zero-tooltip  

zero-tooltip is a Vue 3 simple tooltip component for displaying information text when hovering over element.

About

The component is designed to enhance user interactions by providing informative tooltips when hovering over specific element by rendering overlay with given text next to it. Components settings are fully customizable.

Install

# npm
npm install zero-tooltip

# yarn
yarn add zero-tooltip

# pnpm
pnpm install zero-tooltip

Register plugin and import styles in main.ts:

import ZeroTooltip from 'zero-tooltip'
import 'zero-tooltip/style.css'

const app = createApp(App)

app.use(ZeroTooltip)

Usage

Tooltip can be used with directive v-tooltip added on elements. The given value is displayed as tooltip's text:

<button v-tooltip="'Submits this form'">Submit</button>

Zero dependencies

This component does not depend on any other package, except Vue 3

Customization

Default position for tooltip is above/on top of the element that is being hovered. You can change position by passing argument to directive:

<button v-tooltip:right="'Submits this form'">Submit</button>

Acceptable arguments are: left | top | right | bottom. This will override tooltip default position that was set during plugin registering process.

You can also define default position globally when registering plugin:

app.use(ZeroTooltip, {
    defaultPosition: 'right'
})

Tooltip component is fully customizable by giving config object as options when registering tooltip plugin:

import ZeroTooltipConfig from 'zero-tooltip'

const tooltipConfig: ZeroTooltipConfig = {
    appendTo: ... ,
    defaultPosition: ... ,
    positions: ... ,
    offsetFromSource: ... ,
    offsetFromViewport: ... ,
    minWidth: ... ,
    maxWidth: ... ,
    tooltipBorderWidth: ... ,
    tooltipClasses: ... ,
    textClasses: ... ,
    arrowSize: ... ,
    arrowClasses: ... ,
    arrowMinOffsetFromTooltipCorner: ... ,
    zIndex: ...
}

app.use(ZeroTooltip, tooltipConfig)

All above settings are optional.

Tooltip can be customizable also for each usage (locally) using same config as follows:

<template>
    <button v-tooltip:right="tooltipConfig">Submit</button>
</template>

<script setup lang="ts">
import ZeroTooltipLocalConfig from 'zero-tooltip'

const tooltipConfig: ZeroTooltipLocalConfig = reactive({
    content: 'This is tooltip',
    appendTo: ... ,
    defaultPosition: ... ,
    positions: ... ,
    offsetFromSource: ... ,
    offsetFromViewport: ... ,
    minWidth: ... ,
    maxWidth: ... ,
    tooltipBorderWidth: ... ,
    tooltipClasses: ... ,
    textClasses: ... ,
    arrowSize: ... ,
    arrowClasses: ... ,
    arrowMinOffsetFromTooltipCorner: ... ,
    zIndex: ... ,
    show: ...
})
</script>

ZeroTooltipConfig

| Property | Default value | Type | Details | |---|---|---|---| | appendTo | body | string | A valid CSS query selector to specify where Tooltip gets appended. | | defaultPosition | top | TooltipPosition | Position of tooltip component relative to element that is being hovered. | | positions | {   left: ['left', 'right', 'top', 'bottom'],   top: ['top', 'bottom', 'right', 'left'],   right: ['right', 'left', 'top', 'bottom'],   bottom: ['bottom', 'top', 'right', 'left'], } | TooltipPositions | Ordered list of fallback positions in case tooltip does not have enough space in default position. If none of given positions will have enough space for tooltip, then it will not be rendered. | | offsetFromSource | 10 | number | Tooltip offset in px from element that's being hovered (arrow size is not added to this value) | | offsetFromViewport | 20 | number | Minimal allowed tooltip offset in px from viewport sides | | minWidth | 100 | number | Minimal tooltip width in px that will be allowed to render | | maxWidth | 250 | number | Maximal tooltip width in px that will be allowed to render | | tooltipBorderWidth | 0 | number | Tooltip container border width in px | | tooltipClasses | undefined | string | List of classes that will be added to tooltip element |
| textClasses | undefined | string | List of classes that will be added to text element | | arrowSize | 5 | number | Length of arrow hypotenuse in px (arrow is generated using border width property, creating square which gets divided in four triangles, thus arrowSize is length of square side) | | arrowClasses | undefined | string | List of classes that will be added to arrow element | | arrowMinOffsetFromTooltipCorner | 6 | number | Minimal allowed arrow offset in px from tooltip corner. Used in situations when tooltip does not have enough space to be centered relative to element that is being hover, thus arrow is rendered closer to one of the tooltip corners | | zIndex | 1 | number | string | z-index css property value of tooltip |
