由于能够使用 GUI，我目前正在使用 Node-Red 来实现我的结果，但理想情况下我想摆脱这个，只拥有 1 个无缝系统，而不是在系统之间来回移动
我当前的流程如下。

我之前设法编写了一个使用 websocket 来显示 mqtt 数据的系统，但我无法将其推送到 mysql 数据库。
最佳答案
不，您无法将 Node-RED 流编译/导出为独立应用程序。
我们正在努力将编辑器 GUI 与实际运行流程的后端分开，但这是针对 future 版本的。同时，您当前可以通过更改 settings.js 文件来禁用编辑器。
...
// The following property can be used to disable the editor. The admin API
// is not affected by this option. To disable both the editor and the admin
// API, use either the httpRoot or httpAdminRoot properties
//disableEditor: false,
