# graphql-geojson-scalar-types

GraphQL schema scalar types for GeoJSON. Based on [GeoJSON Validation](https://gitlab.com/mjbecze/GeoJSON-Validation).

## Installation

```bash

npm i graphql-geojson-scalar-types

```

or

```bash

yarn add graphql-geojson-scalar-types

```

## Usage

```ts

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],

        }),

      },

      pointInvalid: {

        type: Point,

        resolve: () => ({

          type: 'Invalid',

          coordinates: [-105.01621, 39.57422],

        }),

      },

    }),

  }),

})

```

Then you can query it like this:

```graphql

query {

  point

  pointInvalid

}

```
