err) {
    if (retries === 0) throw err;
    await new Promise(r => setTimeout(r, delay));
    return fetchWithRetry(url, retries - 1, delay * 2);
  }
}
