ExScim

SCIM 2.0 implementation for Elixir. Adapter-based and modular - bring your own storage, authentication, and resource mapping. Built on RFC 7643, RFC 7644, and RFC 6902.

Packages

Package	Description
`ex_scim`	Core SCIM logic, operations, filter/path parsers
`ex_scim_ecto`	Ecto storage adapter (PostgreSQL, MySQL, SQLite)
`ex_scim_phoenix`	Phoenix controllers, router, and plugs
`ex_scim_client`	HTTP client for consuming SCIM APIs

Installation

Add the packages you need to mix.exs:

{:ex_scim, "~> 0.2"},
{:ex_scim_ecto, "~> 0.2"},        # optional: Ecto storage
{:ex_scim_phoenix, "~> 0.2"},     # optional: Phoenix endpoints
{:ex_scim_client, "~> 0.2"}       # optional: HTTP client

Quick Start

Configure ExScim and mount the SCIM routes:

# config/config.exs
config :ex_scim,
  base_url: "https://your-domain.com",
  storage_strategy: ExScimEcto.StorageAdapter,
  storage_repo: MyApp.Repo,
  user_model: MyApp.Accounts.User,
  group_model: MyApp.Accounts.Group,
  auth_provider_adapter: MyApp.Scim.AuthProvider

# lib/my_app_web/router.ex
pipeline :scim_api do
  plug :accepts, ["json", "scim+json"]
  plug ExScimPhoenix.Plugs.ScimContentType
  plug ExScimPhoenix.Plugs.ScimAuth
end

scope "/scim/v2" do
  pipe_through :scim_api
  use ExScimPhoenix.Router
end

All SCIM endpoints are now available under /scim/v2.
