IParty

Makes (geo) IP fun again! Ain't no party like an IParty, because an IParty don't stop.

IParty.fetch_db_files! # api key required
ip = IParty(request.remote_ip)

# all these are true
ip.country.de?
ip.country.germany?
ip.country.in_european_union?
ip.country.is_a?(Hash)
ip.country == "Germany" # 🤨

• IParty handles download* and decoding of, and lookup in, mmdb-files (* = shelling to curl and tar)
• IParty lets you annotate IPs/networks with arbitrary helpers, data and tags
• IParty lets you ignore the MAC address part of an ipv6 address more easily
• IParty has no* dependencies (* = stdlib dependencies: fileutils, forwardable, tmpdir, pathname, optparse)
• IParty is essentially a fork/refactor of the maxminddb gem. The reimaginated implementation details were however too party for a pull request in my opinion.
• IParty parties hard!

IParty ships with a cli utility iparty, refer to docs/cli/README.md for more information.

spec.required_ruby_version = ">= 3.2.0"

Install the gem and add to the application's Gemfile by executing:

bundle add iparty

If bundler is not being used to manage dependencies, install the gem by executing:

gem install iparty

These default settings should or could be changed at "boot" (i.e. in an initializer):

defined?(IParty) && IParty.configure do |config|
  config.account_id = config.env_value("MAXMIND_ACCOUNT_ID", nil)
  config.license_key = config.env_value("MAXMIND_LICENSE_KEY", nil)
end

There are more ways to configure and/or customize IParty. You can also change most of these settings via ENV variables.

See docs/configuration.md for more information.

Note: This requires a unix-oid environment with curl, tar and gzip available. You may change the download process. For more information see docs/configuration.md and docs/mmdb_download.md

Either in your application startup, and/or in a rake task:

IParty.fetch_db_files! # always download a fresh copy
IParty.fetch_db_files!(:missing) # only download missing files
IParty.fetch_db_files!(14 * 24 * 60 * 60) # only download missing or expired files (14.days also works with ActiveSupport)

You may also use the shipped rake tasks for this purpose:

rake iparty:fetch
rake iparty:fetch[14.days] # or int-seconds without AS
rake iparty:update

Outside of Rails you need to register them manually in your Rakefile:

require "iparty/rake_task"
IParty::RakeTask.new

ip = IParty("1.2.3.4") # shorthand for IParty.normalize
ip.as_json

# all these are true
ip.country.de?
ip.country.germany?
ip.country.in_european_union?
ip.country.is_a?(Hash)
ip.country == "Germany" # 🤨
ip.country == 123_345 # you may want to read the docs at this point lol
ip.country.names.de == "Deutschland"
ip.country.name(:es, fallback_locale: :fr) == "Germany"
ip.country.dig(:names, :en) == "Germany"

You should definitely take a quick look at the documentation, specifically about the MaxMine::Result object. It should be intuitive magic but you may scratch your head if you "don't get it".

• docs/mmdb_download.md

IParty is somewhat compatible with (read: replacing) maxminddb depending on your usage. Most notably the result data hash is symbolized.

• Check out the repository
• Run bin/setup to install dependencies
• Run bin/console to experiment with an interactive irb prompt
• Run rake to run all the tests
• Run rake ci to fetch mmdb-files, then run all the tests (more coverage)

In order to run all the tests you must have API credentials for MaxMind (or a mirror / local copy of the mmdb files for Country, City and ASN). The mmdb-files can no longer be distributed or downloaded without API credentials due to licensing. See Configuration.
