SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires ky, openapi-typescript, openapi-fetch, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses the complexity of frontend API interactions by providing a structured approach to type safety, error handling, and efficient data fetching, preventing common pitfalls in modern web applications.

Core Features & Use Cases

  • Type Safety: Ensures data consistency from API response to component rendering.
  • Centralized Error Handling: Manages network errors, authentication issues, and API-specific errors gracefully.
  • Efficient Data Fetching: Integrates with libraries like TanStack Query for caching, deduplication, and request cancellation.
  • Use Case: Develop a complex e-commerce frontend where product data, user authentication, and order processing all rely on robust API calls, ensuring a seamless and error-free user experience.

Quick Start

Use the api-layer skill to create a typed fetch wrapper for making authenticated API requests.

FAQPage Schema
How do I build a type-safe frontend API layer with TypeScript?

Build a type-safe frontend API layer by using typed fetch wrappers and OpenAPI codegen to generate TypeScript types from API responses, ensuring data consistency from the server to component rendering.

What's the best way to handle authentication token refresh in a TypeScript HTTP client?

Handle authentication token refresh in a TypeScript HTTP client by implementing custom fetch wrappers that intercept expired token responses and automatically execute refresh mechanisms before retrying the failed requests.

How does OpenAPI codegen improve frontend data fetching?

OpenAPI codegen improves frontend data fetching by automatically generating TypeScript types from API specifications, which eliminates manual type definitions and ensures compile-time safety across your HTTP client requests.

Can I use ky with TanStack Query for API error handling?

Yes, you can use ky with TanStack Query for API error handling by wrapping ky requests in custom error classes that centrally manage network failures and authentication issues before passing them to the query cache.

How do I organize frontend API modules for a complex web application?

Organize frontend API modules by structuring them into dedicated typed wrappers for specific domains like user authentication and order processing, centralizing error handling and request cancellation logic for maintainability.

How do I implement CSRF protection and request cancellation in an HTTP client?

Implement CSRF protection and request cancellation in an HTTP client by configuring custom fetch wrappers to automatically attach security tokens to requests and integrating AbortController for efficient data management.
