You don't need a greenfield project to start with GraphQL. In this workshop, you'll build a GraphQL API that wraps existing REST endpoints, the most common real-world adoption path that tutorials almost never cover. We'll work through exposing REST resources as GraphQL types without 1:1 mapping, batching and deduplicating upstream REST calls using DataLoaders, handling authentication passthrough from GraphQL to downstream services, adding fields that aggregate data from multiple REST endpoints into a single query, and implementing pagination that translates between REST offset patterns and GraphQL cursor conventions. Bring a public REST API you work with (or use the one we provide) and leave with a working GraphQL layer sitting in front of it. You'll also walk away with a decision framework for which endpoints benefit most from a GraphQL wrapper, and which ones to leave alone.
