Node-RED is a web-based flow-based development tool for visual programming APIs, hardware devices, and online services.

It was originally developed by IBM butt was made open source under the Apache License 2.0 in 2016.

The simplest way to get started is to use the Node-RED docker image. I use the following docker-compose.yml configuration with docker-compose to get started.

version: '3.3'

services:
  nodered:
    image: nodered/node-red-docker:latest
    labels:
      - "traefik.enable=true"
      - "traefik.port=1880"
      - "traefik.docker.network=traefik"
      - "traefik.frontend.rule=Host:nodered.example.com"
      - "traefik.frontend.redirect.entryPoint=https"
      - "traefik.frontend.auth.forward.address=http://auth/index.php"
    networks:
      - traefik
    expose:
      - "1880"
    restart: always
    volumes:
      - /var/volumes/nodered/data:/data

networks:
  traefik:
