GraphQLifying React Native App

Explore a comprehensive case study on migrating a large-scale React Native application with over 200,000 weekly users to Apollo Client 3.0 for data layer and state management. Learn about implementing a new backend GraphQL API to replace multiple separate API calls, utilizing local resolvers for REST APIs without GraphQL endpoints, and leveraging type policies with custom keyFields and cache references. Discover techniques for local state management using reactive variables for cache and performing cache updates with queries and cache.modify. Gain insights into the project's successful outcome, potential pitfalls encountered, and strategies for overcoming challenges. Delve into topics such as GraphQL playground, persistence, content blocks, enforcing response schemas, and React Native debugging with Devtools. Understand the implementation of mock providers and wrappers, and explore the overall architecture and API call structure of the migrated application.
