Batching, queuing, and debouncing at once

[WillisShek]

I would like to create a batcher that

1. only execute 1s after the last item is added (similar to debouncing)
2. wait for the pending call to complete before firing the next one (similar to queuing with maxSize: 1)

May I ask is it possible? It is fine that if point 1 is not achievable but point 2 is a must in my use case.

From what I understand, point 2 can be done with the following.

const batcher = new AsyncBatcher<string>(
  async (items) => {
    const results = await processBatch(items);
    return results;
  },
  {
    wait: 1000,
    onExecute: (batch, batcher) => {
      batcher.stop();
    }
    onSettled: (batch, batcher) => {
      batch.start();
    }
  }
)

Is there any other way that can achieve it?

Thank you.

Update: I found that point 1 is solved naturally with wait: 1000.
