rehype plugin to remove comments.


What is this?

This package is a plugin that removes comments. By default it keeps conditional comments, optionally it removes them too.

When should I use this?

You can use this plugin when you want to improve the transfer size of HTML documents.


This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install rehype-remove-comments

In Deno with esm.sh:

import rehypeRemoveComments from 'https://esm.sh/rehype-remove-comments@5'

In browsers with esm.sh:

<script type="module">
  import rehypeRemoveComments from 'https://esm.sh/rehype-remove-comments@5?bundle'


On the API:

import {read} from 'to-vfile'
import {unified} from 'unified'
import rehypeParse from 'rehype-parse'
import rehypeStringify from 'rehype-stringify'
import rehypeRemoveComments from 'rehype-remove-comments'


async function main() {
  const file = await unified()
    .process(await read('index.html'))


On the CLI:

rehype input.html --use rehype-remove-comments --output output.html

On the CLI in a config file (here a package.json):

 "rehype": {
   "plugins": [
+    "rehype-remove-comments",


This package exports no identifiers. The default export is rehypeRemoveComments.

unified().use(rehypeRemoveComments[, options])

Remove comments.


Configuration (optional).


Whether to remove conditional comments too (boolean, default: false). The default behavior is to keep conditional comments. Conditional comments are a legacy feature that was specific to Internet Explorer. They were no longer used in IE 10.

HTML is handled according to WHATWG HTML (the living standard), which is also followed by browsers such as Chrome and Firefox.

Syntax tree

The syntax tree format used is hast.


This package is fully typed with TypeScript.


Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js 12.20+, 14.14+, and 16.0+. Our projects sometimes work with older versions, but this is not guaranteed.


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