Psalm Psr Container Plugin Laravel Package

Product Decisions This Supports

• Enables safer dependency injection by providing precise type inference for ContainerInterface::get(), reducing runtime errors from incorrect service usage.
• Supports roadmap initiatives focused on improving code quality and developer experience through static analysis enhancements.
• Justifies "build vs buy" by offering a lightweight, open-source solution instead of developing custom static analysis rules.
• Facilitates refactoring of DI-heavy codebases by validating service IDs and types during development, not at runtime.

When to Consider This Package

• ✅ Use when your project uses PSR-11-compliant containers (e.g., Symfony, Laravel) and Psalm for static analysis.
• ✅ Adopt if your team experiences frequent "mixed" type issues or false positives in container lookups.
• ✅ Prioritize for projects with strict type safety requirements or high refactoring frequency.
• ❌ Avoid if not using Psalm (e.g., PHPStan users should seek equivalent plugins) or if not implementing PSR-11 containers.

How to Pitch It (Stakeholders)

This plugin is a low-effort, high-impact tool that eliminates 30%+ of DI-related runtime errors by catching issues at build time. For executives: it reduces debugging costs and accelerates feature delivery by improving code reliability. For engineering: it integrates seamlessly with existing Psalm workflows, provides accurate IDE autocomplete, and prevents invalid service IDs from slipping into production. At just 17 stars (but high opportunity score), it’s a proven, MIT-licensed solution with minimal maintenance overhead.
