Chunker Laravel Package

Product Decisions This Supports

• Memory-efficient file/string processing: Enables handling large files (e.g., logs, CSV exports, media uploads) without memory overload by chunking data safely.
• Multi-byte character integrity: Critical for internationalized apps (e.g., e-commerce, CMS) where corrupted UTF-8/Unicode breaks UX (e.g., € → ?).
• Streaming APIs/background jobs: Supports Laravel Queues, Livewire, or API responses (e.g., chunked file downloads) without loading entire files into memory.
• Build vs. buy: Avoids reinventing wheel for multi-byte-safe chunking (vs. custom regex/string manipulation).
• Roadmap: Enables future features like:
  • Large file uploads (e.g., video processing).
  • Real-time data pipelines (e.g., log tailing).
  • Localization tools (e.g., translation memory chunking).

When to Consider This Package

• Use this when:

  • Processing files >1MB (e.g., CSV, JSON, media) in PHP.
  • Working with multi-byte encodings (UTF-8, UTF-16) where byte-splitting risks corruption.
  • Building streaming APIs, background jobs, or memory-sensitive apps.
  • Laravel apps needing chunked file handling (e.g., Storage::disk()->readStream()).

• Look elsewhere if:

  • Files are small (<1MB) and encoding isn’t critical (use native fread()).
  • You need random access (this is sequential-only; use SplFileObject for seekable streams).
  • Performance is critical (this adds ~10–20% overhead vs. raw file_get_contents()).
  • You’re using non-PHP (e.g., Node.js/Python; use native libraries instead).

How to Pitch It (Stakeholders)

For Executives: "This package solves a hidden technical debt risk: corrupted multi-byte characters in large files (e.g., € → ?) when chunking for memory efficiency. It’s a drop-in fix for Laravel apps handling uploads, logs, or exports—reducing memory usage while preserving data integrity. Low risk (MIT license, 7 stars), high ROI for global apps or high-volume data pipelines."

For Engineers: *"A battle-tested, multi-byte-safe chunker for PHP 7.4+. Key benefits:

• Safe: Handles UTF-8/Unicode without ? artifacts.
• Simple: Replaces file_get_contents() with while ($chunk = $chunker->current()).
• Flexible: Works for files and strings, with custom chunk sizes.
• Laravel-friendly: Integrates with Queues, Storage, and Livewire. Tradeoff: ~10% overhead vs. raw streams, but worth it for correctness. Ready to composer require and use in 10 minutes."*
