Nanoid port for Elixir

Elixir port of NanoID (https://github.com/ai/nanoid), a tiny, secure URL-friendly unique string ID generator.

Safe. It uses cryptographically strong random APIs and guarantees a proper distribution of symbols.

Compact. It uses a larger alphabet than UUID (A-Za-z0-9_~) and has a similar number of unique IDs in just 21 symbols instead of 36.

Installation

The package can be installed as Hex package:

1. Add nanoid to your list of dependencies in mix.exs:

  def deps do
    [{:nanoid, "~> 1.0.0"}]
  end

1. Run mix deps.get to fetch the package from hex
