" summary

Shows a working Node.js + Express GraphQL server on port 4000 using Apollo Server Express and a Create React App frontend using Apollo Client (boost) and React hooks. Demonstrates schema types (non-null lists, scalars), queries vs mutations, resolver signature (parent, args, context), and that resolvers only run if fields are requested. Live examples: a hi query and a breweries→beers nested schema, using GraphQL Playground for interactive testing.
