README

• resizes and stores images such as thumbnails or the original
• resized images are stored in a dedicated 'cache' disk to separate from real data
• works by generating a URL to a resized file
• if that URL is viewed, it initially hits a route which generates and saves that resized image
• this uses the concept that real files will always be served before the routes are processed

Agent Instructions

This Laravel package provides image resizing and caching functionality. When working with this codebase:

Key Components

• ImageStyle.php: Main class that handles image processing and URL generation
• ImageStyleController.php: Controller that handles dynamic image generation requests
• ServiceProvider.php: Registers the package services and routes
• helpers.php: Contains the img() helper function for easy access
• Commands: Clean and purge commands for cache management

Helper Function Usage

Use the img() helper function to generate image style URLs:

// Basic usage
img($imagePath)->thumbnail()
img($imagePath)->resize(300, 200)

// In Eloquent models
public function thumbnailUrl(): Attribute
{
    return Attribute::make(
        get: fn () => img($this->image)->thumbnail()
    );
}

Configuration

• Configuration file: config/imagestyle.php
• Cache disk must be configured in config/filesystems.php
• Routes are automatically registered via the ServiceProvider

Image Processing Flow

1. Helper function generates URL pointing to cache location
2. If cached file doesn't exist, route intercepts request
3. Controller processes original image and saves to cache
4. Subsequent requests serve the cached file directly

Development Notes

• Uses Intervention Image v3 for image processing
• Requires properly configured cache disk and storage links
• Images are stored in /storage/app/cache and served from /cache URL

Uses Intervention Images

• https://image.intervention.io/v3/modifying/resizing

Sample Attribute

    public function thumbnailUrl(): Attribute
    {
        return Attribute::make(
            get: fn () => img($this->image)->thumbnail()
        );
    }

Setup

1. Setup Cache Disk

• create and link a new local disk
• edit /config/filesystem.php
• add a cache disk

    'disks' => [

        ...

        'cache' => [
            'driver' => 'local',
            'root' => storage_path('app/cache'),
            'url' => env('APP_URL') . '/cache',
            'visibility' => 'public',
            'throw' => false,
        ],
    ],

2. Add a Storage link entry

    'links' => [
        public_path('storage') => storage_path('app/public'),
        public_path('cache') => storage_path('app/cache'),
    ],

3. Run Storage Link

a storage:link

• now files in the /storage/app/cache folder are accessible from the /cache folder in the domain name
