Spring Modulith

Enforces modular architecture in Spring Boot through package conventions, event-driven communication, and verification tests.

Do NOT Load for general Spring Boot development without modular structure concerns.

When to Use

• Structuring modules with enforced boundaries or named interfaces
• Choosing between event-driven and direct API communication
• Setting up verification tests or architecture documentation
• Configuring module-aware Flyway or initialization order
• Migrating a monolith to modular architecture
• Debugging boundary violations or event publication failures
