Purging InMemoryCache when switching stories

[toyflish]

I have apolloclient for storybook configured with InMemoryCache to have the same behavior in storybook as in my app.
Switching component stories keeps the old state of the cache alive, so I have to refresh the browser to purge it.
If I call client.clearStore() inside my stories, I can purge the cache.
I tried to create a decorator that does a client.clearStore() on ApolloClient. But I can not get it chained to be inside the ApolloProvider. Seems like the Apollo context gets added inside the decorators. So I ended up adding the decorator as a wrapper inside every ComponentStory.

How could I achieve some global way to purge the cache when switching to another story?

my cache purging component:

export default function ApolloCacheClearDecorator({children}: {children: JSX.Element}) {
  const [cleared, setCleared] = useState(false);

  const client = useApolloClient();

  useEffect(() => {
    if (cleared) return;
    client.clearStore();
    setCleared(true);
  }, [cleared, client]);

  if (!cleared) return <div>Clearing Apollo cache...</div>;

  return children;
}

my apollo config in .storybook/preview.js

import {MockedProvider} from '@apollo/client/testing';
import {PageDecorator} from '../src/storybook/PageDecorator';
import {withRouter} from 'storybook-addon-react-router-v6';

export const apolloCacheConfig = new InMemoryCache({
  typePolicies: {
    Google: {
      merge: true,
    },
  },
});


export const parameters = {
  apolloClient: {
    MockedProvider,
    cache: apolloCacheConfig,
  },
};
export const decorators = [PageDecorator, withRouter];

@toyflish great question, it's still an unknown, but I've asked in the discord here: https://discord.com/channels/486522875931656193/1089766870036525116/1089766870036525116 once I get a response, I'll see if I can put together a solution for you.

@toyflish is this still an issue for you? If so can you outline some expectations you'd have for the addon to do that it currently doesn't?
