end
desc "description"
params do
requires :age, type: Integer, values: 18..65

optional :avatar, type: File
optional :avatar_url, type: String
exactly_one_of [:avatar, :avatar_url]
end
post do
...
end
end
end
end
defmodule Router.Homepage do
use Maru.Router
resources do
get do
%{ hello: :world }
end
mount Router.User
end
end
defmodule MyAPP.API do
use Maru.Router
plug Plug.Static, at: "/static", from: "/my/static/path/"
mount Router.Homepage
rescue_from Unauthorized, as: e do
IO.inspect e
status 401
"Unauthorized"
end
rescue_from :all do
status 500
"Server Error"
end
end
```
then add the `maru` to your `config/config.exs`
```elixir
config :maru, MyAPP.API,
port: 8880
```
