📛 NAME

MojoX::MIME::Types — MIME Types for Mojolicious

🚀 Quick Reference

Use Case	Command	Description
Set MIME types handler in Mojolicious	$app->types(MojoX::MIME::Types->new)	Replace default types handler with complete MIME::Types
Set MIME types handler in Mojolicious::Lite	app->types(MojoX::MIME::Types->new)	Same for Lite applications
Get MIME type for a file extension	$types->type('foo')	Returns first type for extension
Set a MIME type mapping (ignored)	$types->type(foo => 'text/foo')	Provided for compatibility; actual storage ignored
Detect extensions from Accept header	$types->detect('application/json;q=9')	Returns list of extensions (does not handle wildcards)
Get MIME type from filename	$types->file_type('image.png')	Returns MIME type string (experimental)
Access underlying MIME::Types object	$app->types->mimeTypes	Get full MIME::Types object for advanced queries

📜 INHERITANCE

MojoX::MIME::Types is a Mojo::Base

📋 SYNOPSIS

use MojoX::MIME::Types;

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

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

📖 DESCRIPTION

[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.

🛠️ METHODS

🔧 Constructors

MojoX::MIME::Types->new(%options)

Create the 'type' handler for Mojolicious. When you do not specify your own MIME::Type object ($mime_type), it will be instantiated 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 — Ignored.

Example:

$app->types(MojoX::MIME::Types->new);

# 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);
$app->types($types);

⚙️ Attributes

$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!

$obj->mimeTypes()

Returns the internal mime types object.

🚀 Actions

$obj->content_type($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().

Example:

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

$obj->file_type($filename)

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.

🔍 DETAILS

❓ Why?

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;
   ...
   $self->types(MojoX::MIME::Types->new);
}

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);
$self->types($types);

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:

app->types(MojoX::MIME::Types->new);
my $types = app->types;

⚡ Differences with Mojolicious::Types

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

• 🔸 The tables maintained by MIME::Types are complete. So: there shouldn't be a need to add your own types, not via types(), not via type(). All attempts to add types are ignored; better remove them from your code.
• 🔸 This plugin understands the experimental flag x- in types and handles casing issues.
• 🔸 Updates to the internal hash via types() are simply ignored, because it is expensive to implement (and won't add something new).
• 🔸 The detect() is implemented in a compatible way, but does not understand wildcards ('*'). You should use MIME::Types::httpAcceptBest() or MIME::Types::httpAcceptSelect() to replace this broken function.
