apollo-cache-inmemory

apollo-cache-inmemory is the recommended cache implementation for Apollo Client 2.x, providing a normalized data store without Redux dependency. Version 1.6.6 is the final release; this package is deprecated in favor of @apollo/client which bundles InMemoryCache starting from Apollo Client 3.0. The cache uses a normalized data store with configurable dataIdFromObject, supports readQuery, readFragment, writeQuery, writeFragment for direct cache access, and includes a heuristic fragment matcher with optional introspection support for unions/interfaces. Releases adhere to Apollo Client's schedule (monthly patches, minor releases less frequent). Key differentiator: seamless integration with Apollo Client without external state management.
