RxFiddle

RxFiddle is a debugger for Reactive Extensions (Rx).

Features

• visualises structure of Observables in graph diagram,
• visualises construction of and data flow through Observable sequences in Marble Diagrams,
• supports live fiddling with input streams,
• generates tests for Observable sequences.

Collectors

RxFiddle works by means of a visualizer and collectors which can parse syntax and instrument (compiled) code to collect the lifecycle of Observables:

• creation of Observable sequences
• subscriptions in a Observable sequence
• onNext, onError and onComplete events in Observable sequence

Existing collectors:

• JavaScript for RxJS
• JVM for RxJava, RxKotlin and RxScala
• Dalvik for Rx on Android
• Swift for RxSwift

Contribute

Every help is welcome improving RxFiddle, either by improving the visualiser or creating custom collectors for your favorite Rx-library.
