gatsby-source-googlemaps-geocoding

This source plugin for Gatsby will make location information from Google Maps available in GraphQL queries.

Installation

# Install the plugin
yarn add gatsby-source-googlemaps-geocoding

In gatsby-config.js:

module.exports = {
  plugins: [
    {
      resolve: 'gatsby-source-googlemaps-geocoding',
      options: {
        key: 'YOUR_GOOGLE_MAPS_GEOCODING_API_KEY',
        address: 'ADDRESS_YOU_ARE_GEOCODING'
      },
    }
  ]
};

NOTE: To get a Google Maps Geocoding API key, register for a Google Maps dev account.

Configuration Options

The configuration options for this plugin are currently a small subset of the geocoding API parameters. Please review those docs for more details and feel free to contribute to this repo to expand the accepted parameters.

Option	Default	Description
`key`		[required] Your application’s API key. This key identifies your application for purposes of quota management.
`address`		[required] The street address that you want to geocode, in the format used by the national postal service of the country concerned.

Example Configuration

module.exports = {
  plugins: [
    {
      resolve: 'gatsby-source-googlemaps-geocoding',
      options: {
        key: process.env.GOOGLE_MAPS_GEOCODING_API_KEY,
        address: `Boston, MA`
      }
    }
  ]
};

Querying Google Maps geocoding information

Once the plugin is configured, one new query is available in GraphQL: allLocationData.

Here’s an example query to load the latitude and longitude for Boston, MA:

query LocationQuery {
  allLocationData {
    edges {
      node {
        results {
          geometry {
            location_type
            location {
              lat
              lng
            }
          }
        }
      }
    }
  }
}

See the Google Maps Geocoding API docs or the GraphiQL UI for info on all returned fields.
