module Roda::RodaPlugins::Public

  1. lib/roda/plugins/public.rb

The public plugin adds a r.public routing method to serve static files from a directory.

The public plugin recognizes the application's :root option, and defaults to using the public subfolder of the application's :root option. If the application's :root option is not set, it defaults to the public folder in the working directory. Additionally, if a relative path is provided as the :root option to the plugin, it will be considered relative to the application's :root option.

Examples:

# Use public folder as location of files
plugin :public

# Use /path/to/app/static as location of files
opts[:root] = '/path/to/app'
plugin :public, root: 'static'

# Assuming public is the location of files
r.route do
  # Make GET /images/foo.png look for public/images/foo.png 
  r.public

  # Make GET /static/images/foo.png look for public/images/foo.png
  r.on(:static) do
    r.public
  end
end
