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.

Features

• Browser-based flow editing
• On-click deployment of the flows
• Over 225,000 modules available
• Custom JavaScript functions can be written

Override the default settings

From the installation directory, go edit the __INSTALL_DIR__/data/settings.user.js. For example:

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 __INSTALL_DIR__/data/settings.js and find the documentation for configuring Node-RED here: https://nodered.org/docs/user-guide/runtime/configuration
