| --- | redux-observable | redux-saga |
|---|---|---|
| Style | Nested pipelines, need to reason how many times you need to "unpack" an Observable | Synchronous-looking code; can be deceiving |
| Learning curve | Several operators, though simple API. The reasoning is not straight-forward | Small set of effects, API almost inexistent besides the operators themselves |
| Async primitives | Introduces the Observable primitive, which unifies all async APIs. Perfect ergonomy for streamings. | Uses promises and event channels (API similar to Observable). There's no built-in solution for streamings, but it's not difficult to write one using the effects. |
| Extensability | Easy to create new operators and new adapters for custom async operations that are not yet adapted | Easy to use existing effects with custom promises, but it's not possible to create new effects |
| Browser support | ReactiveX/rxjs#998 | Couldn't find; probably the same as the generator transpiler https://facebook.github.io/regenerator/ |
| Documentation | Kinda confusing, there's a general Rx documentation and a specific for RxJS. The easiest way to understand the operators is through the RxJS Marbles website. | Extensive and clear documentation with several practical examples. |
| Community | Smaller redux-observable community, but giant Rx community. | The standard solution for advanced async patterns for the redux community. |
| Sponsors | Microsoft and Google (standard dependency in Angular). | No big sponsors (the biggest is Rollbar). |
| Usefulness outside of the scope of the application | Uses Rx with principles of functional programming | Uses go-like CSP model |
