## What is this?

This package is a tiny utility that gets the textual content of a node.

## When should I use this?

This utility is useful when you have a node, say a heading, and want to get the
text inside it.

This package does not serialize markdown, that’s what
[`mdast-util-to-markdown`][mdast-util-to-markdown] does.

Similar packages, [`hast-util-to-string`][hast-util-to-string] and
[`hast-util-to-text`][hast-util-to-text], do the same but on [hast][].

## Install

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

```sh
npm install mdast-util-to-string
```

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

```js
import {toString} from 'https://esm.sh/mdast-util-to-string@4'
```

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

```html
<script type="module">
  import {toString} from 'https://esm.sh/mdast-util-to-string@4?bundle'
</script>
```

## Use

```js
import {fromMarkdown} from 'mdast-util-from-markdown'
import {toString} from 'mdast-util-to-string'

const tree = fromMarkdown('Some _emphasis_, **importance**, and `code`.')

console.log(toString(tree)) // => 'Some emphasis, importance, and code.'
```

## API

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

### `toString(value[, options])`

Get the text content of a node or list of nodes.

Prefers the node’s plain-text fields, otherwise serializes its children,
and if the given value is an array, serialize the nodes in it.

###### Parameters

*   `value` (`unknown`)
    — thing to serialize, typically [`Node`][node]
*   `options` ([`Options`][api-options], optional)
    — configuration

###### Returns

Serialized `value` (`string`).

### `Options`

Configuration (TypeScript type).

###### Fields

*   `includeImageAlt` (`boolean`, default: `true`)
    — whether to use `alt` for `image`s
*   `includeHtml` (`boolean`, default: `true`)
    — whether to use `value` of HTML

## Types

This package is fully typed with [TypeScript][].
It exports the additional type [`Options`][api-options].

## 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, `mdast-util-to-string@^4`,
compatible with Node.js 16.

## Security

Use of `mdast-util-to-string` does not involve **[hast][]**, user content, or
change the tree, so there are no openings for [cross-site scripting (XSS)][xss]
attacks.
