javascript - NodeJS Object Require -

scenario: login account, , player object populated data db. object has methods update db.

issue: what's best way define such object? how define node can use these methods @ will? need pass player object parameter or have re-require (will re-define object?) req parameter "expire" or have wrong scope?

module.exports = {     createplayer:player }  function player(id,con,mysql,req) {     this.id = id;     this.x;     this.y;     this.con = con;     this.mysql = mysql;     this.req = req; }  player.prototype = {     move:function() {      } } 

and lastly, how require , initialize node?

var player = (new require("player")); //this guess honest 

player.js

function player(id,con,mysql,req) {     this.id = id;     this.x;     this.y;     this.con = con;     this.mysql = mysql;     this.req = req; }  player.prototype = {     move:function() {      } }  module.exports = player; 

use in file now

var player = require("./player");  // create player instance var p = new player(id,con,mysql,req);
