- Can I use PSL’s collections (Vec, Dict) to replace Laravel’s Collection class?
- Yes, but with caution. PSL’s collections are immutable and type-safe, offering stricter guarantees than Laravel’s mutable Collection. You’ll need to refactor existing methods like `push()` or alias them (e.g., `map` instead of `pluck`). Start with new services or DTOs to test compatibility before full migration.
- Will PSL work with Laravel 10 (PHP 8.2) or older versions?
- No, PSL requires PHP 8.4+. For Laravel 10 or older, consider a compatibility layer like `azjezz/psl-laravel` or focus on PSL’s async/networking components (e.g., HTTP clients) where it doesn’t depend on newer PHP features. Benchmark performance trade-offs carefully.
- How does PSL’s async/Promise system integrate with Laravel’s queue jobs?
- PSL’s Async and Promise APIs can wrap Laravel’s Bus/Jobs for I/O-bound tasks (e.g., API calls in background jobs). Use a custom dispatcher like `PslJobDispatcher` to bridge PSL’s fibers with Laravel’s queue system. Avoid mixing with existing Promise libraries (e.g., `spatie/promise`) to prevent conflicts.
- Is PSL’s type validation better than Laravel’s Validator for runtime checks?
- PSL’s Type system excels for strict, composable validation (e.g., shapes, unions) with zero reflection overhead, while Laravel’s Validator offers built-in rules (e.g., `email`, `date`). Use PSL for DTOs or API inputs where type safety is critical, and extend Laravel’s Validator with PSL rules for hybrid workflows.
- What’s the performance impact of using PSL’s immutable collections vs. Laravel’s?
- PSL’s immutability and type safety add runtime checks, which may slow bulk operations (e.g., `where()`, `pluck()`) compared to Laravel’s optimized Collections. Benchmark critical paths—PSL shines in correctness but trade-offs exist for high-throughput tasks. Consider hybrid usage for performance-sensitive code.
- How do I migrate from Laravel’s Collection to PSL without breaking existing code?
- Start incrementally: Replace `Collection` with PSL’s `Vec`/`Dict` in new classes, then alias methods (e.g., `pluck` → `map`) via a config file. Use a facade or trait to wrap PSL types for backward compatibility. Test thoroughly—immutability will catch bugs in mutable-dependent logic.
- Does PSL support Laravel’s async middleware or event listeners?
- PSL’s Async API works with Laravel’s async middleware (experimental in Laravel 11+) or event listeners via fibers. Wrap middleware logic in `Async
un()` or use PSL’s `Promise` for async responses. Ensure your server (e.g., Swoole, RoadRunner) supports fibers for full concurrency.
- Are there alternatives to PSL for type-safe collections in Laravel?
- Yes: `spatie/array` for lightweight collections, `symfony/collection` for mutable alternatives, or `league/collection` for immutable patterns. PSL stands out for its async-first design and deep integration with PHP 8.4+ features (e.g., enums, attributes), but may overkill for simple use cases.
- How does PSL handle mixed codebases with both Laravel and PSL types?
- Use a phased migration: Isolate PSL types in new modules (e.g., DTOs, services) and gradually replace Laravel utilities. For shared code, create adapters (e.g., `LaravelCollection::toPslVec()`). PSL’s strict typing may require IDE plugins (e.g., PHPStorm) to avoid false positives in mixed contexts.
- Can PSL’s networking tools (HTTP, TCP) replace Laravel’s HTTP client or Guzzle?
- PSL’s `Http` and `Socket` APIs offer type-safe, async alternatives to Guzzle or Laravel’s HTTP client, ideal for high-concurrency scenarios (e.g., scraping, microservices). They lack Guzzle’s middleware ecosystem but integrate seamlessly with PSL’s Async. Test error handling—PSL throws exceptions predictably, unlike Guzzle’s callbacks.
