npm install hast-util-embedded

<script type="module">
  import {embedded} from 'https://esm.sh/hast-util-embedded@3?bundle'

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, hast-util-embedded@^3, compatible with Node.js 16.

Security

hast-util-embedded does not change the syntax tree so there are no openings for cross-site scripting (XSS)xss attacks.
