⚙ Full Stack
Node.js/Express backend with Socket.IO for real-time updates, pluggable database layer (Redis, MongoDB, or Postgres), server-rendered + client-hydrated templates.
📈 Scaling Analysis
Socket.IO real-time state requires sticky sessions or a Redis adapter for multi-replica websocket fan-out; once that's configured the app tier scales horizontally cleanly, with the database choice determining the ultimate ceiling.
🚀 Running on Nexlayer
Single nodebb pod with a postgres pod (postgres.pod:5432) or mongo pod (mongo.pod:27017) depending on chosen DB adapter, plus a redis pod (redis.pod:6379) for session/socket state if scaling to multiple replicas. Official image is Docker Hub library — mirror via mirror.gcr.io/library/nodebb.
