Respond With

If we need to render a template to html render("template.slang") works nicely. A lot of times we want to respond with json, xml, text or something else. In those cases we use respond_with.

    respond_with do
      html render("index.slang")
      json pets.to_json
      xml render("index.xml.slang", layout: false)
      text "hello world"
    end
