This package is a plugin that removes elements with http-equiv
attributes.
These elements can set the character encoding and natural language
of the document, but there are shorter ways to do that.
You can use this plugin when you want to improve the transfer size of HTML
documents.
This package is [ESM only][esm].
In Node.js (version 16+), install with [npm][]:
``sh`
npm install rehype-remove-meta-http-equiv
In Deno with [esm.sh][esm-sh]:
`js`
import rehypeRemoveMetaHttpEquiv from 'https://esm.sh/rehype-remove-meta-http-equiv@4'
In browsers with [esm.sh][esm-sh]:
`html`
On the API:
`js
import rehypeParse from 'rehype-parse'
import rehypeRemoveMetaHttpEquiv from 'rehype-remove-meta-http-equiv'
import rehypeStringify from 'rehype-stringify'
import {read} from 'to-vfile'
import {unified} from 'unified'
const file = await unified()
.use(rehypeParse)
.use(rehypeRemoveMetaHttpEquiv)
.use(rehypeStringify)
.process(await read('index.html'))
console.log(String(file))
`
On the CLI:
`sh`
rehype input.html --use rehype-remove-meta-http-equiv --output output.html

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-remove-meta-http-equiv@^4,
compatible with Node.js 16.
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.
