Installation
Kefir available as NPM and Bower packages, as well as simple files download.

Browsers support
We don't support IE8 and below, aside from that Kefir should work in any browser.
Flow
The NPM package ships with Flow definitions. So you can do something like this if you use Flow:
// @flow
import Kefir from 'kefir'
function foo(numberStream: Kefir.Observable<number>) {
numberStream.onValue(x => {
// Flow knows x is a number here
});
}
const s = Kefir.constant(5);
// Flow can automatically infer the type of values in the stream and determine
// that `s` is of type Kefir.Observable<number> here.
foo(s);
