cloudflare-full-stack-integration

Connect a React frontend to a Cloudflare Worker backend by configuring CORS in your Worker middleware, attaching Clerk JWT tokens automatically in your API client, and verifying tokens server-side using Clerk's JWT validation. This Skill provides templates and middleware patterns for end-to-end integration.

CORS and token handling require three components: CORS middleware in your Worker to accept frontend requests, automatic JWT attachment in your API client, and proper preflight response configuration. This Skill includes ready-to-use templates for both frontend and backend that handle these together.

Yes. Clerk JWT verification runs in your Worker middleware to authenticate requests, then your verified token provides access to D1 databases via Worker bindings. This Skill covers the full flow including environment variable configuration for development and production.

Configure wrangler.jsonc with D1 and KV bindings, use Vite plugin configuration for frontend access, and manage secrets separately in development and production. This Skill provides complete wrangler.jsonc and vite.config.ts templates that prevent common env-var and binding access issues.

401 and CORS errors typically stem from incorrect middleware ordering, missing token attachment in API requests, or misconfigured CORS headers. This Skill diagnoses these issues and shows the exact middleware sequence and client setup needed to prevent them.

Use the provided frontend and backend templates with Hono framework, configure wrangler.jsonc and vite.config.ts, then run the dev server. This Skill includes quick-start scaffolding that sets up the full integration so you start with a working foundation.
