Patch Changes

• #13229 9a7f65a Thanks @jerelmiller! - Fix refetchOn merging when defaultOptions.watchQuery.refetchOn is set to a non-object value (false, true, or a function) and the per-query refetchOn is an object. Previously the per-query object completely replaced the default so unspecified events fell back to "enabled" regardless of the default.

  The defaultOptions value now applies to any event the per-query object does not explicitly configure:

  • false - unspecified events stay disabled
  • true - unspecified events refetch
  • Callback function - the function is called for unspecified events to determine whether to refetch

  const client = new ApolloClient({
    // ...
    defaultOptions: {
      watchQuery: {
        refetchOn: false,
      },
    },
  });
  
  // Only `windowFocus` refetches. Other events stay disabled per the default.
  useQuery(QUERY, { refetchOn: { windowFocus: true } });

• #13230 b25b659 Thanks @jerelmiller! - Add the ability to override the default event handler on RefetchEventManager. The default handler runs when no per-source handler is configured for an event. Provide a custom handler via the defaultHandler constructor option or the setDefaultEventHandler instance method.

  new RefetchEventManager({
    defaultHandler: ({ client, matchesRefetchOn }) => {
      return client.refetchQueries({
        include: "all",
        onQueryUpdated: matchesRefetchOn,
      });
    },
  });
