Versions (optional)

The versions allowed object are optional, if passed by, it should be an object:

import OldBrowserDetector from 'old-browser-detector';

const Detector = new OldBrowserDetector({ i: 11 });

You can detect an specified version for mobile users too:

Passing an object inside the browser object key, with keys d and m (desktop and mobile respectively), the library will detect the browser version according to the device the client is using:

import OldBrowserDetector from 'old-browser-detector';

const Detector = new OldBrowserDetector({ s: { d: 8, m: 3 } });

When you use that option, the two keys ('d' and 'm') are required

|Object Key |Default (Desktop) |Default (Mobile)|Browser | |----------------|------------------|----------------|-------------------------| |i |11 |11 | Internet Explorer | |f |20 |20 | Firefox | |c |20 |20 | Chrome | |o |10.6 |10.6 | Opera | |s |8 |3 | Safari | |n |10 |10 | Netscape |
