            Bug ID: 57593
           Summary: Parsoid: Server doesn't handle 'error' event for
                    connect
           Product: Parsoid
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: Unprioritized
         Component: Web API
          Assignee: gwi...@wikimedia.org
          Reporter: krinklem...@gmail.com

When starting api/server.js and there is an error, it throws an internal node
module exception instead of handling the error.

This can be reproduced when, for example, an EADDRINUSE error is triggered in
case of some other random service using port 8000.
