apollographqlDiagnosing Stale or Missing Data in Apollo Client InMemoryCache
When a mutation returns correct data but the UI shows stale or missing values, the cause is usually cache identity or typePolicies. Use this diagnostic guide to isolate the issue before adding refetches.
Apollo Client fetchMore Duplicates or Drops Pages: Diagnosing Cache Merge Failures
A diagnostic guide to Apollo Client pagination failures: why fetchMore duplicates or drops pages, how to inspect the normalized cache, and when to escalate.
Apollo Client InMemoryCache serving stale results under default cache-first policy
Apollo Client's InMemoryCache uses a cache-first fetch policy by default: when a query already has cached results, reads are served from the normalized store without contacting the server. The cache has no built-in time-to-live, so entries persist indefinitely until a mutation writes new data, refetchQueries runs, or entries are evicted. The goal is to keep
graphqlWhat keyFields value does Apollo Client v3 InMemoryCache use for objects without id or _id?
I am configuring Apollo Client v3 InMemoryCache and need to know how cache identity is assigned when a normalized object has neither an id nor an _id field. The documented fallback chain suggests id first, then _id, then storage under the parent path only, but it is unclear whether a custom keyFields policy returning an empty array changes that fallback or p
InMemoryCache typePolicies for Array Merge Strategies
Apollo Client's InMemoryCache utilizes typePolicies to define how incoming data is merged into the normalized store. When dealing with paginated lists or filtered result sets, the default merge behavior may not align with specific UI requirements for data retention or deduplication. The goal is to implement a custom merge function that prevents the overwriti
