Can I Pass `createAsync()` a Signal?

I'm building an analytics dashboard with the Plausible API.

Their API let's you set the time period for the data you're requesting by appending a period value to your URL string like

&period=6m0

&period=6m0

.

I want to dynamically change this period value when clicking buttons (e.g., "12mo", "month", "7day", etc). So my server function looks like this:

// This is very dumbed down for brevity
export async function getAggregateMetric(range: string) {
  "use server";
  await fetch(`https://plausible.io/api/v1/stats&perdiod=${range}`);
}

// This is very dumbed down for brevity
export async function getAggregateMetric(range: string) {
  "use server";
  await fetch(`https://plausible.io/api/v1/stats&perdiod=${range}`);
}

Here's my question.

I'm using

cache

cache

createAsync()

createAsync()

, and the

load()

load()

function to render the initial data for the page. I'm setting a hard coded value for the first load. But after that I want to let users change the time period by clicking buttons.

I've pasted my design pattern below. Is it a good pattern? I asking because I periodically get a page flicker or refresh when I click the buttons and I can't figure out why.

const getMetrics = cache(
  async (range: string): Promise<AggregateResult | undefined> => {
    "use server";
    return await getAggregateMetrics(range);
  },
  "metrics"
);

// hard coded initial value
export const route = {
  load() {
    void getMetrics("6mo");
  },
};

export default function AddNote() {
  // hard coded initial value
  const [range, setRange] = createSignal("6mo");
  // using a signal here to force createAsync to rerun
  const metrics = createAsync(() => getMetrics(range()));

  function changeMetrics(newRange: string) {
    setRange(newRange);
  };

  return (
    <>
      <h1>Metrics</h1>
      <MetricsBar metrics={metrics}/>
      <button onClick={() => changeMetrics("day")}>Day</button>
      <button onClick={() => changeMetrics("6mo")}>6mo</button>
      <button onClick={() => changeMetrics("12mo")}>12mo</button>
    </>
  );
}

const getMetrics = cache(
  async (range: string): Promise<AggregateResult | undefined> => {
    "use server";
    return await getAggregateMetrics(range);
  },
  "metrics"
);

// hard coded initial value
export const route = {
  load() {
    void getMetrics("6mo");
  },
};

export default function AddNote() {
  // hard coded initial value
  const [range, setRange] = createSignal("6mo");
  // using a signal here to force createAsync to rerun
  const metrics = createAsync(() => getMetrics(range()));

  function changeMetrics(newRange: string) {
    setRange(newRange);
  };

  return (
    <>
      <h1>Metrics</h1>
      <MetricsBar metrics={metrics}/>
      <button onClick={() => changeMetrics("day")}>Day</button>
      <button onClick={() => changeMetrics("6mo")}>6mo</button>
      <button onClick={() => changeMetrics("12mo")}>12mo</button>
    </>
  );
}

Thank you!
