Responding with html.eex files

Now that we know how to use EEx to create templates using Elixir, it’s time to start responding with embedded Elixir with our HTTP server.

Let’s start by creating a new mix project:

$ mix new example_server_html_eex

In order to use Goldcrest with this new app, let’s start by adding goldcrest as a mix dependency in example_server_html_eex:

mix.exs

defmodule ExampleServerHtmlEex.MixProject do
  # ..
  defp deps do
    [
      {:goldcrest, "~> 0.0.1"}
    ]
  end
end

We can fetch the dependency by running $ mix deps.get, and once fetched, let’s add a Router module. This router will be very similar to the one we created in Chapter 5, with the only difference being the content type of the response. For this router, we will respond with the text/html content:

lib/example_server_html_eex/router.ex
