Coroutines and Rx: A Battle Towards Asynchronicity
summary
Compares RxJava and Kotlin coroutines with concrete tradeoffs: Retrofit now supports suspend functions so coroutines win simple HTTP calls with no adapter, while Rx adds 11,000 methods vs coroutines’ ~3,000 methods so dex and learning costs differ. Covers exception behavior (launch vs async, coroutine exception handler, supervisorScope), shows how continuations resume suspend functions, and demonstrates a custom zip implementation for coroutines (works but needs extra code and doesn’t scale as easily as Rx’s built‑in zip). Flows bridge reactive patterns for state and UI streams.
