Node.js as a feature-flipping supervisor through Git
summary
Claims a deployable system where a bare Git repo plus post-receive hook scripts push events into a Node.js “coordinator” built on streams and sockets which signals workers to run migrations, restart, or reload configs. It uses npm migration scripts, feature flags and ACLs shipped in signed tokens (JWT-signed payload), a simple broker/circuit for fault tolerance, and client push + service-worker updates. Demonstrates dynamic endpoints and lazy code loading with dynamic import so flags can flip without full redeploy; warns against centralized flag servers.
