Structure your NestJS project by separating domain, application, infrastructure, and presentation layers into a consistent folder layout. This DDD-driven approach provides explicit module boundaries and documented conventions to improve modularity and maintainability.

The Event Bus pattern in a layered NestJS architecture wires domain events to bus-based messaging, creating decoupled and reactive workflows. It separates event triggering from event handling to improve modularity across different application layers.

You need a DDD folder structure for mid- to large-scale enterprise applications where multiple teams collaborate. It enforces explicit module boundaries, framework-agnostic domain logic, and clear service boundaries to support testability and scalability.

Organize shared code in a dedicated libs area within your DDD NestJS project. This layered architecture template encourages using barrel exports and framework-agnostic domain logic to maintain clean dependencies across modules.

This DDD NestJS template targets mid- to large-scale enterprise applications rather than small projects. Its strict layered architecture, explicit module boundaries, and Event Bus pattern introduce structural overhead designed for team collaboration and scalability.

Use an Event Bus for domain events in NestJS to achieve decoupled, reactive workflows across your application layers. It separates domain logic from infrastructure messaging, improving testability and allowing modules to react independently.
