## Installation
```bash
npm i -S graphql-geojson
```
or with Yarn:
```bash
yarn add graphql-geojson
```
## Usage
```js
import { GraphQLObjectType, GraphQLSchema } from 'graphql'
import { PointObject } from 'graphql-geojson'
export default new GraphQLSchema({
query: new GraphQLObjectType({
name: 'Query',
fields: () => ({
point: {
type: PointObject,
resolve: () => ({
type: 'Point',
coordinates: [-105.01621, 39.57422],
crs: {
type: 'name',
properties: {
name: 'urn:ogc:def:crs:OGC:1.3:CRS84',
},
},
}),
},
}),
}),
})
```
Then you can query it like this:
```graphql
query {
point {
type
coordinates
crs {
type
properties {
... on GeoJSONNamedCRSProperties {
name
}
}
}
}
}
```
