Firefox Accounts GeoDB Repo for Geolocation based services

Provides a wrapper around node-maxmind for getting the location data in an easy-to-read format.

Getting started

Install the module by running npm install fxa-geodb --save. Then, include the module in your source file, like so:

var geoDb = require('fxa-geodb')();

You can also pass other options like the path to the database to the require statement, like so:

var geoDb = require('fxa-geodb')({
  dbPath: 'cities-db.mmdb' // Defaults to fxa-geodb/db/cities-db.mmdb
});

API

The function returns a location object or throws if the ip was invalid or location data could not be found. Call the function like so:

try {
  const location = geoDb(ip);
  // Use location...
} catch (err) {
  // Handle err
}

The location object has the following properties:

• accuracy: Accuracy radius in km (number)
• city: Human readable city name (string)
• state: Human readable state name (string)
• stateCode: ISO 3166-2 state code (string)
• country: Human readable country name (string)
• countryCode: ISO 3166-1 alpha-2 country code (string)
• continent: Human readable continent name (string)
• timeZone: IANA tz database timezone (string)
• latLong: An object containing two properties:
  • latitude: Latitude (number)
  • longitude: Longitude (number)

For example:

{
  accuracy: 5,
  city: 'Mountain View',
  state: 'California',
  stateCode: 'CA',
  country: 'United States',
  countryCode: 'US',
  continent: 'North America',
  timeZone: 'America/Los_Angeles'
  latLong: {
    latitude: 37.3885,
    longitude: -122.0741
  }
}

A working example is provided in the examples directory.

# Test only src/test/lib/sentry.spec.ts
npx mocha test/fxa-geodb.js

# Grep for "setupDownloadList"
npx mocha /test/** -g "setupDownloadList"

Refer to Mocha's CLI documentation for more advanced test configuration.

Updating

A Cron job is provided in lib/maxmind-db-downloader, that can be configured and run like so:

  var maxmindDbDownloader = new MaxmindDbDownloader();
  var targetDirPath = maxmindDbDownloader.createTargetDir('db-name');
  var downloadPromiseFunctions = maxmindDbDownloader.setupDownloadList(
    path.join(__dirname, '..','path-to-sources-file'),
    targetDirPath
  );
  maxmindDbDownloader.setupAutoUpdate('30 30 1 * * 3', downloadPromiseFunctions);

By default, the cron job runs every week on Wednesday at 01:30:30 (UTC -7) and updates the Geodata-DB from Maxmind.
