Assets

Introduction

The asset manager can be used via API or, more commonly, within views. To use the class outside of views you will need to include the \Anomaly\Streams\Platform\Asset\Asset class.

Assetic is being deprecated. This document will assume it is still available for now.{.important}

Laravel Mix

All addons are now generated pre-configured and ready to use Mix. The asset class as mentioned above will not act as a compiler in the future so it is wise to familiarize yourself with Mix.

Collections

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

Collections are always named such a way that it reflects the desired output name.{.note}

The basic idea is that you add individual assets like example.theme.awesome::scss/inputs.scss to collections like theme.css and output them all together.

{{ 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/*") }}

<style type="text/css">
    {{ asset_inline("theme.css") }}
    {{ asset_inline("build.css") }}
</style>

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

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

Looping Assets

There are also collections like scripts.js and styles.css that are standard in core to be looped over so that your field types and other systems can display assets without a fixed collection cache file. Since these assets might be different on every page.

<style type="text/css">
    {% for style in asset_inlines("styles.css") %}
    {{ style|raw }}
    {% endfor %}
</style>

<script type="text/javascript">
    {% for script in asset_inlines("scripts.js") %}
    {{ script|raw }}
    {% endfor %}
</script>

Filters

Filters are used to mutate the content of the assets or provide commands to the asset manager.

Filters can be applied to individual assets in a collection as well as the entire collection.{.tip}

{{ asset_add("collection.css", "theme::example.scss", ["min", "live"]) }}

$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. Uses an alternate comment syntax {* *} to prevent clashes with CSS selectors.
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

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

$asset = app(\Anomaly\Streams\Platform\Asset\Asset::class);

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

Automatic Filters

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

Assetic is being deprecated. These flags will be removed when Assetic is removed.{.important}

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.

{{ 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') }}

$asset = app(\Anomaly\Streams\Platform\Asset\Asset::class);

$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');

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.

Asset Hint Reference{.link}

"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

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 the path hint:

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

$asset = app(\Anomaly\Streams\Platform\Asset\Asset::class);

$asset->add('theme.js', 'foo::example/test.js');

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.{.info}

Required Assets

You can force named assets to be included by using the required filter if needed. This is helpful if a static collection includes the library that may be included dynamically 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",
    ]
) }}

Clearing Asset Cache

You can use the asset:clear command to clear the asset cache files.

php artisan asset:clear

Optionally you can define whether to clear only public or admin asset caches.

php artisan asset:clear public
