arubacao / asset-cdn by arubacao

Introduction

This package lets you push, sync, delete and serve assets to/from a CDN of your choice e.g. AWS Cloudfront.
It adds helper methods mix_cdn() and asset_cdn().

Simple Illustration

>>> env('USE_CDN')
=> true

$ php artisan asset-cdn:sync

// head.blade.php
<link rel="stylesheet" href="{{ mix_cdn('/css/app.css') }}">

<!-- Result -->
<link rel="stylesheet" href="https://cdn.mysite.com/css/app.css?id=081861342e950012abe3">

Installation

Install this package via composer:

$ composer require arubacao/asset-cdn

Also register the service provider:
Only required for Laravel <=5.4, for Laravel >=5.5 auto-discovery is enabled.

// config/app.php

'providers' => [
    // Other Service Providers
    \Arubacao\AssetCdn\AssetCdnServiceProvider::class,
],

Notes:

• arubacao/asset-cdn is functional and fully tested for Laravel 5.4 - 7.* on PHP 7.0, 7.1, 7.2, 7.3

Configuration

1. Configure Filesystem

Only required if you plan to manage your assets via the provided commands: asset-cdn:push, asset-cdn:sync, asset-cdn:empty

arubacao/asset-cdn utilizes Laravel's Filesystem to push, sync, delete assets to/from the CDN of your choice. Therefore, you have to configure and define a filesystem specific for CDN purposes. Please follow the official documentation.

If you plan to use AWS S3/Cloudfront you can use this configuration:

// config/filesystem.php

'asset-cdn' => [
    'driver' => 's3',
    'key' => env('AWS_ACCESS_KEY_ID'),
    'secret' => env('AWS_SECRET_ACCESS_KEY'),
    'region' => env('AWS_DEFAULT_REGION', 'us-east-1'),
    'bucket' => env('AWS_CDN_BUCKET'),
],

2. Publish Config File

$ php artisan vendor:publish --provider="Arubacao\AssetCdn\AssetCdnServiceProvider"

3. Edit cdn_url and filesystem.disk

// config/asset-cdn.php

[
    'cdn_url' => 'https://cdn.mysite.com',
    'filesystem' => [
        'disk' => 'asset-cdn',
    ],
]

4. Edit files in config/asset-cdn.php

Only required if you plan to manage your assets via the provided commands: asset-cdn:push, asset-cdn:sync, asset-cdn:empty

files always assumes a relative path from the public directoy

• ignoreDotFiles
  Excludes "hidden" directories and files (starting with a dot).

• ignoreVCS
  Ignore version control directories.

• include
  Any file that matches at least one include rule, will be included. No file is included by default.

  • paths
    Define paths that should be available on the CDN.
    The following example will match any file in any js or css path it can find in the public directory.

    'include' => [
        'paths' => [
            'js', 
            'css'
        ],
    ]
    
    /*
     * This config would try to find:
     * '/var/www/html/public/js'
     * '/var/www/html/public/css'
     * but also any other 'js' or 'css' path e.g.
     * '/var/www/html/public/vendor/js'
     * '/var/www/html/public/vendor/css'
     * You could explicitly exclude paths later
     */
    

  • files
    Define files that should be available on the CDN.
    The following example will match any file that starts with js/back.app.js in the public directory.

    'include' => [
        'files' => [
            'js/app.js',
        ],
    ],
    
    /*
     * This config would try to find:
     * '/var/www/html/public/js/app.js'
     * but also any other file that matches the path + filename e.g.
     * '/var/www/html/public/vendor/js/app.js'
     * You could explicitly exclude these files later
     */
    

  • extensions
    Define filetypes that should be available on the CDN.
    The following example will match any file of type *.css or *.js in the public directory.

    'include' => [
        'extensions' => [
            '*.js',
            '*.css',
        ],
    ],
    

  • patterns
    Define patterns for files that should be available on the CDN.
    The following example will match any file that starts with letters a or b in the public directory.

    /*
     * Patterns can be globs, strings, or regexes
     */
    
    'include' => [
        'patterns' => [
            '/^[a-b]/i', //  starting with letters a-b
        ],
    ],
    

• exclude
  Any file that matches at least one exclude rule, will be excluded. Files that are excluded will never be included, even if they have been explicitly included. Rules are identical as described above.

5. Set Additional Configurations for Uploaded Files

filesystem.options are passed directly to the Filesystem which eventually calls the underlying Storage driver e.g. S3.
Please refer to the corresponding storage driver documentation for available configuration options.
The following example is recommended for AWS S3.

// config/asset-cdn.php

[
    'filesystem' => [
        'disk' => 'asset-cdn',
        'options' => [
            'ACL' => 'public-read', // File is available to the public, independent of the S3 Bucket policy 
            'CacheControl' => 'max-age=31536000, public', // Sets HTTP Header 'cache-control'. The client should cache the file for max 1 year 
        ],
    ],
]

6. Set Environment Variable USE_CDN

# .env

USE_CDN=true # Enables asset-cdn
USE_CDN=false # Disables asset-cdn (default)

Usage

Commands

Recommended
Sync assets that have been defined in the config to the CDN. Only pushes changes/new assets. Deletes locally removed files on CDN.
