glanoid

Gleam port of nanoid.

Installation

gleam add glanoid

Usage

Default alphabet

Use the following to generate IDs with the default alphabet (A-Za-z0-9_-).

Generate the nanoid function with glanoid.make_generator(glanoid.default_alphabet).
Then call the function with the desired ID length as an argument.

import glanoid
import gleam/io

pub fn main() {
  let assert Ok(nanoid) = glanoid.make_generator(glanoid.default_alphabet)
  nanoid(18)
  |> io.debug() // "bppqBa-4eNFW_yPzib"
}

Custom alphabet

import glanoid
import gleam/io

pub fn main() {
  let assert Ok(nanoid) = glanoid.make_generator("lucy")
  nanoid(18)
  |> io.debug() // "lluucyuyulycyucucy"
}

Collision probability

You can use the ID collision probability calculator to check the safety of your ID size and alphabet.
