Examples

Adding a toast

Use the addToast() function from the API to add a toast to the toast store.

If an onAction() or onDismiss() callback is provided, the implementer must call the passed in remove() function. If the onDismiss() callback is not provided, the toast is removed immediately.

const { toasterState, api }  = useToast(); 
const { addToast } = api;

addToast({
  type: 'error',
  message: 'An error occurred!',
  actionText: 'Retry',
  onAction: remove => {
    async attemptRetry();
    remove();
  },
  onDismiss: remove => {
    async doSomethingOnDismiss();
    remove();
  },
  icon: <Icon src={SadFaceIcon} />
});
