useVideoJs: a React Hooks for Video.js

The Video.js docs have a good explaination for using Video.js with React, but it focuses on a class based implementation. Getting Video.js to consistently work with React Hooks is fairly straight forward, with a gotcha or two.

Here's the hook:

import * as React from 'react'
import videojs from 'video.js'
import 'video.js/dist/video-js.css'
const useVideoJS = (videoJsOptions: any) => {
const videoNode = React.useRef(null)
const player = React.useRef<any>(null)
React.useEffect(() => {
player.current = videojs(videoNode.current, videoJsOptions)
return () => {
player.current.dispose()
}
}, [changedKey])
const Video = React.useCallback(
({children, ...props}) => {
return (
<div data-vjs-player key={changedKey}>
<video ref={videoNode} className="video-js" {...props}>
{children}
</video>
</div>
)
},
[changedKey],
)
return {Video, player: player.current}
}

The hook returns the Video component, which is memoized with useCallback. This is important! This approach gives us a stable component to use that only updates if the options have changed.

In the useEffect we are creating an instance of the player and that is also properly disposed of if the options change.

Now you can use it like this:

import * as React from 'react'
import {useVideoJs} from './use-video-js'
const MyComponent = () => {
const {Video} = useVideoJS({
poster: video.poster,
sources: [{src: video.url}],
controls: true,
playbackRates: [0.5, 1, 1.5, 2],
responsive: true,
})
return (
<Video poster={video.poster} playsInline muted>
<track
src={video.subtitlesUrl}
kind="subtitles"
srcLang="en"
label="English"
/>
</Video>
)
}
It makes me smile when I see it.
