What problem does it solve?

This guide helps teams structure NestJS projects using a Domain-Driven Design (DDD) approach and an Event Bus pattern to improve modularity, scalability, and maintainability.

Core Features & Use Cases

• DDD-based organization: Clear separation of domain, application, infrastructure, and presentation layers with a consistent folder layout.
• Event Bus integration: Demonstrates how to wire domain events to bus-based messaging for decoupled, reactive workflows.
• Layered architecture template: Prescribes a familiar structure: domain, application, infrastructure, and presentation, plus a libs area for shared code.
• Best practices: Encourages barrel exports, framework-agnostic domain logic, and service boundaries that support testability and collaboration.

Quick Start

Organize your NestJS project using the provided directory layout and begin implementing modules according to the template.
