SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the challenge of creating inconsistent, insecure, or poorly performing API endpoints. It guides the development of RESTful APIs that are easy to understand, consume, and maintain, ensuring reliable communication between your backend and frontend services.

Core Features & Use Cases

  • RESTful Design: Ensures API endpoints follow standard HTTP methods, resource-based URLs, and status codes.
  • Versioning & Query Parameters: Guides implementation of API versioning and flexible data retrieval.
  • Use Case: When creating a new API endpoint for fetching user data, use this skill to ensure the AI designs a /api/v1/users/{id} endpoint with appropriate GET method, handles query parameters for filtering, and returns standard HTTP status codes.

Quick Start

Design and implement a new RESTful API endpoint for creating a 'product' resource, ensuring proper HTTP methods and status codes.

FAQPage Schema
How do I design RESTful API endpoints that follow HTTP standards?

RESTful API endpoints use standard HTTP methods (GET, POST, PUT, PATCH, DELETE) with resource-based URLs, proper status codes, and versioning. Design endpoints like `/api/v1/users/{id}` with appropriate methods to ensure consistency, security, and maintainability across your backend services.

What's the best way to handle API versioning and query parameters for filtering?

API versioning through URL paths (e.g., `/api/v1/`) combined with query parameters enables flexible data retrieval. Use query parameters for filtering, sorting, and pagination—like `?filter=name&sort=date&page=1`—to let clients request exactly what they need without breaking existing integrations.

How do I implement nested resource routes and relationships in Laravel APIs?

Nested routes represent resource relationships in your URL structure, such as `/api/v1/users/{id}/posts`. In Laravel, define these in `routes/api.php` and use API resource controllers to handle the logic, ensuring proper HTTP methods and status codes for each nested endpoint.

What HTTP status codes should I return from different API operations?

Return appropriate status codes for each operation: 200 for successful GET/PUT, 201 for successful POST, 204 for successful DELETE, 400 for bad requests, 404 for not found, and 429 for rate-limited requests. Correct status codes help clients understand the result and handle errors properly.

Can I add rate limiting and pagination to Laravel API endpoints?

Yes. Laravel supports rate limiting through middleware configuration and pagination through query parameters. Implement both in your API controllers to control traffic, prevent abuse, and return paginated results with metadata about total items and current page position.

Do I need to transform API responses using resource classes?

API resource classes standardize response formatting, allowing you to control which fields are exposed, transform data structures, and add computed properties. Using resource classes in Laravel ensures consistent, secure JSON responses across all endpoints.
