SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill standardizes API endpoint patterns in NestJS projects, reducing boilerplate and promoting consistent responses and error handling.

Core Features & Use Cases

  • Standardized ResponseService patterns for success, error, and paginated results.
  • Controller and DTO templates that enforce consistent routing, validation, and data shaping.
  • Centralized error handling and HTTP status conventions to improve API reliability.
  • Use Case: Rapidly scaffold a new resource (for example, a product resource) using a single source of truth for controllers, DTOs, and responses.

Quick Start

Install a NestJS project or use an existing one. Copy the ResponseService, Controller pattern, DTO patterns, and exception filters into your module. Create a new resource by following the Controller, DTO, and Service scaffolding examples. Run the app and verify endpoints and error handling.

FAQPage Schema
How do I standardize API endpoint patterns in NestJS to reduce boilerplate?

Standardize NestJS API endpoints by applying consistent controller, DTO, and response service templates. This enforces predictable routing, validation, and centralized error handling across multiple resources to reduce boilerplate.

What is the best way to handle errors and HTTP status codes consistently in a NestJS backend?

The best way to handle errors in a NestJS backend is to enforce centralized exception filters and proper HTTP status conventions. This creates a standard response structure for reliable error handling across all API endpoints.

How do I scaffold a new API resource with standardized controllers and DTOs?

Scaffold a new API resource by copying ResponseService, controller, and DTO templates into your module. This creates a single source of truth for routing, data validation, and response shaping for the new resource.

How does a standardized response service pattern work for paginated API results?

A standardized response service pattern works by wrapping paginated API results in a consistent data structure. This ensures predictable behavior for success, error, and paginated payloads across all resources.

Can I use these API controller patterns in an existing NestJS project?

Yes, you can use these API controller patterns in an existing NestJS project. Simply copy the ResponseService, controller templates, and exception filters directly into your existing module to enforce consistency.

Why do I need DTO validation templates for my API endpoints?

You need DTO validation templates to enforce consistent data shaping and routing validation in your API endpoints. This prevents invalid data from reaching your services and standardizes request payloads across resources.
