Low-code, event-driven microservice using Node-Red (http://nodered.org)
Node-Red is an open source, low-code platform for building event-driven apps. Originally focused on the IoT space, it can be used for many different use cases. It is extensible with custom nodes and especially great for fast prototyping of microservices.
This service is an opinionated custom-wrapped version of node-red, specifically targeted to run inside Kubernetes clusters.
Some design choices:
- uses node-red "projects" to pull flows from an external git repository
- custom nodes can be dynamically installed
- As an NodeJS / express app:
npm install
npm run start
open http://0.0.0.0:8080/- Local build and run using Docker
docker build . -t node-red-service
docker run -p 8080:8080 node-red-service
open http://0.0.0.0:8080/
