How to use

Go to http://cerebral-website.herokuapp.com/documentation/cerebral-module-useragent

User agent parser

I am using the ua-parser-js package to parse navigator.userAgent. Currently only the browser, device and OS parts are stored in the model, because I didn't see any use for cpu and engine.

Window

The window resize event is just slightly throttled using requestAnimationFrame(). I might make this configurable to use a stronger throttle timeout if it proofs to be too resource hungry.

Media queries

The media queries are tested with matchMedia() so you should be able to use any valid CSS media query.

Feature detection

I am using the feature.js package to detect browser features. Please checkout the website to see a list of all supported feature tests.

You can also only store certain test results in the model or define your own tests.

const useragent = Useragent({
  feature: {
    touch: true,
    serviceWorker: true,
    getUserMedia: () => !!navigator.getUserMedia
  }
})

All tests from feature.js are executed even if you set the feature option to false. This is a limitation of the library.

Network detection

I am using the offline-js package to detect internet connectivity. The application is initially assumed to be online.
