SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the process of designing, implementing, and validating RESTful API endpoints, ensuring consistency, security, and maintainability in backend development.

Core Features & Use Cases

  • API Design Patterns: Provides conventions for RESTful actions, methods, and routes.
  • Input Validation: Integrates Yup schemas and middleware for robust data validation.
  • Error Handling: Offers standardized response formats and error codes for consistent API behavior.
  • Use Case: When building a new feature that requires user data management, use this skill to define the CRUD operations, implement input validation for user registration, and ensure proper error responses for failed requests.

Quick Start

Use the api-design skill to create a GET endpoint for retrieving a list of users, ensuring input is validated against a predefined schema.

FAQPage Schema
How do I design REST API endpoints with Koa and Firebase Functions?▼

Designing REST API endpoints with Koa and Firebase Functions involves defining structured routing and controller patterns, standardizing response formats, and sanitizing client-facing data. This approach ensures maintainability and consistency across backend operations.

What is the best way to validate API input in a Koa backend?▼

Validating API input in a Koa backend is best achieved by integrating Yup schemas with middleware. This enforces robust data validation before requests reach controllers, preventing invalid data processing and ensuring structured error responses.

How do I standardize error handling and response formats for a RESTful API?▼

Standardizing RESTful API error handling requires implementing consistent response formats and error codes. This ensures uniform API behavior across endpoints, making client-side error parsing predictable and simplifying debugging.

Can I use Yup schemas for data validation in Firebase Functions?▼

Yes, you can use Yup schemas for data validation in Firebase Functions. The integration leverages middleware within the Koa environment to validate incoming requests, ensuring proper context handling and sanitized data output.

How do I implement pagination strategies in a REST API?▼

Implementing pagination strategies in a REST API requires establishing conventions for limiting and offsetting data retrieval. This optimizes payload sizes and database queries when returning lists of resources to clients.
