有没有办法从节点红色转换为纯代码？

Question

由于能够使用gui，我目前正在使用node-red来实现我的目标，但理想情况下，我想摆脱这一点，只希望拥有1个无缝系统，而不是在系统之间来回移动

我的当前流量如下。

它包含如下显示

我曾经设法使用websocket编写系统来显示mqtt数据，但后来无法将其推送到mysql数据库中。

否，您不能将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与实际运行该流程的后端分开，但这是针对将来的发行版的。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
