Question 1

How does Reagi compare to RxClojure for event handling?

Accepted Answer

Reagi is built on core.async and offers a more idiomatic Clojure approach with seq-like transformations, while RxClojure is based on Reactive Extensions with a richer operator set but steeper learning curve. Choose Reagi for tight core.async integration and RxClojure for advanced FRP features.

Question 2

How to avoid blocking when using event streams in Reagi?

Accepted Answer

Ensure event streams are always realized before dereferencing, or use core.async channels with `subscribe` to consume values asynchronously. The README notes that blocking occurs only when streams are unrealized, so pre-delivering values or sampling behaviors can mitigate this.

Question 3

What's the best way to dispose streams in ClojureScript with Reagi?

Accepted Answer

Call `reagi.core/dispose` on streams before they fall out of scope, as mentioned in the README differences. This prevents resource leaks, but requires careful lifecycle management, especially in single-page applications.

Question 4

Can Reagi be used with React-based UIs in ClojureScript?

Accepted Answer

Yes, Reagi's event streams can model UI state changes, but you'll need to handle integration manually or with libraries like re-frame. Its ClojureScript support allows reactive data flows, though manual disposal adds complexity.

Question 5

How to sample a behavior at a custom interval in Reagi?

Accepted Answer

Use the `sample` function with a millisecond interval, as shown in the README example. This converts continuous behaviors to discrete event streams, enabling periodic updates for applications like dashboards or real-time monitoring.

Question 6

Does Reagi support error handling in event streams?

Accepted Answer

Reagi relies on core.async's error mechanisms, so errors must be managed through channels or external patterns. The library doesn't provide built-in error recovery, which can be a limitation for robust systems.
