ua-parser

This module integrates Drupal 8 with ua-parser, an open-source and community-driven, regexp-based user-agent parser.

For more information about ua-parser, visit uaparser.org.

Installing

The module requires using Composer to manage Drupal site dependencies. Require the module via

$ composer require drupal/uaparser

then enable the module as usual.

Configuration

• Go to Manage > Configuration > System > ua-parser and update the user-agent definition file to the most recent version by clicking on the 'Update now' button.
• Select the 'Enable automatic updates' tickbox if you want automatic updates of the file, and the frequency of the updates.
• The 'USER-AGENT LOOKUP' part of the form allows to parse any user-agent string and display its results. By default it displays the results of the current request's user-agent string, but any string can be copy/pasted in the text field, and results displayed clicking on the 'Lookup' button.

Usage

The module by itself does not do much - it exposes a service that can be used to parse user-agent strings and return meaningful results. All the work is done by the ua-parser/uap-php library that the service integrates with.
The service however allows to cache user-agent strings and its results in a Drupal cache bin, to speed up lookups.
Also, the service manages updates of the user-agent definition file from the source ua-parser/uap-core library.

Basic code example:

$parser = Drupal::service('uaparser');
$parsed_ua = $parser->parse('Mozilla/5.0 (Windows NT 6.2; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0');
return ['#markup' => $parsed_ua['client']->toString()];

will return

Firefox 35.0/Windows 8

The $parsed_ua variable returned by the ::parse() method is an associative array containing the following keys:

• 'client' - an instance of the UAParserResultClient class with all the data parsed from the user-agent string;
• 'time' - the time in milliseconds the user-agent string required to be parsed.
