SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Building scalable, maintainable backend APIs can drift into scattered rules and inconsistent domain logic. This skill applies Domain-Driven Design to ElysiaJS and MongoDB to keep code organized, testable, and evolvable.

Core Features & Use Cases

Domain-driven modeling with entities, value objects, aggregates, and domain services to enforce rich business rules.
Full-stack architectural layers (domain, application, infrastructure) wired to MongoDB via Mongoose for production-grade data persistence.
Bun runtime templates with authentication scaffolding and Better Auth integration for secure APIs.

Quick Start

Start by scaffolding a new ElysiaJS + MongoDB project and launching the Bun-based API server to observe the DDD-based modules in action.

FAQPage Schema

How do I structure an ElysiaJS backend with Domain-Driven Design and MongoDB?▼

Structure an ElysiaJS backend using distinct domain, application, and infrastructure layers. This approach models domains with entities and value objects, wiring application services to a MongoDB repository via Mongoose for scalable, maintainable APIs.

What's the best way to organize Mongoose repositories in a DDD architecture on Bun?▼

Organize Mongoose repositories as infrastructure adapters in a DDD architecture on Bun. This isolates data persistence from domain logic, keeping entities, value objects, and application use cases testable and independent of MongoDB implementation details.

Can I use ElysiaJS with Mongoose and Bun for production-grade APIs?▼

Yes, ElysiaJS works with Mongoose and Bun for production-grade APIs. This setup provides a clean architecture with authentication scaffolding, password hashing, and a repository implementation fully compatible with the Bun runtime.

How does Domain-Driven Design prevent scattered business logic in backend APIs?▼

Domain-Driven Design prevents scattered business logic by encapsulating rules within rich entities, aggregates, and domain services. This structural isolation ensures consistent domain modeling and keeps backend APIs testable and evolvable.

Does this DDD ElysiaJS skill include authentication scaffolding?▼

Yes, this DDD ElysiaJS skill includes authentication scaffolding. It integrates Better Auth and provides password hashing directly within the architectural layers to secure MongoDB-backed APIs running on the Bun runtime.

When do I need value objects and aggregates in a MongoDB backend?▼

You need value objects and aggregates in a MongoDB backend when enforcing rich business rules and maintaining strict consistency boundaries. Modeling domains with these DDD patterns prevents scattered logic and keeps application use cases cleanly separated from infrastructure adapters.
