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: ```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 `__INSTALL_DIR__/data/settings.js` and find the documentation for configuring Node-RED here: **分发版本：** 3.1.11~ynh1 ## 截图  ## 文档与资源 - 官方应用网站： - 官方用户文档： - 上游应用代码库： - YunoHost 商店： - 报告 bug： ## 开发者信息 请向 [`testing` 分支](https://github.com/YunoHost-Apps/nodered_ynh/tree/testing) 发送拉取请求。 如要尝试 `testing` 分支，请这样操作： ```bash sudo yunohost app install https://github.com/YunoHost-Apps/nodered_ynh/tree/testing --debug 或 sudo yunohost app upgrade nodered -u https://github.com/YunoHost-Apps/nodered_ynh/tree/testing --debug ``` **有关应用打包的更多信息：**
