[GraphQL] Use GraphQL's List Type for Collections

In order to handle collections of items in a GraphQL Schema, GraphQL has a List Type. In this video, we’ll learn the syntax for specifying a List of items in a GraphQL Schema.

Quey list of videos:

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

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

    type Query {
        video: Video,
        videos: [Video]
    }

    type Schema{
        query: Query
    }
`);

const videos = [
    {
        id       : '',
        title    : 'react',
        duration : ,
        watched  : true
    },
    {
        id       : '',
        title    : 'relay',
        duration : ,
        watched  : false
    }
];

const resolvers = {
    video : () => ({
        id       : '',
        title    : 'bar',
        duration : ,
        watched  : true
    }),
    videos: () => videos
};

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

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