Async Laravel Package

Product Decisions This Supports

• Performance Optimization: Enables parallel processing of CPU-intensive tasks (e.g., batch data transformations, image/video processing, or ML inference) to reduce latency and improve scalability.
• Background Jobs: Offloads long-running tasks (e.g., report generation, API integrations) to background workers, freeing up synchronous request threads.
• Build vs. Buy: Avoids reinventing parallelism logic (e.g., custom pcntl wrappers or queue systems like Laravel Queues for non-I/O-bound tasks).
• Roadmap: Supports future-proofing for:
  • Microservices: Parallelize internal service calls (e.g., user profile enrichment).
  • Real-Time Systems: Process time-sensitive data (e.g., fraud detection, analytics pipelines).
  • Cost Efficiency: Reduces cloud compute costs by optimizing resource usage (e.g., fewer servers for batch jobs).

When to Consider This Package

Adopt when:

• Tasks are CPU-bound (not I/O-bound; use queues like Laravel Queues or Redis for I/O).
• You need low-latency parallelism (e.g., <100ms tasks) without external dependencies (e.g., RabbitMQ).
• Running on Linux servers (PCNTL is Unix-only; Windows users need alternatives like popen or queues).
• Your team lacks expertise in multiprocessing but needs a simple API.
• You’re using Laravel and want to integrate with existing job systems (e.g., wrap spatie/async in a custom job class).

Look elsewhere if:

• Tasks are I/O-bound (use Laravel Queues, Symfony Messenger, or Pulsar).
• You need cross-platform support (Windows/macOS; consider reactphp or swoole).
• You require distributed task orchestration (e.g., Kubernetes, AWS Batch).
• Your team prefers event-driven architectures (e.g., Kafka, NATS) over process-based parallelism.

How to Pitch It (Stakeholders)

For Executives: "This package lets us run CPU-heavy tasks in parallel—like crunching large datasets or processing videos—without adding servers. For example, if our ‘Generate Reports’ endpoint takes 5 seconds, we can cut that to 1 second by splitting the work across 5 processes. It’s like adding horsepower to our app without buying a bigger engine. Best for batch jobs, real-time data processing, or offloading work from user-facing requests."

For Engineers: *"Spatie/Async is a lightweight wrapper for PHP’s pcntl extension that lets you fire-and-forget CPU-bound tasks in parallel. Key benefits:

• Simple API: Async::run(fn() => heavyComputation())—no queues or workers to manage.
• Laravel-friendly: Works alongside Queues (e.g., use it for pre-processing before queuing).
• No external deps: Just install and use (but requires Linux).
• Use cases: Image resizing, data migrations, or any blocking task that can be split. Tradeoff: Not for I/O-bound work (use Queues instead). Windows? Not supported."*

For Developers: *"Need to speed up a slow script? Wrap it in Async::parallel() and let PHP handle the rest. Example:

$results = Async::parallel([
    fn() => processUserData($user1),
    fn() => processUserData($user2),
]);

• Pros: No setup, no queues, just parallelism.
• Cons: PCNTL-only (Linux), no retries or monitoring (add those yourself). Perfect for: One-off scripts, CLI tools, or Laravel commands."*
