Mutate cache data

[bartoszkrawczyk2]

Hi!

Is there a pattern to optimistic mutate data loaded with cache and createAsync ? Similar to mutate in createResource.

Would be great to be able to preload data on the server with use server in cache, but be able to update it on client side while calling revalidate to show optimistic state.

Thanks!

There is a cache.set method. We need to document it though. It takes a key, value.

Hi!

Does this update the value of the data from the createAsync?

For example:

const loadAboutData = cache(async () => {
  return new Promise((resolve) =>
    setTimeout(resolve, 500, "Solid")
  ) as Promise<string>;
}, "about");


export default function About() {
  const name = createAsync(() => loadAboutData());
  return (
    <section class="p-8">
      <Suspense fallback={<p>...</p>}>
        <p>{name()}</p>
      </Suspense>
      <button
        onClick={() => {
          // optimistically update the data

cache.set(loadAboutData.key, "TEST");
// mutation
        }}>
        Test
      </button>
    </section>
  );
}

Would this be able to change name() from "Solid" to "TEST" or is there another way to do this?

Thanks!
