Filesystem Laravel Package

Technical Evaluation

Architecture fit: Standalone component designed for Laravel ecosystem but usable outside it; requires illuminate/collections, contracts, macroable, and support packages. Ideal for Laravel projects where it integrates natively with config and DI, but introduces dependency overhead for non-Laravel apps.
Integration feasibility: High for Laravel projects (pre-installed), moderate for standalone use (Composer install + manual dependency management). Simple API with minimal boilerplate for basic file operations but requires handling Flysystem-specific configurations for cloud drivers.
Technical risk: Moderate. Low standalone adoption (0 dependents) suggests limited community validation outside Laravel. Tight coupling with other Illuminate packages could cause version conflicts in non-Laravel projects. The symfony/filesystem dependency introduces exception handling complexity (IOExceptionInterface vs. PHP core exceptions).
Key questions:

• Is standalone usage officially supported, or is this a de facto subtree split with no maintenance guarantees outside Laravel?
• How are breaking changes in Flysystem (e.g., v3 → v4) handled in this package?
• What’s the upgrade path for projects using older Laravel versions that rely on legacy Flysystem interfaces?

Integration Approach

Stack fit: Optimized for Laravel but works in any PHP 8.3+ project. Integrates seamlessly with Flysystem-backed storage (S3, FTP, etc.) and Laravel’s Storage facade. Requires manual setup of disks/config for non-Laravel projects.
Migration path:

1. Replace raw file_get_contents()/file_put_contents() with $fs->get()/$fs->put() for basic reads/writes.
2. Substitute directory operations (e.g., scandir()) with $fs->allFiles() or $fs->directories().
3. Adopt atomicPut() for critical writes to avoid partial updates.
4. Use storage_path()/base_path() for path resolution to avoid CLI/HTTP discrepancies.
   Compatibility: Requires PHP 8.3+, Symfony Finder 7.4+/8.0+, and other Illuminate packages. Non-Laravel projects must manually register filesystem drivers (e.g., S3 credentials via FilesystemManager).
   Sequencing:
5. Install via Composer (composer require illuminate/filesystem).
6. Replace non-critical file operations in tests first.
7. Gradually migrate core logic (e.g., user uploads
