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.

@selectFires when an item, option, card, or result is selected.
@dataPointClickFires when the component emits the dataPointClick event.
@legendToggleFires when the component emits the legendToggle event.
Declarative handlers.wrn
<Chart
  @select='console.log(payload)'
  @dataPointClick='console.log(payload)'
  @legendToggle='console.log(payload)'
/>
Direct output handlers.js
import { registerOutputHandler } from "@wrnexus/csr/outputs"

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

if (component) registerOutputHandler(component, "select", (payload) => {
