[GraphQL] Use GraphQL's Object Type for Basic Types

We can create the most basic components of our GraphQL Schema using GraphQL‘s Object Types. These types allow us to group related fields together under a specific type, such as a Video or a User, and then allows us to fetch these types when we query our schema. In this video, we‘ll learn how to write GraphQL Object Types in GraphQL‘s Schema language, as well as how to create resolvers for them, and ultimately how to query them.

We are going to refactor this code to make it more readable and meanful:

const { graphql, buildSchema } = require(‘graphql‘);

const schema = buildSchema(`
    type Query {
        id: ID,
        title: String,
        duration: Int,
        watched: Boolean
    }

    type Schema{
        query: Query
    }
`);

const resolvers = {
    id       : () => ‘1‘,
    title    : () => ‘bar‘,
    duration : () => 180,
    watched  : true
};

const query = `
    query myFirstQuery {
        id,
        title,
        duration,
        watched
    }
`;

graphql(schema, query, resolvers)
.then((result) => console.log(result))
.catch(console.error)

‘id‘, ‘title‘, ‘duration‘, ‘watched‘ are video related. So we create a Video type.

const { graphql, buildSchema } = require(‘graphql‘);

const schema = buildSchema(`
    type Video {
        id: ID,
        title: String,
        duration: Int,
        watched: Boolean
    }

    type Query {
        video: Video
    }

    type Schema{
        query: Query
    }
`);

const resolvers = {
    video : () => ({
        id       : ‘1‘,
        title    : ‘bar‘,
        duration : 180,
        watched  : true
    })
};

const query = `
    query myFirstQuery {
        video {
            id,
            title,
            duration,
            watched
        }
    }
`;

graphql(schema, query, resolvers)
.then((result) => console.log(result))
.catch(console.error)
