Asset

The \Anomaly\Streams\Platform\Asset\Asset class built over the Assetic framework by Kris Wallsmith provides a fluent API for managing collections of assets.

It can be used both in the API:

app(\Anomaly\Streams\Platform\Asset\Asset::class)
    ->add('theme.css', 'theme::example/text.less')
    ->add('theme.css', 'theme::example/foo.less')
    ->path(); // Returns the path of the concatenated theme.css file.

And also in Twig:

{{ asset_add("theme.css", "theme::less/fonts/fonts.less") }}
{{ asset_add("theme.css", "theme::less/theme/theme.less") }}
{{ asset_add("build.css", "theme::scss/theme/theme.scss") }}

{{ asset_add("theme.js", "theme::js/libraries/jquery.min.js") }}
{{ asset_add("theme.js", "theme::js/libraries/tether.min.js") }}
{{ asset_add("theme.js", "theme::js/libraries/bootstrap.min.js") }}
{{ asset_add("theme.js", "theme::js/libraries/prism.min.js") }}
{{ asset_add("theme.js", "theme::js/libraries/mark.min.js") }}
{{ asset_add("theme.js", "theme::js/theme/*") }}

{{ asset_style("theme.css", ["min"]) }}
{{ asset_style("build.css", ["live"]) }}

{% for style in asset_styles("styles.css") %}
    {{ style|raw }}
{% endfor %}

{{ asset_script("theme.js") }}

Introduction

This section will introduce you to the Asset class and and how to use it.

Assets

An asset is a file with filterable content that can be loaded and dumped.

Collections

Collections are used to organize the assets you are working with. Assets in a collection can be combined or used individually.

**Note:** Collections are _always_ named such that it reflects the desired output name.

$asset->add("collection.css", "theme::example.scss");
$asset->add("collection.js", "theme::example.js");

Filters

Filters are used to mutate the content of the assets.

**Note:** Filters can be applied to individual assets in a collection as well as the entire collection.

$asset->add("collection.css", "theme::example.scss", ["min", "live"]);

Available Filters

min: minifies content
less: parses LESS into CSS
styl: parses STYL into CSS
scss: parses SCSS into CSS
parse: parses content with Twig
coffee: compiles CoffeeScript into Javascript
embed: embeds image data in your stylesheets
live: refreshes content when LIVE_ASSETS is enabled
version: appends an automated version ID to the published path

Example

$asset->path('theme.css', ['version']);

Twig

{{ asset_style('theme.css', ['version']) }}

Automatic Filters

scss, less, styl, and coffee filters are are applied automatically to matching files.

You may wish to use files that use an alternate syntax like LESS for CSS or Coffee for Javascript. In most cases you do not need to manually add filters to compile these assets to relevant syntax for output. Simply add them along with your other assets.

Example

$asset
    ->add('theme.css', 'example::styles/example.css')
    ->add('theme.css', 'example::styles/example.less')
    ->add('theme.css', 'example::styles/example.scss')
    ->add('theme.css', 'example::styles/example.styl');

Twig

{{ asset_add('theme.css', 'example::styles/example.css') }}
{{ asset_add('theme.css', 'example::styles/example.less') }}
{{ asset_add('theme.css', 'example::styles/example.scss') }}
{{ asset_add('theme.css', 'example::styles/example.styl') }}

Path Hints

To avoid having to use full paths to your assets there are a number of path hints available. Hints are a namespace that prefixes the asset path.

"theme::js/initialize.js" // path-to-your-active-theme/resources/js/initialize.js

"anomaly.module.products::js/initialize.js" // path-to-products-module/resources/js/initialize.js

Available Path Hints

All paths are relative to your application's base path.

public: public/
node: node_modules/
asset: public/app/{app_reference}/
resources: resources/{app_reference}/
storage: storage/streams/{app_reference}/
download: public/app/{app_reference}/assets/downloads/
streams: vendor/anomaly/streams-platform/resources/
module: {active_module_path}/resources/
theme: {active_theme_path}/resources/
bower: bin/bower_components/

Addons also have path hints associated to them:

vendor.module.example: {addon_path}/resources/

Registering Path Hints

Registering path hints is easy. Just inject the \Anomaly\Streams\Platform\Asset\Asset class into your service provider or function and use the addPath method:

$asset->addPath("foo", base_path("example/path"));

Now you can use that path:

{{ asset_add('foo::example/test.js') }}

Configuration

Configuration can be found in the Streams Platform under config/resources/assets.php. You can publish the Streams Platform with php artisan streams:publish to override configuration or use .env variables to control them as available.

Configuring additional path hints

You can configure additional path hints for the asset service with the streams::assets.paths configuration value:

'paths' => [
    'example' => 'some/local/path',
    's3'      => 'https://region.amazonaws.com/bucket'
]

You can now use these hints just like all the others:

{{ asset_add('theme.js', 'example::example/test.js') }}

Configuring additional output hints

Output hints help the system interpret the correct output file extension for an asset. For example the hint for .less is .css:

'hints' => [
    'css' => [
        'less',
        'scss',
        'sass',
        'styl',
    ],
    'js'  => [
        'coffee',
    ],
]

Configuring compilers

By default Pyro leverages PHP compilers. You can opt into other compilers if you like:

'filters' => [
    'less' => env('LESS_COMPILER', 'php'),
    'sass' => env('SASS_COMPILER', 'php'),
]

Forcing asset compiling

You can force assets with the live filter to compile for every page load by defining the LIVE_ASSETS flag. This is helpful during development to control assets that change often:

'live' => env('LIVE_ASSETS', false)

Use true to compile all live assets. Use admin to compile all live admin assets. Use public to compile all live public assets.

Named Assets

Sometimes it's necessary to include assets in your addon that may be duplicated by other addons that share the library or script. You can name your assets to prevent further loading of the same assets elsewhere with the as:* filter. Named assets are unique across all collections.

{{ asset_add("styles.css", "anomaly.field_type.select::scss/choices.scss", ["as:jshjohnson/Choices.css"]) }}
{{ asset_add("scripts.js", "anomaly.field_type.select::js/choices.min.js", ["as:jshjohnson/Choices.js"]) }}

The name provided is forced lowercase internally to normalize names.{.tip}

Required Assets

You can force named assets to be included by using the required filter if needed. This is helpful if a static collection includles the library that may be included dynaically later.

{{ asset_add(
    "build.css",
    "pyrocms.theme.accelerant::scss/theme/theme.scss",
    [
        "required",
        "as:t4t5/sweetalert.css",
        "as:jshjohnson/Choices.css",
        "as:rstacruz/nprogress.css",
    ]
) }}

Basic Usage

Inject the Anomaly\Streams\Platform\Asset\Asset class into your own class or method to get started. You can also use the Streams Plugin to interact with the asset class.
