vigour-ua

ua parser with a light footprint (~1kb)

parse user agent strings

var ua = require('vigour-ua')
var userAgent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.80 Safari/537.3'
console.log(ua(userAgent))

outputs

{
  "browser": "chrome",
  "version": 46,
  "prefix": "webkit",
  "platform": "mac",
  "device": "desktop"
}

merge into objects

var ua = require('vigour-ua')
var someObject = {
  randomField: true
}
console.log(ua(userAgent, someObject))

outputs someObject

{
  "browser": "chrome",
  "version": 46,
  "prefix": "webkit",
  "platform": "mac",
  "device": "desktop",
  "randomField": true
}

This useragent parser does not catch all useragents, if you encounter a device thats wrongly parsed add a test!
