A tooltip component for React apps utilizing the excellent popper.js library.
Installation

Usage
import Tooltip from '@cypress/react-tooltip'
<Tooltip title="Hello World">
<button>Click me</button>
</Tooltip>
The tooltip will automatically appear when mousing over the button and disappear when mousing out from the button.
Options

| title | undefined | Required. The tooltip content | Anything renderable by React (string, number, element, etc) |
| placement | 'top' | The placement of the tooltip | Placements supported by popper.js |
| visible | undefined | Whether to show the tooltip when rendered. This overrides the default showing/hiding on mouse-over/mouse-out | true or false |
| className | 'tooltip' | Class applied to the tooltip | |
