Is the createUniqueId-helper safe to use?
We are currently using the createUniqueId-helper on the client only and today one of our data entries was overwritten. We are relatively sure, that this was because its ID was generated a second time when we created a new data entry. Can id clashes happen? Ids are rather short, so I imagine that this is definitely a possibility.
Would it be better to switch to something like nanoid here, which can be configured to use a longer id?

I ran into an issue with it recently when implementing saving and loading data in my project. Since
createUniqueId basically is based on a counter that increases on each use, if you load data that has ids generated by createUniqueId they won't count towards that counter and thus cause clashes.
I would switch to nanoidthats what I thought. We should probably add this somewhere to the docs, as this can lead to data corruption when misused.
