fumble.http

provides a set of utilities for returning HTTP errors. Each method returns an HttpError instance, which itself extends the native Error class (which means you can access the stack prop on your error instance). Each error has the following two props

• statusCode {Number} - the HTTP status code (typically 4xx or 5xx).
• message {String} - the error message

fumble.http.create ([status=500], [message='Internal Server Error'], [options])

Generate an HttpError object where

• statusCode - an HTTP error code number. Must be greater or equal 400
• message - optional message string.
• options - extra options
• options.debug - additional error debug info set to error.debug property.
