Getting started with React Query and GraphQL

In this article, we discuss strategies for implementing GraphQL with React Query. We start by updating our base example to include an input field that lets users provide HEX colors and receive a complementary color scheme automatically returned. We then explore two methodologies for updating content in React Query: invalidating cache and subscriptions. Invalidating cache involves calling a cache invalidation call after successfully updating from the server, while subscriptions allow us to update results when they become available. We demonstrate how to create a useColorSubscription hook that implements graphql-ws and updates React Query's cache on successful message reception. We also refactor our main application code to loop over this cache and handle asynchronous content more efficiently. Additionally, we introduce GraphQL Codegen for generating TypeScript types from GraphQL schemas and using them with React Query hooks. By following these strategies, developers can effectively manage their applications' data fetching and caching processes while leveraging the power of GraphQL subscriptions.
