Does it support message brokers like Kafka?

Yes, the skill includes patterns for event externalization, allowing internal domain events to be published to Kafka or AMQP automatically.

How does Spring Modulith handle cross-module communication?

It promotes loose coupling by using domain events and the @ApplicationModuleListener annotation instead of direct bean injection across module boundaries.

Can this skill help prevent architectural regression?

Yes, it provides patterns for using ApplicationModules.verify() in your test suite to catch unauthorized dependencies between modules automatically.

What version of Spring Boot does this skill support?

This skill is specifically designed for Spring Boot 4 and utilizes Spring Modulith 2.0 implementation patterns.

API Development

Implements modular monolith architectures using Spring Modulith 2.0 to enforce bounded contexts and event-driven communication.

About

This skill empowers developers to build scalable and maintainable modular monoliths by leveraging Spring Modulith 2.0 and Spring Boot 4. It provides comprehensive guidance on structuring application modules as DDD bounded contexts, enforcing strict package boundaries, and implementing asynchronous, event-driven communication between modules. By automating module verification tests and providing patterns for externalizing events to brokers like Kafka or AMQP, this skill helps teams avoid 'big ball of mud' architectures while maintaining the simplicity of a single deployment unit.
