Managing Deleted Data in Apollo Client Cache

When building modern web applications with GraphQL, keeping your local client-side cache in sync with your backend database is a common challenge. When a user deletes an item, ensuring it disappears from every view immediately requires a solid understanding of cache management. This text-only course guides you through the foundational concepts of the Apollo Client cache, helping you master eviction techniques so your application user interface always reflects the true state of your data. What you'll learn: - Understand how Apollo Client structures and stores normalized data in its local cache. - Identify when to use cache eviction APIs versus manual cache updates or queries. - Evict deleted items safely using cache.evict and trigger garbage collection with cache.gc. - Update cache fragments and read/write queries to handle deleted relationships. - Practice troubleshooting common cache synchronization issues in real-world scenarios. - Configure modern cache policies to maintain UI responsiveness and consistency. You will start by exploring the fundamentals of normalized caching and cache identity. Then, you will progress through practical text-based walkthroughs and code examples demonstrating how to target, evict, and garbage-collect stale data. This course is designed for frontend developers and software engineers who are familiar with GraphQL basics and want to master Apollo Client cache management. No advanced caching experience is required. Start reading today to build faster, more reliable, and perfectly synchronized user interfaces.
