Created by: dependabot[bot]

Bumps apollo-client from 2.6.8 to 2.6.10.

Changelog

Sourced from apollo-client's changelog.

Apollo Client 3.7.1

Bug fixes

• Fix issue where loading remains true after observer.refetch is called repeatedly with different variables when the same data are returned. @​alessbell in #10143

Apollo Client 3.7.0 (2022-09-30)

New Features

• Implement preview support for the @defer directive. @​alessbell and @​benjamn in #10018

• Implement useFragment_experimental hook, which represents a lightweight live binding into the ApolloCache, and never triggers network requests of its own. @​benjamn in #8782

• Allow registering named fragments with InMemoryCache to support using ...NamedFragment in queries without redeclaring NamedFragment repeatedly in every query that uses it. @​benjamn in #9764

• Support onError callback for useSubscription hook. @​jeroenvisser101 in #9495

Improvements

• Delay calling onCompleted and onError callbacks passed to useQuery using Promise.resolve().then(() => ...) to fix issue #9794. @​dylanwulf in #9823

• Replace concast.cleanup method with simpler concast.beforeNext API, which promises to call the given callback function just before the next result/error is delivered. In addition, concast.removeObserver no longer takes a quietly?: boolean parameter, since that parameter was partly responsible for cleanup callbacks sometimes not getting called. @​benjamn in #9718

• Allow preserving header name capitalization when creating an HttpLink with createHttpLink({ uri, preserveHeaderCase: true }). Otherwise, header names are converted to lowercase to prevent case-sensitivity bugs. @​MrDoomBringer in #9891

• Make queries with a pollInterval respect the no-cache fetch policy, instead of writing polled results into the cache. @​MrDoomBringer in #10020

• Deprecate the onSubscriptionData callback in favor of a new onData callback for the useSubscription hook. Deprecate the onSubscriptionComplete callback in favor of a new onComplete callback for the useSubscription hook. @​jerelmiller in #10134

Potentially disruptive

• The optional subscribeAndCount testing utility exported from @apollo/client/testing/core now takes a single generic TResult type parameter, instead of TData. This type will typically be inferred from the observable argument type, but if you have any explicit calls to subscribeAndCount<TData>(...) in your own codebase, you may need to adjust those calls accordingly. @​benjamn in #9718

Apollo Client 3.6.10 (2022-09-29)

Improvements

• The client options (variables, context, etc.) used for mutation calls are now available as the second argument to the onCompleted and onError callback functions.
