NodeRed on Android | How To Use Node-Red on Android Smartphone
Node-Red is Visual programming tool, What is Visual Programming Language?
A visual programming language (VPL) is any programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation. For example, many VPLs (known as dataflow or diagrammatic programming) are based on the idea of “boxes and arrows”, where boxes or other screen objects are treated as entities, connected by arrows, lines or arcs which represent relations.

How To Run Node-Red on Android
Using the Termux app in the app store makes it easy to run Node-RED on Android devices. You can get it from the Play Store.
Install it, and run it. Then at the prompt type
apt update apt upgrade apt install coreutils nano nodejs npm i -g --unsafe-perm node-red node-redThen you can point a browser to
- You can also npm install other node-red nodes such as
node-red-dashboardin the standard way :
cd ~/.node-red npm i node-red-dashboard
volume-downkey is the ctrl key – so
vol-down-ccan be used to “break” a running app.
- The instructions above also install the
nanoeditor, which is useful for editing files.
For a discussion on autostarting apps within Termux – see this thread on the Termux Github project.
I have found this other app useful for autostarting Termux on boot – Autostart – No Root
You can also get direct access to various hardware on the device by using the extra Termux device plugins – which can then of course be accessed via
Node-RED using the exec command.
Note: you need to install both the add-on app, and also the add-on api in Termux.
Install add-on app – Termux:API from Play store.
Install add-on access into Termux
apt install termux-api
