Single geocoding

const Geocodio = require('geocodio-library-node');
const geocoder = new Geocodio('YOUR_API_KEY');
// const geocoder = new Geocodio('YOUR_API_KEY', 'api-hipaa.geocod.io'); // optionally overwrite the API hostname

Batch geocoding

To batch geocode, simply pass an array of addresses or coordinates instead of a single string

geocoder.geocode([
      '1109 N Highland St, Arlington VA',
      '525 University Ave, Toronto, ON, Canada',
      '4410 S Highway 17 92, Casselberry FL',
      '15000 NE 24th Street, Redmond WA',
      '17015 Walnut Grove Drive, Morgan Hill CA'
  ])
  .then(response => { ... })
  .catch(err => { ... });

geocoder.reverse([
      '35.9746000,-77.9658000',
      '32.8793700,-96.6303900',
      '33.8337100,-117.8362320',
      '35.4171240,-80.6784760'
  ])
  .then(response => { ... })
  .catch(err => { ... });

// Optionally supply a custom key that will be returned along with results
geocoder.geocode({
      'MyId1': '1109 N Highland St, Arlington VA',
      'MyId2': '525 University Ave, Toronto, ON, Canada',
      'MyId3': '4410 S Highway 17 92, Casselberry FL',
      'MyId4': '15000 NE 24th Street, Redmond WA',
      'MyId5': '17015 Walnut Grove Drive, Morgan Hill CA'
  })
  .then(response => { ... })
  .catch(err => { ... });

Field appends

Geocodio allows you to append additional data points such as congressional districts, census codes, timezone, ACS survey results and much much more.

To request additional fields, simply supply them as an array as the second parameter

geocoder.geocode(
      [
          '1109 N Highland St, Arlington VA',
          '525 University Ave, Toronto, ON, Canada'
      ],
      [ 'cd', 'timezone' ]
  )
  .then(response => { ... })
  .catch(err => { ... });

geocoder.reverse('38.9002898,-76.9990361', ['census2010'])
  .then(response => { ... })
  .catch(err => { ... });

Address components

For forward geocoding requests it is possible to supply individual address components instead of a full address string. This works for both single and batch geocoding requests.

geocoder.geocode({
      street: '1109 N Highland St',
      city: 'Arlington',
      state: 'VA',
      postal_code: '22201'
  })
  .then(response => { ... })
  .catch(err => { ... });

geocoder.geocode([
      {
          street: '1109 N Highland St',
          city: 'Arlington',
          state: 'VA'
      },
      {
          street: '525 University Ave',
          city: 'Toronto',
          state: 'ON',
          country: 'Canada',
      },
  ])
  .then(response => { ... })
  .catch(err => { ... });

Limit results

Optionally limit the number of maximum geocoding results by using the third parameter on geocode(...) or reverse(...)

// Only get the frst result
geocoder.geocode('1109 N Highland St, Arlington, VA', [], 1)
  .then(response => { ... })
  .catch(err => { ... });

// Return up to 5 geocoding results
geocoder.reverse('38.9002898,-76.9990361', ['timezone'], 5)
  .then(response => { ... })
  .catch(err => { ... });
