Phoenix will by default server some files and directories from
priv/static. More specifically
robots.txt. If you need to add a new directory however simply creating it in
priv/static will not make Phoenix serve it. You need to explicitly add it.
Say your project is called
ChicagoElixir you will need to go to your endpoint configuration, typically in:
lib/chicago_elixir/web/endpoint.ex. There you will find the following configuration:
plug Plug.Static, at: "/", from: :chicago_elixir, gzip: false, only: ~w(css fonts images js favicon.ico robots.txt)
Simply add the new folder or file name to the list in
only and restart your Phoenix server.
