What is this?

This package is a small utility that checks if a node is interactive content according to HTML.

When should I use this?

This utility is super niche, if you’re here you probably know what you’re looking for!

Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install hast-util-interactive

In Deno with esm.sh:

import {interactive} from 'https://esm.sh/hast-util-interactive@3'

In browsers with esm.sh:

<script type="module">
  import {interactive} from 'https://esm.sh/hast-util-interactive@3?bundle'
</script>

Use

  properties: {},
  children: []
}) // => false

interactive({
  type: 'element',
  tagName: 'a',
  properties: {href: '#alpha'},
  children: []
}) // => true

interactive({

}) // => true

API

This package exports the identifier interactive. There is no default export.

node (Node, optional) — node to check

Whether node is an Element that is classified as interactive content (boolean).

The following elements are interactive:

a with href
audio or video with controls
img or object with useMap
input without hidden
any element with a tabIndex
the elements button, details, embed, iframe, keygen, label, select, and textarea

Types

This package is fully typed with TypeScript. It exports no additional types.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, hast-util-interactive@^3, compatible with Node.js 16.
