Output UUID in Go as a short string

Question

Is there a built in way, or reasonably standard package that allows you to convert a standard UUID into a short string that would enable shorter URL\'s?

I.e. taking adva

Answer 1

As suggested here, If you want just a fairly random string to use as slug, better to not bother with UUID at all.

You can simply use go's native math/rand library to make random strings of desired length:

import (
"math/rand"
"encoding/hex"
)


b := make([]byte, 4) //equals 8 charachters
rand.Read(b) 
s := hex.EncodeToString(b)
