我正在尝试获取可以在代码中随处可见的变量我找到了一个解决方案，但这不是很干净
//environment.js
module.exports.appName = "appName";
和我的 app.js
var express = require('express')
, routes = require('./routes/main')
, user = require('./routes/user')
, http = require('http')
, path = require('path');
var app = express();
environment = require('./environment');
app.configure(function(){
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.cookieParser('your secret here'));
app.use(express.session());
app.use(app.router);
app.use(require('stylus').middleware(__dirname + '/public'));
app.use(express.static(path.join(__dirname, 'public')));
});
app.configure('development', function(){
app.use(express.errorHandler());
});
app.get('/', routes.home);
app.get('/users', user.list);
http.createServer(app).listen(app.get('port'), function(){
console.log("Express server listening on port " + app.get('port'));
});
这样我的 var 工作，我可以在任何地方访问 environment.appName，但是 Y 会有更好的解决方案
谢谢
