Constant Summary

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)

Class Method Details

.mime_type(ext, fallback = 'application/octet-stream') ⇒ Object

Returns String with mime type if found, otherwise use fallback. ext should be filename extension in the ‘.ext’ format that

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
