Rxjava To Coroutines Migration

new-silvermoon/awesome-android-agent-skills

If you're still dragging RxJava around in a Kotlin codebase, this handles the tedious conversion work to Coroutines and Flow. It maps Singles to suspend functions, Observables to Flows, and converts BehaviorSubjects to StateFlows with the standard idioms you'd find in any migration guide. The operator translations are solid, like flatMap to flatMapMerge and switchMap to flatMapLatest. It also rewrites subscriptions into proper coroutine launches with lifecycle scopes. Honestly most useful for teams stuck on legacy Android code who need to modernize without spending two sprints rewriting async layers by hand.

RxJava to Kotlin Coroutines Migration Skill

A specialized skill designed to safely and idiomatically refactor Android or Kotlin codebases from RxJava to Kotlin Coroutines and Flow.

Migration Mapping Guide

When migrating RxJava components to Kotlin Coroutines, use the following standard mappings:

1. Base Types

Single<T> -> suspend fun ...(): T
- A single asynchronous value.
Maybe<T> -> suspend fun ...(): T?
- A single asynchronous value that might not exist.
Completable -> suspend fun ...()
- An asynchronous operation that completes without a value.
Observable<T> -> Flow<T>
- A cold stream of values.
Flowable<T> -> Flow<T>
- Coroutines Flow natively handles backpressure.
