How to: Reactive libraries
_Libraries for developing reactive applications._

- [Akka](https://akka.io) - Toolkit and runtime for building concurrent, distributed, fault-tolerant and event-driven applications.
- [Reactive Streams](https://github.com/reactive-streams/reactive-streams-jvm) - Provides a standard for asynchronous stream processing with non-blocking backpressure.
- [Reactor](https://github.com/reactor/reactor) - A framework for building non-blocking applications on the JVM, providing support for reactive programming.
- [RxJava](https://github.com/ReactiveX/RxJava) - Allows for composing asynchronous and event-based programs using observable sequences.
- [vert.x](https://vertx.io) - Polyglot event-driven application framework.
