Signal Slot Laravel Package

Product Decisions This Supports

• Deciding whether to build or buy an event/notification layer. This package is a reference implementation of the signal/slot (observer) pattern, useful as a benchmark when weighing “adopt an existing library” vs. “use Laravel’s native Event/Listener system” vs. “build a thin internal bus.” In practice it mostly supports the build-or-use-native side of that decision.
• Architecture and modularity roadmap. The pattern itself — decoupled emitters and listeners — is a legitimate input to decisions about plugin hooks, audit logging, webhooks, and cross-module communication. Use it as a lens for designing those features, not as the runtime dependency.
• Legacy ecosystem triage. If you inherit a Zeta Components / eZ Publish codebase, this package informs decisions about keep-vs-replace and the sequencing of a migration to Laravel’s event system.
• Feature scope calls. It highlights a trade-off worth surfacing in planning: a hand-rolled or third-party dispatcher buys flexibility but adds a dependency to maintain, whereas framework-native events buy stability but tie you to Laravel’s conventions.
• Does not support most greenfield roadmap decisions. With 3 stars, 0 dependents, and a low viability score, it should not be the basis for a new platform or integration bet.

When to Consider This Package

Consider it only when:

• You are actively maintaining a legacy Zeta Components or eZ Publish application that already uses signal-slot, and the cost of ripping it out exceeds the cost of leaving it in place.
• You need a teaching or reference example of the observer pattern in PHP for documentation or architecture review.
• You have an extremely constrained, isolated subsystem where a zero-dependency, single-purpose dispatcher is acceptable and the code will not outlive that subsystem.

Look elsewhere when:

• You are building on Laravel. Use the native event dispatcher (Event::dispatch, listeners, subscribers, queued listeners). It is maintained, documented, and integrated with queues, broadcasting, and testing.
• You need framework-agnostic events. Use symfony/event-dispatcher or league/event for an actively maintained, widely adopted, PSR-compatible option.
• You require modern PHP support, security patching, or long-term maintenance — none of which this package plausibly offers at this adoption level.
• License clarity is a gate. The repository reports NOASSERTION, so legal review is mandatory before any commercial use; assume a blocking step until provenance is confirmed.
• You are optimizing for observability and performance at scale — the pattern is fine, but this implementation is not a defensible choice for high-throughput or instrumented systems.

How to Pitch It (Stakeholders)

For executives: This library implements an event/observer pattern — conceptually sound, but the package itself is effectively unmaintained, with negligible community adoption and no declared license. We do not recommend adopting it for new product work. The idea is already covered by capabilities we get for free in our Laravel stack, so adding this dependency would create maintenance and licensing risk without adding product capability. Recommended position: no new investment; treat as a legacy artifact.

For engineering: Favor Laravel’s native events and, where framework independence is required, symfony/event-dispatcher. If legacy code already depends on signal-slot, isolate it behind a small internal interface so callers are not coupled to the implementation, then migrate listeners incrementally. Flag the license ambiguity (NOASSERTION) to legal before any further dependency on it in distributed or commercial code.

Bottom line for the roadmap: low priority, low risk if untouched, non-trivial technical debt if expanded. Choose framework-native events for new features and schedule legacy replacement as background maintenance rather than a dedicated initiative.
