Asset
@TODO remove Laravel links to preserve version integrity
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.
Collections are always named such that it reflects the desired output name.{.tip}
$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.
Filters can be applied to individual assets in a collection as well as the entire collection.{.notice}
$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
$asset->path('theme.css', ['version']);
{{ 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.
$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');
{{ 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
We list all the available path hints for assets in the reference section.{.link}
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",
]
) }}
