I've recently learnt how to run Node-red on Intel Edison following attending one of the Intel Edison workshop hosted by the folks at IBM Bluemix (Twitter: #BluemixIoTWorkshop hosted by @IICHursley).
This Instructable aims to capture some of the main steps to get Node-red installed on the Intel Edison device - so that going forward whenever you power up your Edison kit, Node-red is run automatically - and you are able to access Node-red via a URL like this:
(Replace edison-device-name with your edison name)
Issues the following commands to install node-red and pm2.
npm install -g --unsafe-perm node-red
npm install -g --unsafe-perm pm2
