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
geocoder
.geocode('1109 N Highland St, Arlington, VA')
.then(response => {
console.log(response);

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 => { ... });
Lists
List methods are nested within .list
. To access list methods, be sure to to run geocoder.list
and then include the task method you would like to utilize.
Create A List
To create and upload a new list using an existing .CSV file, run geocoder.list.create(...)
and pass in your filename/file path.
You may also need to pass in some additional parameters:
- Direction: Use the default string
"forward"
. - Format: Use the default string
"{{A}} {{B}} {{C}} {{D}}"
- Callback: A callback URL.
geocoder.list.create(
`${__dirname}/stubs/sample_list.csv`,
"forward",
"{{A}} {{B}} {{C}} {{D}}",
"https://example.com/my-callback"
)
Get List Status
To retrieve the current status of your list, pass your list's ID into geocoder.list.status(...)
.
geocoder.list.status(1234567)
.then(response => { ... })
.catch(err => { ... });
Get All Lists
To retrieve all available lists, run geocoder.list.all()
. You do not need to pass anything into this function.
geocoder.list.all()
.then(response => { ... })
.catch(err => { ... });
Download A List
To download a list, run geocoder.list.download(...)
and pass in the ID of the list you'd like to download, as well as a string that includes a filename. Be sure to include a .csv
file extension.
geocoder.list.download(1234567, "geocoded_file.csv")
.then(response => { ...})
.catch(err => { ... });
Delete A List
To delete a list, run geocoder.list.deleteList(...)
and pass in the ID of the list you'd like to delete.
geocoder.list.delete(1234567)
.then(response => { ... })
.catch(err => { ... });
