Node-RED

Quick Start

1. Inštalácia: https://nodered.org/docs/getting-started/windows
   • Online Node-RED environment FRED: https://fred.sensetecnic.com/
2. START http://localhost:1880/
   • Start Dashboard http://localhost:1880/ui
3. Základy
   • Node-RED Guide http://noderedguide.com
   • Cookbook: https://cookbook.nodered.org/basic/map-between-different-number-ranges
4. Knižnice: obvykle radia cez npm (node package manager), ale mne to velmi neslo, preto odporucam postup priamo z Node-RED menu: Settings -> Palette -> Install
5. Ukladanie: vytvorené flows sa nikam extra neukladajú, ale ak by to náhodou spadlo, prídete o ne. Preto odporúčam cez Menu -> Export uložiť to čo potrebujete
6. Koniec: Ctrl+C
