Spring Modulith – Spring for the Architecturally Curious Developer

on YouTube ↗50m

" summary

Spring Modulith analyzes top-level packages to build a model of logical modules, generates AsciiDoctor/C4 diagrams and module canvases, and verifies encapsulation by treating base packages as exported APIs and applying ArcUnit-style rules. It boots per-module Spring Boot slices via application-module tests, can include direct or transitive dependent modules, and shifts cross-module calls to event-driven communication with transactional async listeners plus an event publication registry to avoid lost events. It adds a fluent scenario API for async integration tests, supports jMolecules DDD types, is experimental but has a production predecessor and aims to graduate.
