Synopsis

Node.js module to return an object with location information from an IP address. This module can be used with various free location API's and will cache the information locally and(optionally) on Firebase to avoid hiting the API too frequently

API's tested:

http://telize.com/geoip/

http://ip-api.com/json/

Usage

Create a configuration variable.

var ip2dataConfig = {

  cache: {
    firebase: {
      firebaseUrl: [FIREBASE_URL]",
      firebaseKey: "[FIREBASE_KEY]",
      expiration: 72, // Expiration in hours
      keyname: "ipcache"  
    }, 

    local: {
      expiration: 72 // Expiration in hours
    }, 
        
  },

  IpApiEndpoint: "http://www.telize.com/geoip/", // make sure to end with "/"

}

Initialize ip2data module

var ip2data = require('ip2data')(ip2dataConfig)

Initiate the function passing the ip address. The result will be an object with informations such as city, latitude, longitude, depending on selected API.

ip2data(ip,function(error,result){

  console.log(result)

});

Motivation

Create an Angular app to show connected users in a map in real-time

Installation

npm install ip2data
