Install a Go UUID package

Go projects commonly use a UUID package such as github.com/google/uuid for generation and parsing.

Install Go UUID package
go get github.com/google/uuid

Generate and parse UUIDs in Go

Use uuid.NewString() for a string value and uuid.Parse() when validating external strings.

Generate and parse UUIDs in Go
package main

import (
    "fmt"
    "github.com/google/uuid"
)

func main() {
    id := uuid.NewString()
    parsed, err := uuid.Parse(id)
    fmt.Println(parsed, err)
}

Common Go UUID mistakes

Handle parse errors instead of assuming incoming strings are valid. Prefer a UUID package over a hand-written random string function.
