Modular Reactive Extensions for JavaScript RxJS

Reactive Extensions for JavaScript (RxJS) composed entirely of small modules.

The intent for this project is to make each operator available as its own export. For example, one could map and filter a given source such as the following:

var map = require('rx.observable.map');
var filter = require('rx.observable.filter');
var ofItems = require('rx.observable.of');

var source =
  filter(
    map(
      ofItems(1,2,3,4,5),
      function (x, i, o) {
        return x * x + i;
      }),
    function (x, i, o) {
      return x % 2 === 0;
    }
  );

source.subscribe(
  function (x) {
    console.log('Next', x);
  });

// => Next 2
// => Next 10
// => Next 26

Alternatively, you can chain them together very easily such as the following.

var Observable = require('rx.observable');
var map = require('rx.observable.map');
var filter = require('rx.observable.filter');
var ofItems = require('rx.observable.of');

Observable.prototype.map = function (selector, thisArg) {
  return map(this, selector, thisArg);
};
Observable.prototype.filter = function (predicate, thisArg) {
  return filter(this, predicate, thisArg);
};
Observable.of = function () {
  ofItems.call(null, arguments);
};

var source = Observable.of(1,2,3,4,5)
  .map(function (x, i, o) {
    return x * x + i;
  })
  .filter(function (x, i, o) {
    return x % 2 === 0;
  });

source.subscribe(
  function (x) {
    console.log('Next', x);
  });

// => Next 2
// => Next 10
// => Next 26
