Reactive Extensions v2.2.24

This is another minor release of the Reactive Extensions for JavaScript which contains mostly bug fixes as we move towards version 2.3. This release includes some great stuff including a complete build (minus the testing), RxJS Lite Extras, and some fixes to behaviors such as with finally.

RxJS Complete Build

One feature that was requested often was to have a complete build of all RxJS operators in a single file, so that you don't have to hunt down which file contains the desired operator. This is good for prototyping where you are undecided about which operators you are going to use. Later on, you may decide you may need only a subset which might be only in rx.lite.js. The only parts that are not included in this file are for testing, which you can easily reference yourself.

To that end, we now ship rx.all.js for modern browsers and rx.all.compat.js for older browsers.

RxJS Lite Extras

Another requested feature was for the ability to include the operators that were included in the main rx.js file, but not included in rx.lite.js. We have created rx.lite.extras.js which contains the missing operators, which makes including other files such as rx.joinpatterns.js, rx.coincidence.js or others easier without worrying if something is missing.

The following operators included are:

Observable Methods

• amb
• onErrorResumeNext
• using

Observable Instance Methods

• amb
• bufferWithCount
• distinct
• groupBy
• groupByUntil
• observeOn
• onErrorResumeNext
• subscribeOn
• windowWithCount

Finally Behavior Fix

An issue was brought to our attention that if the subscribe is empty and an exception is thrown, the finally will not be called because there was no try/catch around the subscribe call. Below was the previous behavior which would not call the finally.

Rx.Observable.throw(new Error())
  .finally(function () { /* never would be hit */ })
  .subscribe();
// Error thrown

This has been corrected so we now get the expected behavior:

Rx.Observable.throw(new Error())
  .finally(function () { console.log('finally'); })
  .subscribe();

// => finally
// Error thrown

Removal of rxjs Node.js Module

A point of confusion was the existence of the rxjs Node.js module, which confused many as the official supported module is rx. We have since contact the author and it has been removed.
