User Guide

The haka_mqtt package is reliable “weapons grade” MQTT client library. It contains a core mqtt reactor class built with provable reliability, and reproducibility as its fundamental goals. A side effect is that the library turns out to be speedy as well.

The core reactor takes some time to plumb into an application event loop. To make life easier for simple use cases haka-mqtt includes a number of front-ends that speed implementation by making some reasonable assumptions. If these assumptions do not hold for application then it best to use the core reactor directly.
