@apollo/client@4.0.0-rc.1

Major Changes

• #12735 5159880 Thanks @jerelmiller! - Remove deprecated resultCacheMaxSize option from InMemoryCache options.

• #12735 5159880 Thanks @jerelmiller! - Remove deprecated connectToDevtools option from ApolloClientOptions. Use devtools.enabled instead.

Minor Changes

• #12725 89ac725 Thanks @jerelmiller! - Add operationType to operation in ApolloLink. This means that determining whether a query is a specific operation type can now be compared with this property instead of using getMainDefinition.

  - import { getMainDefinition } from "@apollo/client/utilities";
  + import { OperationTypeNode } from "graphql";
  
  ApolloLink.split(
  - ({ query }) => {
  -   const definition = getMainDefinition(query);
  -   return (
  -     definition.kind === 'OperationDefinition' &&
  -     definition.operation === 'subscription'
  -   );
  -   return
  - },
  + ({ operationType }) => {
  +   return operationType === OperationTypeNode.SUBSCRIPTION;
  + },
    conditionTrueLink,
    conditionFalseLink,
  );
  

Patch Changes

• #12728 07a0c8c Thanks @jerelmiller! - Export the IgnoreModifier type from @apollo/client/cache.

• #12735 5159880 Thanks @jerelmiller! - Change the unsafePreviousData argument on UpdateQueryMapFn and SubscribeToMoreQueryFn to a DeepPartial since the result may contain partial data.

• #12734 037979d Thanks @jerelmiller! - Don't warn about a missing resolver if a @client does not have a configured resolver. It is possible the cache contains a read function for the field and the warning added confusion.

  Note that read functions without a defined resolver will receive the existing argument as null instead of undefined even when data hasn't been written to the cache. This is because LocalState sets a default value of null when a resolver is not defined to ensure that the field contains a value in case a read function is not defined rather than omitting the field entirely.

• #12725 89ac725 Thanks @jerelmiller! - Export getMainDefinition from @apollo/client/utilities.

• #12729 699c830 Thanks @jerelmiller! - Ensure useQuery rerenders when notifyOnNetworkStatusChange is false and a refetch that changes variables returns a result deeply equal to previous variables.
