Usage

Parsing user-agent

In html, load woothee.js and call woothee.parse() directly.

<script src="./your/own/path/woothee.js"></script>
<script>
woothee.parse('Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)')
// => {name: 'Internet Explorer', category: 'pc', os: 'Windows 7', version: '8.0', vendor: 'Microsoft'}
</script>

In node.js code, require 'woothee' and call its parse().

var woothee = require('woothee');
woothee.parse('Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)')
// => {name: 'Internet Explorer', category: 'pc', os: 'Windows 7', version: '8.0', vendor: 'Microsoft'}

Parse user-agent string and returns a object with keys name, category, os, version and vendor.

For unknown user-agent (or partially failed to parse), result objects may have value 'UNKNOWN'.

  • category
    • labels of user terminal type, one of 'pc', 'smartphone', 'mobilephone', 'appliance', 'crawler' or 'misc' (or 'UNKNOWN')
  • name
    • the name of browser, like 'Internet Explorer', 'Firefox', 'GoogleBot'
  • version
    • version string, like '8.0' for IE, '9.0.1' for Firefix, '0.2.149.27' for Chrome, and so on
  • os
    • ex: 'Windows 7', 'Mac OSX', 'iPhone', 'iPad', 'Android'
    • This field used to indicate cellar phone carrier for category 'mobilephone'
  • vendor
    • optional field, shows browser vendor

Finding crawlers (almost all, not all) in fast

woothee.is_crawler('Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)')
 // => false

Try to see useragent's category is 'crawler' or not, by casual(fast) method. Minor case of crawlers is not tested in this method. To check crawler strictly, use woothee.parse(str).category === 'crawler'.
