Actually it is impossible to upgrade JSDOM because all objects are freezed. We should try to update it and not use it directly as an AST. We could modify properties in a kind of proxy.

jsdom is a pretty big package (a couple megabytes before transitive dependencies). Pinning it to a specific version prevents it from deduping with other versions of jsdom. For example, it currently cannot dedupe with the version required by jest.

Hey @neoziro just started poking around in h2x. It's awesome. You guys are creating such cool stuff.

Anyway, I'd love to start building a few h2x plugins but I'm also not familiar with how the tree traversals work.

here's the first plugin I'm thinking:

given an SVG like this:

<svg width="18" height="18" viewBox="0 0 60 60" xmlns:xlink="http://www.w3.org/1999/xlink" fill="rgb(255,255,255)">
  <defs>
    <path d="M16 16h28v4H16v-4zm-6 12h40v4H10v-4zm6 12h28v4H16v-4z" id="a"></path>
  </defs>
  <use fill="#FFF" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#a" fill-rule="evenodd"></use>
</svg>

I'd like to check to see if there is only 1 reference to a<use> remove the element from defs and inline it.

Hi, wondering if you know why this is failing?
