Typescript: HTMLVideoElement is missing 'playsinline' attribute

[timmydoza]

TypeScript Version: 3.8.0

Search Terms:
HTMLVideo, HTMLVideoElement, playsinline
Code

const el = document.createElement('video');
el.playsinline = true; // Property 'playsinline' does not exist on type 'HTMLVideoElement'.

Expected behavior:

There should not be a TS error. playsinline is a boolean attribute that exists on the <video> element per https://html.spec.whatwg.org/multipage/media.html#htmlvideoelement

Actual behavior:

There is a TS error: Property 'playsinline' does not exist on type 'HTMLVideoElement'.

While the attribute is called playsinline, it is exposed as playsInline (capitalized "i") in the DOM.

I had the same problem too～,playsInline is ok!

yeah, remember that typescript uses cammelCase
like: autoplay should be autoPlay
and playsinline should be playsInline
