If port can be converted to a number convert it

[gsf]

I'd like to set up a proxy server like so:

var httpProxy = require('http-proxy');

var port = process.env.PORT || 9876;
var proxiedHost = process.env.PROXIEDHOST || '127.0.0.1';
var proxiedPort = process.env.PROXIEDPORT || 8765;

httpProxy.createServer(proxiedPort, proxiedHost).listen(port);

If I set an environment variable for PORT I'm fine but doing the same for PROXIEDPORT breaks things because it expects a number instead of a string. Looks like node handles this in the net library with a handy toNumber function.

(Also, as an aside, it would be nice if the proxied host defaulted to 127.0.0.1 when missing that parameter.)

If you want to turn it into a number, you should use:

var proxiedPort = parseInt(process.env.PROXIEDPORT) || 8765;

I prefer

var proxiedPort = +process.env.PROXIEDPORT || 8765;

but I think others might get caught up on this as well, so it should be fixed in the project.

Fixed in master.
