Some of the examples (in examples/) don't work anymore. I tested examples/modus-inline, and the displayed uri was "http:".

[graingert]

That's strange, what data is going into url.format that results in the failure?

[SpaceK33z]

The data going into it is:

{ protocol: 'http',
  hostName: 'localhost',
  port: '8080',
  pathName: '/' }

You can test this by navigating to examples/modus-inline, the instructions are in the readme there ;).

According to the node.js documentation you're using some wrong parameter keys it seems.

Looks good now, thanks!
