module Rack::Mime

Constants

MIME_TYPES

List of most common mime-types, selected various sources according to their usefulness in a webserving scope for Ruby users.

To amend this list with your local mime.types list you can use:

require 'webrick/httputils'
list = WEBrick::HTTPUtils.load_mime_types('/etc/mime.types')
Rack::Mime::MIME_TYPES.merge!(list)

To add the list mongrel provides, use:

require 'mongrel/handlers'
Rack::Mime::MIME_TYPES.merge!(Mongrel::DirHandler::MIME_TYPES)

Public Class Methods

mime_type(ext, fallback='application/octet-stream') click to toggle source

File.extname(file) returns.

fallback may be any object

Also see the documentation for MIME_TYPES

Usage:

Rack::Mime.mime_type('.foo')

This is a shortcut for:

Rack::Mime::MIME_TYPES.fetch('.foo', 'application/octet-stream')
# File lib/rack/mime.rb, line 16
def mime_type(ext, fallback='application/octet-stream')
  MIME_TYPES.fetch(ext.to_s.downcase, fallback)
end
