Relay Hooks are a set of React Hooks-based APIs that strives to simplify working with GraphQL data and improve the developer experience. Relay Hooks include APIs for fetching queries, loading data with fragments, pagination, refetching, mutations, and subscriptions. According to Balicki and Tejada, Relay Hooks offer sizeable advantages: fewer lines of code and less indirection than the equivalent container-based solution; more complete Flow and Typescript coverage; automation of error-prone tasks (refetch and pagination queries); fetch policy configuration; and lower experienced latency by fetching data before a component renders.
