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.
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for Linux Mint 18.2 (Sonya), Linux Mint 18.3 (Sylvia), and the latest releases, Linux Mint 19 (Tara) and Linux Mint 19.1 (Tessa).
You can find out which version of Linux Mint you’re running by opening System info from the Preferences menu. To install snap from the Software Manager application, search for snapd and click Install.
Alternatively, snapd can be installed from the command line:
Either restart your machine, or log out and in again, to complete the installation.
To install Node-RED, simply use the following command:
