Area Codes

Get the city and state of all (as far as we know) U.S. and Canada area codes and North American Toll-Free Numbers. Look them up one phone number at a time, or dump the entire DB object.

Area code data is relatively small, so this library stores the data internally, and loads it into memory. No web service calls or anything like that. It's fast baby.

Memory impact should be < 100KB.

Usage

Pull by phone number (include country code or not, but only 1, United States/Canada, is supported). Also, many phone number formats are supported:

+1-###-###-####
1-###-###-####
###-###-####
+1 (###) ###-####
1 (###) ###-####
(###) ###-####
+1.###.###.####
1.###.###.####
###.###.####
+1##########
1##########
##########
etc.

Basically, if there are 10-11 digits (first digit being 1 if 11) in the format, it should parse fine.

let AreaCodes = require( 'areacode-city-states' );

let areaCodes = new AreaCodes();

areaCodes.get( '+1-303-123-4567', function( err, data ) {
	console.error( 'city/state/GPS', data );
} );

/** output:
{
  "type": "local", 
  "city": "Aurora",
  "state": "Colorado",
  "stateCode": "CO",
  "country": "US",
}
*/

Get entire DB:

let AreaCodes = require( 'areacode-city-states' );

let areaCodes = new AreaCodes();

areaCodes.getAll( function( err, data ) {
	console.error( 'all area codes', data );
} );

Contribute

If you want to help contribute to the library, this is how development goes. In all cases, make sure that you only add new test cases to the test suite in the test directory. The only time we should consider deleting/editing old test cases is if we are doing a non-backward compatible change.

Make sure your pull-requests go to the develop branch only.

Just editing lib/areacode-city-states.js

If you are just changing the code for how the in-memory database is loaded and accessed, you are only going to need to edit the lib/areacode-city-states.js file. And, you will only need to run npm test to verify your changes.
