Taking Goldcrest for a spin

In this section, we will use what we’ve built, and the features we’ve added to Goldcrest up to this point, to build an example web application. This application will support routes that respond with both HTML and JSON. We will also test out the new feature added to Goldcrest.View, which allows us to call a helper function inside an HTML template.

Let’s start by creating a new mix project and adding goldcrest to its mix dependencies:

mix.exs

$ mix new tasks_web --sup
..
$ cd tasks_web
defmodule TasksWeb.MixProject do
  # ..
  # Run "mix help deps" to learn about dependencies.
  defp deps do
    [
      {:goldcrest, path: "../goldcrest"}
    ]
  end
end

Running mix deps.get should resolve hex dependencies for the tasks_web app.

Now, let’s add a router module with a default 404 handler....
