Local parser is very fast and accurate useragent string detection solution. Enables developers to locally install and integrate a highly-scalable product. We provide the detection of the devices (personal computer, tablet, Smart TV, Game console etc.), operating system, client SW type (browser, e-mail client etc.) and devices market name (example: Sony Xperia Tablet S, Nokia Lumia 820 etc.). It also provides information about IP addresses (Public proxies, VPN services, Tor exit nodes, Fake crawlers, Web scrapers, Datacenter name .. etc.)
- Tested with more the 10.000 unique user agents.
- Up to date data provided by https://udger.com/
Add this line to your application's Gemfile:
gem 'udger'And then execute:
$ bundle
Or install it yourself as:
$ gem install udger
User agent and ip parser for Udger db.
require 'udger'
parser = Udger::Parser.new('path_to_udger_db', options) # File must be named 'udgerdb_v3.dat'
- cache - default is true, enable caching results. Only available for user agent parsing.
- lru_cache_size - default is 10,000. How many objects to be cached.
- ua_services - if you do not need all the information for a user agent, you can specify which services to receive. Available services are: [:crawler, :client, :os, :device, :device_market]. Reducing the number of services will improve performances.
