NodeJS - multiple objects split across multiple files but in the same namespace

I am writing a multiplayer board game server in NodeJS, and I have several different objects like Game, User, Board etc. Currently, all of these objects reside in a single 'sever.js' file which is executed by NodeJS.

As my project grows, this single file is becoming increasingly crowded and hard to navigate.

What I would like is to split these objects into multiple js files, but without having to开发者_运维百科 use the require function all over the place.

I wish to continue creating objects like this -

game = new Game();

And not this -

game = new (require('game')).Game()

--

Edit:

What is the correct NodeJS way of doing things?

Well, there are a few small things you can do.

First, when you define your class in another file (to be required) you define module.exports directly, i.e.

module.exports = function Game() {...};

And, then instead of:

game = new (require('game')).Game()

You can do:

game = new (require('game'));

Or, what I prefer, is to define all the requirements at the top:

var Game = require('game'),
    User = require('user');

// Use them:
new Game();
new User();

You could create some fancy loader that traverses the directly and automatically requires all JS files, but I really don't think it's worth it.

You can use global. in Game.js:

global.Game = function(){};

in User.js:

global.User = function(){};

in main.js:

require('Game.js');
require('User.js');

var game = new Game();
var user = new User();

You can load them at the beginning:

var Game = require('game').Game;
// Do a bunch of stuff
var game = new Game();

However, I personally wouldn't. Can't say exactly why I don't like the idea, but I don't.
