A sample subscription on an Order type

sampleSub.js

const gql from 'graphql-tag';

const onCreateOrderByCustomer = gql`
	mutation OnCreateOrder($orderCustomerId: ID) {
		onCreateOrder(orderCustomerId: $orderCustomerId) {
			id
			orderCustomerId
			customer {
				id
				name
			}
			barista {
				id
				name
			}
		}
	}
`;

mutation should be subscription
