API Docs

paperboy.deliver(webroot, req, res)

Checks the webroot folder if it has a file that matches the req.url and streams it to the client. If req.url ends with a '/' (slash), 'index.html' is appended automatically.

Parameters:

• webroot: Absolute path where too look for static files to serve
• req: A http.ServerRequest object
• res: A http.ServerResponse object

The function returns a delegate object that provides the methods below. Each of those methods returns the delegate itself, allowing for chaining.

delegate.before(callback)

Fires if a matching file was found in the webroot and is about to be delivered. The delivery can be canceled by returning false from within the callback.

delegate.after(callback)

Fires after a file has been successfully delivered from the webroot.

delegate.error(callback)

Fires if there was an error delivering a file from the webroot.

delegate.otherwise(callback)

Fires if no matching file was found in the webroot. Also fires if false was returned in the delegate.before() callback.
