This library is no longer actively maintained. I will not be accepting any issues or pull requests. In the 5+ years since it was written, management of the source browscap.ini files changed and the characteristics of the data they provide changed significantly. In my own projects, I now use ua-parser which has libraries available in many languages.

Introduction

node-browscap is a port of PHP's get_browser function to node.js

It makes available a getBrowser function which takes a browser user agent string and returns an associative array of properties and abilities of that browser.

You must provide a browscap.ini file, which you can get here:

http://browsers.garykeith.com/downloads.asp

Both the browscap.ini or php_browscap.ini files should work.

Example:

var browscap = require('browscap');
browscap.setIni('./browscap.ini');

var browser = browscap.getBrowser("Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; WinTSI 05.11.2009)");

//Will print "IE 8.0"
console.log(browser['Browser'] + " " + browser['Version']);

Thanks to torvalamo for some rewrites to improve performance.

Installation

Using npm run npm install browscap

You can get npm from http://npmjs.org/

Alternatively you can clone the git repository

Examples

There is a test.js file which demonstrates how to use node-browscap and tests several user agents.

To run:

$ node test.js
