graphql-geojson

library1.0.0jsnpmunverified

GraphQL schema object types for GeoJSON (v1.0.0). Provides GraphQL types for representing GeoJSON geometry objects (Point, LineString, Polygon, etc.) within a GraphQL schema. It integrates seamlessly with the reference GraphQL.js implementation. The library is mature and stable, but note that it is deprecated in favor of graphql-geojson-scalar-types for simpler scalar-based approach. Release cadence is low; no updates since 2017.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

PointObject

✓ import { PointObject } from 'graphql-geojson'

✗ const graphqlGeojson = require('graphql-geojson'); const PointObject = graphqlGeojson.PointObject;

ESM import is preferred; the package also supports CJS require.

LineStringObject

✓ import { LineStringObject } from 'graphql-geojson'

Same pattern for all geometry types.

GeoJSONInterface

✓ import { GeoJSONInterface } from 'graphql-geojson'

Used to define a union or interface for any GeoJSON type.

Shows how to define a GraphQL schema with a GeoJSON Point field using graphql-geojson.

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], }), }, }), }), }); // Run with: node -r esm server.js

Known issues

deprecatedPackage is deprecated. Use graphql-geojson-scalar-types for a scalar-based approach instead of object types.

fix

Replace with graphql-geojson-scalar-types or switch to custom scalar types.

affects: >=1.0.0

gotchagraphql-geojson defines object types (e.g., PointObject) that require explicit resolves for nested fields. This can lead to large schemas and complex resolvers.

fix

Consider using graphql-geojson-scalar-types which as a single custom scalar.

affects: >=1.0.0

gotchaThe library does not include a GeoJSON validation. Invalid input coordinates will be passed through without error.

fix

Manually validate GeoJSON inputs before storing or processing.

affects: >=1.0.0

Errors

Common errors & fixes

Cannot find module 'graphql-geojson'

Package not installed or missing from node_modules

fix

Run npm install graphql-geojson (and graphql as peer dep) from the project root.

TypeError: Cannot read properties of undefined (reading 'PointObject')

Incorrect import path or using a build tool that doesn't resolve the proper entry

fix

Use a named import: import { PointObject } from 'graphql-geojson'
