Node js:best to define entity class

?

If you start-to-use a-DB like MONGO, you might is better off creating objects with mongoose and that ' s personal preference as well. As for your example-

1) Export person

Module.exports = person;

2) Import person from another file

Const person = require ('.. /path/to/person ');

3) Create person with the? New ? keyword to call the constructor (very important)

cons T Mitch = newperson ( ' Mitch '

You Should read up on? javascript ' s prototype object.prototype object.create (obj) ?to Create objects and assign the new object ' s prototype as the reference being passed in to? object.create (obj)

Here's an example from MDN

Shape-superclass

functionShape() {

This. x = 0;

This. y = 0;

}

?

Superclass method

Shape. Prototype.move = function(x, y) {

This. x + = x;

This. Y + = y;

Console.info (' Shape moved. ') );

};

?

Rectangle-subclass

functionRectangle() {

Shape. Call (this); //Call Super constructor.

}

?

Subclass extends Superclass

Rectangle. prototype = Object. Create (Shape. prototype);

Rectangle. prototype. Constructor = Rectangle;

?

var rect = newRectangle();

?

Console.log (' is rect of instance of Rectangle? ' ,

Rect instanceofRectangle); //True

Console.log (' is rect of instance of Shape? ' ,

Rect instanceofShape); //True

Rect.move (1, 1); //Outputs, ' Shape moved. '
