Node-RED

Description

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.

Install/Setup

Common Issues

When you first spin up Node-RED, check your container logs docker logs nodered and you might see something like this:

> [email protected] start /usr/src/node-red
> node $NODE_OPTIONS node_modules/node-red/red.js $FLOWS "--userDir" "/data"

fs.js:114
    throw err;
    ^

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

This can be resolved by fixing the permissions on the appdata folder, just run:

sudo chown $USER:$GROUP -R ~/.config/appdata/nodered
