Apollo Client: Managing Cache and Automatic Mutation Updates

Keeping your local application state in sync with your database can be challenging. Apollo Client solves this by managing an intelligent local cache, but understanding how it updates after mutations is key to a seamless user experience. This text-only course guides you through the core mechanics of Apollo Client's cache, showing you how to leverage automatic updates and manual cache manipulations to build highly responsive applications. What you'll learn: • Understand how Apollo Client normalizes and stores query results in its local cache. • Configure mutations to trigger automatic cache updates using unique identifiers. • Implement cache update functions for complex scenarios like adding or deleting items. • Apply modern cache policies to control how and when data is fetched. • Integrate cache updates with modern React hooks and TypeScript for type-safe state management. We begin with key terminology and foundational concepts of cache normalization before advancing to practical, text-based scenarios that illustrate real-world data flow. This course is designed for web developers with a basic understanding of GraphQL who want to master client-side state.
