Getting express.js to show a public folder
提问by Spentacular
I've recently built a quick one page app using express.js, and this is really my first js framework (actually, my first js project, so I'm really new to this). I've got a subscription to the new typography.com cloud fonts, and I'm having trouble locating the "fonts" folder that I place in the public folder. Is there a way I need to add the folder and specify a route?
我最近使用 express.js 构建了一个快速的单页应用程序，这确实是我的第一个 js 框架（实际上，我的第一个 js 项目，所以我对此很陌生）。我订阅了新的typography.com 云字体，但无法找到放置在公共文件夹中的“字体”文件夹。有没有办法添加文件夹并指定路线？
Here's my app.js file:
这是我的 app.js 文件：
/**
* Module dependencies.
*/
var express = require('express'),
routes = require('./routes'),
user = require('./routes/user'),
http = require('http'),
path = require('path');
var app = express();
// all environments
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(app.router);
app.use(express.static('public'));
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
app.get('/', routes.index);
app.get('/users', user.list);
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
I haven't made any changes to the routes at all, so they are just default.
我根本没有对路由进行任何更改，因此它们只是默认值。

Please use express.staticsetting:
请使用express.static设置：
app.use(express.static(process.cwd() + '/public'));
And place your fontsfolder in that publicfolder.
并将您的fonts文件夹放在该public文件夹中。

If you are using Heroku, you may want to look at this thread: Deploy Nodejs on Heroku fails serving static files located in subfolders
如果您正在使用 Heroku，您可能需要查看此线程：在 Heroku 上部署 Nodejs 无法提供位于子文件夹中的静态文件
The guy explain that he struggled with "__dirname" until he specified the last version of NPM in his package.json:
这家伙解释说，他一直在努力解决“__dirname”问题，直到他在 package.json 中指定了最新版本的 NPM：
"engines": {
"node": "0.10.11",
"npm": "1.2.25"
}
If that doesn't work, you might try:
如果这不起作用，您可以尝试：
// At the top of your web.js
process.env.PWD = process.cwd()
// Then
app.use(express.static(process.env.PWD + '/public'));
Instead of "__dirname"
而不是“__dirname”
Though, all that is probably useless if you already struggle localy.
但是，如果您已经在本地挣扎，那么所有这些都可能毫无用处。
