Asset management for Laravel 5

PHP

laravel-assets

Simple, flexible asset management for Laravel 5 - 8. Combine and minify your CSS and JS files to make your website faster.

Installation

Add the dependency to composer.json:

composer require fisharebest/laravel-assets

Starting with Laravel 5.5, packages are discovered automatically. For earlier versions, you must add the service provider and facade to config/app.php.

return [
    'providers' => [
        Fisharebest\LaravelAssets\AssetsServiceProvider::class,
    ],
    'aliases' => [
        'Assets' => Fisharebest\LaravelAssets\AssetsFacade::class,
    ],
]

Create a configuration file, config/assets.php, containing default values. Edit the settings in this file to match your project’s directory structure.

$ php artisan vendor:publish --provider="Fisharebest\LaravelAssets\AssetsServiceProvider"

Step 1. How to add assets

You would usually add assets in each of your templates (layouts, views, partials, etc.) that requires them.

<!-- resources/views/layouts/master.blade.php -->
<?php Assets::add(['jquery', 'bootstrap', 'global.js', 'style.css', 'analytics.js']) ?>
<!-- the rest of your view ... -->

<!-- resources/views/pages/list.blade.php -->
<?php Assets::add('list.js') ?>
<!-- the rest of your view ... -->

Of course, you could also add assets anywhere you choose; controllers, helpers, etc.

As well as individual files, you can add named collections of files.
These are defined in config/assets.php.

Where you have dependencies, you should list the files in the order they should be loaded.
For example, if list.js depends on jQuery, you would specify jQuery before list.js.

<!-- resources/views/pages/list.blade.php -->
<?php Assets::add(['jquery', 'list.js']) ?>
<!-- the rest of your view ... -->

Duplicates are ignored, so you can add jQuery to each view that uses it and it will
only be rendered once.

Step 2. How to render links to assets

It is conventional to render CSS assets in the <head> element, and JS assets at the
end of the <body> element.

<!-- resources/views/layouts/master.blade.php -->
<html>
    <head>
        {!! Assets::css() !!}
    </head>
    <body>
        ...
        {!! Assets::js() !!}
    </body>
</html>

But what if…

What if my assets don’t have a `.js` or `.css` extension?

Specify the type as a parameter when adding the assets. For example,

Assets::add('http://example.com/script?parameter', 'js')

What if I want to divide my assets into separate groups?

Specify the group as a parameter when adding and rendering assets.

<!-- resources/views/layouts/master.blade.php -->
<?php Assets::add('jquery.js') ?>
<?php Assets::add('ie8.js', null, 'ie8') ?>
<?php Assets::add('analytics.js', null, 'head-script') ?>
<html>
    <head>
        ...
        <!--[if lte IE 8]>{!! Assets::js('ie8') !!}<![endif]-->
        {!! Assets::js('head-script') !!}
    </head>
    <body>
        ...
        {!! Assets::js() !!}
    </body>
</html>

What if I want to add additional attributes to the style/script?

Specify a list of attributes as an argument to the render functions.

{!! Assets::css('print', ['media' => 'print']) !!}
{!! Assets::js('analytics', ['async']) !!}

What if I my asset files are tiny?

There’s a configuration option inline_threshold. Any asset file
smaller than this number of bytes will be rendered inline, thus saving
an HTTP request.

What if I want to change the configuration at runtime?

Configuration can be changed at any time. It only takes effect when
the assets are rendered.

Assets::setGzipStatic(6);
Assets::css(); // will create compressed assets

What if I want to use my own minifier?

Write your own filter (implement Fisharebest\LaravelAssets\Filters\FilterInterface)
and specify it in the configuration file config/assets.php. Use one of the existing
filters as a template.

What if I want to use a CDN or a cookie-free domain?

Specify a URL in the destination_url setting which corresponds to the folder given
in destination.

// config/assets.php
return [
    'destination'     => 'min',                   // We create assets here
    'destination_url' => 'http://my-cdn.com/min', // Users read assets from here
]

What if I need to copy my pipelined assets to an external server?

Write your own notifier (implement Fisharebest\LaravelAssets\Notifiers\NotifierInterface)
and specify it in the configuration file config/assets.php. Use one of the existing
notifiers as a template.

You would most likely set the destination_url to your CDN server, and add a notifier
which copies the file from the destination folder to this server.

What if I cannot use file_get_contents() because of firewall/proxy issues?

Write your own loader (implement Fisharebest\LaravelAssets\Loaders\LoaderInterface)
and specify it in the configuration file config/assets.php. Use one of the existing
loaders as a template.

How do I delete old files after I update my assets or change my filters?

There is an artisan command for that.

php artisan assets:purge
