Building a Domain-Driven Go REST API (And Why It Scales Better Than Flat Structure)

Most Go backend projects start the same way. A main.go , a router, a database connection, and then a slow drift into a structure that technically works but becomes painful to extend after the third or fourth feature. I've been there enough times that I finally sat down, extracted the architecture from a production project I was happy with, and published it as an open-source boilerplate. This post explains the architecture, why Domain-Driven Design (DDD) fits Go surprisingly well, and how the boilerplate is structured so you can hit the ground running on your next project.

That reputation is mostly deserved for the full tactical DDD toolkit (aggregates, value objects, domain events). But the core idea of DDD is simple and language-agnostic: The domain model is the center of your application
