hast utility to check if a node is inter-element whitespace.

Contents

What is this?

This package is a small utility that checks if a node is whitespace 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 14.14+ and 16.0+), install with npm:

npm install hast-util-whitespace

In Deno with esm.sh:

import {whitespace} from 'https://esm.sh/hast-util-whitespace@2'

In browsers with esm.sh:

<script type="module">
  import {whitespace} from 'https://esm.sh/hast-util-whitespace@2?bundle'
</script>

Use

import {whitespace} from 'hast-util-whitespace'

whitespace({
  type: 'element',
  tagName: 'div',
  children: []
}) // => false

whitespace({
  type: 'text',
  value: '\t  \n'
}) // => true

whitespace({
  type: 'text',
  value: '  text\f'
}) // => false

API

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

whitespace(thing)

Check if the given value is inter-element whitespace.

Parameters
  • thing (unknown, optional) — thing to check (typically Node or string)
Returns

Whether the value is inter-element whitespace (boolean): consisting of zero or more of space, tab (\t), line feed (\n), carriage return (\r), or form feed (\f). If a node is passed it must be a Text node, whose value field is checked.

Types

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

Compatibility

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

Security

hast-util-whitespace does not change the syntax tree so there are no openings for cross-site scripting (XSS) attacks.
