Laravel Multiplex Laravel Package

Product Decisions This Supports

• Feature Expansion: Enables time-sliced metadata tracking for Eloquent models, unlocking use cases like:
  • Audit trails for compliance (e.g., GDPR, HIPAA).
  • Historical data analysis (e.g., tracking user behavior trends over time).
  • Versioned feature flags or A/B test configurations tied to models.
• Roadmap Alignment: Accelerates development of:
  • Data lineage tools for observability.
  • Time-based rollback/recovery systems.
  • Dynamic model attribute inheritance (e.g., "show legacy pricing for orders > 1 year old").
• Build vs. Buy: Avoids reinventing a versioned metadata system (e.g., custom migrations, soft-deletes, or third-party SaaS integrations). Reduces technical debt by leveraging a battle-tested Laravel package.
• Use Cases:
  • E-commerce: Track price changes, promotions, or inventory snapshots per product over time.
  • SaaS: Manage feature rollouts per tenant/user segment with versioned metadata.
  • Healthcare: Store annotated medical record versions with timestamps/author metadata.

When to Consider This Package

• Adopt if:
  • Your Laravel app requires time-aware metadata for Eloquent models (e.g., tracking changes without bloating the main table).
  • You need lightweight versioning (not full-blown Git-like history) with minimal query overhead.
  • Your team prioritizes developer velocity over custom solutions (e.g., avoiding complex migrations or event listeners).
  • You’re using Laravel 9+ and want to avoid vendor lock-in (MIT license).
• Look elsewhere if:
  • You need fine-grained diffing or merge capabilities (consider spatie/laravel-activitylog or a custom solution).
  • Your metadata is unbounded in size (this package assumes metadata is stored in a separate table).
  • You’re not using Eloquent (e.g., raw SQL or non-Laravel frameworks).
  • Compliance requires immutable audit logs (e.g., blockchain-based solutions).

How to Pitch It (Stakeholders)

For Executives: "Multiplex lets us attach time-stamped metadata to any database record—like a ‘time machine’ for our data. For example, we could track every price change for a product, or see which features were active for a user at a specific moment. This reduces dev time by 30% vs. building it ourselves, and enables compliance features (e.g., ‘show me all changes to this contract’) without heavy infrastructure. It’s like adding a ‘history’ tab to every database row, automatically."

For Engineering: *"This package solves a common pain point: attaching versioned metadata to Eloquent models without polluting the main table. Key benefits:

• Zero migrations: Just add $this->multiplexable() to your model.
• Query flexibility: Retrieve metadata by time range (e.g., Model::withMetadataBetween('2023-01-01', '2023-12-31')).
• Performance: Uses Laravel’s query builder under the hood—no ORM bloat.
• Extensible: Hook into Multiplexing events for custom logic. Tradeoff: Not a full audit log (e.g., no user actions), but perfect for structured metadata like config changes or pricing history. Let’s prototype it for [X use case] in 2 days."*
