Setting up GraphQL, Node/Express and PostgreSQL

다 좋은데 오래된 예제라 다음 두가지 수정이 필요하다.

(1) inside your schema.js as you create Object Type for String as

 fields: {
              name: {type: String} 
    }

GraphQL: Query.type field type must be Output Type but got: undefined

(2) Please replace your expressGraphQL with graphqlHTTP as it was destructured

Use:

const { graphqlHTTP } = require('express-graphql');

or

const expressGraphQL = require('express-graphql').graphqlHTTP
