我正在學習Nodejs。我想在URL中運行兩個腳本（一個是登錄，另一個是聊天）。當我運行npm start命令然後我的登錄頁面打開，當我運行節點index.js命令然後我的聊天應用程序工作。我想讓我的聊天應用程序在登錄後工作。因此，我應該在哪裏指定我的聊天索引，以便它可以工作。如何在節點js中運行兩個程序
我app.js在這裏
var http = require('http');
var express = require('express');
var session = require('express-session');
var bodyParser = require('body-parser');
var errorHandler = require('errorhandler');
var cookieParser = require('cookie-parser');
var MongoStore = require('connect-mongo')(session);
var routes = require('./routes/index');
var users = require('./routes/users');
var app = express();
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/app/server/views');
app.set('view engine', 'jade');
app.use(cookieParser());
app.use(session({
secret: 'faeb4453e5d14fe6f6d04637f78077c76c73d1b4',
proxy: true,
resave: true,
saveUninitialized: true,
store: new MongoStore({ host: 'localhost', port: 27017, db: 'nodechat'})
})
);
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(require('stylus').middleware({ src: __dirname + '/app/public' }));
app.use(express.static(__dirname + '/app/public'));
require('./app/server/routes')(app);
if (app.get('env') == 'development') app.use(errorHandler());
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
