duplicate of #7 .

I will try and look at this later in the week. I am actually a little surprised it doesn't "just work"!

I just tested this (from the example):

$ udd import_map.json
import_map.json
[1/1] Update successful: https://deno.land/std@0.124.0/fmt/ -> 0.125.0
Successfully updated:
https://deno.land/std@0.124.0/fmt/ 0.124.0 -> 0.125.0

What further is needed?

(This behavior ought to be tested in CI... and documented in the README.)

I just tried this and for me it seems to just look up the first dependency. Can you confirm that it works with multiple? I've got some clearly outdated ones in my import map:

{
  "imports": {
    "$fresh/": "https://deno.land/x/fresh@1.0.0/",
    "preact": "https://esm.sh/preact@10.8.1",

  }
}

Warning deno task is unstable and may drastically change in the future
Task udd deno run -A --unstable https://deno.land/x/udd@0.5.0/main.ts import_map.json

Already latest version:

--> it may just be an issue around updating alpha releases tho.

@boredland I think the actual error there is that esm.sh urls are not being read correctly/at all !
