hast utility to create an element from a simple CSS selector.


What is this?

This package is a tiny utility that helps create elements.

When should I use this?

This utility is super niche. You probably want the more powerful hastscript or hast-util-from-selector


This package is ESM only. In Node.js (version 12.20+, 14.14+, 16.0+, or 18.0+), install with npm:

npm install hast-util-parse-selector

In Deno with esm.sh:

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

In browsers with esm.sh:

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


import {parseSelector} from 'hast-util-parse-selector'



{ type: 'element',
  tagName: 'div',
  properties: { id: 'bar', className: [ 'quux', 'baz', 'qux' ] },
  children: [] }


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

parseSelector([selector][, defaultTagName])

Create an element node from a simple CSS selector.




This package is fully typed with TypeScript. It exports no additional types. In TypeScript 4.2+, the type system can infer the tag name of literal selectors and knows that the return element has that name.


Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js 12.20+, 14.14+, 16.0+, and 18.0+. Our projects sometimes work with older versions, but this is not guaranteed.


Improper use of the selector or defaultTagName can open you up to a cross-site scripting (XSS) attack as the value of tagName, when resolving to script, injects a script element into the syntax tree.

Do not use user input in selector or use hast-util-santize.
