@cardog/corgi/examples/cloudflare-worker.js

⚡ The fastest and most lightweight open-source VIN decoding library. Fully offline, TypeScript-first, with comprehensive NHTSA VPIC database integration for Node.js, browsers, and Cloudflare Workers.

/**
 * Example Cloudflare Worker using the CORGI VIN Decoder with a D1 database
 * 
 * To use this example:
 * 1. Create a D1 database using the sqlite-to-d1.js script
 * 2. Configure your wrangler.toml to use the D1 database
 * 3. Deploy the worker with `npx wrangler deploy`
