Abstract:
The goal of core.async is to decouple producers and consumers of information in software, without dictating specific thread or blocking semantics, and without introducing callback hell. Also, to do all of this as a library, portable anywhere you can run a dialect of Clojure.
Queues are a powerful tool for decoupling software programs. Unfortunately, platforms that have powerful queueing libraries (e.g. Java) may require blocking threads on the ends of the queue. And the world’s biggest platform (JavaScript in the browser) doesn’t even have queues or threads.
core.async builds upon the work done with Communicating Sequential Processes, and provides:
- facilities for independent threads of activity, communicating via queue-like channels
- both real threads and shared use of thread pools (in any combination), as well as ClojureScript on JS engines
