The Big Ideas in Relay

Session description

Relay, Meta’s advanced GraphQL client for React, has many innovative capabilities not available in other clients. We will explore these capabilities, what they are, how they work, and the fundamental problems they solve: - Ensure data consistency with a normalized cache - Bound memory usage with user-land garbage collection - Avoid append-only queries by statically detecting unused fields - Bound JavaScript bundle size with Data Driven Dependencies - Build snappy, robust, mutations with rebasing optimistic updates - Preload code and data for any surface in just one network roundtrip with Entrypoints - Enable optimal data fetching without sacrificing local reasoning with Relay’s compiler And more!
