Cities is an easy to use Node.js library to allow you to lookup a city by it's zipcode or by a set of GPS coordinates.
Like any node.js application.
npm install
node server.js
You can then visit http://localhost:4000 with the endpoints /gps/:lat/:lng or /zip/:zipcode to get locations.
Easy. Require "cities": "1.x" in package.json, then do npm install.
var cities = require('cities');
cities.gps_lookup(lat, lng);
cities.zip_lookup(zipcode);
A sample response or object that this module returns looks like this.
{
zipcode: "07946",
state_abbr: "NJ",
latitude: "40.672823",
longitude: "-74.52011",
city: "Millington",
state: "New Jersey"
}
