javascript - Apollo 客户端 : Keep/Reset defaults on clearing or resetting store

Question

我使用 apollo-link-state 来本地存储错误，但清除缓存后出现以下错误。

我已在 apollo 客户端配置选项中将 errors 的默认值设置为空数组 []。

但是，在 apolloClient.cache.reset() 或 apolloClient.store.reset() 之后，似乎我丢失了所有默认值，导致此错误:

有什么想法可以解决这个问题吗？

来自docs :

Sometimes you may need to reset the store in your application, for example when a user logs out. If you call client.resetStore anywhere in your application, you will need to write your defaults to the store again. apollo-link-state exposes a writeDefaults function for you. To register your callback to Apollo Client, call client.onResetStore and pass in writeDefaults.

所以你可以这样做:

const cache = new InMemoryCache()
const link = withClientState({ cache, resolvers, defaults })

const client = new ApolloClient({
  cache,
  link,
})

client.onResetStore(stateLink.writeDefaults)
