在处理大型GraphQL响应时,可以采取以下措施来优化Apollo客户端的性能:
const res = await apolloClient.query({
  query: gql`
    query MyQuery($cursor: Int, $limit: Int) {
      items(cursor: $cursor, limit: $limit) {
        id
        name
        # ...
      }
    }
  `,
  variables: {
    cursor: 0,
    limit: 20,
  },
});
query {
  user(id: 123) {
    name
    # ...
    friends @defer {
      name
      # ...
    }
  }
}
import {
  InMemoryCache,
  IntrospectionFragmentMatcher,
} from "apollo-cache-inmemory";
import { CachePersistor } from "apollo-cache-persist";
const cache = new InMemoryCache({
  fragmentMatcher: new IntrospectionFragmentMatcher({
    introspectionQueryResultData: fragmentTypes,
  }),
  cacheRedirects: {
    Query: {
      itemById: (_, args, { getCacheKey }) => getCacheKey({ __typename: "Item", id: args.id }),
    },
  },
});
const persistor = new CachePersistor({
  cache,
  storage: window.localStorage,
});
使用上述解决方法之一可以提高Apollo客户端在处理大型GraphQL响应时的性能。
