Laravel Auto Cache Clear

A Laravel package that automatically clears cache for Eloquent models using PHP attributes. Define cache-clearing behavior directly above your model with the #[ClearCacheWhen] attribute, and let the package handle the rest.

Features

• Attribute-Based Configuration: Use the #[ClearCacheWhen] attribute to define when cache should be cleared for a model.
• Automatic Cache Clearing: Automatically clears cache when specified model events occur.
• Dynamic Cache Keys: Define custom cache keys using placeholders like {model} and {id}.
• Static Cache Keys: Clear static cache keys (e.g., "users") when model events occur.
• Flexible and Extensible: Works with any Eloquent model.

Installation

1. Install the Package

composer require zidbih/laravel-auto-cache-clear

Usage

1. Add the #[ClearCacheWhen] Attribute to Your Model

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Zidbih\LaravelAutoCacheClear\Attributes\ClearCacheWhen;
use Zidbih\LaravelAutoCacheClear\Traits\AutoClearsCache;

#[ClearCacheWhen(['created', 'updated', 'deleted'], cacheKey: 'user:{id}:details', staticKeys: ['users'])]
class User extends Model
{
    use AutoClearsCache;
}

Attribute Parameters

• events: Model events that should trigger cache clearing (e.g., ['created', 'updated', 'deleted','restored']).
• cacheKey: Cache key pattern (default: {model}:{id}). You can use placeholders like {model} and {id}.
• staticKeys: An array of static cache keys to clear (e.g., ['users','posts']).

2. Use the AutoClearsCache Trait

use Zidbih\LaravelAutoCacheClear\Traits\AutoClearsCache;

class User extends Model
{
    use AutoClearsCache;
}

3. Cache Data in Your Application

use Illuminate\Support\Facades\Cache;

// Cache a list of users
$users = Cache::remember('users', 60, function () {
    return User::all();
});

// Cache a single user
$user = Cache::remember('user:1:details', 60, function () {
    return User::find(1);
});

When a user is created, updated, or deleted, the cache keys user:1:details and users will automatically be cleared.

Example Workflow

1. Define the Model

#[ClearCacheWhen(['created', 'updated', 'deleted'], staticKeys: ['users'])]
class User extends Model
{
    use AutoClearsCache;
}

2. Cache Data

$users = Cache::remember('users', 60*60*24, fn () => User::all());

3. Trigger Model Events

When a user is created, updated, or deleted, the following will be cleared:

• The static key: users
