Product Decisions This Supports

Enables efficient runtime access to dependency version information without I/O overhead, critical for features like version-aware caching, debugging endpoints, and deployment validation.
Eliminates need to build custom version-checking logic (build vs buy), reducing technical debt and maintenance costs.
Supports use cases where dependency versions must be dynamically referenced in application logic (e.g., generating cache keys based on specific package versions, or displaying dependency details in admin panels).

When to Consider This Package

Adopt when your PHP project uses Composer and requires runtime access to installed package versions for performance-sensitive operations (e.g., caching, diagnostics, or deployment scripts).
Consider if you need to avoid runtime I/O for version checks (e.g., in high-throughput applications where reading composer.lock on each request would be costly).
Look elsewhere if your project doesn't use Composer, if version checks are only needed during build time (e.g., CI/CD), or if you need dependency tree analysis (use tools like composer show instead).

Executives: "This lightweight package solves a critical performance bottleneck for version-dependent features. By eliminating runtime I/O for dependency version checks, it ensures our application scales efficiently while reducing development time—freeing engineering resources for higher-value work. Backed by Tidelift for enterprise support and proven in production with 3K+ stars."
Engineering: "Simple Composer dependency with zero runtime overhead. Pre-compiles version data during installation, so calls to Versions::getVersion() are in-memory and blazing fast. Handles edge cases like --classmap-authoritative installs and has active maintenance (security updates, PHP 8.5 support). Integrates in minutes with no code changes beyond a single method call."
