It was 8 years ago when I made my first change to a GraphQL API. My next, real schema change came along a bit later and looked like this: name: { type: GraphQLString, }, + description: { + type: GraphQLString, + }, image: Image, artists: { type: new GraphQLList(Artist.type), We’re talking about the early days of GraphQL, and may even have pre-dated the Schema Definition Language (SDL) being in the spec.
