Detect.js

Note: Detect.js is a JavaScript library to detect platforms, versions, manufacturers and types based on the navigator.userAgent string. This code is based on, and modified from, the original work of Tobie Langel's UA-Parser: https://github.com/tobie/ua-parser. UA-Parser is subsequently a port of BrowserScope's user agent string parser.

As initially touted, the biggest contribution to this code is the work of Steve Souders and the list of regex tests.

Features

• User-Agent parsing (obviously)
• AMD/Common.js support
• device, os and browser detection of:
  • name
  • family
  • version
  • major
  • minor
  • patch
  • device supports: manufacturer and type as well
• Custom regex builds using node.js

Creating a Custom Build

Creating a custom build of the regex profiles will help reduce file size and is strongly recommended. The default detect.js and detect.min.js files include all regex profiles and is therefor much larger then, I'm sure, your needs.

1. Install Node.js: https://github.com/joyent/node/wiki/Installation
2. Edit build/config.js with you're preferred oss, devices and browsers
3. Run node build/build.js --input=build/detect.js --output=build/detect.custom.js
4. The build script should create a custom version of Detect.js at build/detect.custom.js

Example Use

Plain JS:

<script src="detect.js"></script>

/*
iPhone 4 Example User Agent:
Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_0 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8A293 Safari/6531.22.7
*/

var ua = detect.parse(navigator.userAgent);

ua.browser.family // "Mobile Safari"
ua.browser.name // "Mobile Safari 4.0.5"
ua.browser.version // "4.0.5"
ua.browser.major // 4
ua.browser.minor // 0
ua.browser.patch // 5

ua.device.family // "iPhone"
ua.device.name // "iPhone"
ua.device.version // ""
ua.device.major // null
ua.device.minor // null
ua.device.patch // null
ua.device.type // "Mobile"
ua.device.manufacturer // "Apple"

ua.os.family // "iOS"
ua.os.name // "iOS 4"
ua.os.version // "4"
ua.os.major // 4
ua.os.minor // 0
ua.os.patch // null

Common.js:

var detect = require('detect');
var ua = detect.parse(navigator.userAgent);
...

Hacking

• Install development dependencies using npm install.
• Install the pre-commit hook by running hooks/install.sh.
• Kick off the default build (which will generate detect.js and detect.min.js) with npm start.
