{UAParser.js} detect Browser, Engine, OS, CPU, and Device type/model from User-Agent data with relatively small footprint (~17KB minified, ~6KB gzipped) that can be used either in browser (client-side) or node.js (server-side).
Now, detecting browser is as simple as ua.getBrowser()
UAParser.js has been upgraded to detect comprehensive device data based on the User-Agent and User-Agent Client Hints.
This package supports all device types including Apple and Android devices and can be used either in a browser (client-side) or Node.js environment (server-side).

{UAParser.js} abstracts away the hassle of User-Agent detection by turning them into a set of simple & meaningful data. As an example, this is what we get from your browser's User-Agent information:
{UAParser.js} reads this as:
It's widely known that User-Agent string as of today is a mess. On the other hand, there is no reliable way to identify browser. {UAParser.js} fills this gap by filtering the noise away and extracts only the most relevant data available: Browser, Engine, OS, CPU, and Device.
Started from JavaScript approach, {UAParser.js} is optimized to be used with browser. While it covers a vast range of detection, the size always kept to be as light as possible. For extra cache performance, {UAParser.js} also available in popular CDN services (jsDelivr/CDNJS).

Whether it's a client-side webpage running in a browser or a server-side node.js app, simply type:
$ npm i ua-parser-js --saveNo framework needed. No transpiler required. Just a good ol' ES3-compatible syntax that is able to run on relatively old browsers while also perform on most modern devices. Just insert the code and you're good to go.
Having large user base, whenever jQuery is present, {UAParser.js} will detect and generate $.ua plugin automatically. Also, for TypeScript user, there is a community-maintained typed: @types/ua-parser-js.
