SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Designs and implements RESTful API endpoints that adhere to REST principles and web API conventions, reducing ambiguity and boilerplate in backend services.

Core Features & Use Cases

  • Endpoint design and routing rules that align with resource-based URLs and correct HTTP method mappings.
  • API versioning strategies and consistent status code / error formatting.
  • Guidance on middleware, request validation, and route configuration to ensure scalable, maintainable APIs.

Quick Start

Create a new REST endpoint under /api/v1/example with GET and POST methods and return appropriate HTTP status codes.

FAQPage Schema
How do I design RESTful API endpoints with proper HTTP methods and status codes?

Design RESTful API endpoints by mapping resource-based URLs to correct HTTP methods and enforcing consistent HTTP status codes. This approach reduces ambiguity and ensures your backend services align with standard web API conventions for scalable routing.

What is the best way to version REST API routes for scalable backend systems?

Version REST API routes by applying structured versioning strategies to your URL paths, such as /api/v1/. This maintains scalable and maintainable backend services by preventing breaking changes for existing clients.

How do I structure REST API responses for pagination and error formatting?

Structure REST API responses by applying consistent error formatting and pagination strategies to your JSON outputs. This ensures clients can reliably handle large datasets and interpret HTTP status codes across your service.

Do I need specific frameworks to implement REST API conventions and middleware?

No specific frameworks are required to implement REST API conventions and middleware. You can apply these resource-based routing rules and request validation strategies across any backend system to ensure maintainable API routes.

Why does my REST API return incorrect HTTP status codes for different endpoints?

REST APIs return incorrect HTTP status codes when endpoints lack enforced requirements for status code mappings. Applying strict web API conventions ensures your routes and controllers return appropriate responses for GET and POST operations.

Can I use this to create both GET and POST routes under a single API version?

Yes, you can create new REST endpoints like /api/v1/example with both GET and POST methods. The skill configures routing rules and controllers to handle multiple HTTP methods under the same versioned URL structure.
