EctoKsuid allows seamless usage of ksuids with :ecto in your application. To get a better idea of what ksuids are, and how they came to be I highly recommend reading A breif History of the UUID

[Ksuid] borrows core ideas from the ubiquitous UUID standard, adding time-based ordering and more friendly representation formats.

Additionally, EctoKsuid allows easy addition of a :prefix to the ksuid that are available at runtime. This generates developer friendly ids much like stripe's object prefixed ids in your elixir application.

Documentation can be found online on HexDocs.

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

   def deps do
     [
       # ...
       {:ecto_ksuid, "~> 0.3.0"}
     ]
   end

2. Install using mix.

   mix deps.get

EctoKsuid is just a custom Ecto.ParameterizedType and can be used in your application just like any other Ecto type.

1. Add columns to your database

   defmodule MyApp.Repo.Migrations.AddPublicIdToUsers do
     use Ecto.Migration
   
     def change do
       alter table(:users) do
         add :public_id, EctoKsuid.column()
       end
     end
   end

2. Add fields to your schema

   defmodule MyApp.User do
     use Ecto.Schema
   
     schema "users" do
       # ...
       field :public_id, EctoKsuid
     end
   end
