What is this?

This package is a plugin that can remove certain attributes entirely or
replace their values with shorter equivalents.

When should I use this?

import {unified} from 'unified'

const file = await unified()
.use(rehypeParse)
.use(rehypeMinifyEnumeratedAttribute)
.use(rehypeStringify)
.process(await read('index.html'))

console.log(String(file))
`

Syntax

HTML is parsed according to WHATWG HTML (the living standard), which is also
followed by all browsers.

Syntax tree

The syntax tree used is [hast][].

Types

This package is fully typed with [TypeScript][].

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,
rehype-minify-enumerated-attribute@^5,
compatible with Node.js 16.

Security

As rehype works on HTML and improper use of HTML can open you up to a
[cross-site scripting (XSS)][xss] attack, use of rehype can also be unsafe.
Use [rehype-sanitize][rehype-sanitize] to make the tree safe.
