Framework Laravel Package
laravel/framework
Laravel is a modern PHP web application framework with expressive syntax and batteries-included tooling: fast routing, dependency injection, sessions/cache, migrations, queues, and real-time broadcasting—built to make development enjoyable for apps of any size.
Laravel is a modern PHP web application framework focused on expressive syntax and developer productivity. This repository contains the core framework (not the application starter kit); to build an app, see the main laravel/laravel project and the official documentation at laravel.com.
Key capabilities include:
- Fast routing with clean, maintainable route definitions
- A powerful service container for dependency injection
- Flexible cache & session backends
- Database-agnostic migrations and schema tools
- Built-in queues and event broadcasting for async and realtime apps
Frequently asked questions about Framework
- What is Laravel Framework and how does it differ from the Laravel application starter?
- Laravel Framework is the core PHP package that powers Laravel applications, providing routing, dependency injection, Eloquent ORM, and other foundational tools. The `laravel/laravel` package is a pre-configured starter kit that includes the framework plus additional scaffolding like authentication and testing. Use the framework for custom projects or libraries, and the starter for quick app development.
- Which Laravel version supports PHP 8.2+ and what are the key improvements?
- Laravel 10+ fully supports PHP 8.2+, with optimizations like **Carbon 3.0**, **attribute-based routing**, and **enhanced queue performance** (e.g., `#[Delay]`, `#[WithoutOverlapping]`). Key improvements include **faster routing**, **simplified event handling**, and **better type safety** via PHP 8.2’s new features like read-only properties and native array unpacking.
- How do I install Laravel Framework in an existing PHP project?
- Add Laravel via Composer: `composer require laravel/framework`. For a new project, use `composer create-project laravel/laravel`. Laravel’s **service container** and **facades** integrate seamlessly with existing codebases, but ensure your project meets Laravel’s **PHP 8.1+** and **Composer** requirements. Avoid conflicts by checking `composer.json` for version constraints.
- Can Laravel Framework be used for microservices or API-only applications?
- Yes, but consider **Lumen** for ultra-lightweight APIs. Laravel supports API-first development with **API Resources**, **Sanctum/Passport** for auth, and **route caching**. For microservices, use **Laravel’s service container** for modularity and **queue workers** for async processing. Avoid monolithic structures by leveraging **Laravel’s package system** for isolated components.
- What are the best practices for caching and sessions in Laravel?
- Laravel supports **Redis, Memcached, database, and file-based** caching. Use `config/cache.php` to configure drivers and `Cache::remember()` for efficient data storage. For sessions, prefer **Redis or database** for scalability. Always **clear cached views** (`php artisan view:clear`) and **optimize queue jobs** (`php artisan queue:work --sleep=3 --tries=3`) to avoid performance bottlenecks.
- How does Laravel handle database migrations and schema changes?
- Laravel’s **migrations** use a simple, version-controlled approach to schema changes. Run `php artisan migrate` to apply changes, and `php artisan migrate:status` to track them. For complex schemas, use **Eloquent model events** or **observers**. Always **back up databases** before migrations and test in staging first to avoid production downtime.
- Is Laravel Framework suitable for real-time applications like chat or live updates?
- Yes, Laravel supports real-time features via **Laravel Echo** (WebSocket client) and **Pusher/Ably** for broadcasting. Use **events** (`Event::dispatch()`) and **channels** (`Broadcast::channel()`) to push updates. For high traffic, **scale with Laravel Horizon** (queue monitoring) and **Redis** for pub/sub. Test with `php artisan queue:work` in production.
- What are the alternatives to Laravel Framework for PHP development?
- Alternatives include **Symfony** (modular, enterprise-focused), **Lumen** (lightweight APIs), **Slim PHP** (micro-framework), and **Yii2** (high-performance). Laravel stands out for its **batteries-included** approach, **Eloquent ORM**, and **developer experience**. Choose Symfony for granular control or Lumen for APIs, but Laravel offers the best balance for full-stack apps.
- How do I test Laravel Framework components in isolation?
- Use Laravel’s **PHPUnit** integration with `php artisan test`. Mock dependencies via **Laravel’s service container** or **facades** with `Facade::shouldReceive()`. Test migrations with `MigrateFreshDatabaseTests`, and API routes with `Http::fake()`. For unit testing, extract logic into **services** and use **dependency injection** to swap implementations.
- What are common production concerns when deploying Laravel applications?
- Key concerns include **queue workers** (`php artisan queue:work --daemon`), **caching** (Redis/Memcached), and **session storage** (database/Redis). Use **Laravel Forge/Envoyer** for deployments, **Horizon** for queue monitoring, and **Vapor** for serverless. Always **optimize Blade templates** (`php artisan view:clear`) and **disable debug mode** (`APP_DEBUG=false`) in production.
