## What is this?

This package exposes a list of known tag names to markdown.

## When should I use this?

This package is only useful if you want to build an alternative to micromark.

## Install

This package is [ESM only][esm].
In Node.js (version 16+), install with [npm][]:

```sh
npm install micromark-util-html-tag-name
```

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

```js
import {htmlBlockNames, htmlRawNames} from 'https://esm.sh/micromark-util-html-tag-name@1'
```

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

```html
<script type="module">
  import {htmlBlockNames, htmlRawNames} from 'https://esm.sh/micromark-util-html-tag-name@1?bundle'
</script>
```

## Use

```js
import {htmlBlockNames, htmlRawNames} from 'micromark-util-html-tag-name'

console.log(htmlBlockNames) // ['address', 'article', …]
console.log(htmlRawNames) // ['pre', 'script', …]
```

## API

This module exports the identifiers [`htmlBlockNames`][api-html-block-names]
and [`htmlRawNames`][api-html-raw-names].
There is no default export.

### `htmlBlockNames`

List of lowercase HTML “block” tag names (`Array<string>`).

The list, when parsing HTML (flow), results in more relaxed rules (condition
6\).
Because they are known blocks, the HTML-like syntax doesn’t have to be strictly
parsed.
For tag names not in this list, a more strict algorithm (condition 7) is used
to detect whether the HTML-like syntax is seen as HTML (flow) or not.

This is copied from:
<https://spec.commonmark.org/0.30/#html-blocks>.

> 👉 **Note**: `search` was added in `CommonMark@0.31`.

### `htmlRawNames`

List of lowercase HTML “raw” tag names (`Array<string>`).

The list, when parsing HTML (flow), results in HTML that can include lines
without exiting, until a closing tag also in this list is found (condition
1\).

This module is copied from:
<https://spec.commonmark.org/0.30/#html-blocks>.

> 👉 **Note**: `textarea` was added in `CommonMark@0.30`.

`micromark-util-html-tag-name@^2`, compatible with Node.js 16.
This package works with `micromark@^3`.
