Vercel Controller: a Node.js microservice for Vercel cache and deployments
Express 4 service with async job queue, smart deduplication, LRU cache, Helmet.js security, and 129 tests — called by Travel Panel whenever content changes
Vercel Controller wraps the Vercel API behind a stable interface for every service in the Moon Holidays platform. Express 4 + Helmet.js, async job queue with smart deduplication, LRU response cache with 88% hit rate, bearer token auth with timing-safe comparison, 129 tests, and auto-healing Docker. Travel Panel calls it whenever content changes to invalidate CloudFront and redeploy dependent frontends.
