go-nanoid VS uuid

Using jaevor/go-nanoid for those short IDs. With a ID length of 10 it'll take about ~17 years to have ~1% chance of collision.

With criterion benchmarking, nanoids of length 255 average about 101ns to generate, whereas in my Go implementation they take over 470ns. I know this is just benchmarking and only nanoseconds, but it's nice to have a comparison.

I use Google's UUID package a lot. But every time I refer to it in a new package, the language server picks up https://github.com/gofrs/uuid instead of https://github.com/google/uuid and then complains that the gofrs package isn't in go.mod. I assume because it's the first alphabetically (though this seems like a huge supply chain security loophole).

Just store one single UUID as a token in a client's cookie (use https://github.com/google/uuid for ex), and associate that to a user ID (or anything else relevant in your case), and an expiry date for example

Depends on your needs I think, I generally just use github.com/google/uuid like /u/wowsux mentioned it supports v1 through v5 of the UUID spec.

And we are also going to use google/uuid to generate random uuids.

If you are using "github.com/google/uuid", try the following codes

You can see the same naming dilemma in many Go library implementations, i.e., where a package is used to organize functions related to a single a type (https://github.com/google/uuid) vs organizing code of related functionality (https://github.com/golang/go/tree/master/src/math).

Type inference is not perfect yet (especially for functional options). Also not being able to add type parameters to methods is a bit annoying (can be worked around using package-level functions) but besides that generics fit quite nicely into the library. If type inference gets better then I think I can even remove the hard dependency on github.com/google/uuid and let users use custom types for ids.
