Local resolvers are still available in Apollo Client 3, but they are deprecated. We recommend using field policies instead, as described in [Local-only fields](./managing-state-with-field-policies/). Local resolver support will be removed from the core of Apollo Client in a Major release and in a future major release it will be possible to achieve the functionality of local resolvers using an `ApolloLink`, as described in [this issue](https://github.com/apollographql/apollo-client/issues/10060). ### References - https://www.apollographql.com/docs/react/local-state/local-resolvers/ - https://github.com/apollographql/apollo-client/issues/10060 - https://github.com/apollographql/apollo-client/issues/7072 - https://github.com/apollographql/apollo-client/issues/8189
