Question

我有几个functions但我不知道如何在liberary中收集用户定义的函数以在nodeJs项目中重用它们？

Answer 1

你可以这样做：在首选文件夹中，创建一个类似user.js的文件然后，定义一个类，E6方式：

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，在您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;

之后，您将能够在您需要该课程的文件中使用您在课程中声明的功能，例如：

user.userFunctionThatDoesSomething(etc..);
