floating-ui-tooltip

A tooltip creation library built on top of floating-ui (unofficial)

Installation

npm install floating-ui-tooltip

Usage

import floatingTooltip from 'floating-ui-tooltip';

//...
const props = {
    content: 'tooltip body',
    // ...
}
const tooltipInstance = floatingTooltip(target, props);

floatingTooltip takes 2 arguments: target (type: HTMLElement) and props (type: Props) target is the HTML element we want the tooltip on.

Props

Props is an object with the following properties:

content

Type: string | Element

Default: ''

Content for tooltip element.

allowHTML

Type: boolean

Default: true

If to append content as an HTML element to the tooltip.

arrow

Type: boolean

Default: true

Whether we want an arrow from tooltip pointing to the target element.

transitionDuration

Type: number | [number | null, number | null]

Default: [300, 250]

First item in the array is the CSS property transition-duration when hiding the tooltip and second is when showing it.

offset

Type: [number | undefined, number | undefined]

Default: [0, 0]

Offset's data type is an array of 2 numbers, the first number is the distance of the tooltip from x-axis of the element, and the second number is the distance of tooltip from y-axis of the target element.

factorArrowInOffset

Type: boolean

Default: true

When set to true, the offset will be the one passed in offset combined with the size of the arrow element.

hideOnClick

Type: boolean | target

Default: true

If set to true: Clicking anywhere on the dom will hide the tooltip If set to target: Clicking on tooltip element will hide the tooltip

onClickOutside()

Type: (instance: Instance, event: MouseEvent) => void

Default: (instance: Instance, event: MouseEvent) => {}

Runs when click event is registered outside the tooltip or the reference element.

onShow()

Type: (instance: Instance) => void

Default: (instance: Instance) => {}

Runs when tooltip is shown.

onHide()

Type: (instance: Instance) => void

Default: (instance: Instance) => {}

Runs when tooltip is hidden.

onStateChange()

Type: (oldState: TooltipState, newState: Partial<TooltipState>) => void

Default: (oldState: TooltipState, newState: Partial<TooltipState>) => {}

Method that runs on tooltip state change.

onRemove()

Type: () => void

Default: () => {}

Method that runs on calling the remove() method on tooltip.

onBeforeFirstRender()

Type: () => void

Default: () => {}

Runs right before the tooltip is created in the dom.

onAfterFirstRender()

Type: () => void

Default: () => {}

Runs right after the tooltip is created in the dom.

placement

Type: Placement

type Position = FUIPlacement | 'auto';
type Orientation = 'fixed' | 'auto';

type Placement = {
  position: Position;
  orientation: Orientation;
}

Default:

{
    position: 'top',
    orientation: 'fixed'
}

Position

position dictates where the tooltip should be positioned with respect to the target dom element. The default value is bottom.

Orientation

Setting orientation to auto will make Lusift change the position of the tooltip if the tooltip overflows the document when rendered with the passed position value. Setting it to fixed prevents this behaviour. Default value is auto.

resetPlacementOnUpdate

Type: boolean

Default: false

hideOnTooltipEscape

Type: boolean

Default: true

If set to true, the tooltip will dissapear when it is out of the viewport.

hideOnReferenceHidden

Type: boolean

Default: true

If set to true, the tooltip will dissapear when the target element is out of the viewport.

showOnCreate

Type: boolean

Default: true

On true, the tooltip will show upon creation.

scrollIntoView

Type: boolean

Default: false

When set to true the document will scroll to the target element on the screen.

maxWidth

Type: number

Default: 350

Maximum width of the tooltip.

arrowSizeScale

Type: number

Default: 1

arrowSizeScale is the multiple value you want to increase the tooltip arrow's size by.

updateDebounce

Type: number

Default: 100

Set a limit to how frequently the update method can be triggered. Unit is milliseconds.

zIndex

Type: number

Default: 99999

z-index of the tooltip element.

updateOnEvents

Type: number

Default: resize scroll

Events seperated by spaces that should trigger tooltip update.
