rehype plugin to remove type and language attributes on JavaScript scripts.


What is this?

This package is a plugin that removes type and/or language attributes on JavaScript scripts, as they are unneeded. This plugin does not touch other <script> elements (such as JavaScript modules or non-JavaScript scripts).

When should I use this?

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

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.
