NAME

Mojolicious::Static - Serve static files

SYNOPSIS

  use Mojolicious::Static;

  my $static = Mojolicious::Static->new;
  push @{$static->classes}, 'MyApp::Controller::Foo';
  push @{$static->paths}, '/home/sri/public';

DESCRIPTION

Mojolicious::Static is a static file server with Range, If-Modified-Since and If-None-Match support, based on RFC 7232 and RFC 7233.

ATTRIBUTES

Mojolicious::Static implements the following attributes.

asset_dir

  my $dir = $static->asset_dir;
  $static = $static->asset_dir('assets');

Subdirectory used for all static assets, defaults to assets.

classes

  my $classes = $static->classes;
  $static     = $static->classes(['main']);

Classes to use for finding files in DATA sections with Mojo::Loader, first one has the highest precedence, defaults to main. Only files with exactly one extension will be used, like index.html. Note that for files to be detected, these classes need to have already been loaded and added before "warmup" is called, which usually happens automatically during application startup.

  # Add another class with static files in DATA section
  push @{$static->classes}, 'Mojolicious::Plugin::Fun';

  # Add another class with static files in DATA section and higher precedence
  unshift @{$static->classes}, 'Mojolicious::Plugin::MoreFun';

extra

  my $extra = $static->extra;
  $static   = $static->extra({'foo/bar.txt' => '/home/sri/myapp/bar.txt'});

Paths for extra files to be served from locations other than "paths", such as the images used by the built-in exception and not found pages. Note that extra files are only served if no better alternative could be found in "paths" and "classes".

  # Remove built-in favicon
  delete $static->extra->{'favicon.ico'};

paths

  my $paths = $static->paths;
  $static   = $static->paths(['/home/sri/public']);

Directories to serve static files from, first one has the highest precedence.

  # Add another "public" directory
  push @{$static->paths}, '/home/sri/public';

  # Add another "public" directory with higher precedence
  unshift @{$static->paths}, '/home/sri/themes/blue/public';

prefix

  my $prefix = $static->prefix;
  $static    = $static->prefix('/static');

Prefix to use for all static files, defaults to undef. This can be very useful for production deployments where the reverse proxy server should take over serving static files.

METHODS

Mojolicious::Static inherits all methods from Mojo::Base and implements the following new ones.

asset_path

  my $path = $static->asset_path('/app.js');

Get static asset path.

dispatch

  my $bool = $static->dispatch(Mojolicious::Controller->new);

Serve static file for Mojolicious::Controller object.

file

  my $asset = $static->file('images/logo.png');
  my $asset = $static->file('../lib/MyApp.pm');

Build Mojo::Asset::File or Mojo::Asset::Memory object for a file, relative to "paths" or from "classes", or return undef if it doesn't exist. Note that this method uses a relative path, but does not protect from traversing to parent directories.

  my $content = $static->file('foo/bar.html')->slurp;

file_path

  my $path = $static->file_path('/index.html');

Get static file path with "prefix" if it has been configured.

is_fresh

  my $bool = $static->is_fresh(Mojolicious::Controller->new, {etag => 'abc'});
  my $bool = $static->is_fresh(
    Mojolicious::Controller->new, {etag => 'W/"def"'});

Check freshness of request by comparing the If-None-Match and If-Modified-Since request headers to the ETag and Last-Modified response headers.

These options are currently available:

etag

  etag => 'abc'
  etag => 'W/"abc"'

Add ETag header before comparing.

last_modified

  last_modified => $epoch

Add Last-Modified header before comparing.

serve

  my $bool = $static->serve(Mojolicious::Controller->new, 'images/logo.png');
  my $bool = $static->serve(Mojolicious::Controller->new, '../lib/MyApp.pm');

Serve a specific file, relative to "paths" or from "classes". Note that this method uses a relative path, but does not protect from traversing to parent directories.

serve_asset

  $static->serve_asset(Mojolicious::Controller->new, Mojo::Asset::File->new);

Serve a Mojo::Asset::File or Mojo::Asset::Memory object with Range, If-Modified-Since and If-None-Match support.

warmup

  $static->warmup();

Prepare static files from "classes" and static assets for future use.
