Event Dispatcher Laravel Package

Product Decisions This Supports

• Enables interoperability between Laravel and other frameworks (e.g., Symfony), reducing integration costs for third-party libraries and avoiding custom adapter code.
• Supports "build vs buy" decisions by allowing teams to swap event dispatcher implementations (e.g., Symfony's dispatcher vs. custom) without refactoring core logic.
• Future-proofs architecture by aligning with PHP-FIG standards, ensuring compatibility with evolving ecosystem tools and reducing vendor lock-in.
• Facilitates microservices communication via consistent event contracts, critical for distributed systems where services may use different frameworks.

When to Consider This Package

• Adopt when building reusable packages/middleware that must work across multiple PHP frameworks or integrate with PSR-14-compliant external services.
• Use when planning long-term infrastructure flexibility (e.g., framework migration paths) or when third-party libraries explicitly require PSR-14 interfaces.
• Consider when standardizing event handling across teams to enforce consistency in large-scale applications.
• Avoid if your project is entirely contained within a single framework (e.g., pure Laravel app with no external PSR-14 dependencies) and native event patterns suffice. Also skip if you need advanced features beyond standard interfaces (e.g., specialized dispatching logic), as implementations vary.

How to Pitch It (Stakeholders)

• Executives: "This PSR-14 standard reduces technical debt by ensuring our event system integrates seamlessly with industry tools and frameworks. It eliminates costly custom integrations with third-party services, saving time and resources while future-proofing our architecture against vendor lock-in."
• Engineering: "By injecting PSR-14 interfaces instead of framework-specific classes, we decouple code from Laravel’s Event system, enabling zero-downtime swaps of event dispatchers (e.g., Symfony or custom) with zero code changes. Laravel already supports this natively—adopting it requires minimal effort and unlocks compatibility with 100+ open-source libraries."
