Elixir: Custom Plug Part 1 - [008]

We need to be able to detect which kind of user is accessing our site. Based on the slides in the 002 episode we have 3 kinds of audiences. We need to put this concept into code. When request comes in we need to develop the plug that will detect our audience for us.

Basic Plug

We'll begin with the basic plug in the lib/botiful create a file called agent_plug.ex with the following content

defmodule Botiful.AgentPlug do  import Plug.Conn    require IEx    def init(options), do: options    def call(conn, _opts) do    IEx.pry  endend

This is the most basic plug one can have we'll use this code to explore what is inside of the conn .
