NAME

Mojolicious::Plugin::AssetPack - Compress and convert css, less, sass and javascript files

VERSION

0.07

SYNOPSIS

In your application:

use Mojolicious::Lite;

plugin 'AssetPack';

# define assets: $moniker => @real_assets
app->asset('app.js' => '/js/foo.js', '/js/bar.js');
app->asset('app.css' => '/css/foo.less', '/css/bar.scss', '/css/main.css');

# you can combine with assets from web
app->asset('bundle.js' => (
  'http://cdnjs.cloudflare.com/ajax/libs/es5-shim/2.3.0/es5-shim.js',
  'http://cdnjs.cloudflare.com/ajax/libs/es5-shim/2.3.0/es5-sham.js',
  'http://code.jquery.com/jquery-1.11.0.js',
  '/js/myapp.js',
));

app->start;

In your template:

%= asset 'app.js'
%= asset 'app.css'

Or if you need to add the tags manually:

% for my $asset (asset->get('app.js')) {
  %= javascript $asset
% }

See also "register".

DESCRIPTION

Production mode

This plugin will compress scss, less, css and javascript with the help of external applications on startup. The result will be one file with all the sources combined. This file is stored in "Packed directory".

The files in the packed directory will have a checksum added to the filename which will ensure broken browsers request a new version once the file is changed. Example:

<script src="/packed/app-ed6d968e39843a556dbe6dad8981e3e0.js">

This is done using "process".

Development mode

This plugin will expand the input files to multiple script or link tags which makes debugging and development easier.

This is done using "expand".

TIP! Make morbo watch your less/sass files as well:

$ morbo -w lib -w templates -w public/sass

Preprocessors

This library tries to find default preprocessors for less, scss, js and css.

NOTE! The preprocessors require optional dependencies to function properly. Check out "detect" in Mojolicious::Plugin::AssetPack::Preprocessors for more details.

You can also define your own preprocessors:

app->asset->preprocessors->add(js => sub {
  my($assetpack, $text, $file) = @_;
  $$text = "// yikes!\n" if 5 < rand 10;
});

ATTRIBUTES

minify

Set this to true if the assets should be minified.

preprocessors

Holds a Mojolicious::Plugin::AssetPack::Preprocessors object.

out_dir

Holds the path to the firectory where packed files can be written. It defaults to "mojo-assetpack" directory in temp unless a static directory is writeable.

rebuild

Deprecated.

METHODS

add

$self->add($moniker => @rel_files);

Used to define new assets aliases. This method is called when the asset() helper is called on the app.

expand

$bytestream = $self->expand($c, $moniker);

This method will return one tag for each asset defined by the "$moniker".

Will also run "less" or "sass" on the files to convert them to css, which the browser understand.

The returning bytestream will contain style or script tags.

get

@files = $self->get($moniker);

Returns a list of files which the moniker point to. The list will only contain one file if the $moniker is minified.

process

$self->process($moniker => @files);

This method use "process" in Mojolicious::Plugin::AssetPack::Preprocessors to convert and/or minify the sources pointed at by $moniker.

The result file will be stored in "Packed directory".

register

plugin 'AssetPack', {
  cleanup => $bool, # default is true
  minify => $bool, # compress assets
  no_autodetect => $bool, # disable preprocessor autodetection
};

Will register the compress helper. All arguments are optional.

"cleanup" will remove any old processed files. You want to disable this if you have other web sites that need to access an old version of the minified files.

"minify" will default to true if "mode" in Mojolicious is "production".
