That's the JavaScript/Node ecosystem in a nutshell. See the LeftPad fiasco and the mere existence of the IsOdd and IsEven packages for more poor judgement.

To be honest that’s because I didn’t flesh out JS counterpart yet. My plan was to have something similar to the Python version: https://codeberg.org/prettyid/python

Of course, if you like the idea but don’t want to add another dependency, you can copy-paste the three-liner as it is! (And I’m sure it’s not even copyrightable right now :-)

multiple dependencies,

Also requires two other packages to run its 3 lines of code.

"dependencies": { "@scure/base": "^1.1.7", "uuidv7": "^1.0.1" }

only if I can leftpad it first?

This is actually pretty good! And it seems to be compatible with my implementation (it’s also UUIDv7 and base32 alphabet is the same, but without mapping from OIL to 01).
