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
