Hi, i want to subscribe on invalidate event of the createQuery instance, is there any way I can do this?

Hello @Alexandreee100
You can call .invalidate() and watch for invalidation using returned Promise from this method

const query = createQuery();
query.invalidate().then().catch();    

You can use when() or reaction() from mobx and catch the refetching statement (using query.isRefetching)

const query = createQuery();
query.invalidate();
await when(() => !query.isRefetching && query.isFetched)

You can get access to core tanstack query QueryObserver instance using query.queryObserver and subscribe manually

const query = createQuery();

query.queryObserver.subscribe(query => {
   ...
})
