What is this?
This package is a small utility that checks if a node is an element that has a given property.
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-has-property
In Deno with esm.sh
:
import {hasProperty} from 'https://esm.sh/hast-util-has-property@3'
In browsers with esm.sh
:
<script type="module">
import {hasProperty} from 'https://esm.sh/hast-util-has-property@3?bundle'
</script>
Use
import {hasProperty} from 'hast-util-has-property'
hasProperty({type: 'text', value: 'alpha'}, 'bravo') // => false
hasProperty(
{
type: 'element',
tagName: 'div',
properties: {id: 'bravo'},
children: []
},
'className'
) // => false
hasProperty(
{
type: 'element',
tagName: 'div',
properties: {id: 'charlie'},
children: []

There is no default export.

property.

)name

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-has-property@^3
, compatible with Node.js 16.
Security
hast-util-has-property
does not change the syntax tree so there are no
openings for cross-site scripting (XSS) attacks.
