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 plug_cloudflare in your projects, edit your mix.exs file and add plug_cloudflare as a dependency:

defp deps do
  [
    {:plug_cloudflare, ">= 1.2.0"}
  ]
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

This project uses the C4.1 process for all code changes.
