Bypassing the cache

const { loading, error, data } = useQuery(GET_DOGS, {
  fetchPolicy: "no-cache"
});

Persisting the cache

import { AsyncStorage } from 'react-native';
import { InMemoryCache } from '@apollo/client';
import { persistCache } from 'apollo3-cache-persist';

const cache = new InMemoryCache();

persistCache({
  cache,
  storage: AsyncStorage,
}).then(() => {
  // Continue setting up Apollo Client as usual.
})

Resetting the cache

• To reset the cache without refetching active queries, use client.clearStore() instead of client.resetStore().

export default withApollo(graphql(PROFILE_QUERY, {
  props: ({ data: { loading, currentUser }, ownProps: { client }}) => ({
    loading,
    currentUser,
    resetOnLogout: async () => client.resetStore(),
  }),
})(Profile));

Cache redirects

import { ApolloClient, InMemoryCache } from '@apollo/client';

const client = new ApolloClient({
  cache: new InMemoryCache({
    typePolicies: {
      Query: {
        fields: {
          book: {
            read(_, { args, toReference }) {
              return toReference({
                __typename: 'Book',
                id: args.id,
              });
            }
          }
        }
      }
    }
  }
});

Pagination utilities

• Incremental loading: fetchMore
• The @connection directive
