Hey @ebisbe - thanks for the contribution! Since this pull request is introducing a new dependency, we need to discuss with the team. I will keep you posted with updates.

Hi @danielleadams,

I can add it as a PeerDependency, that should work right?
Also I wanted to add the new

$util.autoKsuid() : String
Returns a 128-bit randomly generated KSUID (K-Sortable Unique Identifier) base62 encoded as a String with a length of 27.

Maybe you can discuss both cases as it would add a newer dependency as well.

LGTM! Thanks for the contribution @ebisbe 🥳

[danielleadams]

@ebisbe running our test suite on this and the I can approve. Thanks for your patience here! (This might need to be rebased because we changed some packages names, but lets see if it works)

UPDATE: can confirm it needs a rebase.

[ebisbe]

@danielleadams I just saw your EDIT by chance ( edits don't trigger email notifications ). Do I need to do something for the rebase?

[danielleadams]

@ebisbe the PR needs to be rebased on dev.

[ebisbe]

@danielleadams done
