Mojolicious::Static(3)

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 <https://tools.ietf.org/html/rfc7232> and RFC 7233 <https://tools.ietf.org/html/rfc7233>.

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.
