To create API endpoints in Elysia.js using Domain-Driven Design, you structure your code into domain models, application services, delivery routes, and repositories. This approach separates business logic from HTTP delivery, ensuring your endpoints remain maintainable and scalable.

You can generate OpenAPI documentation for TypeScript backend routes by applying OpenAPI annotations and metadata directly to your HTTP delivery routes. This provides automatic validation and detailed route descriptions for your API consumers.

The best way to scaffold an HTTP route with value objects and domain errors is to use a DDD-guided endpoint structure. This workflow defines repository interfaces and domain models aligned to the endpoint, reducing ambiguity and drift between business logic and API delivery.

Yes, this endpoint scaffolding workflow includes end-to-end testing for backend APIs. It covers domain, application, and delivery layers, plus basic E2E test scaffolds to ensure the newly created HTTP routes function reliably throughout the entire request lifecycle.

You do not need to manually define repository interfaces from scratch when adding an API endpoint. The structured creation process encapsulates requirements for repository interfaces alongside value objects and domain errors, automating the foundational DDD architecture setup.
