Vite plugin's global variables are `undefined` when using Deno
This turned out to be an issue with my Vite plugin config. It was working with a locally-linked package with bun (bun link <name>). But this isn't how Vite handles things with non-locally-linked packages. So, this is what resolved it for me: 
...
return {
  define: {
    'XINK_VITE_MODE': JSON.stringify(mode)
  },
  ssr: { noExternal: [ '@xinkjs/xink' ] // the plugin's package name
}
...
...
return {
  define: {
    'XINK_VITE_MODE': JSON.stringify(mode)
  },
  ssr: { noExternal: [ '@xinkjs/xink' ] // the plugin's package name
}
...

Getting error `Unrecognized algorithm name` on `crypto.subtle.importKey()`
Found out I need to base64 decode the key, before I convert it to an array buffer. But even then, undefined is thrown. Thoughts?

Getting error `Unrecognized algorithm name` on `crypto.subtle.importKey()`
I've now tried passing in an eliptical curve params object, instead of 'SHA-512'. This ends up throwing an undefined error. 
{
  name: 'ECDSA',
  namedCurve: 'P-521'
}
{
  name: 'ECDSA',
  namedCurve: 'P-521'
}
I also changed spki to pkcs8, as I realized this is for a private key.
