jsx_a11y/media-has-caption Correctness

✅ This rule is turned on by default.

What it does

Checks if <audio> and <video> elements have a <track> element for captions. This ensures media content is accessible to all users, including those with hearing impairments.

Why is this bad?

Without captions, audio and video content is not accessible to users who are deaf or hard of hearing. Captions are also useful for users in noisy environments or where audio is not available.

Example

Examples of incorrect code for this rule:

<audio></audio>
<video></video>

Examples of correct code for this rule:

<audio><track kind="captions" src="caption_file.vtt" /></audio>
<video><track kind="captions" src="caption_file.vtt" /></video>

How to use

To enable this rule in the CLI or using the config file, you can use:

CLI

oxlint --deny jsx-a11y/media-has-caption --jsx-a11y-plugin

Config (.oxlintrc.json)

  "plugins": ["jsx-a11y"],
