MojoX::MIME::Types - MIME Types for Mojolicious


   is a Mojo::Base


  use MojoX::MIME::Types;

  # set in Mojolicious as default
  app->types(MojoX::MIME::Types->new);   # ::Lite

  # basic interface translated into pure MIME::Types
  $types->type(foo => 'text/foo');
  say $types->type('foo');


[Added to MIME::Types 2.07] This module is a drop-in replacement for Mojolicious::Types, but with a more correct handling plus a complete list of types... a huge list of types.

Some methods ignore information they receive: those parameters are accepted for compatibility with the Mojolicious::Types interface, but should not contain useful information.

Read the "DETAILS" below, about how to connect this module into Mojolicious and the differences you get.




Create the 'type' handler for Mojolicious. When you do not specify your own MIME::Type object ($mime_type), it will be instantanted for you. You create one yourself when you would like to pass some parameter to the object constructor.

 -Option    --Default
  mime_types  <created internally>
  types       undef
mime_types => MIME::Types-object

Pass your own prepared MIME::Types object, when you need some instantiation parameters different from the defaults.

types => HASH




  # when you need to pass options to MIME::Types->new
  my $mt    = MIME::Types->new(%opts);
  my $types = MojoX::MIME::Types->new(mime_types => $mt);


$obj->mapping( [\%table] )

In Mojolicious::Types, this attribute exposes the internal administration of types, offering to change it with using a clean abstract interface. That interface mistake bites now we have more complex internals.

Avoid this method! The returned HASH is expensive to construct, changes passed via %table are ignored: MIME::Types is very complete!


Returns the internal mime types object.


$obj->content_type($controller, \%options)

Set a content type on the controller when not yet set. The %options contains ext or file specify an file extension or file name which is used to derive the content type. Added and marked EXPERIMENTAL in Mojo 7.94.

$obj->detect( $accept, [$prio] )

Returns a list of filename extensions. The $accept header in HTTP can contain multiple types, with a priority indication ('q' attributes). The returned list contains a list with extensions, the extensions related to the highest priority type first. The $prio-flag is ignored. See MIME::Types::httpAccept().

This detect() function is not the correct approach for the Accept header: the "Accept" may contain wildcards ('*') in types for globbing, which does not produce extensions. Better use MIME::Types::httpAcceptBest() or MIME::Types::httpAcceptSelect().


  my $exts = $types->detect('application/json;q=9');
  my $exts = $types->detect('text/html, application/json;q=9');

Return the mime type for a filename. Added and marked EXPERIMENTAL in Mojo 7.94.

$obj->type( $ext, [$type|\@types] )

Returns the first type name for an extension $ext, unless you specify type names.

When a single $type or an ARRAY of @types are specified, the $self object is returned. Nothing is done with the provided info.



The Mojolicious::Types module has only very little knowledge about what is really needed to treat types correctly, and only contains a tiny list of extensions. MIME::Types tries to follow the standards very closely and contains all types found in various lists on internet.

How to use with Mojolicious

Start your Mojo application like this:

  package MyApp;
  use Mojo::Base 'Mojolicious';

  sub startup {
     my $self = shift;

If you have special options for MIME::Types::new(), then create your own MIME::Types object first:

  my $mt    = MIME::Types->new(%opts);
  my $types = MojoX::MIME::Types->new(mime_types => $mt);

In any case, you can reach the smart MIME::Types object later as

  my $mt    = $app->types->mimeTypes;
  my $mime  = $mt->mimeTypeOf($filename);

How to use with Mojolicious::Lite

The use in Mojolicious::Lite applications is only slightly different from above:

  my $types = app->types;

Differences with Mojolicious::Types

There are a few major difference with Mojolicious::Types:
