如何在nodjs中收集用户自定义函数？
这个问题在这里已经有了答案：
你可以这样做：在你喜欢的文件夹中，创建一个像user.js这样的文件然后，定义一个类，E6方法：
class Users {
//if you need a constructor, but it's not mandatory
constructor(username,email,otherParamYouNeed){
this.username = username;
this.email = email;
this.otherParamYouNeed = otherYouNeed
}
//then organize your user functions there
userFunctionThatDoesSomething(){
//do what you need
}
userFunctionThatDoesAnotherThing(){
// do what you need
}
}
//then export the class
module.exports = {Users}
之后，在你需要调用这些函数的文件中：
var {Users} = require ('/path/to/user.js');
//if you have constructor in your class
var user = new Users(username,email,otherParamYouNeed);
//if not
var user = new Users;
在那之后，你将能够在你需要该课程的文件中使用你在课堂中声明的功能，例如：
user.userFunctionThatDoesSomething(etc..);
