Node-RED is a Flow Based Programming tool written in node.js and using a web front end for wiring together hardware devices, APIs and online services in new and interesting ways.
Many extra nodes are available (see http://flows.nodered.org), and can be installed via the Menu - Manage Palette option. Due to the restrictions of snaps nodes that require extra access to files, ports, or have a binary component, may NOT work or install correctly - unless run in "classic" mode. This is not the default.
Generate an embeddable card to be shared on external websites.
Choose your Linux distribution to get detailed installation instructions. If yours is not shown, get more details on the installing snapd documentation.
