Node.js 为我的节点项目开发正确的结构和设计模式

导言

第一次使用Node并感谢所有帮助和改进

我已经开发了代码

第一个从帖子中获取数据

其次，验证API连接并获取密钥

使用第一个和第二个函数中的变量并将其发布到API

问题

这段代码正在运行，并且是后端的。然而，我并没有把MVC放在心上构建它，我希望有人能帮助我清理它，并更好地构建它

我是node的新手，希望我的第一个项目遵循整洁的MVC结构，我可以将其用作如何构建未来产品的想法

我拥有的

正如前面所说，代码可以工作，但是它都在根目录上的

index.js

中，因为它是我的应用程序的后端，我希望它位于名为

backend

的文件夹中，然后是文件夹或文件

index.js

要首先谈论设计模式，您必须将任何对象/服务提取为对象。而不是试图找到提取对象之间的关系-没有关系？没有设计模式，抱歉……不用担心，我们仍在努力学习构造代码和构建未来实现的最佳方法
