在Express 4和express-generator / bin / www中使用socket.io [英] Using socket.io in Express 4 and express-generator's /bin/www

问题描述

所以这里是交易：我正试图在一个快速项目中使用socket.io。 Express Js 4之后，我已经更新了我的express-genrator，现在应用程序的初始功能进入 ./ bin / www 文件，包括那些vars（www文件内容： http://jsfiddle.net/avMa5/ ）

So here is the deal: I'm trying to use socket.io in an express project. After Express Js 4 was lauched, i've updated my express-genrator and now the app initial functions goes into ./bin/www file, including those vars (www file contents: http://jsfiddle.net/avMa5/ )

var server = app.listen(app.get('port'), function() {..}

（请检查 npm install -g express-generator 然后 express myApp

(check it by npm install -g express-generator and then express myApp

据说，让我们记住socket.io文件如何要求我们启动它：

that being said, let's remember how socket.io docs ask us to fire it:

var app = require('express').createServer();
var io = require('socket.io')(app);

好的，但我不能在app.js里面做，像推荐的那样，应该在./bin/www命令工作在./bin/www这是我可以做的，让它工作：

Ok but i can't do it inside app.js, like recommended. This should be done in ./bin/www in order to work. in ./bin/www this is what i can do to get it working:

var io = require('socket.io')(server)

Ok thi的作品，但我不能使用io var其他地方，我真的不想把我的socket.io函数放在 www 文件。

Ok this works, but i can't use the io var anywhere else, and i really don't want to put my socket.io functions on www file.

我想这只是基本的sintax，但我无法让这个工作，甚至不使用 module.exports = server 或 server.exports = server 或 module.exports.io = app（io）在www文件

I guess this is just basic sintax, but i can't get this to work, not even using module.exports = server or server.exports = server nor module.exports.io = app(io) on www file

所以问题是：如何使用socket.io havin这个/ bin / www文件作为我的应用程序的起点？

So the question is: how can i use socket.io havin this /bin/www file as starting point of my app?

推荐答案

事实证明，这真的是一些基本的sintax问题....我从这个socket.io聊天教程 ...

It turns out it really was some basic sintax problem.... I got these lines from this socket.io chat tutorial...

on ./bin / www，刚刚 var server = app.listen（.....）

on ./bin/www, just after var server = app.listen(.....)

var io = require('socket.io').listen(server);
require('../sockets/base')(io);

所以现在我创建了../sockets/base.js文件，把这个小伙子放在里面：

so now I create the ../sockets/base.js file and put this little fellow inside it:

module.exports = function (io) { // io stuff here... io.on('conection..... }

是啊！现在它的工作...所以我想我真的没有选择其他比起启动socket.io里面的/ bin / www，因为这是我的http服务器启动的地方
目标是现在我可以在其他文件中建立套接字功能，保持模块化，以code> require（'fileHere'）（io）;

Yeah! Now it works... So i guess i really had no option other than starting socket.io inside /bin/www , because that is where my http server was started. The goal is that now i can build socket functionality in other file(s), keeping the thing modular, by require('fileHere')(io);
