Request for New Feature: Enhancing Decorator Functionality with Queuing Mechanism

[xziy]

---

Feature Request:

Overview:

The current decorator function, queued(), aims to provide a queuing mechanism for asynchronous operations. However, it could be improved to offer enhanced functionality and broader applicability.

Code Sample:

interface QueueItem {
  queue: Promise<void>;
}

function queued() {
  return function (_target: any, _key: string, descriptor: TypedPropertyDescriptor<(...args: any[]) => Promise<any>>) {
    const operationQueue: QueueItem = { queue: Promise.resolve() };

    const method = descriptor.value!;
    descriptor.value = async function (...args: any[]) {
      const operation = operationQueue.queue.then(async () => {
        return await method.apply(this, args);
      });
      operationQueue.queue = operation.catch(() => {});
      return operation;
    };
    return descriptor;
  };
}

Additional Information:

• Use Case: The feature would benefit applications handling numerous asynchronous tasks, such as server-side processing or background jobs.
• Compatibility: Ensuring backward compatibility with existing code utilizing the queued() decorator will be crucial for seamless adoption.

Possible Implementation:

• Throttling: Implement a throttling mechanism within the queue to manage the rate of execution.
• Configuration Options: Introduce parameters or options within the decorator to customize queuing behavior.

Your contributions and insights to enhance this decorator are highly appreciated. Thank you for considering this request.

Hi, can't you achive the same withthe ThrottleAsync decorator: https://vlio20.github.io/utils-decorators/#throttleAsync
