Fulfill with Time Limit

export async function fulfillWithTimeLimit(
  timeLimit: number,
  promise: Promise<unknown>,
): Promise<unknown> {
  let timeoutPid: NodeJS.Timeout;

  const timeout = new Promise<unknown>(
    (resolve, reject) =>
      (timeoutPid = setTimeout(
        () => reject(new Error(`Timed out after ${timeLimit} ms.`)),
        timeLimit,
      )),
  );

  return Promise.race([promise, timeout]).finally(() => {
    if (timeoutPid) {
      clearTimeout(timeoutPid);
    }
  });

Example

  async function fetchData(): Promise<string> {
    // Simulate an API call that takes some time
    return new Promise((resolve) => {
      setTimeout(() => {
        resolve('Data fetched successfully');
      }, 2000); // This promise resolves after 2 seconds
    });
  }

  try {
    const result = await fulfillWithTimeLimit(1000, fetchData());
    console.log(result);
  } catch (error) {
    console.error(error.message); // Expected to log: "Timed out after 1000 ms."
  }

  try {
    const result = await fulfillWithTimeLimit(3000, fetchData());
    console.log(result); // Expected to log: "Data fetched successfully"
  } catch (error) {
    console.error(error.message);
  }
