How can I implement virtual directories with node.js and express?

Question

I want to use the express static server configuration for implementing an static server: ``` app.configure(function() { app.use(express.static(__dirname + '/public')); }); ``` But I want to map the URL `http://myhost/url1` to directory `C:\dirA\dirB` and `http://myhost/url2` to directory `C:\dirC` How can it be implemented using express.static?

Accepted Answer

Depending on how many directories you're planning to map this way, you could simply make symlinks for those directories in your `public` folder.

In Windows:

```
mklink /D c:\dirA\dirB public\url1
```

In Linux or OSX:

```
ln -s /dirA/dirB public/url1
```

Then your static assets server should serve from those directories transparently (I've never tested on Windows but I don't see why it wouldn't work).

Alternatively, if you wanted to include some kind of dynamic routing, you could write your own middleware to replace `express.static` which is actually `connect.static` under the hood. Take a look at static.js in the connect source and see how it's implemented, it should be fairly straightforward to write your own variation.
