How does this skill help with CORS errors?

It provides specific middleware templates that ensure CORS headers are applied in the correct order before API routes, handling both development and production origins.

What authentication providers are supported?

While optimized for Clerk with JWT verification, the architectural patterns can be adapted for other JWT-based auth providers like Kinde or Auth0.

How does it handle authentication race conditions?

It provides React hooks and components that check the Clerk 'isLoaded' state before attempting API calls, preventing 401 errors caused by missing tokens.

Does this skill work with the Cloudflare Vite plugin?

Yes, it includes configuration templates for @cloudflare/vite-plugin, allowing your frontend and Worker to run on the same port during development.

Is D1 database access included?

Yes, it provides patterns for accessing D1 through environment bindings in Hono and using parameterized queries to ensure security.

API Development

Streamlines the integration of React frontends with Cloudflare Workers using Hono, Clerk authentication, and D1 databases.

About

This skill provides production-tested architectural patterns and templates for building robust full-stack applications on the Cloudflare platform. It addresses the most common friction points in serverless development, including CORS misconfigurations, environment variable management between Vite and Workers, and authentication race conditions. By providing standardized fetch wrappers, Hono middleware, and Vite configurations, it ensures that frontend and backend components communicate securely and efficiently without the typical troubleshooting overhead associated with auth tokens and database bindings.

Key Features

2 GitHub stars
Unified development setup using @cloudflare/vite-plugin for single-port local testing.
Frontend API client wrappers that automatically attach Clerk session tokens to requests.
Standardized environment variable handling for both Vite (frontend) and Wrangler (backend).
Pre-configured Hono middleware for JWT verification and robust CORS handling.
Secure D1 database binding patterns with parameterized query templates.

Use Cases

Resolving persistent 401 Unauthorized or CORS errors between frontend and serverless backends.
