Example

The below type is a shorthand notation. The API is more expressive and allows types and fields to be documented. See the getting started schema starWarsSchema.js

• an enum

enum Episode { NEWHOPE, EMPIRE, JEDI }

• an interface

interface Character {
  id: String!  // ! means not null
  name: String
  friends: [Character]
  appearsIn: [Episode]
}

• types implementing ther interface

type Human implements Character {
  id: String
  name: String
  friends: [Character]
  appearsIn: [Episode]
  homePlanet: String
}

type Droid implements Character {
  id: String
  name: String
  friends: [Character]
  appearsIn: [Episode]
  primaryFunction: String
}

• The Entry point that defines the whole schema (by default, the name is Query)

type Query {
  hero(episode: Episode): Character
  human(id: String!): Human
  droid(id: String!): Droid
}
