Fermyon Spin is one of two WASM server platforms I’ve been experimenting with, and I felt limited by it’s restriction to using either HTTP or Redis to trigger the WASM components.

This plugin allows you to use a variety of message brokers as triggers - an in-memory broker, reds, NATs & MQTT. But beyond that, it also provides an HTTP gateway & WebSocket connectivity, allowing it to be used with those protocols as well.
