UI-Alert

Custom HTML element used to wrap a simple alert, composed by the slots: icon, message and hide. See demo

Usage

Instantiate the component that initializes the custom element.

import * as JSX from '@singleware/jsx';
import * as Alert from '@singleware/ui-alert';

const component = (
  <Alert.Component concealable open>
    <span slot="icon">👋</span>
    <span slot="message">This is an alert example initialized by the component wrapper.</span>
    <span slot="hide" />
  </Alert.Component>
) as Alert.Element;

Show and Hide programmatically.

component.show();
component.hide();

Be informed about the hide action.

component.addEventListener('hide', (event: Event) => console.log(`Yes! It's hidden now.`));
