## What is this?

[`micromark-extension-gfm`][micromark-extension-gfm].

## Install

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

```sh
npm install micromark-util-combine-extensions
```

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

```js
import {combineExtensions} from 'https://esm.sh/micromark-util-combine-extensions@1'
```

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

```html
<script type="module">
  import {combineExtensions} from 'https://esm.sh/micromark-util-combine-extensions@1?bundle'
</script>
```

## Use

```js
import {gfmAutolinkLiteral} from 'micromark-extension-gfm-autolink-literal'
import {gfmStrikethrough} from 'micromark-extension-gfm-strikethrough'
import {gfmTable} from 'micromark-extension-gfm-table'
import {gfmTaskListItem} from 'micromark-extension-gfm-task-list-item'
import {combineExtensions} from 'micromark-util-combine-extensions'

const gfm = combineExtensions([gfmAutolinkLiteral, gfmStrikethrough(), gfmTable, gfmTaskListItem])

## 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,
`micromark-util-combine-extensions@2`, compatible with Node.js 16.
This package works with `micromark@3`.

## Security

This package is safe.
See [`security.md`][securitymd] in [`micromark/.github`][health] for how to
submit a security report.
