Node v21 - navigator object

[sadiqsalau]

Can't compile when using Node v21 because of the introduction of navigator object.

Can you provide more details? What fails specifically? Why do you think the navigator object is related?

Compiler fails with following error: TypeError: Cannot read properties of undefined (reading 'indexOf') 💥
Bcos of this code:

function(hooks) {
  if (typeof navigator != "object") return hooks;
  var ua = navigator.userAgent;
  if (ua.indexOf("DumpRenderTree") >= 0) return hooks;
  if (ua.indexOf("Chrome") >= 0) {
    function confirm(p) {
      return typeof window == "object" && window[p] && window[p].name == p;
    }
    if (confirm("Window") && confirm("HTMLElement")) return hooks;
  }
  hooks.getTag = getTagFallback;
}

Whereas navigator.userAgent is undefined 🥴

It's astonishing to me that Node.js thought it would be a good idea to add a global navigator object, but setting that aside: this is an issue with the standard code generated by dart2js, and should be filed against https://github.com/dart-lang/sdk. There's nothing we can do in Dart Sass to fix this.

Note that Node.js 21 is also not an LTS release, and thus may receive less support than an even-numbered release.
