Patch Changes

• #​12285 cdc55ff Thanks @​phryneas! - keep ObservableQuery created by useQuery non-active before it is first subscribed

v3.13.5

Patch Changes

• #​12461 12c8d06 Thanks @​jerelmiller! - Fix an issue where a cache-first query would return the result for previous variables when a cache update is issued after simultaneously changing variables and skipping the query.

v3.13.4

Patch Changes

• #​12420 fee9368 Thanks @​jorenbroekema! - Use import star from rehackt to prevent issues with importing named exports from external CJS modules.

v3.13.3

Compare Source

Patch Changes

• #​12362 f6d387c Thanks @​jerelmiller! - Fixes an issue where calling observableQuery.getCurrentResult() when the errorPolicy was set to all would return the networkStatus as NetworkStatus.ready when there were errors returned in the result. This has been corrected to report NetworkStatus.error.

  This bug also affected the useQuery and useLazyQuery hooks and may affect you if you check for networkStatus in your component.

v3.13.2

Compare Source

Patch Changes

• #​12409 6aa2f3e Thanks @​phryneas! - To mitigate problems when Apollo Client ends up more than once in the bundle, some unique symbols were converted into Symbol.for calls.

• #​12392 644bb26 Thanks @​Joja81! - Fixes an issue where the DeepOmit type would turn optional properties into required properties. This should only affect you if you were using the omitDeep or stripTypename utilities exported by Apollo Client.

• #​12404 4332b88 Thanks @​jerelmiller! - Show NaN rather than converting to null in debug messages from MockLink for unmatched variables values.

v3.13.1

Patch Changes

• #​12369 bdfc5b2 Thanks @​phryneas! - ObervableQuery.refetch: don't refetch with cache-and-network, swich to network-only instead

• #​12375 d3f8f13 Thanks @​jerelmiller! - Export the UseSuspenseFragmentOptions type.

v3.13.0

Compare Source

Minor Changes

• #​12066 c01da5d Thanks @​jerelmiller! - Adds a new useSuspenseFragment hook.

  useSuspenseFragment suspends until data is complete. It is a drop-in replacement for useFragment when you prefer to use Suspense to control the loading state of a fragment. See the documentation for more details.

• #​12174 ba5cc33 Thanks @​jerelmiller! - Ensure errors thrown in the onCompleted callback from useMutation don't call onError.

• #​12340 716d02e Thanks @​phryneas! - Deprecate the onCompleted and onError callbacks of useQuery and useLazyQuery.
  For more context, please see the related issue on GitHub.

• #​12276 670f112 Thanks @​Cellule! - Provide a more type-safe option for the previous data value passed to observableQuery.updateQuery. Using it could result in crashes at runtime as this callback could be called with partial data even though its type reported the value as a complete result.

  The updateQuery callback function is now called with a new type-safe previousData property and a new complete property in the 2nd argument that determines whether previousData is a complete or partial result.

  As a result of this change, it is recommended to use the previousData property passed to the 2nd argument of the callback rather than using the previous data value from the first argument since that value is not type-safe. The first argument is now deprecated and will be removed in a future version of Apollo Client.

  observableQuery.updateQuery(
    (unsafePreviousData, { previousData, complete }) => {
      previousData;
      // ^? TData | DeepPartial<TData> | undefined
  
      if (complete) {
        previousData;
        // ^? TData
      } else {
        previousData;
        // ^? DeepPartial<TData> | undefined
      }
    }
  );

• #​12174 ba5cc33 Thanks @​jerelmiller! - Reject the mutation promise if errors are thrown in the onCompleted callback of useMutation.

Patch Changes

• #​12276 670f112 Thanks @​Cellule! - Fix the return type of the updateQuery function to allow for undefined. updateQuery had the ability to bail out of the update by returning a falsey value, but the return type enforced a query value.

  observableQuery.updateQuery(
    (unsafePreviousData, { previousData, complete }) => {
      if (!complete) {
        // Bail out of the update by returning early
        return;
      }
  
      // ...
    }
  );

• #​12296 2422df2 Thanks @​Cellule! - Deprecate option ignoreResults in useMutation.
  Once this option is removed, existing code still using it might see increase in re-renders.
  If you don't want to synchronize your component state with the mutation, please use useApolloClient to get your ApolloClient instance and call client.mutate directly.

• #​12338 67c16c9 Thanks @​phryneas! - In case of a multipart response (e.g. with @defer), query deduplication will
  now keep going until the final chunk has been received.

• #​12276 670f112 Thanks @​Cellule! - Fix the type of the variables property passed as the 2nd argument to the subscribeToMore callback. This was previously reported as the variables type for the subscription itself, but is now properly typed as the query variables.

v3.12.11

Compare Source

Patch Changes

• #​12351 3da908b Thanks @​jerelmiller! - Fixes an issue where the wrong networkStatus and loading value was emitted from observableQuery when calling fetchMore with a no-cache fetch policy. The networkStatus now properly reports as ready and loading as false after the result is returned.

• #​12354 a24ef94 Thanks @​phryneas! - Fix missing main.d.cts file

Patch Changes

• #​12341 f2bb0b9 Thanks @​phryneas! - useReadQuery/useQueryRefHandlers: Fix a "hook order" warning that might be emitted in React 19 dev mode.

• #​12342 219b26b Thanks @​phryneas! - Add graphql-ws ^6.0.3 as a valid peerDependency

v3.12.9

Compare Source

Patch Changes

• #​12321 daa4f33 Thanks @​jerelmiller! - Fix type of extensions in protocolErrors for ApolloError and the onError link. According to the multipart HTTP subscription protocol, fatal tranport errors follow the GraphQL error format which require extensions to be a map as its value instead of an array.

• #​12318 b17968b Thanks @​jerelmiller! - Allow RetryLink to retry an operation when fatal transport-level errors are emitted from multipart subscriptions.

  const retryLink = new RetryLink({
    attempts: (count, operation, error) => {
      if (error instanceof ApolloError) {
        // errors available on the `protocolErrors` field in `ApolloError`
        console.log(error.protocolErrors);
      }
  
      return true;
    },
  });

v3.12.8

Patch Changes

• #​12292 3abd944 Thanks @​phryneas! - Remove unused dependency response-iterator

• #​12287 bf313a3 Thanks @​phryneas! - Fixes an issue where client.watchFragment/useFragment with @includes crashes when a separate cache update writes to the conditionally included fields.

v3.12.7

Compare Source

Patch Changes

• #​12281 d638ec3 Thanks @​jerelmiller! - Make fatal tranport-level errors from multipart subscriptions available to the error link with the protocolErrors property.

  const errorLink = onError(({ protocolErrors }) => {
    if (protocolErrors) {
      console.log(protocolErrors);
    }
  });

• #​12281 d638ec3 Thanks @​jerelmiller! - Fix the array type for the errors field on the ApolloPayloadResult type. This type was always in the shape of the GraphQL error format, per the multipart subscriptions protocol and never a plain string or a JavaScript error object.

v3.12.6

Compare Source

Patch Changes

• #​12267 d57429d Thanks @​jerelmiller! - Maintain the TData type when used with Unmasked when TData is not a masked type generated from GraphQL Codegen.

• #​12270 3601246 Thanks @​jerelmiller! - Fix handling of tagged/branded primitive types when used as scalar values with Unmasked.

v3.12.5

Compare Source

Patch Changes

• #​12252 cb9cd4e Thanks @​jerelmiller! - Changes the default behavior of the MaybeMasked type to preserve types unless otherwise specified. This change makes it easier to upgrade from older versions of the client where types could have unexpectedly changed in the application due to the default of trying to unwrap types into unmasked types. This change also fixes the compilation performance regression experienced when simply upgrading the client since types are now preserved by default.

  A new mode option has now been introduced to allow for the old behavior. See the next section on migrating if you wish to maintain the old default behavior after upgrading to this version.

Migrating from <= v3.12.4

If you've adopted data masking and have opted in to using masked types by setting the enabled property to true, you can remove this configuration entirely:

-declare module "@​apollo/client" {
-  interface DataMasking {
-    mode: "unmask"
-  }
-}

If you prefer to specify the behavior explicitly, change the property from enabled: true, to mode: "preserveTypes":

declare module "@​apollo/client" {
  interface DataMasking {
-    enabled: true
+    mode: "preserveTypes"
  }
}

If you rely on the default behavior in 3.12.4 or below and would like to continue to use unmasked types by default, set the mode to unmask:

declare module "@​apollo/client" {
  interface DataMasking {
    mode: "unmask";
  }
}
