file can be used to return a file and it's contents to the browser, or render the contents of the file inline to a web browser. Options for the method:

• path - first argument, required. The path to the file.
• content_type - defaults to the mime-type that corresponds to the file's extension.
• disposition - default "attachment" (downloads file), or "inline" (renders file in browser).
• filename - default nil. When overridden and paired with disposition: "attachment" this will download file with the provided filename.
• status - Int32 - the HTTP status code to return with.

Examples:

  get "/file" do
    file "spec/fixtures/lucky_logo.png"
  end
end

For a plain text file with no extension, have it downloaded with the file named "custom.html" and the content_type "text/html":

class Rendering::File::CustomContentType < Lucky::Action
  get "/foo" do
    file "spec/fixtures/plain_text",
      disposition: "attachment",
      filename: "custom.html",
      content_type: "text/html"
  end
end
