Raddocs is a browser for JSON outputted by the rspec_api_documentation gem.

Gemfile

gem 'raddocs'

config/routes.rb

  mount Raddocs::App => "/docs"

Make sure RspecApiDocumentation is generating JSON:

spec/spec_helper.rb

RspecApiDocumentation.configure do |config|
  config.format = :json
end

• api_name - Name of the API on the example index page
• docs_dir - where the JSON output from rspec_api_documentation is located
• docs_mime_type - if you use the middleware, what mime type are you serving your docs as, must be a regex. eg: /text\/vnd.org.oestrich.raddocs\+plain/
• include_bootstrap - Boolean to disable including bootstrap if you are using your own css
• external_css - Array of css files to include, with a full URL to them
• url_prefix - Optional prefix to insert before URLs generated by Raddocs
• index_view - Optional configuration to change the view of index page to tabular format with navbar header by setting value as tabular. Requires latest rspec_api_documentation gem. Changes display link to Http method + Route Url. eg: GET /api/orders

Raddocs.configure do |config|
  config.docs_dir = "doc/api"
end

You can include extra css by the config option external_css or add a directory to the docs dir named styles. Every css file in the styles dir will be included as a link element on all pages.
