How is money/currency handled in this NestJS skill?

The skill enforces the use of string types in DTOs combined with the big.js library for all arithmetic calculations to avoid floating-point precision errors.

Why does this skill use @sellernote decorators instead of standard class-validator?

These specialized decorators wrap validation and Swagger documentation into a single, consistent interface tailored for the Sellernote ecosystem, ensuring unified API specs.

What is the Sellernote 3-layer architecture enforced by this skill?

It is a structural convention dividing logic into Controllers (HTTP handling), Services (Business Logic), and Repositories (Data Access) to ensure strict separation of concerns and maintainability.

Can I use this for projects that aren't in a monorepo?

Yes, while the skill includes monorepo dependency rules, its core patterns for DTOs, Services, and Controllers apply to any NestJS project following these conventions.

Desarrollo de API

Streamlines NestJS backend development following strict 3-layer architecture and Sellernote-specific conventions.

This skill automates the creation and modification of NestJS API components—including controllers, services, repositories, and DTOs—while enforcing the Sellernote 3-layer architecture. It ensures consistent data validation using specialized decorators, handles complex money arithmetic via big.js, and maintains strict monorepo dependency rules. By automating boilerplate and enforcing domain-specific conventions, it helps developers build scalable, secure, and well-documented RESTful APIs that align with enterprise-grade standards.
