plug_cloudflare

Inspired by mod_cloudflare, this Elixir plug parses Cloudflare's CF-Connecting-IP HTTP request header into Plug.Conn's remote_ip field.

Setup

To use this plug in your projects, edit your mix.exs file and add the project as a dependency:

defp deps do
  [
    { :plug_cloudflare, "~> 1.1.0" }
  ]
end

This plug should be one of the first ones in your pipeline. It is therefore recommended to put it in the endpoint instead of a pipeline.

defmodule MyApp.Endpoint do
  use Phoenix.Endpoint, otp_app: my_app

  plug Plug.Cloudflare

  # Other plugs omitted for clarity
  
end
