Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways.
It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click.
Step 1: Installation & Running
Type the following into the terminal:
curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs build-essential
sudo npm install -g node-red
At this point you can test your instance by running node-red. Note: you may get some errors regarding the Serial node - that’s to be expected and can be ignored.
Once started, you can access the editor at http://:1880/
