Generate relay connections by marking fields with a @connection directive.

// import connectionDirective from 'graphql-directive-connection'
import connectionDirective from './lib/index.js'
import { makeExecutableSchema, printSchemaWithDirectives } from 'graphql-tools'

const {
  connectionDirectiveTypeDefs,
  connectionDirectiveTransform,
} = connectionDirective('connection')

const typeDefs = `
  type User {
    userId: Int
    smallPosts: Post @connection
    posts: [Post!]! @connection
    bigPosts: [Post!]! @connection
  }

  type Post {
    postId: Int
  }

  type Query {
    user: User
  }
`

const schema = makeExecutableSchema({
  typeDefs: [connectionDirectiveTypeDefs, typeDefs],
})

const connectionSchema = connectionDirectiveTransform(schema)
const newTypeDefs = printSchemaWithDirectives(connectionSchema)
console.log(newTypeDefs)

/* console.log(newTypeDefs)

  query: Query
}
