Local parser is very fast and accurate useragent string detection solution. Enables developers to locally install and integrate a highly-scalable product. We provide the detection of the devices (personal computer, tablet, Smart TV, Game console etc.), operating system, client SW type (browser, e-mail client etc.) and devices market name (example: Sony Xperia Tablet S, Nokia Lumia 820 etc.). It also provides information about IP addresses (Public proxies, VPN services, Tor exit nodes, Fake crawlers, Web scrapers, Datacenter name .. etc.)
- Tested with more the 50.000 unique user agents.
- Up to date data provided by https://udger.com/
- nodejs >= 8.9.0
- datafile v3 (udgerdb_v3.dat) from https://data.udger.com/
- Fast
- LRU cache
- Released under the MIT
npm install udger-nodejs
You should review the included examples in examples/ and test/ directory.
Here's a quick example:
const udgerParser = require('udger-nodejs')('./udgerdb_v3.dat');
udgerParser.set({
ua:'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36',
ip:'2A02:598:7000:116:0:0:0:101'
});
let ret = udgerParser.parse();
// beautify json output with 4 spaces indent
console.log(JSON.stringify(ret, null, 4));Result

By default, JSON Udger format is used. The JSON Udger format is coming from the PHP Parser (compatibility)
Others JSON format are available, by passing options in udger.parse() function.
