Caching Basics

Framework caches

php artisan route:cache
php artisan config:cache
php artisan view:cache

Clear with the corresponding clear commands when needed in deployments.

Values and queries

Cache::remember("post:{$id}", 600, fn () => Post::findOrFail($id));

• Choose TTLs based on freshness requirements
• Invalidate explicitly on writes when correctness matters

Patterns and Strategies

// Stable keys and scopes (e.g., tenant, locale)
Cache::remember("tenant:{$tenantId}:users:index:page:1", now()->addMinutes(5), function () {
    return User::with('team')->paginate(50);
});

// Tags (supported drivers) for grouped invalidation
Cache::tags(['users'])->remember('users.index.page.1', now()->addMinutes(5), fn () => ...);
Cache::tags(['users'])->flush();

// Locks to ensure exclusive expensive work
Cache::lock('reports:daily', 30)->block(5, function () {
    generateReports();
});

• Use stable, namespaced keys; include any scoping dimension
• Prefer remember() to prevent thundering herds
• Use cache tags (if supported) to invalidate related entries together
• Avoid caching highly dynamic or user-specific data without a plan
• Document invalidation triggers next to cached code

Laravel 13+

// Extend TTL without re-fetching/re-storing the value
Cache::touch('user_session:123', 3600);
Cache::touch('analytics_data', now()->addHours(6));

// Filesystem-backed "storage" cache driver (e.g., S3 as a K/V store)
// config/cache.php
'storage' => [
    'driver' => 'storage',
    'disk' => env('CACHE_STORAGE_DISK', 's3'),
    'path' => env('CACHE_STORAGE_PATH', 'framework/cache/data'),
],

• Security default: serializable_classes is false in config/cache.php; allow-list classes you cache as objects
• Default cache/Redis prefixes changed underscores → hyphens in 13.x; pin CACHE_PREFIX/REDIS_PREFIX explicitly to avoid cold caches on upgrade
