Can you explain the key distinctions among Highland.js, Kefir.js, and Rx.js?

Given the emphasis on objective answers on SO, my inquiry is focused on understanding the distinct functional and performance characteristics of these three functional/reactive libraries. This knowledge will guide me in selecting the most suitable option among them. I have disregarded BaconJS due to its reliance on jQuery. As a newcomer to JS streams, my main goal is to gain a foundational understanding starting from NodeJS before transitioning into an AngularJS environment. If you have chosen one library over the others, what specific criteria influenced your decision?

Answer №1

It's all open to interpretation:)

RxJS

Advantages:

  • Extensive documentation and a large community support.
  • Shares interface with the Rx* family, allowing for easy adoption of RxJava samples.
  • Diverse range of primitives in the library with helpful usage examples.
  • Supports back-pressure.
  • Serves as a benchmark for other libraries.

Drawbacks:

  • Can appear overly complex at times.
  • Designed with a focus on "Java".

Bacon.js

Pros:

  • Comprehensive documentation with advanced sample projects like a snake game implementation.
  • Rich set of primitives available.
  • Developed with JavaScript in mind.
  • Easy for beginners to get started.

Cons:

  • Lacks support for back-pressure which limits backend applications.

Highland.js

Advantages:

  • Designed for use in node.js (or browserify) environments, offering seamless integration.
  • No unfamiliar concepts from a JavaScript/Node standpoint.
  • Provides support for back-pressure.
  • Built on top of Node streams, a clever approach.
  • Minimal footprint.

Drawbacks:

  • Poor documentation and lack of practical examples, making it challenging to understand without prior knowledge of Rx or Bacon.
  • Some primitives are missing, requiring manual implementation or adaptation from existing ones.

Summary: Due to limited sample resources, mastering each library is essential. In my opinion, Highland.js shows promise despite its shortcomings. However, RxJS remains a more mature option.

Tip: When seeking help on StackOverflow, consider using RxJS terminology and framing your query in simpler terms.

Answer №2

The repository for Reactive-Extensions contains pages where they compare RxJS to other libraries.
