Installation

npm i nikcli-tui

​
Import

import { Tooltip, Box } from 'nikcli-tui';

​
Quick Start

const target = new Box({ parent: screen, top: 1, left: 2, width: 12, height: 3, borderStyle: 'line', label: 'Hover' }).el;
new Tooltip({ parent: screen, content: 'Hello', target });

​
Production Examples

new Tooltip({ parent: screen, content: 'Top', target, position: 'top' });

​
Best Practices

  • Evita tooltip persistenti; usa hideDelay basso per UI reattiva.
