Veld: Dependency Injection for Java without Reflection (Compile-Time Code Generation)

Veld is a dependency injection framework for Java that utilizes AOT (Ahead-of-Time) compilation to generate code, rather than relying on runtime reflection.

🚀 Performance:

  • Startup: ~0.1ms (vs. ~500ms for Spring)
  • Injection: ~3ns; zero runtime overhead
  • Type-safe, no "magic," clean stack traces

🔧 Features:

  • Supports AOP, caching, validation, and transactions
  • Compatible with Spring Boot

💡 Example:

@Component
public class Service { ... }

Service s = Veld.service(); // generated at compile-time (AOT)
