Common Scripts

npm run dev                 # Start Vinext dev server
npm run check               # Type-check without emitting files
npm run build               # Build production output
npm run deploy              # Build and deploy to Cloudflare Workers
npm run cf-types            # Generate Cloudflare binding types

npm run scrape              # Scrape ChatGPT app data
npm run scrape:claude       # Scrape Claude connector data

Deployment

Deployment uses Vinext's Cloudflare Workers target:

npm run deploy

In non-interactive environments, Wrangler requires a Cloudflare API token:

export CLOUDFLARE_API_TOKEN=...
npm run deploy

The Worker configuration lives in wrangler.jsonc. Generated deploy output is written under dist/.
