Bidirectional JS bridge for the native WebView component.

Use Mob.UI.webview/1 to embed the component, then call these functions from handle_info to communicate with the page.

JS side — inject window.mob is injected automatically by the native layer:

// Send a message to Elixir
window.mob.send({ event: "clicked", id: 42 })

// Receive a message from Elixir
window.mob.onMessage(function(data) { console.log(data) })

Elixir side:

def handle_info({:webview, :message, %{"event" => "clicked", "id" => id}}, socket) do
  {:noreply, socket}
end

def handle_info({:webview, :blocked, url}, socket) do
  # A navigation attempt was blocked by the allow: whitelist
  {:noreply, socket}
end
