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。
