Component outputs

Receive every typed component output

Use declarative output handlers in .wrn files or register a direct output handler from JavaScript. The canonical API exposes payload and does not require event.detail.

@dismissFires after the announcement or feedback surface is dismissed.
@actionFires when the component's primary or item action is activated.
Declarative handlers.wrn
<Alert
  @dismiss='console.log(payload)'
  @action='console.log(payload)'
/>
Direct output handlers.js
import { registerOutputHandler } from "@wrnexus/csr/outputs"

const component = document.querySelector("[data-ui-component=\"Alert\"], [data-component=\"Alert\"]")

if (component) registerOutputHandler(component, "dismiss", (payload) => {
  console.log("dismiss", payload)
})

if (component) registerOutputHandler(component, "action", (payload) => {
  console.log("action", payload)
})
