Process Laravel Package

Technical Evaluation

Architecture Fit

• Seamless Laravel Integration: Symfony Process is a first-party Symfony component with deep Laravel compatibility (e.g., PSR-4 autoloading, Symfony’s dependency injection). It replaces manual shell_exec(), exec(), or proc_open() calls with a consistent, feature-rich API.
  • Example: Replace:

    exec('docker build --build-arg ARRAY=' . json_encode($config), $output, $return);
    

    with:

    $process = new Process(['docker', 'build'], [
        '--build-arg' => ['ARRAY=' . json_encode($config)],
    ]);
    $process->run();
    

• Event-Driven Extensibility: Integrates with Laravel’s event system (e.g., ProcessEvent::TERMINATED) and Symfony Messenger for async subprocesses.
• Cross-Cutting Concerns: Handles timeouts, signals (SIGTERM/SIGKILL), and I/O streams out-of-the-box, reducing boilerplate.

Integration Feasibility

• Zero Laravel-Specific Overhead: Works as a standalone PHP library (no Symfony Framework required). Compatible with:
  • Laravel 10+ (PHP 8.1+).
  • Legacy Laravel (v7.4.x/v8.0.x via Symfony Process v7.4/v8.0).
• Dependency Graph:

  graph TD
    A[Laravel App] -->|composer| B[symfony/process:^8.1]
    B --> C[php:^8.1]
    B --> D[symfony/polyfill:^1.26]
  

• Key Integration Points:
  • Service Providers: Register Process as a singleton or bind to interfaces (e.g., ProcessRunnerInterface).
  • Artisan Commands: Use Process for CLI-driven tasks (e.g., php artisan deploy:docker).
  • Queues/Jobs: Wrap Process in a ShouldQueue job for async execution.

Technical Risk

Key Questions

1. Use Case Specificity:
   • Are subprocesses synchronous (e.g., CLI tools) or asynchronous (e.g., long-running jobs)? If async, pair with Laravel Queues.
   • Do you need real-time I/O streaming (e.g., Process::mustRun()) or batch processing (e.g., Process::run())?
2. Environment Complexity:
   • Will subprocesses require nested/array environment variables (v8.1+ feature) or simple key-value pairs?
   • Are you targeting Windows-only, Linux-only, or cross-platform environments?
3. Error Handling:
   • How should failures be surfaced? (e.g., exceptions, logs, custom events).
   • Need retry logic? Use Laravel’s Retryable trait or a custom decorator.
4. Performance:
   • Will subprocesses be CPU-intensive? Monitor memory leaks (e.g., proc_open resource exhaustion).
   • Need process pooling? Implement a ProcessPool service wrapper.
5. Observability:
   • Require structured logging for subprocess output? Use Process::getOutput() + Laravel’s Log::info().
   • Need metrics (e.g., execution time)? Extend Process with Prometheus client.

Integration Approach

Stack Fit

• Laravel Ecosystem:
  • Artisan: Replace custom CLI commands with Process-backed commands (e.g., php artisan deploy:build).
  • Queues: Wrap Process in a job (e.g., RunDockerBuildJob) for async execution.
  • Events: Dispatch ProcessEvent for pre/post-execution hooks.
  • Testing: Use ProcessTestCase or mock Process with createMock(Process::class).
• Symfony Integration:
  • Dependency Injection: Bind Process to a custom interface (e.g., ProcessRunner) for testability.
  • Messenger: Use RunProcessMessage (v7.3+) for async workflows.
• DevOps Tools:
  • Docker/Kubernetes: Pass array env vars for multi-stage builds (e.g., ['BUILD_ARGS' => ['--arg1', '--arg2']]).
  • CI/CD: Replace shell_exec in GitHub Actions/GitLab CI with Process for consistency.
