Intro to GraphQL
summary
GraphQL stitches together data from many microservices into one typed schema so clients ask for exactly the fields they need and get JSON shaped like the query. Coursera auto-generates GraphQL from existing REST APIs and maps fields to server resolvers that pull from different services. Clients like Apollo advanced caching avoid refetches by ID, Relay and Apollo power React components that declare fragments, and tools like GraphiQL in-browser explorer and codegen produce Flow/TypeScript types.
