random-ua.js - A random User-Agent Generator

Randomly generates User-Agent strings based on actual usage statistics from Wikipedia and StatOwl.com as of July 2012.

Caveats

The version numbers generated are sane, however, revisions are totally random and unlikely to exist in the wild.

I decided not to include language selection found in the PHP version and instead include all the languages in the ISO639-2 standard because it's atypical for sites to determine client locale based on the user-agent.

Usage

var random_ua = require('random-ua');

console.log(random_ua.generate());
//Easy like Sunday morning

//You can easily use random_ua to generate a random User-Agent for an HTTP request:

var http = require('http');

http.get({
        host:'whatsmyuseragent.com',
        path:'/',
        headers:{
            'User-Agent':random_ua.generate()
        }
    },
    function (res) {
        if (res.statusCode === 200) {
            var body = [];
            res.setEncoding('utf8');
            res.on('data', function (chunk) {
                body.push(chunk);
            });
            res.on('end', function () {
                body = body.join('');
                console.log(body);
            });
        } else {
            console.log('Error retrieving page: ' + res.statusCode);
        }
    }
);
