Question

我在/ cmd /中获取文件以从index.js读取正确的函数时遇到问题。我知道我需要在index.js中以某种方式使用module.exports，但是我不确定它的语法。本质上，我希望能够使用在profile.js中发送命令的用户的化身和用户名，但是我需要为此使用Discord.Client，但我不确定如何这样做。预先感谢。

我建议您不要使用module.exports，因为当您需要index.js时，请再次运行它。

您可以设置全局变量，以便在index.js需要profile.js文件时，它可以使用先前在第一个文件中声明的所有变量。为此，必须将要使用的变量存储在global对象中：例如，如果要与其他文件共享客户端，请设置global.your_var_name = client。然后，在另一个文件中，您必须像在文件中声明的那样键入your_var_name。

//index.js
global.client = saki;

//cmd/profile.js
client.blablabla...

我使用这种方法已经有一段时间了，我发现它非常有用，即使有人会告诉您您不应该这样做，并且还有更多“正确”的方法可以做到这一点。

希望这对您有所帮助，如果您还有其他疑问，请告诉我！
