RxCpp is a header-only C++ library implementing Reactive Extensions, providing algorithms for composing asynchronous and event-based streams of values distributed in time. It depends only on the standard library and integrates via simple include paths or package managers like vcpkg and NuGet.

Use cases

• compose asynchronous event streams in C++
• handle values distributed over time reactively
• build reactive pipelines for UI or sensor events
• process streams of data with composable operators
• manage concurrency without manual thread coordination
• transform async callbacks into observable sequences

When to choose

• you need reactive/observable programming idioms in C++
• you want a header-only library with no external dependencies
• you are coordinating multiple asynchronous data sources or event streams

When to avoid

• your project is simple and synchronous with no async event handling
• you need actively developed features - the project is in maintenance mode
• you prefer coroutine-based async patterns over Rx-style operators
