# Node-RED for YunoHost [](https://dash.yunohost.org/appci/app/nodered)   [](https://install-app.yunohost.org/?app=nodered) *[Lire ce readme en français.](./README_fr.md)* > *This package allows you to install Node-RED quickly and simply on a YunoHost server. If you don't have YunoHost, please consult [the guide](https://yunohost.org/#/install) to learn how to install it.* ## Overview 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 `/opt/yunohost/nodered/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 `/opt/yunohost/nodered/data/settings.js` and find the documentation for configuring Node-RED here: https://nodered.org/docs/user-guide/runtime/configuration **Shipped version:** 3.0.2~ynh1 ## Screenshots  ## Disclaimers / important information YunoHost's permissions system allows you to select which users can have access to Node-RED: * `main` permission protects `/admin`, the flows editor. The administrator is chosen during installation ; * `ui` permission protects `/ui`, the dashboard allowing visual interface for the flows. Public access is chosen during installation ; * `endpoints` permission protects `/`, for API-like endpoints. Public access is chosen during installation. If you have upgraded Node-RED beyond v2, check that these permissions suit you in your YunoHost admin panel. ## Documentation and resources * Official app website: * Official user documentation: * Upstream app code repository: * YunoHost documentation for this app: * Report a bug: ## Developer info Please send your pull request to the [testing branch](https://github.com/YunoHost-Apps/nodered_ynh/tree/testing).
