## What it is
UniRx is a reimplementation of .NET Reactive Extensions for Unity, enabling composable asynchronous and event-based programming with LINQ-style operators. It adds Unity-specific utilities like ObservableTriggers and ReactiveProperty, and works across PC, mobile, WebGL, and other Unity platforms.

## Use cases
- handle async operations in Unity without coroutines
- compose Unity game loop events as reactive streams
- convert uGUI UI events to observable sequences
- detect double clicks or time-based event patterns
- run multithreaded work safely with Unity GameObjects
- replace WWW/Coroutine networking with composable async code

## When to choose
- maintaining an existing Unity project already built on UniRx
- you need Rx on older Unity versions or IL2CPP/iOS compatibility
- you want Unity-specific triggers and ReactiveProperty utilities

## When to avoid
- starting a new Unity project - the author recommends Cysharp/R3 instead
- you need async/await integration - use Cysharp/UniTask
- non-Unity .NET projects - use the official System.Reactive

## Facets
- artifact type: library

- domain: programming-languages, developer-tools
- platform: cross-platform, game-engine, cpp
