This package is a small utility that checks if a node is an element that hasa given property.

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

This package isESM only.In Node.js (version 16+), install withnpm:

npm install hast-util-has-property

In Deno withesm.sh:

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

In browsers withesm.sh:

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

import{hasProperty}from'hast-util-has-property'hasProperty({type:'text',value:'alpha'},'bravo')// => falsehasProperty({type:'element',tagName:'div',properties:{id:'bravo'},children:[]},'className')// => falsehasProperty({type:'element',tagName:'div',properties:{id:'charlie'},children:[]},'id')// => true

This package exports the identifierhasProperty.There is no default export.

Check ifnodeis an element and has aname property.

• node (Node) — node to check (typicallyElement)

Whethernode is an element that has aname property (boolean).

This package is fully typed withTypeScript.It exports no additional types.

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

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

hast-util-has-property does not change the syntax tree so there are noopenings forcross-site scripting (XSS) attacks.
