## What is this?

This package is a small utility that checks if a node is phrasing 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][esm].
In Node.js (version 16+), install with [npm][]:

```sh
npm install hast-util-phrasing
```

In Deno with [`esm.sh`][esmsh]:

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

In browsers with [`esm.sh`][esmsh]:

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

## Use

```js
import {phrasing} from 'hast-util-phrasing'

// Given flow content:
phrasing({
  type: 'element',
  tagName: 'div',
  children: [{type: 'text', value: 'Alpha'}]
})
// => false

// Given a phrasing element:
phrasing({
  type: 'element',
  tagName: 'meta',
  properties: {itemProp: 'bravo'},
  children: []
})
// => true

// Given a non-phrasing element:
phrasing({
  type: 'element',
  tagName: 'meta',
  properties: {charSet: 'utf8'},
  children: []
})
// => false

// Given text:
phrasing({type: 'text', value: 'Delta'})
// => true
```

## API

This package exports the identifier [`phrasing`][api-phrasing].
There is no default export.

### `phrasing(value)`

Check if the given value is [*phrasing*][spec] content.

###### Parameters

*   `value` ([`Node`][node])
    — node to check

###### Returns

Whether `value` is phrasing content (`boolean`).

## 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-phrasing@^3`,
compatible with Node.js 16.

## Security

`hast-util-phrasing` does not change the syntax tree so there are no openings
for [cross-site scripting (XSS)][xss] attacks.
