Renders a [domhandler](https://github.com/fb55/domhandler) DOM node or an array of domhandler DOM nodes to a string.

```js

// OR

```

# API

## `render`

▸ **render**(`node`: Node \| Node[], `options?`: [_Options_](#Options)): _string_

Renders a DOM node or an array of DOM nodes to a string.

Can be thought of as the equivalent of the `outerHTML` of the passed node(s).

#### Parameters:

| Name      | Type                               | Default value | Description                    |
| :-------- | :--------------------------------- | :------------ | :----------------------------- |
| `node`    | Node \| Node[]                     | -             | Node to be rendered.           |
| `options` | [_DomSerializerOptions_](#Options) | {}            | Changes serialization behavior |

**Returns:** _string_

## Options

### `encodeEntities`

• `Optional` **decodeEntities**: _boolean | "utf8"_

Encode characters that are either reserved in HTML or XML.

If `xmlMode` is `true` or the value not `'utf8'`, characters outside of the utf8 range will be encoded as well.

**`default`** `decodeEntities`

---

### `decodeEntities`

• `Optional` **decodeEntities**: _boolean_

Option inherited from parsing; will be used as the default value for `encodeEntities`.

**`default`** true

---

### `emptyAttrs`

• `Optional` **emptyAttrs**: _boolean_

Print an empty attribute's value.

**`default`** xmlMode

**`example`** With <code>emptyAttrs: false</code>: <code><input checked></code>

**`example`** With <code>emptyAttrs: true</code>: <code><input checked=""></code>

---

### `selfClosingTags`

• `Optional` **selfClosingTags**: _boolean_

Print self-closing tags for tags without contents.

**`default`** xmlMode

**`example`** With <code>selfClosingTags: false</code>: <code><foo></foo></code>

**`example`** With <code>selfClosingTags: true</code>: <code><foo /></code>

---

### `xmlMode`

• `Optional` **xmlMode**: _boolean_ \| _"foreign"_

Treat the input as an XML document; enables the `emptyAttrs` and `selfClosingTags` options.

If the value is `"foreign"`, it will try to correct mixed-case attribute names.

**`default`** false
