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.
From the installation directory, go edit the `data/settings.user.js`. For example:
```js
module.exports = (defaultSettings) => ({
lang: "de", // define the language as "de"
exportGlobalContextKeys: true, // override the `exportGlobalContextKeys` value
logging: { // replace the default logging option ...defaultSettings.logging, // this will reinject the default settings in logging
console: {
...defaultSettings.logging.level, // this will reinject the default settings in logging.console
level: "debug", // but here, we override the "info" level by "debug"
},
},
});
```
You can check the default settings Yunohost generates at `data/settings.js` and find the documentation for configuring Node-RED here: https://nodered.org/docs/user-guide/runtime/configuration
