ddd-layout

ddd layout is a open-source project meant to be used to as a start point, or an inspiration, for those who want to build Domain Driven Design applications in Golang.

NOTE: This is NOT intended to be a definitive solution or a production ready project

Architecture overview

Layers

• presentation: http controllers, grpc provider, schedule task, message subscriber, console command.
• application: Orchestrates the jobs in the domain needed to be done to accomplish a certain "use case"
• Domain: Where the business rules resides
• infrastructure: Technologies concerns resides here (database access, sending emails, calling external APIs)

CQRS

CQRS splits your application (and even the database in some cases) into two different paths: Commands and Queries.

Command side

Every operation that can trigger an side effect on the server must pass through the CQRS "command side". I like to put the Handlers (commands handlers and events handlers) inside the application layer because their goals are almost the same: orchestrate domain operations (also usually using infrastructure services).

Query side

Pretty straight forward, the controller receives the request, calls the related query repo and returns a DTO (defined on infrastructure layer itself).
