Defined in:

lib/dommy/js/host_bridge.rb

Overview

An event listener backed by a live JS object implementing the EventListener interface (a handleEvent method, e.g. Stimulus's action listeners). Implements #handle_event so Dommy's invoke_listener routes to the object's handleEvent (with this bound to the object). Holds the JS-side ref so it also wraps back to the same JS object (identity kept).
