# document-outerhtml

Like [Element.outerHTML][], but for the whole [Document][].

This means it returns a string containing the `<html>.....</html>` with all the content between, plus the `<!DOCTYPE ....>` declaration (if present), and any comments and stray elements or text nodes.

## Install

npm install "git+https://code.treora.com/gerben/document-outerhtml#latest"

or

npm install document-outerhtml@latest

..or equivalent

## Usage

import documentOuterHTML from 'document-outerhtml'

const html = documentOuterHTML(document)

## Licence

[CC0](https://creativecommons.org/publicdomain/zero/1.0/); do whatever you want with this code.

## See also

- [XMLSerializer.serializeToString][]; does nearly the same thing, except it creates XML.
