This is a skeleton app for creating an MVC application in express
The handler then calls a model file in the models folder with the request and response objects and a callback function.
The callback has two arguments. The first is error information and the second is the results.
The callback should then send the response as appropriate
The service object should callback to the model when finished.
The model should then callback to the handler.
In most cases the service object would be accessing database information.
The codeset has a sample accessed by http://localhost:3000/list/ This sample does not interact with a database.
