React-hint

React-hint is a small tooltip component for React which is developed with simplicity and performance in mind. It also plays nicely with Preact and Inferno.

How to install

npm i -S react-hint

How to use

// React
import React from 'react'
import ReactHintFactory from 'react-hint'
const ReactHint = ReactHintFactory(React)

// Preact
import {h, Component} from 'preact'
import ReactHintFactory from 'react-hint'
const ReactHint = ReactHintFactory({createElement: h, Component})

// Inferno
import Inferno from 'inferno-compat'
import ReactHintFactory from 'react-hint'
const ReactHint = ReactHintFactory(Inferno)

// UMD
const ReactHint = window.ReactHintFactory(window.React)

Example

You don't need to include ReactHint in every component which uses tooltips, just include it once in the topmost container component. In case you need to define multiple instances of ReactHint, you can customise the attribute name per instance. ReactHint also supports custom tooltip content with attached event handlers by overriding the content renderer and returning a react node.

import React from 'react'
import {render} from 'react-dom'
import ReactHintFactory from 'react-hint'
import 'react-hint/css/index.css'

const ReactHint = ReactHintFactory(React)
class App extends React.Component {
	onRenderContent = (target, content) => {
		const {catId} = target.dataset
		const width = 240
		const url = `https://images.pexels.com/photos/${catId}/pexels-photo-${catId}.jpeg?w=${width}`

		return <div className="custom-hint__content">
			<img src={url} width={width} />
			<button ref={(ref) => ref && ref.focus()}
				onClick={() => this.instance.toggleHint()}>Ok</button>
		</div>
	}

	render() {
		return <div>
			<ReactHint autoPosition events delay={100} />
			<ReactHint persist
				attribute="data-custom"
				className="custom-hint"
				events={{click: true}}
				onRenderContent={this.onRenderContent}
				ref={(ref) => this.instance = ref} />

			<button data-rh="Default">Default</button>
			<button data-rh="Top" data-rh-at="top">Top</button>
			<button data-rh="Right" data-rh-at="right">Right</button>
			<button data-rh="Bottom" data-rh-at="bottom">Bottom</button>
			<button data-rh="Left" data-rh-at="left">Left</button>

			<button data-custom
				data-custom-at="bottom"
				data-cat-id="10913">Click Me</button>

			<button data-custom
				data-custom-at="bottom"
				data-cat-id="416088">Click Me</button>
		</div>
	}
}
