it messes with `import.meta.url`

[jimmywarting]

when i tried to load https://jspm.dev/await-sync in deno it failed with

error: Uncaught (in worker "") Module not found "https://jspm.dev/worker.js".

i guess it's b/c jspm tries to flatten out all files to the root

it then tries to load
https://jspm.dev//npm:await-sync@1.0.0

which then have code that looks like:

  // Create the worker thread
  const url = new URL('./worker.js', import.meta.url);
  const worker = new Worker(url, { type: 'module' });

but this file is located at https://jspm.dev/npm:await-sync@1.0.0 so therefore it tries to load the worker.js from https://jspm.dev/worker.js which is wrong.

so i then tested this out in jspm.io prod and it keeps the folder structure so it isn't flatten out at the root.
https://ga.jspm.io/npm:await-sync@1.0.0/mod.js

this looks promesing. it has /mod.js which is a good sign.
but then it tries to load https://ga.jspm.io/npm:await-sync@1.0.0/worker.js which (you guess'ed it) returns 404 not found 😕

i guess it's b/c it only saves files on the cdn that it can find via traversing import statements?

---

either way i can't use await-sync via jspm in any way possible.

We don't currently support the new URL('./path.js', import.meta.url) pattern in JSPM with import.meta.url replacements, but we should.

Thanks for posting the issue, I will try to get to a fix within the next week or so at most.
