import { GraphQLObjectType, GraphQLSchema } from 'graphql'
import { Point } from 'graphql-geojson-scalar-types'

export default new GraphQLSchema({
query: new GraphQLObjectType({
name: 'Query',
fields: () => ({
point: {
type: Point,
resolve: () => ({
type: 'Point',
coordinates: [-105.01621, 39.57422],
}),
