Caching dramatically improves performance by storing expensive computations or database queries. Laravel supports multiple cache drivers—Redis, Memcached, file, database. I use Cache::remember() to fetch or compute and cache values with expiration. Ca

Query scopes encapsulate common query constraints into reusable methods on models. Local scopes prefix methods with scope and accept a query builder plus additional parameters. I chain scopes fluently—Post::published()->featured()->get(). Global

Laravel notifications send messages across email, SMS, Slack, database, and more via a unified API. I create notification classes extending Notification with channel-specific methods—toMail(), toDatabase(), toSlack(). The via() method determines which

Rate limiting prevents API abuse by restricting request frequency per user or IP. Laravel's RateLimiter facade defines limits in RouteServiceProvider. I apply limiters via middleware—throttle:api for the default API limiter. Custom limiters use closur

Inertia.js bridges Laravel backends with Vue, React, or Svelte frontends without building a separate API. Server-side controllers return Inertia responses containing component names and props. The frontend renders those components with reactive framew

Seeders populate databases with test or initial data. I create seeder classes in database/seeders with a run() method. The DatabaseSeeder orchestrates other seeders. For large datasets, I use factories with factory()->count(100)->create() for pe

Livewire enables reactive, dynamic interfaces without writing JavaScript—components re-render automatically when properties change. I create Livewire components as PHP classes with public properties and methods. Properties bind to Blade views with wir

Laravel collections provide a fluent, powerful API for working with arrays. Every Eloquent query returns a collection, but I also create collections from arrays with collect(). Methods like map(), filter(), reduce(), groupBy(), and sortBy() transform

Policies organize authorization logic around models, keeping permission checks clean and reusable. Each policy method corresponds to an action—view, create, update, delete. I call policies via the Gate facade or authorize() helper in controllers. The

Database transactions ensure multiple database operations succeed or fail together, maintaining data consistency. I wrap related operations in DB::transaction() which automatically commits on success and rolls back on exceptions. For manual control, I

Laravel Sanctum provides lightweight API authentication for SPAs and mobile apps. For SPAs on the same domain, Sanctum uses Laravel's session cookies with CSRF protection. For mobile apps or third-party clients, it issues API tokens stored in a person

Events and listeners decouple application logic, making code modular and testable. When significant actions occur—user registered, order placed—I fire events. Multiple listeners can respond to one event without the event knowing about them. Events are
