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-script-type-javascript@^4
,
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. Userehype-sanitize
rehype-sanitize to make the tree safe.Contribute
