# 2019-01-16: @jvonau's PR #1403 moved installation of Node.js (8.x for now) &
# npm to roles/nodejs/tasks/main.yml, triggered by roles/nodered/meta/main.yml
# BRUTAL but ensures consistency across OS's / distros like Raspbian Desktop & Ubermix that often include an older version of Node-RED
- name: ASK apt/yum/dnf TO REMOVE PRE-EXISTING Node-RED (IF IT WAS INSTALLED BY OS PKG MANAGER)
package:
name: nodered
state: absent
# Too brutal, as this removed customizations on graphical desktop OS's e.g.
# Raspbian Desktop's:
# 1. Node-RED's icon (Raspberry Menu in top-left -> Programming -> Node-RED)
# 2. scripts like {node-red-start, node-red-stop, node-red-log} in /usr/bin
# 3. other changes per /usr/bin/update-nodejs-and-nodered summarized at
# https://nodered.org/docs/hardware/raspberrypi for example low-memory
# flag --max_old_space_size=256 for unit file (any reason we use 128?)
