v3.11.9

Patch Changes

• #12110 a3f95c6 Thanks @jerelmiller! - Fix an issue where errors returned from a fetchMore call from a Suspense hook would cause a Suspense boundary to be shown indefinitely.

v3.12.0-alpha.0

Minor Changes

• #12042 1c0ecbf Thanks @jerelmiller! - Introduces data masking into Apollo Client. Data masking allows components to access only the data they asked for through GraphQL fragments. This prevents coupling between components that might otherwise implicitly rely on fields not requested by the component. Data masking also provides the benefit that masked fields only rerender components that ask for the field.

  To enable data masking in Apollo Client, set the dataMasking option to true.

  new ApolloClient({
    dataMasking: true,
    // ... other options
  });

  You can selectively disable data masking using the @unmask directive. Apply this to any named fragment to receive all fields requested by the fragment.

  query {
    user {
      id
      ...UserFields @unmask
    }
  }

  To help with migration, use the @unmask migrate mode which will add warnings when accessing fields that would otherwise be masked.

  query {
    user {
      id
      ...UserFields @unmask(mode: "migrate")
    }
  }

v3.11.8

Patch Changes

• #12054 35cf186 Thanks @phryneas! - Fixed a bug where incorrect object access in some Safari extensions could cause a crash.

v3.11.7

Patch Changes

• #12052 e471cef Thanks @jerelmiller! - Fixes a regression from where passing an invalid identifier to from in useFragment would result in the warning TypeError: Cannot read properties of undefined (reading '__typename').

v3.11.6

Patch Changes

• #12049 9c26892 Thanks @phryneas and @maciesielka! - Fix a bug where useFragment did not re-render as expected

• #12044 04462a2 Thanks @DoctorJohn! - Cache the useSubscription hook's restart function definition between re-renders.

v3.11.5

Patch Changes

• #12027 eb3e21b Thanks @JavaScriptBach! - Type MutationResult.reset as an arrow function

• #12020 82d8cb4 Thanks @jerelmiller! - Better conform to Rules of React by avoiding write of ref in render for useFragment.

v3.11.4

Patch Changes

• #11994 41b17e5 Thanks @jerelmiller! - Update the Modifier function type to allow cache.modify to return deeply partial data.

• #11989 e609156 Thanks @phryneas! - Fix a potential crash when calling clearStore while a query was running.

  Previously, calling client.clearStore() while a query was running had one of these results:

  • useQuery would stay in a loading: true state.
  • useLazyQuery would stay in a loading: true state, but also crash with a "Cannot read property 'data' of undefined" error.

  Now, in both cases, the hook will enter an error state with a networkError, and the promise returned by the useLazyQuery execute function will return a result in an error state.

• #11994 41b17e5 Thanks @jerelmiller! - Prevent accidental distribution on cache.modify field modifiers when a field is a union type array.

v3.11.3

Patch Changes

• #11984 5db1659 Thanks @jerelmiller! - Fix an issue where multiple fetches with results that returned errors would sometimes set the data property with an errorPolicy of none.

• #11974 c95848e Thanks @jerelmiller! - Fix an issue where fetchMore would write its result data to the cache when using it with a no-cache fetch policy.

• #11974 c95848e Thanks @jerelmiller! - Fix an issue where executing fetchMore with a no-cache fetch policy could sometimes result in multiple network requests.

• #11974 c95848e Thanks @jerelmiller! -

  Potentially disruptive change

  When calling fetchMore with a query that has a no-cache fetch policy, fetchMore will now throw if an updateQuery function is not provided. This provides a mechanism to merge the results from the fetchMore call with the query's previous result.

v3.11.2

Patch Changes

• #11980 38c0a2c Thanks @jerelmiller! - Fix missing getServerSnapshot error when using useSubscription on the server.

v3.11.1

Patch Changes

• #11969 061cab6 Thanks @jerelmiller! - Remove check for window.__APOLLO_CLIENT__ when determining whether to connect to Apollo Client Devtools when connectToDevtools or devtools.enabled is not specified. This now simply checks to see if the application is in development mode.

• #11971 ecf77f6 Thanks @jerelmiller! - Prevent the setTimeout for suggesting devtools from running in non-browser environments.
