Javascript 如何合并两个文件API（Node.js）

我是node.js和MySQL的初学者，我刚刚开始设置和尝试一些基本代码。 我发现这两个API需要实践，一个是CRUD数据库的API，另一个是判断用户登录/注册的API。我尝试合并这两个文件的API，结果出现了问题。我认为当前的问题是配置文件（conf.js）。我计划编写一个函数，然后包装任何文件并再次使用，这样配置文件可能不会冲突，但我不知道如何启动

这是我练习的两个API教学URL

您必须正确地重构它们。您只需要一次文件就可以开始了。为什么要用它两次

在一个文件中重构它们，而不是在不同的端口上侦听它们。完成后，您可以向我们显示代码，以便我们可以在出现问题时进一步修复它

从index.js开始，将app.js与之合并，但要小心一点。我认为自己做这件事你会从中学到很多东西
