Platform kernel

Rumuze Core: a NestJS platform kernel built on a transactional outbox

A NestJS API built around a transactional outbox, a webhook engine and Socket.IO realtime, with a Next.js dashboard on top.

Event flow from API to webhooks and realtime

What the kernel provides

  • An event bus for domain events and communication between modules
  • A transactional outbox so events are delivered once the data they describe is committed
  • A webhook engine for secure inbound webhooks and reliable outbound delivery
  • A realtime engine on Socket.IO, fanned out through Redis
  • Platform metrics and trace id propagation

How it is built

  • A monorepo with a NestJS API and a Next.js 14 dashboard
  • Prisma on PostgreSQL; Redis for realtime fan-out
  • Nginx as the reverse proxy for two subdomains, one for the API and one for the dashboard
  • Docker Compose for local development and production

How it is operated

  • TLS certificates are issued and renewed automatically through Let's Encrypt
  • The running kernel version is exposed on an internal endpoint, separate from the health check
  • CORS origins and secrets are configured through environment variables
