GeoIP data for isitchristmas.com

This app uses the geoip-lite library to process GeoIP2 CSV files into a binary .dat format, that is then read in directly by the app.

Unfortunately, the process of doing this is a little complicated.

1. Buy the paid GeoIP2 country CSV from Maxmind.
2. Download the free GeoLite2 city CSV from Maxmind. (Just an implementation detail. Needed by the script as written, but not actually used for looking up user city.)
3. Remove the local data directory inside ./node_modules/geoip-lite, and symlink the data/ directory that this file resides in to be that data directory, so that the results of the update script drop the .dat files into this directory.
4. Update geoip-lite's update script to use/download these CSVs during its update process.
5. Run the update script, which should create/update geoip-city-name.dat, geoip-city.dat, geoip-city6.dat, geoip-country.dat, and geoip-country6.dat inside the /data directory.

The script expects the url field to point to an https:// URL. The easiest way to deal with this is to use a quick-and-dirty static file server (like http-server, a Node library) to run something on a port that serves the file for the script to download from. The below example uses http://localhost:5000.

If using this approach, you'll also need to make two edits to the update script to have it use http instead of https:

• Change the module include to use http, like so: var http = require('http');
• Change the client request line to use http, like so: var client = http.get(getOptions(), onResponse);

When the app is run, running require('geoip-lite') should use the .dat files to populate the database.

Implementation notes

Example of database object to use in updatedb.js:

var databases = [
  {
    type: 'country',
    url: 'http://localhost:5000/GeoIP2-Country-CSV_20241224.zip',
    src: [
      'GeoIP2-Country-Locations-en.csv',
      'GeoIP2-Country-Blocks-IPv4.csv',
      'GeoIP2-Country-Blocks-IPv6.csv'
    ],
    dest: [
      '',
      'geoip-country.dat',
      'geoip-country6.dat'
    ]
  },
  {
    type: 'city',
    url: 'http://localhost:5000/GeoLite2-City-CSV_20241224.zip',
    src: [
      'GeoLite2-City-Locations-en.csv',
      'GeoLite2-City-Blocks-IPv4.csv',
      'GeoLite2-City-Blocks-IPv6.csv'
    ],
    dest: [
      'geoip-city-names.dat',
      'geoip-city.dat',
      'geoip-city6.dat'
    ]
  }
];
