Contracts Laravel Package

Product Decisions This Supports

• Build vs Buy: Eliminates need to create custom abstraction layers for common patterns (caching, events, service location), saving engineering effort while ensuring compatibility with Symfony and community implementations
• Roadmap Flexibility: Enables future-proofing by decoupling core domain logic from framework-specific implementations (e.g., swapping Laravel's cache driver for Redis without touching business logic)
• Cross-Platform Integration: Supports using third-party libraries that implement Symfony contracts (e.g., non-Symfony cache providers) while maintaining consistency with Symfony-based services
• Technical Debt Reduction: Prevents framework lock-in in service layers by using standardized interfaces instead of concrete classes (e.g., CacheInterface instead of Illuminate\Cache\Repository)

When to Consider This Package

• Adopt when: Building multi-framework applications, creating reusable libraries needing framework-agnostic interfaces, or planning long-term architecture flexibility (e.g., potential migration from Laravel to Symfony)
• Avoid when: Working on small projects with no need for abstraction, using only one fixed implementation (e.g., exclusively Laravel's cache without future switch plans), or when team lacks familiarity with contract-based design patterns
• Look elsewhere for: Projects requiring PSR-only compatibility (Symfony Contracts add richer semantics beyond PSRs), or when concrete implementations with built-in configuration are needed (this package contains only interfaces)

How to Pitch It (Stakeholders)

Executives: "This package future-proofs our architecture by eliminating vendor lock-in—our core business logic works with any implementation of standardized interfaces (e.g., cache, events), reducing migration costs and technical debt. With MIT licensing and 3,900+ stars, it’s a proven industry standard that accelerates feature delivery while cutting long-term maintenance expenses."

Engineering: "By type-hinting against Symfony Contracts (e.g., CacheInterface), we write framework-agnostic code that works seamlessly with Laravel, Symfony, or third-party libraries. This simplifies testing via mock implementations, enables smooth cache/backend swaps, and aligns with DI best practices—no custom glue code needed. Laravel’s autowiring aliases make adoption trivial with minimal setup."
