A great overview about #jMolecules by Otavio Santana on #DZone: dzone.com/articles/enh...
Enhancing Software Governance and Quality With jMolecules
jMolecules uses annotations to enforce architectural rules, prevent software erosion, simplify validation with tools like ArchUnit. It supports DDD, CQRS, etc.

I've added a #jMolecules-based persistence approach to @bitboss.bsky.social' repository, showcasing various aggregate persistence approaches to outline how streamlined and free of persistence artifacts a domain model can be and still persisted via #JPA out of the box. ☕️⚗️

Double sneak preview! #jMolecules 2.0 is going to introduce a declarative stereotype concept for predefined ones (DDD, Spring) and custom ones declared in your projects. The #STS team has a prototype to turn that information into a project tree for higher-level project navigation. ☕️⚗️
An image displaying a tree structure of a software application, grouping various components by their architectural stereotype, such as Domain Event Handlers, Aggregate Roots, Services, Entities.

Update on the logical project view coming in #STS (flip your #SpringBoot tools to pre-release versions in #VSCode):

- Alphabetic sorting of the stereotypes per level
- Icons! (at least for some of them) 🔥

Up next: #SpringModulith groupings by application module.

⚗️🍃📦 #jMolecules #DDD #Spring
A refined variant of the logical structure view in VSCode displaying application structure based on architectural, design and technology stereotypes in a tree-like structure.
