Microservice in practice with Seneca js

Seneca.js implements microservices by routing JSON messages with pattern matching and swapping transports without changing business code via transport independence. Demo shows a single Node process split to HTTP/TCP, Express/Hapi middleware exposing API routes, and storage plugins (default in-memory). Real project: CoderDojo system with five services (dojo, user, event, badge, Salesforce) supporting ~100 clubs in 60 countries, the event plugin contains 23 patterns.
