We need to be able to allow onmouseover onmouseleave, etc via the custom JS api. See #40

This probably requires #92

Phoenix LiveView Implementation

https://hexdocs.pm/phoenix_live_view/js-interop.html

<div id="woot" phx-hook="HoverHook"/>

import { Socket } from "phoenix";
import { LiveSocket } from "phoenix_live_view";

// Register hooks here
let Hooks = {};
Hooks.HoverHook = {
  mounted() {
    console.log("Hook mounted!");
    this.el.addEventListener("mouseenter", () => {
      this.pushEvent("mouse_enter", { id: this.el.id });
    });
    this.el.addEventListener("mouseleave", () => {
      this.pushEvent("mouse_leave", { id: this.el.id });
    });
  }
};

// Initialize LiveSocket with hooks
let liveSocket = new LiveSocket("/live", Socket, {
  hooks: Hooks, // Hooks get passed here
});

def handle_event("mouse_enter", %{"id" => id}, socket) do
  IO.puts("#{id} was hovered!")
  {:noreply, socket}
end
