apollo-caching-strategies

Master Apollo caching for efficient data management and performance.

• Use cache policies to control data fetching behavior.
• Implement normalization to avoid duplicate data in cache.
• Manage cache reads/writes for dynamic data updates.
• Apply optimistic UI to show updates before network response.

• Cache policies control data retrieval order (cache-first, network-only, etc.).
• Normalize data to prevent duplication in memory.
• Merge functions update cache during data updates.
• Optimistic updates show changes before network response.
• Read/write operations allow direct cache access and modification.
• Cache reads avoid unnecessary network calls.
• Cache writes update data without re-fetching.
• Cache policies impact performance and user experience.

1. 1.Configure InMemoryCache with type policies and key fields.
2. 2.Set fetchPolicy (e.g., cache-first, network-only) based on use case.
3. 3.Use readQuery/readFragment to access cached data directly.
4. 4.Use writeQuery/writeFragment to update cache data.
5. 5.Apply cache.modify for field-level updates.
6. 6.Use optimisticResponse and update functions for real-time UI updates.
