How do I prevent Node.js / Express serving up my a

问题:

I never thought this would be a problem with Node.js and Express, but on a crazy whim I decided to type into a browser the location of one of the source files in my Node.js Express project - something like:

http://www.mywebsite.com/mynodejsapp/app.js

To my extreme horror, my application's source code popped right up, publicly available for all to see.

So, that aside: how do I stop it in Node.js / Express?

My setup code is pretty straightforward:

var app = express();
app.configure(function() {
    app.use(express.static('/home/prod/server/app/public'));
});
app.listen(8888);

To clarify, this is what my folder structure looks like:

/home/prod/server/
/home/prod/server/app.js
/home/prod/server/public/

All sorts of various files that are intended for public access live under /public. All of my server source code lives under /server/, and my understanding of Express's static folder configuration is that the static folder is the only place that Express happily serves up files from the filesystem from.

Any ideas?

From what you posted it really smells like the URL you entered is served by e.g. Apache/nginx/... and you did put your node app within the document root. The answer is simple in this (and any similar) case:

You never put any of your sourcecode files within the document root or another HTTP-accessible folder. In your case, /home/prod/server/app/public should contain only client-side stuff (HTML, CSS, Graphics, (minified) client-side JS) and nginx should not have anything above this folder as its document root.
